#### Transcript of Gravity Powered Car

What was your favorite vehicle when you
were a child?
How was it powered?
What other types of propulsion are there?
Materials
You will work in teams of 3.
You will have a basic kit and as much scrap as you need.
Wood Weight 100g Dowel rod
Cardboard Cotton reel Wheels
Hot glue String.
You will use the PLTs of
Team worker
Independent enquirer
Reflective learner
Forces + Energies
Process
Design
Work together to discuss possible designs. For homework design 3 possible buggies.
As a team select 1 design. Adapt. and draw a final design with measurements and detailed labels.
You must have a clear plan of how you are going to make your product.
What is gravity?
What stops a car moving?
In the video of the gravity powered car, what makes the buggies move?
Gravity Powered Car
You will learn:
•How to draw a 3D design
•To accurately measure and cut materials
•Health and safety rules for cutting wood, drilling and using hot glue
•Forces and energies
Team work WWW EBI
How can gravity be used to make a car go?
Measure twice cut once.
You must build a car /buggy
You must use potential energy
You must race your car and evaluate it's performance.

Have you used any recycled materials?
Have you designed a shell or body for your car?
How could you make this using discarded materials?
HWK
Levels
3
a diagram with naming labels (what)
4
A well drawn diagram using descriptive labeling (what, how)
5 +
A 3d Diagram using descriptive labels. Referring to energy transfers and forces. Describe how you have maximized or minimized key factors.
Research and describe 4 vehicles and their method of propulsion.
3 - images with name label
4 - images with basic labels to describe
5 - images, labels to show energy conversion
Instructions to build a gravity powered car.
Design and create a small booklet that describes to a target market 8-10 year olds -
You must describe with detailed diagrams and written instructions how to construct a gravity powered car.
What makes a gravity buggy successful?

What mistakes will you avoid in your design?

What should you maximise
What should you minimise

What is your method of propulsion?
How will you use the force of gravity?
What impact will inertia have on your buggies success?
Propulsion

Noun

The action of driving or pushing forward.

Gravity

The fundamental force of attraction that all objects with mass have for each other. The fundamental force of attraction that all objects with mass have for each other.

Inertia

The resistance of a body to changes in its momentum. Because of inertia, a body at rest remains at rest, and a body in motion continues moving in a straight line and at a constant speed, unless a force is applied to it.
