- Space Travel
- Magnetism (we have 2 different ones)
- Dino excavation
I also have these books that always provide fun and easy experiments that tend to keep the kids busy and free from boredom!
ZoomSci. This website features experiments from the PBS show "Zoom," which we loved until they stopped airing it in our area.
It's always handy to keep things easily accessible. I find that I'm constantly raiding our preschool bins, science bins, and arts & crafts bin. Luckily, I tend to keep them well stocked! But having them there avoids a LOT of the "I'm bored" syndrome. Hope you get some good ideas!
