Take a peek into thousands of frozen samples. Learners try to identify an image of a piece of frozen tissue. After choosing the correct answer, scholars find out more information about the American Museum of Natural History's Frozen...

What are the characteristics of Pluto? After many years, scientists are finally gaining knowledge about Pluto's surface. Using an exciting video from the SciShow Space series, learners investigate Pluto's surface by viewing images that...

Liquid nitrogen makes microscopic ice crystals, which make for a creamier food product than normal freezing. A gastronomical video explores nine different cooking techniques that are scientifically based. From food pairing to using...

Spangler invites a teacher in for this segment. She has developed some amazing demonstrations which use liquid nitrogen for elementary schoolers. She drops inflated balloons into a bowl of liquid nitrogen and the results are quite...

Use magnets, liquid nitrogen, and liquid oxygen in this quick experiment that illustrates paramagnetism and diamagnetism.

If air gets cold, does it turn into ice? Watch Joanne and Steve as they experiment with liquid nitrogen and a balloon full of air. What happens to the air is really quite remarkable! Explain this phenomenon in depth with your class after...

What is an insulator? What materials make the best insulator? Watch as Joanne and Steve conduct a simple experiment to see if a plastic cup insulates better than a styrofoam cup. Make a prediction: which do you think will be the better...

Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...

Pupils examine the use, costs, and the need for plant gene banks. The rationale for gaining ownership over scientific information and the implications of the developing nations' reliance on biotechnology is explored in this lesson.

Students explore the effects that extreme temperatures have on the material properties of solids. They investigate the properties of a material whose state depends on extreme temperatures and witness how it interacts with room...

Students determine the heat energy needed to vaporize (boil) one gram of liquid nitrogen.
