1. Engineering Design Process Nyla Snowden EF2 2A December 6

2. Defining a Problem To design a catapult to launch a objects

3. Researching and Generating Ideas I will research how much wood to use to exceed the clay balls along the measurements

4. Identifying Criteria and Specifying Constraints

5. Exploring Possibilities I will explore different possibilities to perfect my catapult.

6. Selecting an Approach I will brainstorm ideas to make an effective catapult. I will sketch it first, then succeed in making the catapult.

7. Developing a Design Proposal I will use a specific kind of wood to make the catapult over a weeks time. Afterwards I will add wheels to make the catapult mobile.

8. Making a Model or Prototype My model and prototype was the same thing

9. Testing and Evaluating the Design using Specifications I was told to launch clay balls of 3g, 4g, and 5g to see how long they would go and record my results.

10. Refining the Design I didn’t have to refine my design because my prototype worked the first time with no problem.

11. Creating or Making it I made the catapult with wood, some nails, a spring, and a cup.

12. Communicating Processes and Results
