Teacher Notes:
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 fly. Relate this idea to a slingshotwhich can make 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 Bearfly. 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 limits or constraints that will guide their work. These constraints are:
Only the materials provided by the teacher can be used. (Point out that students 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.
The Gummy Bear must be launched using the device that students create. It cannot be thrown.
The Gummy Bear launcher must hold two Gummy Bears.
In this activity, students are following the engineering design process. Research can be a part of this process and usually occurs before students start generating ideas. If you have an extra day, you could let students see how other launchers are built.
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:
Measuring length
Traveling
Carrying books
To extend math skills, have students record their measurements to the exact centimeter, then convert the answers to meters, which requires the use of decimals.
Gummy Bear Launcher
Procedure:
1. Your challenge:
Two best-friend Gummy Bears want to experience the joy of flying together, and they need your help. Can you design and build a device that will launch two Gummy Bears into the air so that they flyas far as possible? The team with the Gummy Bear Launcher that sends the gummy bear friends farthest is the winner.
2. You will follow the engineering design process to make this launcher. The steps of the process are:
To begin, state the problem to be solved on your Design Handout. The problem statement might be something like:
We are going to design a ______that will ______.
3. Individually, examine the materials available and think about how you could use those materials to make a Gummy Bear Launcher. (You are not required to use all of the materials.)
4. Share your design ideas with the group.
5. Using everyone’s ideas, determine the best way to build the launcher. Sketch the design plan on the Design Handout and list the materials you need. Have your teacher check your plans and materials list. You must get the teacher’s signature before you can go to the next step.
6. Send one member of the group pick up the materials needed to build your Gummy Bear Launcher.
7. Build the Gummy Bear Launcher.
8. Once the launcher is built, conduct a trial run to see if it works. Launch two Gummy Bear three times. After each launch, estimate the distance the Gummy Bear traveled and record your estimation in Data Table 1 on the Design Handout.
9. Measure the distance the bear traveled and record the measurement in Data Table1 on the Design Handout.
10. Evaluate the launcher to determine if there are any problems to be fixed or improvements to be made. If so, make a list of the necessary changes on the Design Handout, then make the changes to the launcher.
11. Retest the Gummy Bear Launcher again for three trials. Estimate and record distances traveled before taking new measurements and recording them in Data Table 2.
12. Present your finished launcher to the class.
13. Have a Gummy Bear Launcher contest and see which best-friend bears travel the farthest.
Extension:
14. Collect data during the contest on the classroom board.
15. Display the data in the bar graph.
