Impact Crater Simulation
Explore how an asteroid impact can affect Earth and cause mass extinctions, helping kids understand why many dinosaurs died while some animals survived.

Materials Needed:

• Large shallow tray or pan (to represent Earth)
• Flour, sand, or cocoa powder (to cover the tray like the ground)
• Small rocks or marbles (to represent asteroids)
  
  

Instructions for Parents:

1. Set the scene:
   Explain that around 66 million years ago, a giant asteroid hit Earth. This impact caused fires, dust clouds, and dramatic environmental changes, leading to the extinction of most dinosaurs.
2. Prepare the “Earth”
   Fill the tray with a layer of flour, sand, or cocoa powder. Smooth the surface so it looks like a flat “planet.”
3. Drop the asteroid
   Have your child drop a rock or marble from a height into the tray. Watch the crater form and notice how far the material spreads.
4. Observe effects
   Discuss how the impact throws debris everywhere, blocks sunlight, and can change the environment. Optional: lightly spray water to simulate rain or other environmental changes.
5. Connect to survival
   Talk about which types of animals might survive this kind of event. For example:
   • Small animals or those that can hide (like mammals and birds)
   • Animals with flexible diets
   • Creatures living in water or underground
6. Record observations
   Encourage your child to draw the crater, note what happened when the “asteroid” hit, and describe which creatures might survive and why.

Parent Talking Points / Connections to the Lesson:

• Level 1: “A big asteroid hit Earth and caused many dinosaurs to die. Some animals, like birds and mammals, survived because they were small or could hide.”
• Level 2: “The K–Pg extinction shows how sudden environmental changes can wipe out species that cannot adapt. Survival depends on traits like size, diet flexibility, and habitat. This impact reshaped life on Earth, leading to new ecosystems dominated by mammals and birds.”

Optional Extensions:

• Compare impacts: Drop asteroids of different sizes and discuss how bigger impacts affect survival.
• Survival chart: Have kids draw or list which types of dinosaurs likely died vs. which creatures survived and why.
