Conclusion

Review your data to see if your hypothesis was correct

A scientist hypothesised that 'the hotter the temperature of a room, the more quickly students fall asleep.' She decided to test this. She set the temperature at 18 degrees and timed how long it took for students to fall asleep. She did these three more times, increasing the temperature by 2 degrees each time. To make it fair, each time there were the same number of students in the room and the teacher told each group the same thing. In the end, her hypothesis was correct

Experiment

Question: Do students fall asleep more quickly if the temperature of a room is hotter?

Independent Variable

The temperature of the room.

Why?

She had control over this variable and changed it which affected the dependent variable

Dependent Variable

The time it took for students to fall asleep

Why?

This variable was affected each time she changed the independent variable

Fixed Variable

Number of students and what the teacher said to them.

Why?

She kept these variables the same to make the experiment fair and accurate.
