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

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?

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

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

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

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

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

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

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

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