1. Investigation: Evaporation
We are going to plan an investigation to test different circumstances to aid evaporation

2. Planning Good planning is essential We must plan our investigation
We need to know what information we want to find out and collect
We must decide what will we observe or measure
We need to list the equipment (apparatus) we will use
Are there any dangers involved?

3. What is our key question?
How can we make water evaporate faster?

4. How can we conduct our investigation?
Put water in different places around the classroom e.g. window, cupboard, radiator…

5. Investigation Make sure it’s a fair test
Gather information and measurements accurately
Repeat our observations and measurements to make sure it’s correct
Record our results with care

6. How can we make this a fair test?
Measure the water
Take accurate measurements at the same time

7. Measuring jug x3 100ml water x3
What do we need?
Measuring jug x3
100ml water x3

8. Amount of water Measuring jugs
What stays the same?
Amount of water
Measuring jugs

9. What do we have to change? (variables)
Location of the measuring jugs

10. Today's task Plan your investigation on your worksheet
Make your prediction – Which location do you think will speed up evaporation?
