Materials

• Clear jar
• Water
• Glitter
• Cotton
• Food coloring

Steps

1. Add water and food coloring to the jar.
2. Add cotton and glitter.
3. Layer colors to create a galaxy effect.

Science Concept

Galaxies are massive collections of stars, gas, and cosmic dust.

6. Crater Experiment

What Kids Learn

How meteorites create craters on planets and moons.

Materials

• Tray of flour
• Cocoa powder
• Small rocks

Steps

1. Cover flour with a thin layer of cocoa powder.
2. Drop rocks from different heights.
3. Observe the craters formed.

Science Concept

Meteor impacts create craters on planetary surfaces.

7. Make a Sundial

What Kids Learn

How people used the Sun to tell time.

Materials
