First we completed a challenge where we had to hit a domino from the bottom of the stack. This demonstrated the law of inertia; An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This meant that the bottom domino moved when we hit it with a ruler, but the other dominoes would not move unless we hit them as well.
We then used our dominoes to make a domino run. We realised that this activity is linked to the law of inertia as well; as soon as the dominoes begin to fall they continue to knock each other over. We tried some different configurations of dominoes and attempted to use some obstacles as well.
We then considered the different forces involved in this activity and we identified one of them as gravity. Our next challenge was to attempt to build the tallest tower that we could with our cups. We started this with our small groups and then realised that we could build an even taller tower if we combined all of our cups.

ReplyDeleteWhat a great way to learn about the theories of physics! I am keen to give the domino stack a go. Were you all successful? Were there certain strategies that worked better than others. I noticed on the video clip that it is a very fast and smooth movement. Your cup tower looks pretty tall - it looks like about 13 layers. What was the highest measurement built? Keep having fun learning and sharing.

WOW that is extremely cool How do you do that!!!!!!!!!!!!!!
