My first language Aim Consider the following: Why are you doing the experiment? What are you trying to find out? What question are you trying to answer? Variables The variable that I will change is called the independent variable. My independent variable is the (size of the ice cube).
The variable that I will measure is called the dependent variable. My dependent variable is (the length of time taken). I will keep the other variables the same to make sure it is a fair test. The variables that I will keep the same are called the control variables. My control variables are Writing about the effects of variables: o the higher the the faster the o the more the the slower the o the longer the the more the Equipment list

measuring cylinder funnel tripod Hypothesis What do you think will happen and why? E.g. I think that the larger the size of the ice cube, the longer the time it will take to melt. I predict that sugar will dissolve quicker if I stir it because I am providing energy to speed up the chemical reaction.
If I increase the mass of the shoe then the energy taken to pull the shoe down the slope will increase because the shoe will be heavier. Method
First I After that I Next I After several minutes Then I Finally I Safety I had to take the following safety measures (with reasons why): Diagram

Category 1 Category 2 Category 3 Category 4 Analysis My results showed that (comment on the relationship between the variables under consideration).
One result that did not seem to fit was Conclusion The prediction I made at the beginning of the investigation was My results supported/undermined my prediction because Evaluation I made the experiment a fair test by
My investigation produced reliable/unreliable results because Another variable I could test would be If I did the experiment again I would make the measurements more accurate by increase the number of times I did the experiment because take better safety precautions, for example,
