Five reasons we love science

By Claire Reinburg

Posted on 2011-07-14

Summer can be a time of rest and renewal and an opportunity for teachers to fit in professional pursuits like reading that new book, taking a workshop, or conducting an in-depth study. In the July 2011 issue of NSTA’s Book Beat, we invite readers to take a step back to reflect and reconnect with a few of the many reasons to love science and science teaching. Click over to read the full July issue, where you can also download this month’s free lessons and chapters.
1. Science Has Stories
Stories can be wonderful teaching tools, and science has stories galore—from children’s books about science to case studies by scientists. Children’s trade books linked to science have the power to draw students in to explore, question, discuss, and investigate. Karen Ansberry and Emily Morgan’s Picture-Perfect Science Lessons (grades 3–6) presents powerful strategies for connecting reading and science in a natural way in the elementary classroom. “Dr. Xargle’s Book of Earthlets” engages students through reading a children’s book that has memorable and sometimes hilarious examples of inferences versus observations. Students then practice those skills through several hands-on activities. For grades K–8, Richard Konicek-Moran’s Everyday Science Mysteries presents students with stories about a mystery from everyday life that science can help them solve. “The Little Tent That Cried” helps students see the water cycle in a natural situation and then suggests activities to give them a deeper understanding of evaporation, condensation, and humidity. Start With a Story: The Case Study Method of Teaching College Science, edited by Clyde Herreid, is chock full of case stories that will engross college students, including “Of Mammoths and Men: A Case Study in Extinction.”
2. Science Has Mysteries
Students of science often start delving into a topic after encountering a puzzling or confusing event. Everyday Science Mysteries books use perplexing everyday events to engage students and invite them to investigate what’s going on in the “story.” The baffling and the unfamiliar can intrigue students and spur them to take on the role of investigators. In “Exploring the Mysteries of Fingerprints” from John Eichinger’s Activities Linking Science With Math, K–4, students use investigative techniques to identify and classify their fingerprints based on shape before they collect and classify fingerprints from classroom surfaces after predicting likely locations. A biology mystery from Thomas O’Brien’s Even More Brain-Powered Science titled “Resurrection Plant: Making Science Come Alive!” has students observing and studying a “resurrection plant” to investigate why these dry-looking, fernlike plants appear to come back to life when placed in water. The discrepant events in all three books of the Brain-Powered Science Series are sure to motivate the sleuths in your class.
3. Science Can Make Us Laugh
Using humor in science teaching can be a good way to lighten up the classroom atmosphere while still keeping the focus on learning goals. Take a cue from NSTA Press author Bill Robertson, who artfully weaves humor and serious science content in his Stop Faking It! Series. You’re always in for a treat with a Stop Faking It! book, and now there are nine to choose from.  From Robertson’s irreverent humor interspersed among the solid science explanations and activities to clever cartoons by illustrator Brian Diskin, you can laugh your way to better understanding of physics from Force and Motion to Chemistry Basics. Check out “Round and Round and Round in the Circle Game” from Force and Motion: Stop Faking It! for text and illustrations sure to give you a chuckle or two. Or explore the ingenious “Metaphysical Illustrations” by award-winning artist Tomas Bunk in Quantoons (grades 9–12), by Arthur Eisenkraft, and Larry Kirkpatrick. The book combines challenging physics questions with intricate drawings in a collection of problems that ran in Quantum magazine. Feast your eyes on the clever text and art in “Fun With Liquid Nitrogen” and “Laser Levitation.” It’s good to laugh while you learn!
4. Science Challenges Us
Science teachers love the challenge that studying science brings, from exploring a nearby stream to pondering the significance of the latest fossil finds from Colorado or China. Crafting just the right lesson for the group of students in your classroom is another challenge that science teachers take on every day. For an inspirational read on how one talented teacher approaches this challenge, read Cary Sneider’s chapter on “Examining Students’ Work” from J Myron Atkin and Janet Coffey’s Everyday Assessment in the Science Classroom. You’ll come away from this thoughtful piece with new insights about course adjustments you could make that will enhance you and your students’ learning experiences.
5. Science Is Everywhere
In her classic teacher resource Ten-Minute Field Trips, Helen Ross Russell writes that “youngsters who learn to ask questions, observe, set up possible answers, experiment, keep records, and think independently will grow up finding life challenging and worthwhile. They will also have the ability to adapt to a changing world.” Science teachers help children see that science is all around them and that even the smallest patch of grass or pavement can reveal volumes about their world. To reconnect with your inner explorer and consider new ways to use the school grounds as a teaching laboratory for young scientists, read Russell’s chapter “Of the Value of Saying ‘I Don’t Know.’” Check out the free sample chapters of Schoolyard Science, Inside-Out, and Outdoor Science for more practical ways you could incorporate brief outdoor treks into your science lessons.

Connecting with families over the summer

By Peggy Ashbrook

Posted on 2011-07-12

Child exploring what happens to wet chalk on blacktop.At the end of the school year I gave each preschool student’s family (about 58 of them) a note and a self-addressed stamped envelope in the hopes that they would write to me to let me know about any explorations their child experiences over the summer. Any exploration—deconstructing chalk on the driveway, blowing bubbles on the back step, discovering an anthill in the park, or digging for “fossils” at a museum—because the information will be useful to other families, and a record of what young children can do and learn about human-made and natural places in the world.
By asking them to fill out the following information and mail it to me, I hoped to inspire the parents to talk with their children, and have the children reflect on their experiences.

Summer Exploration Passport Page by _____________________________
Where did you go? List the name, address and website for this location, or just let your child describe it.
What did you see, hear, smell and touch? Write and draw about your experience.
Is there anything you would like to know? I would like to find out….________________.
I put the pages in a notebook for all families at this parent-run cooperative preschool. It’s a way of collecting family natural science experiences as told by young children to share with, and inspire, others.
So here it is, a month later, and I have two entries:
One child (dictated to a parent) said that she went to a Market in the city and saw cool hats and sunglasses, lots of dogs, held her nose when she went by the “really bad smelling fish”, saw pretty flowers and ate good hot dogs. She advised that one should wear a hat because it gets hot.
A dried flower with seeds.The other sent a flower, wrapped up in tissue, for me to help her identify. Unfortunately the flower body had dried and crumbled. Other than looking very pale in color I had no clue. Fortunately, there were seeds. So I planted them, wrote back suggesting that she check a flower identification book at the library to see if she can find her flower, and that I would let her know if anything grows.
I wonder if any other families will send me a page describing their explorations. Do you think an email letter halfway through the summer would get more responses? Should I send an email with a photo of something interesting I’ve seen this summer and ask adults to share it with their children?
Peggy

Bell-to-bell learning

By Mary Bigelow

Posted on 2011-07-10

I was recently at a workshop where the presenter used the term “bell-to-bell teaching.” As a student teacher, I was embarrassed to ask what this means.
—Cory, Mobile, Alabama

Teachers can’t control the length of the class periods, but they can control how they use the time they have. The goal should be to maximize the learning time, from the beginning of the class period to the end (bell-to-bell). When I first heard of bell-to-bell teaching, I worried some teachers and administrators might infer teachers should “perform” or take center stage for the entire class period. This seems at odds with the idea that class activities should focus more on what the students are doing. (It also sounds exhausting.) As I reflected on this, bell-to-bell learning made more sense to me.
All class activities should relate to the learning goals of the lesson and ultimately to the theme or big idea of the unit of study. Consider how time can be diverted away from learning:

  • At the beginning of each class period, the teacher takes attendance, returns papers, and collects assignments. He expects the students to wait quietly in their seats until he has finished, sometimes taking as long as 10 minutes.
  • In the middle of a class period in which students are engaged in a science activity, the principal announces the winners of a school contest or election via the school’s public address system. It takes the teacher a few minutes to get the students’ attention focused back on the activity.
  • The teacher returns a test. She reads each question and provides the correct answer with no discussion. She then announces there is not enough time left in the period to start the next unit, so she tells students to use remaining 20 minutes as a study hall.


Teachers can help students take responsibility for using class time purposefully to meet the learning goals through guidance and modeling. One method I found effective was to post an agenda. When the students came into the lab, they knew what the learning goals were, what activities they were going to work on in class, what needed to be turned in, and what materials they needed (pencil, science notebook, paper, textbook, etc.).
Bell-ringers are brief activities used at the beginning or end of the class period to engage the students and focus their thinking. For example, at the beginning of the class when students enter the room, they could answer a question about the previous lesson, read a brief description of the upcoming activity, or use their notebooks to respond to a visual prompt or current news item. This gives the teacher time for taking attendance or checking homework. During the last few minutes of class, students could write a summary or a brief response to a question for the teacher to check for understanding. This also gives the teacher time to scan the room to make sure lab materials are cleaned up and put away. These exit activities get students to focus and reflect, instead of dashing from the end of one class to another without “packing up” their thinking. For more examples of bell-ringers, see my blog post, Activities Get Students Focused
Transitions between activities can also be a source of down time. Class routines can help students to stay on task. For example, students should have routines for cleaning up after a lab activity, turning in assignments, and moving between group work and large-group activities.
Interruptions and distractions are also obstacles to bell-to-bell learning. Cell phones or other devices should be turned off, unless they are being used as part of the lesson. Teachers often can’t do much about school-wide announcements, but you and the administrative staff could discuss how to communicate without unnecessary interruptions.
The day before a long break can be a challenge, too. Rather than a study hall or video, students might enjoy vocabulary games, a discussion of current events, or a lab activity.
When we complain our curriculum has too much to “cover,” why would we give up valuable class time for study halls, videos unrelated to the curriculum, coloring pages, or other busywork? Let’s make every minute count for learning, from the first bell to the last.

Science on a shoestring

Many of us can appreciate the theme of this issue. As a science teacher, I often wondered what it would be like to have a substantial budget for science equipment and materials. But as the authors of these articles show, science isn’t  just about how much “stuff” students use, but rather how they think using whatever is available.
I was reading this issue at the beach, so when I came to the article A Scientific World in a Grain of Sand I had a laboratory right at my feet! The article has some great suggestions for getting started on investigations of this material that is found just about everywhere, incorporating concepts from geology, physics, and chemistry. The website Sand from Pasadena City College has more ideas. If you want to see how an interest in sand turned into a long-term classroom project and lifelong hobby, see the website Communities of Sand. Perhaps you have a sample to include? If you start your own collection, try putting a small sample on a piece of clear contact paper and seal the sample with another piece. Students can examine the samples with hand lenses, sort them, or do other activities without spilling the sand into the crevices of your desks or lab tables!
On another beach/pool thread, Chromonoodles demonstrates how simple materials can be used in making models to help students with difficult concepts. The photographs are very helpful, too.  (SciLinks: Chromosomes/Chromatids)

The article It’s Elemental describes an interactive periodic table and activities to guide students through exploring elements and their properties, using 3-D graphics. This would be a terrific resource for students to use on laptops or other devices, as an alternative to print-based periodic tables. (SciLinks: The Periodic Table.  You can also search SciLinks for information on individual elements by name.)
In keeping with the theme of this issue, the authors of Simulating Science show how authentic science can be learned using simple materials (a list is provided) and microscale techniques. With these activities, the title could also be “Stimulating” Science. (SciLinks: Diabetes, Kidneys, Kidney Disease, Pathogens)
By the time students get to high school, they may have already done cookbook activities related to making slime. But Hydrogel Beads: The New Slime Lab shows how to extend the activity into an inquiry-based one in which students explore the properties of the material, which I learned has very practical uses. (SciLinks: Polymers)
The “Headline Science” department is not included in the online version of TST, but there are several topics this month that have related topics in SciLinks:

Be sure to look at the Connections  for this issue (July 2011). Even if the article does not quite fit with your lesson agenda, this resource has ideas for handouts, background information sheets, data sheets, rubrics, etc.

EOY activities

By Mary Bigelow

Posted on 2011-07-02

What can I do on the last few days of school? This year (my first as a teacher), my exams were over, projects were completed, and my grades were turned in. But after that it was hard to keep the students focused.
—Angie, Salt Lake City, Utah.

Time is a precious commodity. It’s hard to understand why some teachers stop their class activities several days before the last day. Everything is packed up and put away, the bulletin boards are down, and students sit around in “study halls,” even though they don’t have anything to study. (Although sometimes packing up before the last day is necessary. When we were changing buildings for a renovation project, we had to have things packed up by the last week for the maintenance staff to move). It’s hard to justify to parents and students why students should come to school on the last days of the year, if all the students do is watch movies, do busywork, talk to each other, or roam the halls.
Here are some learning-related alternatives:

  • You could ask them to work in groups to come up with a “guide” for next year’s class—something like The Top 10 Things You Need to Know About Chemistry Class or Physics Class FAQs (and Answers). You could make this open-ended or assign different topics to the groups (e.g., lab safety, study skills, lab procedures, difficult topics, or how to use a science notebook). You may need to model a few appropriate ideas before they start. The groups could share and debrief with each other. This could also be an informal evaluation survey, since you’ll get to see what they thought was essential or important enough to share. And be sure to share a composite list with your students next year on a bulletin board or via your website or blog.

  • Try out a new technology tool with the students. For example, lino is a web-based communication system mimicking sticky-notes on a bulletin board. The instructor creates a board and shares the URL with students who can post notes on it. Students work in teams using a computer, and can see what others are posting in real time. Then you debrief as a class or in larger groups, with all of the notes visible on screen. TodaysMeet is a Twitter-like application that captures what people are thinking during an event (the backchannel). If you show a video, for example, students can add their questions and comments (140 characters) as they watch. Of course, you can monitor these conversations to follow along and to add your own ideas. Both have a basic free version that requires instructors to log in. I’m sure that students would catch on quickly, and you could decide if this is worth using next year.
  • Vocabulary games, such as variations on Jeopardy or Pictionary. Some take a while to create, but a card sort or word splash is easy to put together. In charades, each team creates a pantomime of a vocabulary term or science process (it’s amazing what they can do with mitosis or Newton’s laws). Have a few prizes if you feel the need.
  • Lab activities or online simulations you wanted to do during the year but didn’t have time.
  • Some teachers give an end of year survey to students and debrief on the results.

Be cautious about having students assist with lab cleanup. You’ll have to supervise both those who are helping you and those who are not.
Keep the last day in mind as you start next year. Take photos or videos of activities and equipment during each unit, and have students write the captions at the end of the year. Prepare surveys and vocabulary activities in advance.
If grades are turned in, it may be hard to get students to participate especially if the whole year focused on points that “counted” for every activity. But I suspect that most students would rather have some sort of planned activity (even though they might grumble about it). In my school, the last day was a half-day to give out report cards and tie up loose ends. So I found the next-to-the last day was the more challenging one.

Find support and share resources at the Learning Center

By Peggy Ashbrook

Posted on 2011-06-30

As I was packing up materials and readying the classrooms for summer storage I reflected back over the year and thought about the next. Developing an on-going inquiry (or overlapping inquiries because more than one class uses the space at this school) is foremost in my mind. I want to find some resources to share with the classroom teachers (who are with the classes for the entire day) so we can plan together.
The NSTA Learning Center is a great place to find a professional community.Have you had time to use any of the free resources available from the National Science Teachers Association? I like being a member of NSTA because I get one in-print journal in the mail, and all the archived journals, as well as getting discounts on the books and conference registrations. For those who are not yet members, there is still free access to the NSTA Learning Center (click here) where many of the resources are available at no cost after free registration. The teacher-to-teacher forums are a comfortable place to ask questions and offer answers to questions.
The elementary section includes preK as the youngest end of the preK-to-Grade 2 continuum of early childhood. There you can find new  lessons, discuss classroom management issues in science, learn how others develop inquiry in their classrooms, find out about new resources to help you teach science and improve student achievement. Online advisors are available to help you navigate and become familiar with the Learning Center. You do NOT need to be a NSTA member to use many of the resources of the Learning Center including the discussion forums. The NSTA Learning Center is a good place to start preparing for the fall—look for reading material to be ready to teach particular topics and share strategies which worked well for you this past year.
To support your use of online professional development, let your administrators know about research firm Edvantia’s study on online professional development experiences offered by the NSTA Learning Center showing significant gains in teacher content knowledge and student learning among participants from the Houston Independent School District. Results show that the use of SciPacks—interactive web-based modules developed by NSTA and offered through its online Learning Center—significantly increased teacher content knowledge of Earth science and force and motion over the course of the study and gave teachers greater confidence in their ability to teach science.
Book cover "Hard to Teach Science Concepts".I’m joining the book group started by Kathy Renfrew, Elementary Math & Science Assessment Coordinator at the Vermont Department of Education, to discuss Hard to Teach Science Concepts: A framework to support learners, Grades 3-5 by Susan Koba with Carol T. Mitchell (2011, NSTA Press). (Yes, a little out of my normal range of preK-2 but I see it as a chance to learn what experiences my students in preK should have as groundwork.) I’m especially interested in the chapter, “Understanding Changes in Motion” by Rand Harrington with Susan Koba.
Kathy also began an on-going discussion of teaching physical science to kindergarteners. I’m curious—what has your experience been? Post your ideas or respond to any of the others at at the Force and Motion with Kindergarten thread in Elementary Science forum.

High-tech in Philadelphia

By Mary Bigelow

Posted on 2011-06-28

On the train, returning from a busy day in Philadelphia and the annual ISTE conference (International Society for Technology in Education), I finally had time to think.  It’s been a while since I’ve been to a technology-related conference and exposition, and I used the lens of science instruction to concentrate on the sessions and the vendors (even though I could be there for only one day). NSTA was there also, sponsoring a series of sessions and hosting a poster session about the Learning Center.
I had the pleasure of attending a session on the “flipped” classroom, presented by two trailblazers in this style of instruction, Johnathan Bergmann and Aaron Sams. If you haven’t been following them on Twitter (#flipclass) or their website, these two science teachers have taken advantage of digital tools to create a learning environment that gives students more responsibility for their learning. Basically, they record presentations and assign students to view them, take notes, and ask questions—as homework (this is the “flipped” part). The class period is then devoted to hands-on learning investigations, small group instruction, and individual conferencing. Their passion and enthusiasm are amazing, as is their generosity in sharing what they’ve done via their website and YouTube channel.

Other hot topics were cloud computing, professional development, and BYOD (Bring Your Own Device)–students use their own technology (e.g., laptops, netbooks, iPads, tablets, smart phone) in school.
The exhibit hall was an electronic wonderland—from interactive white boards to netbooks to lab probes to all sorts of web-based applications. But as I reflected on over 20 years of being involved in educational technology, it seems like there are two points of view. Do we use technology to help us do things better? I saw math drills and word games, attendance and grading software, interactive white boards and projectors to enhance presentations, online assessments, and other applications that have been around for a while, although upgraded with more bells and whistles.
Or—Should we use technology to do better things? Lab probes, creative tools, and access to primary source documents and data give students a different perspective of learning—that of a producer of knowledge, not just a consumer or looker-upper. They begin to see learning not as a mastery of facts but as a creative, problem-solving, challenging endeavor, with the teacher as partner rather than presenter. (This sounds more enjoyable to me as a teacher!). Hmm.
Other miscellaneous observations–Multitasking and backchanneling were everywhere. Just about everyone had a laptop, smartphone, and/or iPad. But none of the sessions I attended was interrupted by a cell phone ringing! ISTE had a nice conference feature—from the online program you could add an event to a personal planner that would sync with your calendar. The conference app also had the planner, maps, updates, links to chats, and a gallery to upload photos. I didn’t use the conference book they gave out.

Chemistry Now, week 16: biotoxins

By admin

Posted on 2011-06-28

image of Conus magus sea snail What can be a poison in one form can be therapeutic in another, which begins to explain why researchers would look to the biotoxins produced by warm water dwelling snails for solutions to chronic pain and a host of other neurological conditions in humans.

The venom of some snails has been shown to be 1000 times as powerful as morphine, a potent painkiller. Other snail venoms could be used as potent pharmaceuticals, and could be effective in treating postsurgical and neuropathic pain, and even accelerating recovery from nerve injury. But research into these potential uses is still in early phases. As recently as December 2004, the Food and Drug Administration (FDA) first approved a painkiller derived from cone snail toxins  under the name “Prialt.” Other drugs are in clinical and preclinical trials, such as compounds of toxins that may be used in the treatment of Alzheimer’s disease, Parkinson’s disease, and epilepsy.

We have reached the 16th week of the weekly, online, video series “Chemistry Now,” and we’re sticking with nature as a source of interesting video and lessons. As we’ve written before, please view the video, try the lessons, and let us know what you think.

Through the Chemistry Now series, NSTA and NBC Learn have teamed up with the National Science Foundation (NSF) to create lessons related to common, physical objects in our world and the changes they undergo every day. The series also looks at the lives and work of scientists on the frontiers of 21st century chemistry.


 

Video: In this 21st Century Chemist profile City University of New York chemist Mande Holford explains her research on the toxins produced by venomous sea snails, and her work to synthesize these long-peptide toxins for eventual use in treating chronic pain in humans.

Middle school lesson: In Vinegar and Baking Soda Investigation, students investigate the chemical reaction of vinegar and baking soda, demonstrating prior knowledge of concepts of chemical changes, and the laboratory skills of measuring volume, mass, and temperature.

High school lesson: In Mystery Solution Identification, students learn about solubility rules and use this knowledge to identify unknown solutions.
