This week, the 3rd graders made their presentations to the mayor of Greentown (me) about what was causing the pollution problems in Greentown and what should be done about it. We learned that pollution can travel from one place to another because of water and wind and that environmental engineers test soil and water samples in order to identify potential problems in the environment. 3b also started to investigate materials that could possibly be used in our oil spill cleanup process.

In 4th grade, we used what we learned about different types of curved moves to work on the obstacle course challenge and the baseball challenge. Some groups realized that a loop block is a great shortcut when we want to repeat the same moves multiple times!
In 5th grade, we had an exciting week of dismantling technology to see what's inside. We realized that many of our gadgets have a circuit board controlling all of the functions. We made a web to show the supporting technology making up our item, and then we chose something from the web to come up with a new invention. We talked about invention by reduction - like how someone took away a wheel from a bicycle to make a unicycle or took away the pedals to make a balance bike.
