D is learning about physical science this year and we decided to begin our year with simple machines. He decided to start with some LEGO education building kits, being the LEGO enthusiast that he is. He built a tractor to demonstrate how wheels and axels work, and a crane to learn about pulleys. In our homeschooling group we've been exploring bridge designs and D's class built a truss bridge. At home we've been using the book 'The New Way Things Work' by David Macaulay and Steven Caney's 'The Ultimate Building Book' to read more about simple machines. If you haven't seen either of these books, they are definitely worth checking out of your local library. They are awesome!
