exploring drag

Today we started our Aeronautical Engineering unit from the Engineering is Elementary curriculum Designing Parachutes. After reviewing the storybook and completing the worksheets that correspond to the first lesson, we went outside to get some hands-on exploration of drag!

 In addition to our engineering fun, we also learned about George Washington and then the boys had a grand time playing with all of the magnets! There was some serious imaginative awesomeness going on today!

testing bridges

We continue to progress through our Engineering is Elementary: Designing Bridges unit, this time testing out the strength and failure modes of various bridge designs. We tested three different designs, and then improved upon the strongest design to make it even stronger! Our strongest design, using just cardboard bricks as the abutments and card stock as the span, supported over 1 kilogram! Pretty cool.

Here are the three designs we tested:

 It was such a gorgeous day, that after building bridges and learning about Helen Keller, we had to go outside and play!
