Do you have any suggestions for how I can help my middle school students understand and use the metric system? We struggle with this at the beginning of every year.  –E., Indiana

It’s hard for U.S. students to get a handle on meters, liters, and grams when in their everyday lives they are surrounded by references to miles, feet, inches, quarts, and pounds (one exception being a two-liter bottle of soda). We can’t change what’s on television or on the internet, but we can require that students use International System (SI) units and measurements in their science activities, investigations, and reports.

The first textbook I used had a chapter devoted to the metric system, so I would dutifully “cover” it at the beginning of the year, supposedly to prepare students for future investigations. The students memorized the prefixes, and there were exercises in measuring classroom objects. The chapter had a heavy emphasis on converting units from metric to English or vice versa. What a disaster! I felt like I was teaching more arithmetic than science. Even though we practiced measuring things with metric rulers, graduated cylinders, and balances, I found that later when it came time to actually apply those skills in investigations, my students had forgotten (or claimed to have forgotten) much of what they “learned.”

When I reflected on this, I realized that I had expected the students to master these concepts, skills, and vocabulary without a meaningful context for them. It seemed difficult for them to apply processes introduced at the beginning of the year to an activity weeks later. I was certainly teaching the material (with the lesson plans to prove it), and the students seemed to know the material at the time. But they weren’t learning it well enough to apply it to new activities without a lot of review and re-teaching.

So in the following years I changed my approach. I decided to introduce only those SI/metric measures that are commonly used: kilograms, grams, and milligrams; liters and milliliters; kilometers, meters, centimeters, and millimeters. That’s it. I mentioned that other units such as decigrams or centiliters exist but are seldom used. (I’ve traveled a lot in Europe, Canada, and Australia and I never saw anything measured in hectograms or kiloliters!)

I introduced or reinforced these units within the context of investigations, rather than as separate and isolated topics of instruction. When we came to an investigation requiring liquid measurements, we first practiced with graduated cylinders and discussed the relationship between milliliters and liters. Students had a section in their notebooks for notes and drawings on measurements that they could use as reminders in future activities. I also found that students knew more than I had assumed.

We didn’t spend time on problems converting miles to kilometers or grams to ounces. It’s not worth it, and now most smart phones, tablets, and computers have apps that do these conversions. Students should know which SI units correspond to the ones they are more familiar with in the United States. For example, in much of the world meat and butter are sold in kilograms instead of pounds, distances between places in kilometers, gasoline and milk in liters, and so on.

I always had a few students say “Why do we have to measure this way?” which is a good question. I would mention that science research around the world uses SI measurements. The United States, Myanmar, and Liberia are the only nations in the world that do not use SI as the official system of weights and measures. But I clinched the discussion by asking students, “Who likes to play with fractions?” Very few hands were raised. When the students compared adding 1/8 inch and 3/16 inch vs. adding 3 mm and 4 mm they were convinced.

The Science Teacher

Ever-increasing volumes of information from sensors, satellites, cell phones, telescopes, global information systems, and social media provide unprecedented opportunities for scientists, citizens, and students to investigate complex systems. Scientific progress doesn’t result from simply accumulating data. But there’s no doubt that big data is revolutionizing fields as diverse as astronomy, marketing, genomics, climate science, oceanography, social science, and health care. Big data has the potential to transform science teaching and learning as well. Our students can engage in the higher-order thinking involved in analyzing and interpreting large science data sets and designing their own inquiries to discover patterns and meaning in mountains of accessible data, as authors in this issue of The Science Teacher illustrate.

For nearly two years, NSTA Press has been pinning quotes from its books to Pinterest. Our followers often repin these interesting, informative, and often inspirational quotes. These are the books that have garnered the most attention. Are you following us on Pinterest?

NSTA has identified three major features of students who actually “Do” science.  The first of these is Human explorations of the natural world. The second includes Explanations of the objects and events encountered.  And the third requires Evidence to support the explanations proposed. These features should be incorporated in science teaching for all students to ensure that students experience the actual “Doing of Science!”

We want students (and teachers) around the world to experience science in every K-16 science classroom. If we’re doing it right, students will “question”, “think creatively”, and “gather evidence” continually to support the explanations. It is especially important that the validity of the explanations proposed be established. Such experiences with “science” are not typically taught to students by science teachers. All (both students and teachers) should share explanations and interpretations about objects and events which they themselves have encountered.

The use of textbooks, laboratory manuals, teacher lectures, and other quick fixes for teacher actions are all opposite examples of “doing” science. Evaluating what students merely remember and repeat individually and/or collectively does not result in real science learning. Students must formulate their own ideas, including minds-on experiences, to really understand all aspects of “doing” science.

G. G. Simpson explained the “doing of science” looks like this:

1. Asking questions about the objects and events encountered;
2. Formulating possible answers/explanations;
3. Collecting evidence in nature to determine the validity of the explanations offered;
4. Checking on other attempts made by other experts; and
5. Sharing the solution(s) with others.

“Science” is not like art and drama where teachers admire and/or criticize the performances of their best students. “Science” starts with unknowns and then seeking answers to explain them!

Finding bits of clay pottery made and discarded by people hundreds of years ago reminds me of how this useful material can be a valuable addition to a preschooler’s experience. Of the earth but not commonly found on playgrounds, clay could be regularly provided in a bin for sensory experiences or building material. It can be made into almost anything! I wrote about the process we used to introduce clay work in the Summer 2015 issue of Science and Children.

When children first encountered the clay indoors at a table, they were immediately drawn to this new material. After working with the clay, children realized that it stuck to their hands, and some began to purposefully coat their hands in a way they could never do with playdough. This same property made other children avoid the clay. Having a system to rinse off hands in a tub of water after clay work, and before washing them, helped children feel comfortable with the “stickiness” of clay, and saved the excess clay so it didn’t get washed into the drains. Because the children were so used to the feel and texture of playdough, it took some time for them to capably shape it into balls, snakes and castles.

We made sticks available and the children incorporated the two materials. It was interesting that the class of older twos and the class of fours both approached the materials in the same way–sticks stuck into a base of clay. In the fall I will introduce the clay on the playground and see what the children do with it as they have even more time to learn its many uses. It can be used to model 3D forms, draw on its surface, and paint with in a watered down form. Will they incorporate sticks and leaves, decorate it with pinecones or knead in sand to create a new building material?

The Senate debate on the reauthorized Elementary and Secondary Education Act (known as No Child Left Behind) could start on July 7. According to Education Week, Senate Majority Leader Mitch McConnell has officially scheduled the bill—the Every Child Achieves Act (S. 1177)—for floor action following the July 4 recess.

This action comes days after 10 major education groups—including the National Education Association, the American Federation of Teachers, the Council of Chief State School Officers, the American Association of School Administrators, National PTA, and the National Association of State Boards of Education, sent a letter to Senators urging immediate action on the bill.

As reported in the April 17 NSTA Legislative Update, thanks to the leadership of Senator Al Franken (D-MN), Mark Kirk (R-IL), and Patty Murray (D-WA), an amendment to include a dedicated STEM K-12 program in the Every Child Achieves Act was adopted (by a vote of 12-10) when the bill was considered by the Health, Education, Labor and Pensions (HELP) Committee. This will ensure that states would continue to receive dedicated support for STEM activities from the U.S. Department of Education. The language stipulates that each state would receive formula-based funding to support partnerships between local schools, businesses, universities, and non-profit organizations to improve student learning in the critical STEM subjects. Each state would choose how to spend and prioritize these funds, which can support a wide range of STEM activities from in-depth teacher training, to engineering design competitions, to improving the diversity of the STEM workforce.

The Every Child Achieves Act also retains the current federal testing requirement—students would continue to be tested in English and math in third through eighth grades as well as once in high school, and science tests would also be administered three times between third and 12th grade—but the language does away with the current NCLB accountability provisions and allows states to develop their own accountability systems.

Read the April 10 NSTA Legislative Update on the Every Child Achieves Act.

In order for the comprehensive STEM initiative in this legislation to move forward, and provide federal funding for STEM programs to the states, it is critical that Senators hear messages of support for STEM education from constituents.

We have set up a sample letter, which you can personalize and send directly to your Senators, on the STEM Education Coalition website to help you do this. Please take a moment to contact your Senators now

In the House, National Journal is reporting that House leaders will also be bringing their bill to reauthorize No Child Left Behind (the Student Success Act) back for floor debate, and will allow new amendments that would allow schools to keep federal money but opt out of the federal regulations that come with it, and a possible amendment to create a voucher system. The bill was on the House floor earlier this spring, but was pulled from consideration by House leaders before a vote on final passage.

Senate Appropriations Sub-Committee Advances Education Funding Bill: Both the House and Senate Appropriations LHHS/Education subcommittees have passed their FY 16 spending bills, and once again House funding for the Math and Science Partnership program at the U.S. Department of Education was eliminated. Report language on the House LHHS Education bill follows:

Mathematics and Science Partnerships. “The Committee recommends no funding for Mathematics and Science Partnerships, which is $152,717,000 below the fiscal year 2015 enacted level and $202,717,000 below the budget request. This program provides professional development for math and science teachers; these activities can be carried out under other authorities funded in this bill and through other federal agencies such as the National Science Foundation.”

The Senate education funding bill did provide continued support for the Math and Science Partnership program at the Department of Education, at $149 million. We are watching this activity and will stress that the final funding agreement include the Senate funding level.
