Friction Fun! Toy

Team Members: Emma Drum, Emma Schooley, Vern Patel, and Raj Patel Team Name: The Amusing 4 Team Number: B218-3 Class: EF-152 Spring 2018 Date: April 3rd, 2018

Customer Requirements

• Target Audience: 1st, 2nd,

and 3rd grade elementary students.

• Wanted to focus on a

younger age group of students

Product Selection

• Had to two main ideas first:

○ Airplane Toy ○ Friction Toy

• Decided to go with the

Friction Toy ○ Has a simpler design ○ Wanted to create further interest in STEM

Conceptual Design

• We basically created a

Free Body Diagram problem in real life

• Initially, we were going to

use an Arduino and a motor to pull the block

• Adding the pulley makes

it easier to pull the block

• Added pegs to change

the angle of the incline

Actual Design

• In the end, we did not use an

Arduino and a motor to pull the block

• A more simplistic approach:

We decided to use different weights to pull the block up the incline

• The pegs and the pulley

remain the same

• Only used 4 materials on the

block, instead of 6

Customer Feedback and Results

• When we were still using the Arduino,

we received feedback that we maybe could move the age range up to 4th and 5th grade elementary students. ○ In the end, we did not use an Arduino, so we kept the age range the same.

• Could market it towards teachers

instead of students when we had to Arduino. ○ Using the Arduino may be too complicated for students

Conclusion

• We wanted to teach the STEM concept of friction

○ Simple and Easy to understand for 1st, 2nd, and 3rd graders

• We wanted students to have fun while learning

STEM concepts

• We wanted to create an innovative way to teach

how different materials cause more friction than

• thers.
• Did not use trial and error.

○ Gave equations and values for them to solve to find how many weights they need to pull the cube
