MCC2.MD.1 Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. MCC2.MD.3 Estimate lengths using units of inches, feet, centimeters, and meters. Teacher Notes: Make a variety of common materials available to students. You are not limited to the suggestions in the materials list. Activate students by asking them how objects fly. Point out that some living things fly and others do not. In a similar way, some nonliving things fly and others don’t. Talk about the energy that is required to make a nonliving object. Relate this idea to a slingshot, which makes a pebble or marble fly. What is the source of energy in a slingshot? Ask students for other examples of nonliving, flying objects. In this activity, students are asked to help a Gummy Bear fly. Gummy Bears are nonliving and not designed for flying. However, with the right launcher and a little energy from students, they can do so. When students are brainstorming their designs for a Gummy Bear launcher, tell them that there are some limits or constraints that will guide their work. These constraints are: Only the materials provided by the teacher can be used. (Point out to students that they do not have to use all of the materials.) Time is limited. The teacher will determine how much time students can spend on this activity. In this activity, students are following the design process, although it is not explicitly described. This is the process that engineers use to solve a problem. The steps of the engineering design process are: Discuss the importance of the type of work students will be doing today, which is designing a new piece of technology. Technology can very simply be described as anything that makes life easier or that facilitates a task. For example, the washing machine is technology because it enables users to get their clothes clean with little work. You might want to discuss this with students and ask them what kinds of technology have been developed for these tasks: Need Technology used to meet the need Measuring length Ruler Traveling Car, bus, airplane Carrying books __________ Procedure: 1. Divide students into groups of 3 or 4. Present the challenge to students: A group of Gummy Bears wants to experience the joy of flying, and they need your help. Can you design and build a device that will launch a Gummy Bear into the air so that it flies as far as possible? The team with the Gummy Bear Launcher that send s the gummy bear the farthest is the winner. 2. Ask students to examine the materials available and think about how they could use those materials to make a Gummy Bear Launcher. After students have a few minutes to think, let individuals share their ideas with the group. 3. Let the group discuss the various designs and decide which launcher they want to build. Students should sketch their final design for a launcher in Box A on the Design Sheet. 4. Have one member of the group pick up the materials needed to build this design for a launcher. 5. Let the group build its Gummy Bear Launcher. 6. Once the launcher is built, let students do a trial run to see if it works. Have them launch a gummy bear three times. After each launch, ask students to estimate the distance the gummy bear traveled. 7. Measure the distance the bear traveled. (Optional: Record the measurement in Data Table 1 on the Design Handout.) Compare student estimates to actual measurements. 8. Ask the group if there are any problems with their launcher or improvements they can make. Allow time for students to discuss changes. 9. Let students make the necessary changes to the Gummy Bear Launcher and launch it again for three trials. Have students estimate distances traveled before taking new measurements. 10. Have students sketch their completed launcher on the Design Sheet in Box B on the Design Handout. 11. Discuss with students the differences in their 2-dimensional drawings and their 3-dimensional launchers. 12. Once the launcher is rebuilt, let students do a trial run to see if it works. Have them launch a Gummy Bear three times. After each launch, ask the students to estimate the distance the bear traveled, then measure the distance and compare. (Optional: Record the measurement in Data Table 2 on the Design Handout. 13. Let each team demonstrate their finished project for the class. 14. Have a Gummy Bear Launcher contest and see which bear travels the farthest. Extension: 15. Measure the distance each bear travels during the contest. Collect data on the classroom board. 16. Have students display the data in the bar graph. 17. Have students write a story about a gummy bear who wants to fly.
