Investigating the Rate of Reaction.

Introduction:

In this investigation I aim to discover how temperature affects the rate of reaction with a potato. I will be able to do this by placing potato pieces of equal size into test tubes with hydrogen peroxide in. Then I will plot my results onto a graph and work out line of best fit. This will give me the evidence , so I can see what temperature affects the rate of reaction most.


Investigation:

Introduction:

I have conducted this investigation to examine the change of potato ‘chips’ in 3 different temperatures. This will give good help on my Hypothesis. I can alter any variables if any problems occur with the ones I am using example, Potato strip size, amount of hydrogen peroxide, and apparatus used.

Apparatus:

         
             Notes:

  • Test Tube rack so I can watch an keep the experiments steady and safe the results will be more accurate.
  •  The cutting tile prevents the surface from getting damaged and a ruler can be used to cut the potato strips for more accuracy.












Method:

1) Cut out 3 strips of potato (from the same potato to ensure a fair test).

2) Cut the 3 strips to equal length (4cm), and measure and record.

3) Place the 3 test tubes in the ...
