LOOKING AT BUBBLES

Students explore aerodynamics and Bernoulli's principle by devising ways to keep bubbles aloft.

Learners study external and internal influences that affect behavior choices. They investigate the impact of those influences through a role play activity.

A demonstration of elephant toothpaste hooks pupils' interest as they complete multiple experiments with colors, smells, bubbles, and more. By the end, they understand the differences between physical and chemical changes in the world...

Reach out and grab something. Given the task of picking up objects at least two feet away, pupils design and build a grabber. The last activity in a series of five challenges requires learners to use information about fulcrums and levers.

How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...

This presentation starts with safety warnings for an experiment. Students will be introduced to the reaction that happens when magnesium is burned, the chemical background and the energy changes. Excellent examples and labeled reactions...

Pop! Does your class know that bubbles help us understand our planet, molecular structure, and more? The video teaches how to create colorful vortices on a bubble using basic equipment. Then it explains other interesting ways scientists...

Global warming ... greenhouse gases ... climate change ... sounds familiar, right? What about palm trees in Wyoming, or swimming in the sea near Antarctica? Science scholars discover the unbearable conditions Earth experienced during its...

Examples of the scientific method in everyday life include: trial and error problem solving, making a budget, cooking, and designing an advertisement. The video explains the steps of the scientific method and two examples of it in real...

Create jumbo bubbles and use them to teach about surface tension or interference, perfect for a physical science lesson on light or molecular attraction.
