Straw Rockets |

Students
will be able to construct straw rockets and predict how to achieve the
longest flight possible.Learner Outcome: |

Pairs of students
design and build straw rockets, launch with a preset force, measure distance,
record and check.Set up: |

Students can design,
build, and test their own miniature straw rockets. They will conduct experiments
by varying the trajectory angle.Objective: |

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.Materials: |

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.. |

5.10 Use estimation to solve problem and determine reasonableness |

5.14 Use computation , estimation, calculators nd computers to solve application problems |

5.20 Solve problems by using guess and check, make a table, and find a pattern |

5.23 Collect, organize and display, read a nd interpret numerical data, tables, graph |

5.24 Find the Mean of the given set of data |

5.26 Construct and interpret tables to draw reasonable inferences or verify predictions using available technology |

5.29 Compare and measure acute angles using protractor |

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. |
