1. oneone IN-1 Objective: To examine a catapult scenario in order to develop a plan for testing distances. Core Question: What factors are involved when developing an investigation? Drill: 1. Get a new paper from the SET. 2. Read the objective. 3. Complete the Drill.

2. oneone IN-1 In your Log Book list 3 things that you now know that will be helpful in the solving of the “Insaner” problem (using a catapult to launch an orb the greatest distance).

3. oneone IN-1 Catapult Simulation: http://www.globalspec.com/trebuchet/

4. oneone IN-1 INSANER Specification Sheet Only the materials listed can be used in the design of the model. The launch arm can be any stiff rod or plane. You may not need all of the materials. The marshmallow (orb) must be launched from a stationary position.

5. oneone IN-1 Remember: Your task is to launch an airtight two- person orb the greatest distance off a catapult into a body of water!!

6. oneone IN-1 Restate the problem question in general terms. How does the design of a catapult affect the distance a projectile is launched?

7. oneone IN-1 Possible Materials: MarshmallowGlue Ruler/Meter StickProtractor Pencil(s)Tape Plastic SpoonJuice Carton Craft SticksBottle caps CupsRubber band(s)

8. oneone IN-1 Think about the materials. How might they be used in the overall design of the catapult?

9. oneone IN-1 Identify what needs to be observed and measured in order to solve the problem. The distance a projectile is launched

10. oneone IN-1 Homework: Draw some possible catapult designs.
