Been asked to help out tomorrow night
Someone’s already bagged the mentos and coke one
Any suggestions?
Needs to be with easily obtained items
Don’t have time to get much tomorrow, quick visit to asda only
Craters. Trays of sand or flour/cocoa powder, drop marbles from various heights, measure depth/width of craters. Or drop from same height and use different sized marbles.
Loads of ideas here http://www.crestawards.org/all-star-activities/. You could actually run the awards scheme, the kids love it.
Been a while now but I think the official website has lots of suggestions for all the badge work?
Crater suggestion above sounds good though.
Hope the leaders have done a full risk assessment.Lol.
No, I'm not kidding unfortunately!
Bicarb and vinegar is another explosive one.
Rockets. Some old 2l pop bottles, some flexible pipe. Gaffer tape the pipe to the bottle - this is the rocket launcher. The children make rockets out of A4 sheets of paper to fit over the pipe. Stamp on the bottle and the rocket should fly off if made well enough. Prizes for best design, furthest flyer, highest flyer etc... Good one with this is that they can work in 2/3s and keep modifying their designs and having test flights if each pair/group have their own rocket launcher.
If you had more time you could make a proper rocket launcher with copper pipe, bike pump valve and on/off tap. Pump up the pipe with a bike pump to build up pressure, release pressure with tap and the rockets go shooting off.
Here’s instructions for the full on rocket launcher... http://www.scienceinschool.org/2012/issue22/rockets
Measuring the speed of light with a microwave and a biscuit boost is a boss experiment for kids, although how old are beavers? If it's before cubs then possibly a bit too young for the concepts to have much resonance, but one to have up your sleeve.
Simple one for you.
Big target on the floor and give each one 5x pieces of A4 paper to create the best flying paper plane.

That was my first thought. Then the speed of sound using a loud noise at a known distance and a stopwatch.
And farting about with cornflower and water.
Look on youtube, there are loads.
matchbox racing cars, together with a few different inclined surfaces (you can have them rotating between stations to avoid having multiples) - so a 30 deg slope covered with carpet, glass, wood, sandpaper, etc. Release at top, see how far they roll. Which roll further, heavy or light cars (add weights with coins / bluetac)? Why? What is the force that makes something roll down a hill and what stops it from rolling in some cases? Why then do we choose rubber for car tyres, when other choices would have less friction and roll faster? Get each group to do a 1 minute talk on what they found.
Great ideas guys
Thanks
I’m only in helping as they are short of leaders
Need something that will take 10 mins as other leaders already organised a few things
Planes and treadmills?
We did this the other week. Colour spinners went down well.
Also a fun one with balloons part-filled with water. Show the beavers how a flame will burst a balloon, then hold one with water in over a beavers head. Hold your gas lighter at the base of the balloon (it won't burst if you do it right because the water cools the balloon and it doesn't burst).
Can't remember what our third activity was.
How about the pull a boiled egg through the neck of a bottle 'trick' using a match in the bottle, to demonstrate the match using up the oxygen & the resultant pressure difference forcing the egg into the bottle?
Or similarly, a floating tealight covered with a jar & the subsequent rise of water level in the jar as the oxygen is used up & the flame is extinguished.
