Straw Rockets
5th Grade Math, Science, Technology
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 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.
Teacher NoteClear a long area on the floor for landing and measuring.
Set up the launch pad on the floor or a table.  Guide the discovery process, check
to see all students have materials and sufficient access time with the launcher.

Directions: Straw Rocket Lego Piece Straw Rocket Lego Piece
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..
Evaluation:  Students can identify 45 degree launch angle
as giving longer flights than 0, 30, 60 or 90 degrees.
                                  Student's addition and division checks with calculator answers.
Students can show the best outcomes on their graphs.
