Building Materials

Dear Parents,

Our classes will be building our prototypes as we continue to explore the question "How can we as environmentalists design a simple machine prototype that helps the earth?". 

We would be very appreciative if you could send any of the below items to our class:

-Cardboard boxes 
-pop cans
-lids (water bottle lids, jar lids etc)
-old lego wheels that you don't need
-styrofoam
-clear plastic water bottles

Thank you for your support.

Sincerely,

Ms. Kumar and Students of Room 4B
