You know from our last update post that we'd had the LEGOs out to do some attribute sorting and a creative design challenge. Well, we weren't quite ready to put them away so we constructed a little research unit on the history of LEGO. We used the book LEGO Toys by Kris Hirschmann as well as the video below as our primary sources and created research mindmaps.
We then switched gears and focused on another classic toy--the pull back car. In our first lab, we conducted an experiment to see if the distance we pulled them back had a direct relationship with how far they went. Our hypotheses was yes! As a secondary experiment, we also compared the data between the car running on the table vs. carpet.
The next major questions was: Where is the energy coming from to make these simple toy cars move? There was only one way to find out--we dissected them!
The great discovery of our dissection was a very special machine--the spring! So THAT sent us on another research exploration, this time to gather more information about springs.
And springs are where we currently stand. This will lead us into an exploration of potential vs. kinetic energy and to the creation of a very special Thanksgiving-themed project. Stay tuned! : )
