2. Task All of you are scientists working in a team of four.
Your team has been tasked to find out whether colours will affect the rate of heat transfer.
You will be given three different colours to conduct an experiment to find out, which colour will absorb the most heat on a sunny day.
The three colours are White, Yellow and Black.
The equipment and items that your team will be receiving are:
1 White-coated,
1 Yellow-coated
1 Black-coated drink can
1 Datalogger
1 iPad
Tap water
Bear in mind, you will need to record the temperature of the water in each cup before the start of 15 min and at the end of 15 min.

3. Experimental Set-up (Part 1)
In the space below, plan, design and draw the experimental set-up.
Important! Is your experimental set-up fair? _______________

4. Experimental Set-up (Part 2)
In the spaces below, state the variables of the set-up.
Variable(s) is / are changed
____________________________________________________________________________________________________________________________________________________________________________________________________________________
Variable(s) is / are kept the same

5. Experimental results Materials White Yellow Black
Temperature at the start of the 15 minutes
Temperature at the end of the 15 minutes
Difference in the temperature (End – Start)
White
Yellow
Black
Based on the above results, arrange the colours according to how well they absorb heat.
From the best absorber of heat to the worst absorber of heat.
__________________, __________________,__________________
Based on the above results, which colour absorbs the most heat on a sunny day. Explain your answer.

6. Discussion
Using the data from the experiment, solve the problem below.
In the year 2500, Earth has ran out of fuel to make vehicles move and to cook the food we eat. The only source of energy is coming from the Sun.
As Earth Scientists, you are to recommend one out of the three colours that you have tested to be painted on a cooker that make use of the heat from the Sun to cook.
Explain why your team recommended the selected colour.
