Title • An investigation into … • An experiment to show …

Key terminology for this investigation English hypothesis independent variable prediction analysis evaluation 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 • • Bunsen burner beaker safety goggles thermometer 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):

Results table • Title … A table to show … Size of ice cube (Independent variable) Time taken to melt (Dependent variable) (List results in ascending order)

Graph/chart to show results 6 5 4 Series 1 3 Series 2 Series 3 2 1 0 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, …
