Inquiry continues in science as the students in room 12 and room 14 added wheels to their catapults.

Some students put the axle through the box. 

 Stability was the most important factor when trying to add a working wheel, and we had to use our experiments to find out how to use the axle and the wheel.

Some attempts were made with attaching the axle to the bottom of the box.

Wheel size and shape were very important in creating smooth movement.

This led to a discussion about how to use a gear, and how gears make work easier.  Pulleys and gears together can create new ways to do work with less effort being used.




We continue to explore simple machines and understand how we can solve environmental and personal problems using simple machines and devices that move.
