Science Inquiry Quiz

When investigating whether the size of a container has an effect on how fast the temperature of water inside decreases, choose the most appropriate scientific question.

• What happens to the temperature of the water when we change the size of the container?

• What happens to the size of the container when we change the temperature of the water?

• What happens to the temperature of a plate when we put hot water inside it?

• What happens to a ceramic cup and plate when we place hot water inside?

In this scientific question, what is the independent variable? What happens to the time it takes to run 100 metres when we change the type of shoes?

• The time is takes

• The type of shoes

• The 100 metres

• The runner

In this scientific question, what is the dependent variable? What happens to the time it takes to run 100 metres when we change the type of shoes?

• The runner

• The type of shoes

• The 100 metres

• The time it takes

When investigating whether the size of a container has an effect on how fast the temperature of water decreases, choose ALL the variables that would need to be controlled and keep the same in a fair test.

• What material both the cup and the plate are made of

• The environment, such as sunlight, air temperature etc

• The unit of measurement on the thermometer

• The amount of water in each container

True or False? The independent variable is the ONLY variable that we change in a fair test.

• True

• False

• Not sure

• It depends on the investigation

Materials for an experiment are: 5 different pairs of shoes, a stop watch, a runner, an Olympic 100-metre track. What is the most likely thing they are investigating?

• The effect different types of shoes have on an Olympic track.

• Whether a runner can use a stopwatch correctly.

• How long it takes to run a 100 metres backward.

• The effect different shoes have on the time it takes to run 100 metres.

Looking at the image, choose what is wrong with this graph.

• The person used a line graph instead of a bar graph to show changes over time.

• The person didn't label the minutes on the x axis

• The person chose the wrong increments for the temperature.

• The person didn't include a key to show what the different lines represent.

Choose the BEST scientific explanation for the results shown in the graph of an experiment looking at the effect the shape of a container has on the temperature of the water it holds and how quickly it decreases.

• The plate cooled down quicker.

• The plate's surface is larger allowing more air to flow across the water, cooling it down quicker.

• The temperature of the water in the cup was hotter so it cooled down slower than the plate.

• The surface area of the cup and plate are not important because water naturally cools down anyway.

In an experiment looking at the evaporation of water in the sun, what would be a good prediction?

• The cylinder will evaporate first because its thinnest.

• The dome lid will evaporate the slowest because it has more water than the others.

• The flat lid will evaporate the fastest as more water is exposed to the sun.

Materials for an experiment are: 5 different pairs of shoes, a stop watch, a runner, an Olympic 100-metre track. Choose the best method from the options below.

• 1. Put on one pair of shoes and time how long it takes to run 100 metres.

  2. Change the pair of shoes, and after ten minutes break, time yourself again running 100 metres.

  3. Repeat until all shoes have been tried.

• Firstly put on some shoes and run 100 metres. Have a break and then try it again with different shoes.

• 1. Put on a pair of shoes.

  2. Start stopwatch and run 100 metres.

  3. Repeat.

• Put on shoes and run and time yourself over and over again. Make sure to take note of the time it takes each time.
