- Students will be shown the instructor’s original “Race Car” Models in Tinkercad.
- The Instructor will explain/show the students what Computer Aided Design (CAD) is.
- Students will create a Tinkercad account at: https://www.tinkercad.com
- The instructor will provide the students with a class Invite Code (Provided to the instructor on their Teach Tab).
- Students will begin to learn how to use Tinkercad by completing a series of tutorials with a partner. Students will show their partners that they completed a tutorial and the partner will initial their partner’s Grade Sheet that they saw it. To access online tutorials, First log on to Tinkercad. Then select the "Learn" tab. Now begin each of the online tutorials - as you watch the video, you should do it! Each time you successfully recreate what is shown in the video, show your partner will initial your gradesheet so that you will get credit.

3D - Racing Cars!
Project Description
“Race Cars” Team Competition (Syllabus and Gradesheet!)
Student teams will design and build a race and compete against the other class teams. There are two titles the teams will be competing for:
Competition #1. Fastest Race Car.
Competition #2. Coolest Car…The Nicest Design.
Tinkercad Training
Developing Your New Skills – “Peg, Cube & Sphere” (40 pts.)
Students will develop their CAD skills by successfully attaching a Cube to a Sphere with a peg. The peg sits in a hole that was formed in both shapes. This skill is the basis for the car that the students will soon create. Grade Sheet
Step-by-Step Video Tutorials:
Competition #1: “Fastest Race Car”
Design – Draw Car to Scale on Draft Paper.
Student Teams will discuss and begin drawing their “Race Car” and then begin the process of drawing it on drafting paper (will be provided to you). Keep the design and development of this car very simple – the goal is for you to build and begin racing a car as soon as possible. There are a few specifications that all “Race Cars” must adhere to:
Specifications: (Maximum Car Dimensions)
Drawing: (View Model Drawing below.)
Your drawing must contain:
CAD (Computer Aided Design) – Construct the “Fastest Race Car” Using Tinkercad
Students must complete their “Race Car” drawing and show it to the instructor prior to building it in Tinkercad.
The instructor will then export and print the pieces of the student’s “Race Car” on a 3d Printer; the student will assemble the car. Student gets full credit when their “Race Car” prints correctly.
Note: Please review the following issues to insure that your “Race Car” will print successfully:
1. Group the body of the car and the cylinder so that the hole will appear and print.
Scoring:
Teams will be placed in brackets of 4 teams. Each bracket will race three times. The teams will be given a score (1-4) following each race. At the end of the five rounds, the scores for each team will be added up and divided by 5. That score will determine placement and grade.Winner = 100 pts.
2nd Place = 95 pts.
3rd Place = 90 pts.
4th Place = 85 pts.
5th Place 80 pts.
All cars are guaranteed at least 80 pts. if they successfully cross the finish line 3 times.
Competition #2: “Coolest Race Car – The Nicest Design.”
Design – Draw Car to Scale on Draft Paper.
The “Coolest Race Car” may not be fast, but will voted on by the class as having the nicest design. Student Teams will discuss and begin drawing their “Cool Car.” Once they have a concept, begin drawing it to scale on the drafting paper that will be provided to you. There are a few specifications that all “Cool Cars” must adhere to:
Specifications:
Maximum Car Dimensions:
Drawing: (View Model Drawing below.)
Your drawing must contain:
CAD (Computer Aided Design) – Construct “Race Car” Using Tinkercad
Students must complete their “Race Car” drawing and show it to the instructor prior to building it in Tinkercad.
Students will build their “Cool Car” using Tinkercad. When they are done, they will submit it to the instructor for review. The instructor will then export and print the pieces of the student’s “Cool Car” on a 3d Printer; the student will assemble the car. Student gets full credit when their “Cool Car” prints correctly.
Although we will will also race these cars, the points will be acquired by the cars design voted on by the class, not the car’s speed.
Scoring:
Winner = 100 pts.
2nd Place = 90 pts.
3rd Place = 80 pts.
4th Place = 70 pts.
5th Place 60 pts.
6th Place = 50 pts.
Understanding Data: Create a Survey / Collect Data / Present Findings With Excel
- The students learned how to collect consistent and accurate data. They agreed on a primary survey and many sub-question to help filter the data. They developed a plan as to how they would collect the data and from whom. They ageed on a format to compile the data. They were taught how to use Excel and present the data using charts. Individually, they anlayzed the data and showed and explained two trends they saw emerging out of the data. Gradesheet: click here.
