Switching from cookbook labs to full inquiry

When I was in my undergrad science methods class, we learned about the value of inquiry in science. That was many years ago, and yet we’re still talking about the value of inquiry in science. I wonder if it’s because we still think of an “analog” situation: we do either cookbook labs (in which all students have to do is follow the directions) or we do full inquiry investigations (in which many students struggle). But rather than an either/or situation, this articles in this year’s Science & Children are showing how inquiry can be considered a continuum— confirmation inquiry (i.e., the cookbook), structured inquiry, guided inquiry, open inquiry. What differentiates these is the role of the students and teacher in asking questions, designing procedures, collecting and organizing data, and generating explanations and conclusions. The more input the students have, the “higher” the level of inquiry. The graphic in Inquiry Is Essential shows the relationship between levels of learner self-direction and directions provided by the teacher.
NSTA publications have many examples of how teachers can scaffold activities to guide students through the continuum, so that even a traditional activity can take on the characteristics of inquiry. (See The Many Levels of Inquiry in the October 2008 issue of Science & Children.) For this issue, I’ve noted the SciLinks topics that would support the content or include additional activities.

If you teach middle or high school and your students need some assistance in transitioning through the levels of inquiry, the strategies described in this issue could be helpful. The authors of Fire Up the Inquiry, Lose the Recipe, and Got Inquiry? describe how to adapt lessons to each of these levels–the same basic investigation, but with different levels of student input. The Mitten Problem discusses what to do when students have misconceptions that interfere with inquiry learning.  Overcoming Difficulties has ideas for working with bilingual students during inquiry lessons.  [SciLinks: Heat and Temperature, Insulation, Seed Germination, What Are the Parts of a Plant]
Water Pressure in Depth makes the point that although students may follow the directions and enjoy an activity, they may not really understand the science involved. By giving students more of a role in the activity, they may take on more ownership of their learning.  [SciLinks: Fluids and Pressure, Magnetism, Recycling]
One rationale that some teachers may have about inquiry is that there is too much content to cover. In 5 Strategies to Support All Teachers, one of the strategies is to connect the students’ ideas to the standards or curriculum goals. [SciLinks: Lakes and Ponds, Composting] From Adding Inquiry to Doing Science is a very honest discussion of a teacher’s efforts to transition from activities with predetermined outcomes to less predictable inquiry investigations. As she shows, younger students are indeed capable of higher-level thinking. [SciLinks: Autumn Leaves, Identifying Trees] Inquiry Follow-Up capitalizes on the curiosity and enthusiasm of pre-schoolers to investigate patterns of bird behavior at feeders. [SciLinks: Birds]
Two articles embed inquiry into the 5E model. Which Paper Towel Is Best? and Let’s Try It Out in the Air show how even a common investigation question can be kicked up a notch to incorporate more input from the students.[SciLinks: Wind Currents. See also The KidWind Project]
And check out more Connections for this issue (March 2011). Even if the article does not quite fit with your lesson agenda, there are ideas for handouts, background information sheets, data sheets, rubrics, and other resources.

Chemistry Now, week 9: the chemistry of green

By admin

Posted on 2011-03-22

Leaves changing colorsIt’s so simple, it almost seems magical. Leaves take in sunlight, convert it to sugars and starches, and the plant feeds itself and becomes the first link in a food chain that reaches all the way to the apple you chew and swallow on the way to the big game.

So, how does it work? Chemistry silly. In the case of plants, the leaves contain chlorophyll, which, when combined with water, enables the plant to photosynthesize, which is the process I described above. It’s not really that simple, but the lack of moving parts makes it seem so, and it certainly is quite elegant.

What happens when the chlorophyll goes away? Well, the plant enters a dormant phase, and the loss of the green pigment leaves behind (no pun intended) the beautiful colors you see when autumn rolls around each year. It’s early in the northern hemisphere to think about autumn, but for those of you south of the equator, have a look at what’s coming. Leaves changing from green to red, orange, yellow, and purple.

Enjoy.

We are into week nine of the weekly, online, video series “Chemistry Now,” and the chemistry of the garden works its way back through the flow of energy to chlorophyll and photosynthesis 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: “The Chemistry of Green” outlines the role of chlorophyll in photosynthesis, and explains why plants are green.

 

Middle school lesson: Chlorophyll Chromatography gives students an understanding of paper chromatography, allowing them to separate a mixture of pigments extracted from leaves.

High school lesson: Like the middle school lesson, this version of the lesson introduces the process of chromatography, but in this experiment, they separate a mixture of photosynthetic pigments extracted from leaves.

An interesting example of 21st century technology

In the video above, a third grader gets to use a rather striking example of 21st century technology to talk about some common topics in science, namely earthquakes and volcanoes.


I didn’t get the feeling that Duncan thinks we should not teach about dinosaurs and volcanoes, but instead teach about them and then beyond them. Frankly, if kids could grasp the actual science behind dinosaurs and volcanoes, they would be far ahead given all of the amazing science associated with volcanoes and dinosaurs. Sadly, most lessons in these areas usually focus on lower level (knowledge, comprehension, etc.) “facts” which are easy to assess with multiple choice instruments, yet allow little knowledge power beyond pointing and naming.

“..a pile of stones is not a house and a collection of facts is not necessarily science.”

– Henri Poincar

As I watched the video, I was encouraged by the pauses as the student studied the imagery on the globe. He is not reciting anything, but interpreting what he sees which in my book is at the highest levels of Bloom’s Taxonomy. In other words, complex scientific images are presented in a spherical (authentic) representation of the earth which in turn are then cognitively analyzed (separated into pieces) by the student, then reassembled (synthesis) into a reasonably coherent explanation of the relationship between the pieces (remember, this student is only 9 years old) .

A few things to keep in mind: 1) the sea floor is visible here, but in real life it is not; 2) the images are in false color; 3) his sister is selecting and moving different images of which the student does not always know what is next; 4) the globe is bigger (60-inch diameter) than the student so he cannot even see half the globe from his perspective; 5) the colors change and the oceans and continents switch between positive and negative space projections; and 6) the student is able to adapt to the images “on the fly” meaning he understands not only the individual concepts but their relationship to each other.

Science for all

For the past few years, the March issue of The Science Teacher has been devoted to this theme. As our classrooms become more diverse, we need ideas and research to help us share our passion for science with all of our students.
In this issue, as I read Teaching Science to ELLs, Part 1 and Part II, I had to stop several times to think how many of the strategies would apply to students who do not have a strong background in science vocabulary. The articles have rubrics and suggestions for differentiating instruction and assessment activities to help students use their skills and develop new ones. Science Vocabulary for All reports on a study on how “Collaborative Strategic Reading” can help students in an inclusion science class learn vocabulary.  The results were positive for all students, including those with disabilities. And the authors of A Learning Cycle for All Students describe some enhancements to the 5E model, adding an “Express” phase. This phase includes formative assessment that guides opportunities for differentiated instructions in the Elaborate phase.  [SciLinks: Eukaryotic Cells,Water Cycle, Carbon Cycle]

Technology can be adapted to meet students’ needs, as described in Personalizing the PC for Accessibility Selecting Software for Students with Learning and Other Disabilities recommends PhET Interactive Simulatons. Many of these simulations are individually included in SciLinks, and the entire site is a source for ideas.
After reading about the benefits of School Gardens, share an interview with a Horticulturist as a Career of the Month [SciLinks: Sustainable Agriculture]
Many elementary and middle schools have family science events, but the author of Creating a College-Going Culture describes such an event (actually a series of events) at a rural high school. High school students demonstrated their projects to parents and younger children. The event also provided the opportunity for high schools students and their families to talk with college students, motiviating more to think about the possibility of attending college. [Note: Rural students are also the focus of Finding Fairness for Rural Students in the March issue of the Phi Delta Kappan]

Teaching resources for the Japanese earthquake and tsunami

By Eric Brunsell

Posted on 2011-03-14

The devastating earthquake and tsunami in Japan is on the minds of all of us, including our students. The event and aftermath is tragic and the continuing nuclear emergency is a reminder of how fragile society can be. As educators, we can help our students make sense of these events and give them the opportunity to gain a deeper understanding of their world.
In their book, Comprehension and Collaboration, Daniels and Harvey provide a comprehensive vision of what inquiry can look like in the classroom. They describe the following components that can easily be used to bring the Japanese earthquake into your classroom.

Immerse: Invite Curiosity and Wonder
Introduce the topic by asking your students what they already know about the disaster. Follow this by brainstorming a list of “wonderings” that students have. You may want to set the context for the discussion by reading a small excerpt from a news article or by showing a video.

Investigate: Develop Questions, Search for Information, and Discover Answers
Individuals or small groups select and refine a broad question that they find interesting. You should help students with their question so that it provides an opportunity for them to delve into a topic and consider multiple sources of information. Students can use the web, library resources, and other media to search for information.

Coalesce: Synthesize Information and Build Knowledge
Students should identify a small number of “knowledge claims” that they have learned from their research. These claims should be supported by evidence from multiple media sources.

Go Public: Demonstrate Understanding and Share Learning
Students can share their learning in a variety of ways. For example, they can create newspaper articles, videos, audio podcasts, posters, or infographics.

The resources below provide a variety of perspectives on the Japanese earthquake. Some of the resources may not be suitable for all children.

Graphing in early childhood classrooms

By Peggy Ashbrook

Posted on 2011-03-14

The two comments on an earlier post on Collecting Data were about graphing in early childhood classrooms. My curiosity got the better of me so I investigated what some of the standards have to say about when it is appropriate to teach the concept of graphing.
I chose to list Virginia’s standards because that’s where I live, and Oklahoma because it has ranked first since 2003–2004 for serving the highest percentage of 4-year-olds in state-funded preschool.
It appears that most standards agree that preK is the time to introduce graphing—see the chart below.

This is not an exhaustive search—please chime in with any additions, corrections, or personal experiences!

Chemistry Now, week 8: cheeseburger chemistry: tomato

Posted on 2011-03-13

Close up of green and red tomatoes

Tomatoes…fiery color and cool completeness

How does a tomato go from green, marble-like sphere to juicy red brilliance? Chemistry, that’s how. In the case of tomatoes, the plant bathes the fruit in ethylene molecules when the fruit reaches an edible size, and this hormone triggers the fruit to ripen.

We are into week eight of the weekly, online, video series “Chemistry Now,” and the chemistry of food moves into the garden 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.

By the way, Pablo Neruda penned an “Ode to Tomatoes,” the source of our caption for the picture above:

“…the tomato offers
its gift
of fiery color
and cool completeness.”

I can’t think of anybody who better represented both fiery and cool personas than Neruda. Props to whoever knows why Neruda’s tomatoes showed up juicy and ripe in December; add your comment below.

The series also looks at the lives and work of scientists on the frontiers of 21st century chemistry.


Video: “The Chemistry of Tomatoes” (one in a 6-part Cheeseburger Chemistry series) outlines the role ethylene plays in ripening tomatoes (and other fruits); the role of lycopene in color change; and diffusion of gas.

Middle school lesson: The Ripening Tomatoes lesson gives students an understanding of how tomatoes ripen and what conditions allow them to ripen the best and allows students to observe a chemical change that happens in nature.

High school lesson: In this Ethylene Gas Investigation, students design and conduct an experiment  to observe the ripening of tomatoes under different conditions, evaluating the effectiveness of various strategies for ripening tomatoes including the role of ethylene gas.
