Biology Coursework 2004 Introduction In this project, I will be looking at how long it takes Alginate balls to rise in a test tube of Hydrogen Peroxide and then testing to see if that rate is effected by the concentration of the Hydrogen Peroxide. Variables In this experiment I will be changing the concentration of Hydrogen Peroxide. I measured this variable by first measuring 40ml of Hydrogen Peroxide and then measuring 10ml of Water and adding that to my Hydrogen Peroxide, this was my independent variable. I kept the volume the same by always measuring 50ml before adding it to my test tube. I then dropped the ball in from one thumb space from the top of the test tube. Then as soon as it hit the contents of the test tube, I had some one else time it to make sure that it was fair. I then stopped it as soon...
