Hypothesis: An educated guess about your result before you do it 

most of them are going to be under 1.5 m

Equipment: what you use 

ruler

method: Step by step instructions that you will follow

Discussion/conclusion:

¨talk about¨ the result. how does it relate to your aim 

Evaluate: how could you improve your experiment 

The class found out that the Average height is 158.
