I like to share high quality, useful teaching tools (that’s why I write so much about the wiki!), and this one is truly impressive. My friend Connor Bernstein sells a range of science kits, including:

• Polymer Power– link polymers, make lots of slime!
• Awesome Insta-pets–Hatch and raise your own brine shrimp!
• Plant Pals–Experiment with plants you can munch on!

Have a look at www.kitsforkids.com – I think you’ll be impressed, and want to try them for yourself or your students!
