Experiment: Do simple machines really make our lives easier?
First AJ tries to pull nail out with his hands
Then IC takes his turn
Finally RW tries.
None of the boys could take the nail out of the wood with their hands.
Finally RW uses a simple machine, called a hammer, to try to get the nail out of the wood.
RW got the nail out!
Next, IC tried with the hammer. He got his nail out too!
Even AJ could get the nail out of the wood with the simple machine.
Conclusion: Simple machines DO make our lives easier.
