Mentos Geyser

You will need a roll of Mentos mints and a 2-litre bottle of diet Coke or Pepsi. Either diet or regular Coke/Pepsi will work for this experiment, but diet pop is less sticky when you're cleaning it up!

This activity is probably best done outside or somewhere where it is easy to mop! Carefully open the bottle of Coke. Position the bottle on the ground so that it will not tip over. Unwrap the whole roll of Mentos sweets. The idea is to drop all of the Mentos into the bottle of pop at the same time. One method for doing this is to roll a piece of paper into a tube just big enough to hold the loose Mentos. You'll want to be able to position the tube directly over the mouth of the bottle so that all of the sweets drop into the bottle at the same time. Sstand well back and drop all of the Mentos into the bottle at the same time and then move rapidl outof the way!

Carry out a heart dissection either as a demonstration or as a class practical using my worksheet.

Balloons

Why not have fun with your vocal chords. Im sure you have tried inhaling helium from a balloon but why not try carbon dioxide? It has the opposite effect-try it and find out!........

Methane bubbles

You will need a piece of rubber tubing, a 2 litre pop bottle, scissors, washing up liquid, a metre ruler, wooden splints sellotape and matches.


Firstly attach a wooden splint to the end of a metre ruler using sellotape. then cut the pop bottle down the middle. You only need the half that has the pouring end on it so you can dispose of the other part. You need to make a solution of 2 parts washing up liquid to one part water. Remove the cap off the bottle and place the rubber tubing inside attaching the other end to the gas tap. Pinch the tubing and place the washing up pre mixed solution into the half bottle so it is to a depth of about 10cm. Turn on the gas slowly. This should make the solution bubble and the bubbles should begin to rise into the air. Light the splint using the a match and ignite a bubble at arms length!

Borax
White Glue

In a beaker, add equal parts of the borax solution to equal parts of the glue solution. 1/2 cup of each will make a cup of slime. Add a couple drops of food colouring. Stir and knead the mixture. Your slime is now ready. Remember to wash your hands after playing.
