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 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)
