Here is a great science craft to teach kids about alternative energy: a solar oven! Harnessing the power of the sun is cool and teaches us about caring for our environment and using renewable resources. Best of all, kids can make a snack they love, nachos, using the solar oven they made using this DIY. The directions are remarkably easy and you might already own all of the materials needed. It's a wonderful summer activity to do with your own kids, or in a community or classroom setting.
Go Green: For this ephemeral nameplate, take a walk with a purpose, collecting such items as leaves, stems, and twigs. Back home, have your child write his name lightly in pencil on sturdy paper. Glue the natural items over the penciled lines.
