do we need one?

i can't exactly remember the criteria for this blog marking; all i can remember is the climate graph and method, and i just realised that i forgot to include my dependent and independent variables, i'll just write them here, in case they are needed

independent variables:
- the amount of liquid watered to the plants
- the type of liquid watererd to the plants
- the type of soil the plant is placed in
- the type of pot the plant is placed in
- the type of fertiliser used

dependent variables:
- the growth rate of the plant
- the weather
- the original size of the plant
