In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.
Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.
DNA the Easy Way
Source Institutions
This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
How can Clouds Help Keep the Air Warmer?
Source Institutions
