ShareForce & Motion - Pushing and Pulling
Do you ever feel like pushing somebody?
Let's try a little activity where you actually get to push somebody, but
in return they are going to push on you as well. 
Sit
on the ground or floor back to back with your legs extended in front of
you. Interlock your arms with the person behind you. Now push the ground
with your feet like you are back in a corner and try to get up. Your friend
will do the same to you. You will be pushing each another off of the ground
without using your arms. You must both be pushing at the same time in
order for this to work. How fast can you get up? Try doing this activity
slowly. Which was easier, when you tried to get up fast or slow? Why do
you think the outcome was this way?
How strong are you? 
Can
you pull another person hard enough to get them off balance? I think you
know what to do. Get a rope! You are going to play TUG OF WAR! Try playing
with just one other person and then find a few others to play with you.
See who has more pull. Do you think a person's height would make a difference
in pulling somebody off balance? Play around with the rope. Would a shorter
rope have a different outcome than a longer rope?
Now, are you tired of pushing and pulling? 
Grab
a chair. Make sure it's sturdy. You will be using it, but don't sit down
yet. We're still working here! We are going to push and pull a little
bit more. Put your hands on the back of the chair. Push the chair away
from you. Keep it at arms length. Now pull it back towards you. Push the
chair with a little more force this time, but let go. Did your chair go
very far? Pull the chair back towards you. Which activity is more difficult
(pushing or pulling?) See if you can find a friend to do the same activity.
Who is more successful in pushing? Are you tired now? You are getting
a bit of a workout so I guess you can pull the chair towards you and now
you may sit.
