Friction Fun! Toy Team Members: Emma Drum, Emma Schooley, Vern Patel, and Raj Patel Team Name: The Amu s ing 4 Team Number: B218-3 Class: EF-152 Spring 2018 Date: April 3rd, 2018
Customer Product Requirements Selection Target Audience: 1st, 2nd, Had to two main ideas first: ● ● and 3rd grade elementary Airplane Toy ○ students. Friction Toy ○ Wanted to focus on a Decided to go with the ● ● younger age group of Friction Toy students 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 others. 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
