DO NOW
• WRITE YOUR NAME• TAKE OUT HOMEWORK• Write your group member names• Read the background• Read procedure 1
Immediately take paper towel out after 1 min,lay on counter, and immediately measure thedistance the water traveled in centimeters
We are observing the absorption of water
• Trial #1 Results: The paper towel absorbed ______ cm of water.
• Trial #2 Results: The paper towel absorbed ______ cm of water.
Ask Questions• “What would happen to the rate of
water movement if …”
• “Would the water move faster if…”
• “Would the water movement change if…”
Make a Hypothesis for both Questions
• If _______________________ (something that changed), then the rate of water absorption would increase/decrease/stay the same
Design your Experiment
• Choose 1 question to answer.
• Write the question you chose, and a hypothesis (the possible answer) to that question on page 4.
