Defining a Problem

• To design a catapult to launch a objects

Researching and Generating Ideas

• I will research how much wood to use to exceed the clay balls along the measurements

Identifying Criteria and Specifying Constraints

Exploring Possibilities

• I will explore different possibilities to perfect my catapult.

Selecting an Approach

• I will brainstorm ideas to make an effective catapult.

• I will sketch it first, then succeed in making the catapult.

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.

Making a Model or Prototype

• My model and prototype was the same thing

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.

Refining the Design

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

Creating or Making it

• I made the catapult with wood, some nails, a spring, and a cup.
