Kids Woot has an awesome environmental science kit priced at only $19.99! This National Geographic Thomas & Kosmos Sustainable Earth Lab normally sells for $44.95, making this a savings of over 50%.
I think this kit would be such an awesome gift for any child that is interested in science, and would be great for home schooling as well. There are over 40 fun and educational experiments including: manufacturing recycled paper and plastic, heat transfer and insulation, and constructing a water treatment facility, just to name a few!
Here are some more details:
The kit is organized into five main sections: renewable energies, natural resource usage, climate change prevention, waste and water management, and energy conservation. Exploring these topics by doing hands-on experiments and seeing real results helps young scientists attain a solid grounding in these often abstract and intangible concepts.
As is normally the case with Kids Woot, shipping is a $5 flat rate for your entire order.
