Save the Bunny Lab !
Name: ____________________ Date: _________________ Period: __________
Scenario:
Bunnies are going to be used as test drivers in a new type of remote control toy car. Since bunny
seat belts are not available their only protection will be mini air bags. Your task is to use your
commanding knowledge of gases, gas laws, and stoichiometry and determine the correct quantity
of gas to manufacture to adequately inflate the mini air bag. You will use regular household
chemicals such as vinegar (CH3COOH) and baking soda (NaHCO3).
1. Write a balanced chemical equation for the reaction
(Hint: you’ll be making a salt, water and CO 2).
2. Determine the volume of the gas to be used to inflate the bag without popping the bag.
Popping of the bag will kill the bunny.
3. Determine the quantities of each chemical required to produce the amount of gas used to
inflate the bag. ( NOTE: Vinegar is only 5% strength acetic acid )
4. Show the gas laws, data table, and all calculations.
5. 5 Bonus points will be awarded to the team that has the best inflation of the air bag
without popping the bag.
*** No actual bunnies were harmed in this experiment.

LABORATORY WRITE UP INSTRUCTIONS
Number and label each section when writing up the report
Steps 3 – 8 will make this easier to write up. You may discuss these with your lab partners.
1. Names of entire group and the tasks performed by each team member; performed
and due dates.
2. Lab Title
3. Beginning ideas and questions:
List my ideas, questions, concerns, or opinions about this experiment.
4. Tests and Procedures:
What are the tests and exact procedure that I will do to answer my comments in step 3?
above. Bulleted or dashed step by step instructions without pronouns.
5.
Equipment / materials / apparatus
A tabled, bulleted, or dashed list.
6. Observations:
List all relevant observations (gathered by any of your 5 senses) when you performed the
tests and procedures.
You may use graphs, drawings, charts, tables, etc. to explain or show the
observations
7. Claims:
What can you claim happened, or can you identify from your observations. Each claim
must be supported by evidence. (see step 8 below)
8.
Evidence:
What did you use to arrive at your claims?
How do you know the evidence is relevant?
Why are you making these claims?
9. Discussion:
How did your results compare with others?
What did you learn?
What would you do different if you were to perform the experiment again?
