| Learner Outcome: Students will be able to construct straw rockets and predict how to achieve the longest flight possible. |
| Set up: Pairs of students design and build straw rockets, launch with a preset force, measure distance, record and check. |
| Objective: Students can design, build, and test their own miniature straw rockets. They will conduct experiments by varying the trajectory angle. |
| Materials: Pneumatic LEGO elements or straw rocket launcher (Pitsco-LEGO Dacta.com) 1/4 inch diameter straws, 3/16 inch diameter bendy straws, clay, scissors, clear tape, brown tape, paper, graph paper, pencils, protractors, rulers and yard sticks. |
| 1. Build the launcher following the picture directions. |
| 2. Cut the straw and stop up the end with clay. |
| 3. Test different lengths, weights, and pick the best. |
| 4. Test 90 degrees and describe horizontal displacement. |
| 5-8. Test and record the distance for two trials of 0, 30, 35, and 60 degrees. Estimate , then measure lengths of distance traveled to the nearest 1/8 inch . |
| 9. Average the distance in pair trails. |
| 10. Collect all classroom data |
| 11. Find the Mean (average) by hand and check by calculator, then calculate and record in inches and centimeter. |
| 12. Have two pairs of students input data in Corel Quatro Pro by having one student say and another input data. |
| 13. Calculate means and display data for each trajectory angle. |
| 14. Each student write up their science journals describing building and launching procedure.. |

| 5.36 Estimate and measure lengths of real objects in parts of inch up to 1/8 inch |
| 5.44 Compute and convert customary units of measure within the same system in problem-solving situations. |
| 5.45 Select appropriate tools for measuring to desired degree of precision. |
| 5.50 Use calculator to solve application problems |
| 5.52 Use calculator to find Mean. |
| 5.53 Use a calculator to convert customary units to metric units in problem-soling situation |
| 5.54 Use graphing software to organize and display data by creating table and bar graph. |
| 5.55 Practice inputting data using correct keying, editing and formatting techniques. |
