You want to figure out the volume of Patrick from Spongebob.
Describe how you would accomplish this.
You would use water displacement method - Measure a set amount of water using direct measurement, record the volume, then submerge Patrick into the water and record the new line of measurement on the instrument.
Once you have the two measurements you would subtract them to find Patrick's volume.

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.
