Change Matters experiments

Below are the links to some of the Science experiments we have looked at so far during our 'Change Matters' unit. 


The first is the Mentos and Coca Cola' experiment, where two guys put a large amount of mentos lollies into various bottles of cocoa cola. Can you remember why the reactions happen? 


The next is probably one of the coolest experiments ever. You've heard the effect helium has on your voice, but what about sulfur hexafloride? This gas is six times denser than air and gives an awesome sound effect to your voice! 


The final experiment we watched was the dry ice experiment. Who knew air could freeze and unfreeze before your very eyes!
