I'm getting ready to start up the nervous system
soon, and thought I'd share this intro activity that never fails to excite the
students. Use hot water, and it will have the same approx.temp, color,
consistency, and size as a real human brain!
Brain in a
Bag
1.5 (360 ml) cups instant potato
flakes
2.5 (600 ml) cups hot
water
2 (480 ml) cups clean
sand
1 gallon ziplock
bag
Combine all of the
ingredients in the ziplock bag and mix thoroughly. The resultant mix will have the same
approximate volume and weight (around 3 lbs) and consistency of a real adult
human brain. For best effect, mold it
into a brain-like shape and pass it around the room! It can re-warmed in a microwave for later
classes
