State a good hypothesis for this question.
What is...If you increase the amount of milk you drink, then you will increase the strength of your bones.

What is Control.

Thinking about the hypothesis:
If soil temperatures rise, then plant growth will increase.
What might a control in this experiment be?
What is... using the same potting soil, making sure both plants have an equal amount of light etc.

Read the following experiment and state a good hypothesis.
I am doing a test to see if there is a connection between how long you run and how fast your heart beats. I will be performing an experiment where a person will run for a 1 minute and I will check their heartbeat. Then they will run for 2 minutes and I will check their heart rate. I will do this up to 6 minutes and see if there is a connection. What do you think my hypothesis should be?
What is...If I increase the amount of time I run, then my heartbeat will increase.

Find the independent and dependent variables in the following experiment:
If you increase the concentration of phosphorous in the soil of plants, then the growth rate of plants will increase.
What is Independent- concentration of phosphorous, Dependent- growth rate.
