Paper Airplane Lab This lab is set-up to combine your creative skills, while allowing you to be able to modify your technology and witness whether or not these modifications improve performance results or not. You must complete all aspects of the lab, and in the end write up a lab report using the following criteria: 1. Introduction: Why did we do the lab? 2. Problem: What were we trying to determine? 3. Hypothesis: What do you think is going to happen? How do you think the addition of paper clips to the airplane will affect its flight distance? Does the placement of the clips matter? - This must be created before the experiment is completed. - Style it similarly to: If paper clips are added to the (location) of the paper airplane, then _________________ . 4. Predictions: What do you believe will be observed? Will more paperclips on the plane make it fly better or worse? Will the plane fly a longer distance if paper clips are only placed on the front of the plane? Think of these styles of questions. Must be created before the experiment is completed. 5. Materials: What supplies were used during lab? Write in a list format. 6. Procedure: How are we going to perform the experiment? This is a step by step explanation of what you did to perform the experiment. - What do we need to do? What needs to be kept constant? What is our control? What is our independent variable going to be? Where are we going to perform the experiment? 7. Observations: Did the plane fly far? Did it nose-dive when paper clips were added? Did it fly crooked? Record the observations of each trial while completing the lab. 8. Results: Data tables and graphs. Here is where you record the numbers and calculations of what was observed. The time of flight, the distance the plane travelled, etc. Include all necessary labels on graphs and tables. 9. Conclusion: Explain your results in this section. What did you conclude about the amount of paper clips and flight time of the paper airplane? Include any possible mistakes that could have been made (possible sources of error). Was your hypothesis supported (why or why not)? Is there anything you could have done differently? The Procedure: In groups of two, students will create a paper airplane and test whether the addition of paperclips will improve or weaken the flight of the plane. They will create their hypothesis and predictions before the start of the lab. Then they will collect the materials (paper, colour pencils, paper clips, meter stick, etc) and build and decorate their airplane to make it uniquely their own. The class will then head to a designated area where they will fly their airplanes. Each team will have 1 member line up at the "departure" line, and throw their airplane. When one member throws the plane, the other is in charge of timing the flight (record of time will start when team member A releases the plane, and stops when plane "lands" on the ground). Both members will observe the flight of the plane. Once all planes have landed, teams will then measure the distance the plane flew from the departure line. The flights will be completed in 4 sections. Each section will have a modification, and 3 test flights will be done with each modification. First trial: Fly the plane 3 times (trials) with no adaptations Second trial: Fly the plane with a single paper clip somewhere on the plane, e.g. on the back of the plane (complete 3 trials with paperclip in same spot) Third trial: Fly the plane with the single paper clip on a new spot on the plane, e.g. if it was on the back for the second trial, move it to the front (complete 3 trails this way) Fourth trial: Add more paperclips for comparison. (Complete 3 trails with same amount of clips in same spots) Once all flights are recorded, the class will return to the classroom and work on the lab report. Students will complete the calculations (average velocity of each flight), remark on observations, discuss possible sources of error, and create graphs based on their data. Hypothesis and prediction: A copy is due to me on Monday, December 15th This must match the hypothesis and prediction in your lab report! We will fly the airplanes on December 16th Your lab report will be due by the end of the day Friday, December 19th. You can work on this in class on the 19th as well. **Do NOT use pronouns in your lab report! Ie, do not say, “I think that”, “We saw that”. Instead, use phrases such as “It is believed that”, “It was observed that”, “Therefore, it can be concluded that”** Data Section Number of paper clips (indicate position) Trial 1 Trial 1A Trial 1B Trial 1C Trial 2 Trial 2A Trial 2B Trial 2C Trial 3 Trial 3A Trial 3B Trial 3C Trial 4 Trial 4A Trial 4B Trial 4C Calculation area: Observations: Length of flight (Time) Distance Travelled
