Lever Experiment

Aim: To investigate the advantage of using a lever to lift a load

Hypothesis: I think the closer it gets to the load the more marbles you will need.

Results: The closer the pivot got to the load the lesser marbles were needed to balance it out.

Explanation: When the lever size changes then the force on the marbles will be greater than the effort applied.

Extracting Water From Coke

Aim: To see how much sugar is in normal/diet coke.


Methods:
-We first set up our equipment

Materials:
-Beaker
-Tube
-Bunsen Burner
-Stand
-Boiling Tube

Results:
On our first try, our experiment overflowed and exploded and landed inside the beaker. This is because we added too much heat and the tube was too close to the bottom of the boiling tube.



On our second try, our experiment had finally work and the water was finally getting separated from the sugary substance. It has worked because we were no longer adding too much heat to the boiling tube and the tube was no longer close to the bottom of the tube.
