PVC Dart Gun Claim-Evidence-Reasoning Lab vA Each group will get the following identical materials (unused materials should be returned): Two balloons Two straws 6” length of PVC pipe Some duct tape as needed Two foam darts The basic instructions for the dart launcher: 1. Cut the straight neck off of the balloon leaving the larger round part. Stretch the round part over one end of your PVC pipe about an inch and secure in place with duct tape. 2. Insert the straw into the end of the foam dart; you can secure with a little bit of duct tape. Don’t use too much or you will impede the dart when it leaves the PVC pipe. 3. To launch, drop the dart with straw down into the pipe. Being sure to aim away from any people or property pull back on the balloon without catching the straw and release. 4. Retrieve your dart for reuse. Pre-Lab: Answered in your notebook How can you consistently launch the dart each time? Be specific! Question: How can we determine how high the dart goes when launched straight up? Procedure: The basics for how to operate the dart launcher are above. You are to write the specific instructions to test your specific question. What will you measure? How many times will you measure it? What tools will you use for measuring it? Write your procedure in your notebook. Data: In your notebook write down any data you collected. Be sure to take at least three trials for each change in measurement. For example, if you launched it at different heights you would launch it from the same height three times, then change the height and launch it from this new height three times. Any necessary calculations should be included here in complete GUESS calculations. Conclusion: 1. Make a Claim that answers the question at the beginning of the lab and can be supported using your results. The Claim should answer the question, “What do you know?” 2. Cite Evidence that supports your claim based on the data you took during the lab. Your evidence should be specific but do not yet explain the next step. The Evidence should answer the question, “How do you know that?” 3. Now, explain your Reasoning, which means explain why the evidence you cited supports your claim (that answers the question). The Reasoning should answer the question, “Why does your Evidence support your Claim?”
