Does a paper clip float or not?.
The things you will need is:
clean dry paper clips
tissue paper
a bowl of water ( We used beakers )
pencil with eraser
tissue paper
a bowl of water ( We used beakers )
pencil with eraser
What we need to do is:
Fill the bowl with water to try to make the paper clip float
Tear a piece of tissue paper about half the size of a dollar bill
Gently drop the tissue flat onto the surface of the water
Gently place a dry paper clip flat onto the tissue (try not to touch the water or the tissue)
Use the eraser at the end of the pencil to carefully poke the tissue (not the paper clip) until the tissue sinks. The tissue will sink and leave the paper clip floating!
It works with a little something scientist call Surface tension. Surface tension basically means there is a sort of skin on the surface of the water. Where the water molecules hold tight together. If the conditions are tight then it will be strong enough to hold the paper clip. The paper clip is not actually floating by it self it is being held up by the surface tension. Many insects such as water strider use this skin to walk across streams.
I think mine will float because it seems easy enough when I saw my classes paper clips float.
Here are some photos of how it went.
With the tissue
Sunken
My experiment was unsuccessful.
I saw every ones else paper clip and it was floating so I thought mine was going to float.
Did you try to make a paper clip float?, you should.
