Mr. Gale records the amount of cars that pass the school at 7am, 12pm and 7pm everyday for a week.

He observes that more cars pass in the evening than at any other time of day.

Mr. Quinn wants to check the results. He should do this by...

• recording the cars more often.

• recording other vehicles as well as cars.

• repeating exactly what Mr. Gale did.

• The material of the t-shirt

• The temperature of the environment

• How wet the t-shirt is

Which of these is an example of an observation?

• volume of water drained out

• the type of soil
