West Virginia State University College of Professional Studies: Department of Education Teacher Candidate Jordan Bailey, Sara Tulley, Morgan Davis, Whitney Vance Date October 26, 2013 School WVSU Lesson Topic Foam Rockets INSTRUCTIONAL OBJECTIVES/ STUDENT OUTCOMES -Students will learn about rocket stability and trajectory with rubber band-powered foam rockets. -Students will understand the relationship between the projected angles of a rocket verses the distance it travels. -Students will be able to properly measure distances and record them accurately WV CSOs M.O.5.1.11 solve real-world problems involving whole numbers, decimals and fractions using multiple strategies and justify the reasonableness by estimation. SC.O.5.2.16 describe how the variables of gravity and friction affect the motion of objects NATIONAL STANDARDS 2.3 Mathematics: Candidates know, understand, and use the major concepts and procedures that define number and operations, algebra, geometry, measurement, and data analysis and probability. In doing so they consistently engage problem solving, reasoning and proof, communication, connections, and representation; MANAGEMENT FRAMEWORK Overall Time 20 minute lesson Time Frame 5 min. assembly of rockets 15 min. launching rockets STRATEGIES Guided instruction along with a hands-on activity. PROCEDURES Introduction/ Lesson Set WVSU students will demonstrate how to construct a foam rocket. To get students excited we will demonstrate how we launch a rocket. Ask students which angle they think the rocket will travel the furthest? Why? Body & Transitions Constructing a Foam Rocket 1. Using scissors, cut one 30-cm length of pipe foam for each team. 2. Cut four equally spaced slits at one end of the tube. The slits should be about 12 cm long. The fins will be mounted through these slits. 3. Cut a 12 cm length of duct tape down the middle to make two pieces. Place one piece over the other, sticky to shiny side, to make the tape double-strong. 4. Slip a rubber band over the tape and press the tape around the nose end of the rocket (opposite the end with the slits). Press the tape tightly and reinforce it with another length of tape wrapped around the tube. 6. Cut fin pairs from the foam food tray or stiff cardboard. Refer to the fin diagram. Both fin pairs should be notched so that they can be slid together as shown in the diagram. Different fin shapes can be used, but they should still “nest” together. 7. Slide the nested fins into the slits cut in the rear end of the rocket. Close off the slits with a piece of duct tape wrapped around the foam tube. The rocket is finished. Procedure Making the Launcher 1. Print the quadrant pattern (page 78) on card stock paper. 2. Cut out the pattern and fold it on the dashed line. 3. Tape the quadrant to the meter stick so that the black dot lies directly over the 60 cm mark on the stick. 4. Press a push tack into the black dot. 5. Tie a string to the push tack and hang a small weight, such as a nut or a washer, on the string. The weight should swing freely. 6. Refer to the diagram to see how the launcher is used. Using the Launcher: Loop the rubber band over the launcher end. Pull on the fin end of the rocket until the nose cone is aligned with the 30 cm mark. Tilt the launcher up at the chosen angle as indicated with the string and weight on the quadrant. Launch the rocket! Once the rockets are assembled the students will take turns launching them down a long hallway. The floor will be marked off in increments of 12 inches (1 foot). After the students record his/her angle on a piece of paper, they may launch their rocket. The student will then walk where the rocket landed and record the distance it traveled on their data sheet. Each student will have time to launch their rocket multiple times. Ask students what would happen if the rocket was launched at a 90 degree angle. Closure Review the data that each student collected. What was the best angle to a launch of rocket for the longest distance traveled? The average should be around 45 degrees. ASSESSMENT: Diagnostic: Students will be asked, “What angle do you think will cause the rocket to go the furthest?” FORMATIVE: Students will be assessed on how well they work together and how well they follow directions. SUMMATIVE: Students will be asked what angle was most successful at launching their rocket the furthest.
