Science Granny's Virtual Lab

Crazy Machines is a computer game that requires the player to invent contraptions to complete tasks.  We've included all three versions here, because the version that will be best for your family is the one that runs best on your computer.  These games require a lot of computing power and a good graphic card, so it's worth checking out the requirements before you buy.  Science Granny's granddaughter Cait has had Crazy Machines v 1 for several years and loves it.

Kids put together this robot (it can be made as a climbing or a walking robot, and changing from one to the other is fairly simple).  Although it's described as a gift for ages 10-13, with help younger kids can put it together too.  Science Granny's granddaughter Cait built it with her dad when she was 7.  

Snap Circuits is an easy introduction to electronics.  Diagrams show kids how to snap together the parts to make a variety of electronic devices including a doorbell, a flying saucer, a light with a photocell, a happy birthday song player, etc.  This kit is the 100 version.  There are a variety of versions of this kit, with increased projects at each level.  Fortunately, the company that makes this toy also sells upgrade kits, so if your kid loves it and runs out of projects you can order an upgrade with additional parts and diagrams for more projects.  The parts are easy to work with and each project can be completed in a relatively short time (5-10 minutes), so kids see success immediately.
