We learned about autumn through varied experiments

Pumpkin volcano

We hollow it out and we carve a face 

We add baking soda, food colouring and vinegar

Now see the reaction 

We also made our own clouds and inflated our balloon using the same ingredients 

Pour a little vinegar into a plastic bottle

Use a funnel to put baking soda into a limp balloon and stretch the neck of the balloon over the top of the bottle 

Lift the balloon up and watch the reaction
