1. HAPPY THURSDAY BIO-NINJAS! FOR YOUR BELLWORK TODAY: SET UP PAGE 7 OF YOUR JOURNALS EXACTLY AS YOU SEE IN THE DIAGRAM.

2. Remember Lab Safety Rules! 1. Dress for Lab: aprons, close toed shoes, pull hair back 2. Personal Protective Equipment: Safety Goggles 3. Chemical Safety: Don’t touch anything, assume all materials are dangerous 4. Dispose of messes properly 5. Proper Lab behavior: no horseplay, no eating or drinking in the Lab.

3. LAB CHAMPS C-Conversations are only about the Lab and only within your Lab group H-Follow instructions of the Lab. Ask group members before asking a teacher A-Make observations and work with your Lab partners M-Do not move from your group. P-Work as a team to complete the lab

4. LETS GET STARTED! Make observations of the Lab set up. In the “Hole 1” column Draw a picture of what you see in the Lab set up What do you see?

5. QUESTION Our Lab set up includes a tub and a 2 liter bottle that has three holes covered by black electrical tape. What do you think will happen if we pull the tape back to uncover just the first hole? In the “Hole 1” column write your prediction. Your prediction does not have to be the same as others in your Lab group.

6. HYPOTHESIS: Re-write your prediction in the form of a hypothesis. If _______, then______, because________

7. LET’S TEST YOUR HYPOTHESIS When I give the signal you may SLOWLY and CAREFULLY pull the tape back to uncover only the first hole. I will give another signal for you to cover the hole back up. *Try not to squeeze the bottle during this process!

8. RECORD YOUR OBSERVATIONS In the “Hole 1” column write down what happened in the “observations” section. Try to be as detailed as possible. Write down EXACTLY what you observed.

9. IN THE HOLES 1 AND 2 COLUMN Draw a picture of what you just saw in the “DIAGRAM” section. We will repeat this process for the remaining sections of our Lab Notes. Be sure to listen for my signals.

10. SUMMARIZE YOUR OBSERVATIONS AND GENERATE HIGHER LEVEL QUESTIONS You do not necessarily need to have the correct scientific answer for why this happened but I do expect you to tie this in to the scientific method.

11. BONUS QUESTION: What would happen if we repeated this process but the bottle was held horizontally with the holes pointing down instead of sitting vertically?
