How Science Works Y7

When carrying out an investigation in Science, you only change one thing - this will be what you are wanting to investigate. What do we call this variable?

• Independent Variable

• Dependent Variable

• Control Variable

When carrying out an investigation in Science. You always have to measure something. This could be measuring the time taken or measuring how much gas is released. What do we call the variable that we measure?

• Independent Variable

• Dependent Variable

• Control Variable

In an investigation in Science, there are always somethings that we have to keep the same each time so that our investigation is fair. Which type of variable is this?

• Independent Variable

• Dependent Variable

• Control Variable

Sometimes we get results that don't follow the pattern of the other results. They look like the don't fit. What do we call these results?

• Anomalous result

• Wrong result

• Something went wrong result

• Abstract result

What would the independent variable be in this investigation: 'Does the surface affect the speed that snails can move?' (Hint - the independent variable is what you are changing)

• The surface

• The speed of the snail

• The age of the snail

• The distance the snail is moving

What would the dependent variable be in this investigation: 'Does the surface affect the speed that snails can move?' (Hint - the dependent variable is what you are measuring)

• The surface

• The speed of the snail

• The age of the snail

• The distance the snail is moving

If we are investigating if the temperature of the water affects how long it takes sugar to dissolve, which 2 of the following would we need to keep the same to make it fair? (our control variables)

• The temperature of water

• The amount of sugar

• The amount of water

• The time taken

After you have finished your investigation, you need to write a few sentences stating what your investigation shows. What is this called?

• A prediction

• An evaluation

• A conclusion

• A graph

Before we start our investigation we can make a prediction and back it up with a scientific reason to explain why we think that. What is this called?

• A conclusion

• A thought

• A hypothesis

• A guess

While carrying out our investigation, we record our results...

• in a graph

• in a table

• in our heads

• we don't need to record our results
