Exothermic, Endothermic, and Chemical Change
Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

Good Stress for Your Body
Stress the importance of the different types of pressure our mind and body experience in a lesson about how certain types of stress are actually necessary and good for our bodies. As astronauts and people with injuries can attest, not...
Cornell University
Electromagnets
Discover the connection between electric current and magnets. Scholars create electromagnets by passing a magnet through a coil. They experiment with different materials to determine the variables that affect the strength of the current.

Where Does a Plant's Mass Come From?
Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Can Boiling Make Something Freeze?
Use boiling as an avenue for freezing. Young scholars watch as liquid nitrogen removes heat from the ingredients for ice cream. As this happens, the nitrogen boils and the ice cream freezes—all in the same container. A little science magic!
