Cubs Scientist - Fun Alternate Experiments

Report Copyright Infringement View in OSM UK View in OSM NZ

Description

Four experiments towards the Scientist badge that Cubs will love doing. My Cubs would happily have spent a further hour on these (particularly the last two) so you could happily split them over two nights.
Reactions - Pennies: a cut down version of the Rolls Royce experiment
Living world - Grow Something Disgusting: an experiment with a good scientific method to grow mould - it has the Yuk factor that Cubs seem to love! Note: they need to bring the bags back the next week.
Interacting With Energy - Lollipop stick catapults: Catapults and ping pong balls - almost endless fun
Reactions - Exploding Baggies: Speed, tension and a (small) explosion - what's not to like!

Resources

All resources are listed on the instruction sheet as well.

You need :
Pennies: White vinegar, salt, jam jars/containers, tablespoon, teaspoon, kitchen roll, water, dirty copper coins

Grow something Disgusting: bread, ziplock bags, water, biro, teaspoon

Lollipop stick catapults: lollipop sticks, elastic bands, milk bottle lids, ping pong balls

Exploding baggies: White vinegar, ziplock bags, kitchen roll, sodium bicarbonate (eBay) tablespoon, water

Instructions

See download sheet.

We combined these experiments with a pond dipping expedition, an electronics evening and a rocket building and flying session to cover all the badge requirements. There is no such thing as too much science :)

The badge requirements I have set up are a 'best fit'.

I hope your Cubs enjoy it as much as mine did - we all had a ball!
