Energy Pyramid

Build an energy pyramid; see why only 10% of energy moves up each level and why there are fewer top predators.

Snap atoms into molecules (water, oxygen, methane) and see why some combinations are stable.

Heat and cool particles and watch them shift between solid, liquid and gas; the temperature graph explains...

Run kitchen reactions (baking soda and vinegar, rusting); count atoms before and after to see mass is conserved.
