As discussed in class yesterday, there are a number of things you need to bear in mind. These include:
1. What is the variable that you are going to change?
2. What is the variable you are going to measure
- Time for water to enter the soil?
- Time it takes for water to leak out of the soil?
- Amount of water the soil can hold?
3. What variables need to be controlled?
4. What other pieces of information need to be collected and how are you going to present your results?
5. What were the faults in your experiment? Can these be improved?
