Experiment
The light, not the water
A dark bowl, a flashlight, and a dark room. Tilt the light. The bright patch moves. The water never turns gold by itself.
Science and discovery
Test the idea.
AJ.Jerrick takes things apart kindly. Each test below can be done at a table, with a grown-up if the work needs heat, glass, or a step outside.
Nature
Melt rises
A volcano is a vent. Melted rock is lighter than the stone around it, so it climbs. Warm soapy water in a bottle lets you watch bubbles rise — a small, safe cousin of that climb.
Space
Prints without wind
The Moon has no wind and no rain. A footprint can stay. On Earth, air and water erase prints. That difference is the discovery.
Invention
One fold changes the flight
Fold a paper plane. Throw it. Add one more fold on a wing. Throw it again. Write down what changed. That note is the invention page.
