Sink or Float!

    This Experiment is called Sink or Float

     Equipment

     Plastic Container

     Water 2/4

    Table Salt

    Teaspoon

    Eye Dropper

    Clay

1) Fill the container 3/4 full with water

2) Put a small piece of clay around the bottom of the eye dropper.

   DO NOT BLOCK THE OPENING

3) Float the eye dropper in the water

4) Now squeeze the bulb of the dropper to let air out one drop at a time, testing after each drop to                          see if it sinks.

5) Once the dropper sinks, stir in teaspoons of salt into the water one at a time until it floats again.

Record how many tsps of salt it took to make the eye dropper float again.

Hypothesis: I think it will float.

It did not I think this was because of the smaller size of my container

We carried out a science investigation to find out what affect adding salt to water would have on an object that was weighted doing in water.

My Hypothesis: It would definitely float.

The investigation showed initially that adding salt made no difference. After adding and mixing 6 tsps of salt however the eye dropper did not float. Me and my partner altered our eye dropper by taking some clay off but it still did not work.
