Physical Science
We summarize the week's scientific breakthroughs every Thursday.
-
When atoms collide, new elements arise
Take note — there could soon be a new element on the block. By smashing atoms together, scientists have been expanding our periodic table of elements beyond what occurs in nature. Learn how scientists create them while answering questions and discussing how such innovations may help us in the future.

Neutrino-detection issues? Time to tree-cruit!
Physicists propose that trees may help detect high-energy subatomic particles called neutrinos. Learn how Earth’s atmosphere alters these incoming high-energy subatomic particles from space. Then, explore how scientists could use this interplay to develop new ways to detect high-energy neutrinos.

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.

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.
- Chemistry
A sweaty plant adaptation
Sweating has a surprising purpose for one desert plant. Students will learn about a chemical adaptation that allows the plant to collect moisture in an arid environment. They’ll answer questions about using videos to collect data and then draw molecular diagrams that illustrate the plant’s adaptation.
- Earth
Pink diamonds
Colliding tectonic plates might make your diamond blush. Learn how differences in crystal structure give rise to distinctive physical differences, such as the rare pink diamonds of Western Australia. Answer questions about the value of skepticism in science and discuss how uncovering the history of our planet can give us a treasure-hunting lead.
- Physics
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.
- Environment
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.
- Chemistry
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.
- Chemistry
Applying the ideal gas law
Summary: Students will review the ideal gas law and use a simulation to explain the assumptions made in a recent study about how climate change is impacting baseball. Learning Outcomes: Exploration of the cause and effect of manipulating conditions of a gas using a simulation, identifying relationships of variables using a mathematical equation and application of theoretical concepts to real-world examples.
- Climate
How heat and home runs are connected
Students will answer questions about the online Science News article “Baseball’s home run boom is due, in part, to climate change,” which explores how increases in temperatures boost home run numbers. A version of the article, “Climate change spikes baseball homers,” appears in the May 6, 2023 & May 20, 2023 print issue of Science News.
- Microbes
Building bread reveals physical and chemical changes
Many of the things people make — from concrete to bread — undergo physical and chemical changes during production. While making bread, students will learn more about the differences between chemical and physical changes and how the two are related.
