Activity #1: Design your Skull.
Design your skull on the 3D print software. Follow your teacher's instruction.
Activity #2: Last Steps: Once your skull has been 3D printed, follow these last few steps.
Step 1: Add a small ball of clay to the inside of your skull.
Step 2: Inside the skull is “Crebrospinal fluid (CSF), clear, colourless liquid that fills and surrounds the brain and the spinal cord and provides a mechanical barrier against shock. ”*
Add water to the inside of your skull.
Step 3: Your head is connected to your neck which closes the bottom hole of your skull.
Tape the hole in your skull.
Activity #3: Testing
Directions: Using your two clay brains (one inside your 3D printed skull, the other without a skull) test them to see how the skull protects the brain. Take notes on what you observe during your experiments.
Test: Drop both brains on the floor.
Hit: Hit both brains with a ball
Activity #4: Make your own test.
Create your own test and record your observations.
