Interested in teaching your students how to make and support their science explanations in the classroom? We’ve got just the thing. The newest books in the Argument-Driven Inquiry Series from NSTA Press is here.

Argument-Driven Inquiry in Physical Science Lab Investigations for Grades 6-8 and the accompanying student manual offer 22 labs that align with the recommendations of A Framework for K-12 Science Education, as well as the Common Core State Standards for English Language Arts and Mathematics.

The labs provide students with the independence to investigate, analyze, and determine a conclusion. Labs include “Mass and Motion: How Do Changes in the Mass of an Object Affect Its Motion?” In the lab, students will study the motion of a pull cart to investigate what makes a system stable and what causes changes within a system, and then draw conclusions from patterns they observe.

The lab “Kinetic Energy: How Do the Mass and Velocity of an Object Affect Its Kinetic Energy?” asks students to use what they know about force and motion, patterns, and causal relationships to design and carry out an investigation and create a mathematical model explaining the relationship between mass, velocity, and force of impact.

With the argument-driven inquiry model students are asked to give presentations to their peers; respond to questions; and write, evaluate, and revise reports as part of each lab. The model is designed to be thought-provoking and multi-layered. Students must identify the task and guiding question, design a method and collect data, analyze data to develop an argument, and more.

“Each of the eight stages in the argument-driven inquiry instructional model is designed to ensure that the experience is authentic (students have an opportunity to engage in the practices of science) and educative (students receive the feedback and explicit guidance that they need to improve on each aspect of science proficiency),” the authors write in the first chapter.

Check out the free sample lab “Potential Energy: How Can You Make an Action Figure Jump Higher?” from Argument-Driven Inquiry in Physical Science: Lab Investigations for Grades 6-8 by Jonathon Grooms, Patrick J. Enderle, Todd Hutner, Ashley Murphy, and Victor Sampson.

What did you do before the navigation apps on your smartphone? Just a few (OK, several) years ago we were all using paper road maps, or finding our way using local landmarks. But think about the lack of landmarks for a WWII fighter pilot navigating over open ocean toward a pinprick of an island. How would you do it?

Find out in Flying the Beam—one of 10 posted videos in the Chronicles of Courage series. The 20-video series from the partnership of NBC Learn and Flying Heritage Collection uses the collection’s WWII airplanes and aviation technology as their focal point.

Use the video as a backdrop for student investigations into the electromagnetic spectrum, Morse code and digital communication, GPS, and the mathematics of navigation. The NSTA-developed lesson plan for this video elaborates on some of these ideas and gives you more to incorporate this video into your science course as well as collaborations with social studies and English language arts.

Stay tuned during the upcoming break for more lesson plans that will help you prepare for the end-of-semester schedules that can leave you in need of real-world applications that are a bit out of the ordinary!

Video
Chronicles of Courage: Stories of Wartime and Innovation “Flying the Beam” focuses on the use of low-frequency radio (LFR) range navigation during World War II.

Nuclear physics has an undeserved reputation for being tough for students. This article may reduce this “toughness” by showing how Einstein’s familiar equation E = mc² relates to the reductions in mass and enormous releases of energy that occur in the processes of nuclear fission and fusion.

We focus not on the mass of an atomic nucleus but on the mass per nucleon (a proton or neutron in the nucleus). If students can see the implications of how mass per nucleon varies from hydrogen to uranium, they will better comprehend nuclear fission and fusion.

In a typical fission reaction (Figure 1), a uranium-235 nucleus, after absorbing a neutron to become, momentarily, a U-236 nucleus, splits into nuclei of krypton and barium and releases three neutrons in the process. Note that the number of nucleons (protons + neutrons) before the reaction is equal to the number of nucleons after (true of both nuclear and chemical reactions).

You have to wonder about the engineering design advantages of a P-47 Thunderbolt airplane when WWII pilot Archie Maltbie recalls, “I flew the P-47 Thunderbolt in the 365th (Hellhawk) Fighter Group . . . and I know without doubt that I owe my life to [it].”

When the schedule leading up to holiday break becomes unpredictable, engage students in P-47 and the Turbo Supercharger—one of 10 posted videos in the Chronicles of Courage series. The 20-video series from the partnership of NBC Learn and Flying Heritage Collection uses the collection’s WWII airplanes and aviation technology as their focal point.

P-47 and the Turbo Supercharger delves into how this particular plane’s engine was designed to utilize exhaust gases to force more air into the engine, and thus increase the engine’s power. Boosting engine performance at both high and low altitudes gave the P-47 its advantage.

The companion NSTA-developed lesson plans give you a lot of ideas for how to use the videos as a centerpiece, or simply incorporate them into what you already do. Look through the lesson plans and adapt the parts most useful to you. We all know that everyone’s situation is just a bit different, so download the Word doc and modify at will to make it your own. After you give them a try with your students, let us know what you think! Suggestions for improvements are always welcome. Just leave a comment and we’ll get in touch with you.

Students should consume no more than 25 g (6 tsp.) of added sugar per day, recommends the American Heart Association (AHA 2016).

“Added sugars contribute to a diet that is energy dense but nutrient poor, and increase risk of developing obesity, cardiovascular disease, hypertension, obesity-related cancers, and dental [cavities],” the recommendation says (AHA 2016).

The AHA’s recommendation is timely. A total of 29.9% of high school students are overweight or obese, according to a nationwide survey by the U.S. Centers for Disease Control and Prevention (CDC 2016).

The 2015 survey of more than 15,000 students in grades 9–12 found that 13.9% of high school students were obese, and 16% were overweight (CDC 2016). In 1999, those percentages were 10.6% and 14.1%, respectively. For states surveyed, the 2015 obesity rates ranged from 10.3% in Montana to 18.9% in Mississippi. Overweight rates ranged from 13.3% in Missouri to 18.2% in South Carolina.

Added sugars are defined as “all sugars used as ingredients in processed and prepared foods and sugars eaten separately or added to foods at the table,” the recommendation says. “Sucrose and high-fructose corn syrup, both of which are made up of glucose and fructose… are the most commonly added sugars in the U.S. food supply.” Added sugars do not include “naturally occurring sugars … that are an innate component of foods (e.g., fructose in fruits and vegetables and lactose in milk and other dairy products)” (AHA 2016).

It will soon be easier to keep track of added sugar in packaged foods. The U.S. Food and Drug Administration recently changed the requirements of Nutrition Facts labels “to reflect new scientific information, including the link between diet and chronic diseases such as obesity and heart disease” (FDA 2016). Starting in July 2018, manufacturers will be required to list the grams of total sugars, grams of added sugars, and the Percent Daily Value for both.

Classroom activity
Have students track all of the added sugar in foods and drinks they consume for one week. For the second week, they should try to consume no more than 25 g of sugar per day.

Students should check Nutrition Facts labels on foods and beverages to find added sugar amounts and look for these other terms for added sugar, according to ChooseMyPlate.gov (2016): anhydrous dextrose, brown sugar, cane juice, confectioner’s powdered sugar, corn syrup, corn syrup solids, crystal dextrose, dextrose, evaporated corn sweetener, fructose, glucose, high-fructose corn syrup (HFCS), honey, invert sugar, lactose, liquid fructose, malt syrup, maltose, maple syrup, molasses, nectars (fruit nectar, peach nectar, pear nectar, etc.), pancake syrup, raw sugar, sucrose, sugar cane juice, and white granulated sugar.

When Nutrition Facts labels are not available or added sugars aren’t listed, students can use an online tool (see “On the web”) to find the amount of added sugar. After the second week, students can review their findings and write an essay about how well they adhered to the recommendation and the challenges they faced.

For another classroom activity on dietary sugar, read the September 2012 Health Wise column “Fight Obesity in the Classroom” (Bratsis 2012).
