What are the two types of variables stated in a hypothesis?
What is Independent and Dependent.
On a graph where do you place the independent variable?
What is the X axis
What step in the scientific method do you make careful observations and write down what happens?
What is Observation.

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.
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.
