Part 2 Now you will put this knowledge to the test: a crash test. You will design and build a "vehicle for your crash test dummy, a raw egg. The goal here is to build your vehicle so that it will protect the egg from breaking, even when dropped from a height of 2 meters. The only materials you can use are: . . a container for the egg (e.g., a small cardboard box or large butter tub) two plastic bags acetic acid (vinegar) sodium bicarbonate (baking soda) tape a graduated cylinder (measuring spoons) a meter stick . Procedure: (Include pictures of the apparatus and the result of the crash) Follow the steps below using the ratio of sodium bicarbonate to acetic acid that inflated the bag, with no acetic acid or sodium bicarbonate left over. (You wouldn't want acid in your air bag, would you?) 1. Inflate one or both bags, whichever you think would work best. 2. Place the inflated bag(s) and the egg in the container. 3. Drop from 2 meters. 4. Check your passenger. Did it survive the crash? Analysis and Conclusions: 1. How much sodium bicarbonate had been added when there appeared to be no acetic acid or sodium bicarbonate left after the reaction? 2. Did this amount of sodium bicarbonate (when there was no acetic acid or sodium bicarbonate left) inflate the bag fully? If not, how could you change the amounts of sodium bicarbonate and acetic acid so that the bag is full, but with no reactants left over? 3. What are reactants? Use question #2 to help you form a definition for reactants. 4. Draw a picture of the vehicle you used. 5. What was the result of your crash test? (Include a picture). 6. What changes would you make to your vehicle to further protect your passenger? 7. How is this experiment similar to an air bag in a car? How is it different? 8. How does figuring out the correct ratio of reactants help manufacturers of real air bags
