Let there be Legos


A quick post on the Lego Educator Mechanism Set. This was the street sweeper. They had to switch out gears and blades to find which set up worked the best. There was also a safety experiment where the gears were replaced with pulleys.

Simple Machines


We have been enjoying very full and productive school days! Although this leaves very little quality brain juice for the mom at the end of the day, its has been really fun for the boys and I.

We started a Lego Education unit study. I purchased a mechanism set through a group buy and we have been having such a great time with it. The set is made for two students to build separately then when they have their individual element finished they fit them together to complete the device. They are asked to make predictions, measure results, rate accuracy and change the device with different gearing or extensions to find improvements.

Before we got the set, the boys started building models of the basic simple machines to go over the principles. We took some pictures. I am hoping we will have a nice scrapbook when we are all done. This is Leo's class three lever:
