Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

You're bound to get a reaction from your classes with this experiment! Scholars perform several chemical reactions, make observations, and classify the reactions as single replacement, double replacement, composition, or decomposition...

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Why are bricks more likely to break than bend? Young science scholars peer inside a ceramic block and examine the effects of downward force at the molecular level. Learners can apply three different levels of force before observing their...

Young chemists love it when colorful solid products appear in a reaction vessel! Scholars discover the products that form during halide ion tests through a hands-on activity. Users go online and apply chemistry knowledge and reasoning...
