Watch this video to learn what the engineering design process is. Use this process to design your first Rube Goldberg Machine in the challenge below! You can also download this Engineering Design Process worksheet to help you remember the steps. It is important not to skip this step. Before building, your team needs to brainstorm several ideas and then select one idea and build a prototype. During the competition at the North Florida Fair, teams will need to show their design to a judge before they begin to build.  As you build and test your prototype, you will need to make adjustments. Keep notes of the adjustments you make on the back of your design so you will be able to talk about them when you present your final design to the judges. 

Juniors (8-10 years)- use at least three different types of simple machines to apply toothpaste to a toothbrush.

Intermediates (11-13 years)- use at least four different types of simple machines to apply toothpaste to a toothbrush.

Seniors (14-18 years)- use at least five different types of simple machines to apply toothpaste to a toothbrush.

Demonstrate your results and explain why you make the design choices you did!  Be sure to include:

• How many simple machines you used

• Which type of simple machines you used

• Any modifications you make

• What you might do differently next time
