INTRODUCTION

For this year’s FINAL JUNE PRACTICAL LAB, students will be building a

self-propelled race car. Students will design, build, test, and race the car

using simple materials. Students can create and build their car using

whatever creative means they wish but the car may only work using non-

human power (IE. No pushing it).

Students will be graded in five different categories:

- The design (and how closely it matches the end product)(10%)

- The construction

a) in - workshop behaviour (10%)

b) sturdiness of appearance (10%)

- The aesthetic look of the car (Visual appearance) (10%)

- Distance (must travel atleast 1 metre) (30%)

- Completion of a Student Worksheet (30%)

SPECIFICATIONS OF THE CAR

The car MUST have the following parts to it:

- At least 2 wheels (with the necessary Axle assembly)

- A Body

- A Power source

PROCEDURE

STEP 1: Create a BLUE PRINT for your car in your mind

STEP 2: Choose a power source for your car

STEP 3: Design your car and sketch it in the appropriate part of the

Student Worksheet.

STEP 4: Build your car. Taking into consideration some of the

following:

Materials

Newton’s 3rd Law (action – reaction)

Mass

Force

Energy

Friction

STEP 5: Test & retest your car so that it will have an optimal

performance come race day (best distance & straight)

STEP 6: Race it (3 times – Best result)

STEP 7: Complete the Student Worksheet
