Make pinhole planetariums to fulfill Cub Scout Bear Elective 1b. This project involves hammers, nails, and flashlights, so it should be a hit with the Cub Scouts. Includes patterns for the pinholes.
When Scouts build a catapult, they can learn about physics and energy. An easy way to do this is with a small scale catapult.
An invisible ink demonstration will add fun to any Cub Scout meeting. If they haven’t seen this before, it will really get their attention. This would fit in with any science themed meeting or a communications themed meeting.
Catapult Cruzers recently sent me a couple of samples to review. Catapult Cruzers are toy airplanes which you put together and launch. These planes would be great for Scouts of any age. See the article for information about a free giveaway.
Webelos must learn about crystals to fulfill requirement 10 for the Webelos Scientist activity badge. I did this activity with DS, LC, and ZM when they were working on this badge. They really enjoyed it. When making the crystals, make sure they keep adding sugar until it really won’t dissolve anymore and it will be successful.
