- Physics
Let’s learn about gravity
Gravity is an attraction between objects with mass. The more massive the object, the more gravity it’s got.

Scientists Say: Respiration
Breathe in and out, that’s respiration. Have a cell break down sugars for energy, and that’s respiration too.

- Plants
How to grow your own science experiment
Does fertilizer help plants grow better? You might expect it to, but how can you know? This experiment will help you test it yourself.
- Physics
Scientists Say: Velocity
Velocity is more than speed. It is both speed and the direction in which an object is traveling.
