Science Snacks is a website originally developed for secondary science teachers but is also being used extensively by primary schools and all of the activities are easily adaptable for use with younger children.

“Science Snacks are divided into easy-to-follow sections that include instructions, advice, and helpful hints. Each one begins with a photo and/or video, a short introduction, and a list of materials. Other sections include assembly instructions, how to use the activity, and explain what’s going on, science-wise. Most Science Snacks can be built by one person; we indicate if a partner or adult help is needed. A section called “Going Further” offers interesting bits of additional scientific and historic information.” (Science Snacks /About)

A great number of these activities are simply fun, children would have a great time experimenting with them. See, for example the Bee Hummer which children spin round to make it sound like a swarm of bees.  It starts with a list of resources needed, instructions about how to make it, and goes on the explain what is happening in easy language:

“When you spin your Bee Hummer, moving air makes the rubber band vibrate. The air flowing over the rubber band makes it vibrate the same way that wind blowing over a flag makes it wave. Sound is produced by those vibrations, in the same way that vibrating strings on a guitar or violin produce sound. The index card amplifies the sound. If your Bee Hummer doesn’t seem to be working, check to be sure that the rubber band isn’t twisted, and that the string isn’t touching the rubber band. Either of these things could stop the sound.”(Science Snacks)

The Science Snacks are alphabetically listed so you can either search, or look through them to find useful experiments.
