Q. A company has made a new material called ‘Wellwarm’. They want to use
‘Wellwarm’ to make coats.
(a) A scientist tested ‘Wellwarm’ to see how well it insulated a beaker of hot

water. She tested ‘Wellwarm’ and three other materials as shown below.

She wrapped each beaker in a different material. She recorded the

temperature at the start and 20 minutes later.

(i) What was the independent variable that the scientist changed?

(ii) What was the dependent variable that the scientist measured during the

investigation?

(b) The results of the investigation are shown below.


Science Date:

(i) The scientist said that the ‘Wellwarm’ material is the best insulator.

Which material was ‘Wellwarm’? Use the results to help you.

Tick the correct box.

(ii) Use the evidence in the results table to explain your choice.

(c) The company made a coat from each of the four materials they tested. A

person tested the different coats by wearing each one in a cold room. He

measured the temperature inside each coat for 30 minutes. Write down two

other variables that should be controlled to make this a fair test.

(d) Write down one thing the scientists should do to make sure the person

testing the coats is safe.
