Mass vs. Weight Gizmo & Notes

Today we completed the Mass & Weight Gizmo.  Since we couldn't make it into the computer lab students took turns coming up to my desk to manipulate the gizmo. 

This gizmo is avaliable to them at  They are encouraged to explore it on their own. 

After completing the gizmo as a whole group.  We created a t-chart on the front and wrote down some notes about the difference between mass and weight.

I also shared the following video with them.

Mass & Weight Double Bubble

For homework students were asked to create a double bubble comparing mass and weight. 

This really made them think because we had just watched a video that said Mass & Weight are NOT the same!
