Lvl. 1

• Gravity pulls things together.
• The Sun’s gravity keeps the planets going around it.
• The Earth’s gravity keeps the Moon near us.
• Orbits are paths in space made by gravity.

• Gravity is a force that pulls objects toward each other.
• Orbits happen when an object is moving and gravity pulls it into a curved path.
• Planets orbit the Sun due to the balance between gravity and motion.
• Moons orbit planets the same way planets orbit stars.

Hands On Activity: Gravity Dropping
Materials

• 2 Identical sheets of paper 
• 2 Identical Water Bottles (one that's completely full, one that's half empty)

Discussion Questions
Level 1

1. What does gravity do?
   Sample answer: Gravity pulls things together.
2. What keeps the planets going around the Sun?
   Sample answer: The Sun’s gravity keeps the planets going around it.
3. What keeps the Moon near Earth?
   Sample answer: Earth’s gravity keeps the Moon near us.
4. What is an orbit?
   Sample answer: An orbit is a path in space made by gravity.
5. Why don’t planets fly away into space?
   Sample answer: Gravity keeps pulling them toward the Sun.

1. What is gravity?
   Sample answer: Gravity is a force that pulls objects toward each other.
2. How does gravity help create orbits?
   Sample answer: Orbits happen when an object is moving forward and gravity pulls it into a curved path.
3. Why don’t planets fall straight into the Sun?
   Sample answer: Planets are moving forward while gravity pulls them inward, creating a balanced orbit.
4. What two things work together to keep planets in orbit?
   Sample answer: Gravity and motion work together to keep planets in orbit.
5. How do moons orbit planets?
   Sample answer: Moons orbit planets the same way planets orbit stars, using gravity and motion.
6. How is a moon’s orbit similar to a planet’s orbit?
   Sample answer: Both follow curved paths because gravity pulls them while they keep moving forward.
