Stormy Days & Gamma Rays
Lightning crackles across roiling skies—a visible display of a thunderstorm's energy. However, these storms produce more energy than we can see. Scientists have now used new gamma-ray imaging techniques to reveal invisible energy streaming out of these natural light shows. Learn how gamma rays relate to the electromagnetic spectrum and explore the relationship between wavelength and energy, all while drawing connections to weather phenomena.
Convection Connections
For astronomers, watching convective cells of gas move on the surface of a distant star was kind of like looking at a lava lamp. Begin a unit on energy transfer by having students discuss lava lamps and the process of convection at work in them. Then have students read about the first observation of convection on a distant star and its potential scientific importance. Finally, students will brainstorm and diagram other examples of devices or natural processes that involve convection.
Arthropod Olympics
Scientists have discovered that Dicyrtomina minuta, a species of globular springtail, can perform the fastest backflip of any animal on Earth. In this activity, students will review how the team studied springtail backflips by analyzing high-speed footage. Then, they will research another Olympics-worthy competitor and describe how they’d measure performance in their imagined sports event.
A Nuclear-Shmear Campaign
Love mayonnaise or hate it, physicists just put this contentious condiment to work. Scientists struggle to study the behavior of matter during the process of nuclear fusion. Learn how researchers overcame some of these obstacles: They used a condiment with some surprisingly similar characteristics. It also helped them answer questions about the value of models for illustrating scientific processes.
Investigating phenomena with SEPs
To investigate why some meteors create persistent trails, scientists filmed the New Mexico sky for two years, recording streaks of light. Use shooting stars as an example phenomenon to generate student interest, wonder and questions. Then, have students explore how this phenomenon was studied using Science and Engineering Practices, while evaluating the study’s design, limitations and possibilities for future research. Finally, have students search for another phenomenon that interests them and begin asking questions about it.
The physics behind burbling water
The sound of running water can evoke thirst or make for a relaxing environment. Physicists have recently figured out what causes the burbling of this alluring sound. Get your students thinking critically about this everyday phenomenon and explore possible variables behind it. Then have them read about a recent scientific study that explains the physical science principles behind the burbling water.
Solving Hard-to-Reach Problems with ROVs
Remotely operated vehicles, or ROVs, are often used in environments that would be unsafe or difficult for people to enter to explore. In this activity, students will think critically about how engineering practices can be used to monitor environmental issues or solve real-world problems before designing and modeling an ROV that could be used to investigate a real-world problem impacting their local environment.
Green light means “go”
Just when we all thought we had evaporation all figured out, clever experiments shine a new light on old assumptions. A new study points to light having the ability to help sever bonds (a type of intermolecular force) between water molecules to boost evaporation. Learn how these findings support new scientific claims and challenge the old notion that light affects evaporation only indirectly, through heat generation.
Fluorescing frogs
Light up your class with examples of fluorescence, including recently found biofluorescence in many frog species. Learn about the discovery of fluorescing frogs, discuss the potential evolutionary advantages of fluorescence, answer questions about the chemistry behind fluorescence and perform a demonstration of fluorescence from common objects.
Syncing the power grid to renewable energy
How is the U.S. doing in its transition away from coal-fired power plants to renewable energy sources? Analyze state and national data to learn about the transition and one of the major challenges: keeping the grid stable as large power plants shut down.
Health Effects of Climate Extremes and Thermal Technology
Climate extremes are impacting human health and inspiring new technology. This guide provides lesson plans paired to recent news articles covering a new thermal fabric prototype and its ability to regulate temperature and how wildfire smoke impacts the air quality index and human health.
Not too hot. Not too cold
Staying cool in the summer and keeping warm in the winter may
become easier. Learn about a new thermal fabric prototype and its ability to regulate temperature,
answer questions about its design and function and discuss potential applications.
