I have just been reading Mark’s blog on POE’s (Predict – Observe – Explain) . I am a big fan of POE’s and have done a number of them in science class. My favourite is the Alka Seltzer rocket. Each student is given a film canister an alka Seltzer tablet and some water. They simply combine a quarter of the tablet in some water and put the lid on the canister. They place the canister on the ground and wait for the explosion!
This is a great introduction to many physics concepts including chemical reactions, Newton’s laws and projectile motion.
This can then be followed up with a session in the computer lab where students graph their findings on excel and experiment with variables.
