#### Transcript of Lesson 1 & 2 Balloon Powered Car Project

The Scientific Report Balloon Powered Car Project Investigation Question: Hypothesis Diagram and Materials Almost ready to start making!! Preparing Your Investigation Determining the variables: What are the parts of your balloon powered car?
Think about which parts will affect the distance your vehicle will travel or how fast it will go. Draw the Lotus Chart in your science book
on the left hand page. Fill in the blanks. Your investigation question is what you what to find out. Look at your lotus chart.

Pick one part of the car you will change between the first and second models. Think about why you have picked this part to change.

Write your Investigation question. Choose one of the following statements and fill in the blank:

How will changing the _____________ effect the distance travelled?
OR
How will changing the ____________effect the speed the car travels at between 2 points?

Remember, the goal is to test what effect the change you make will have on the distance it will travel or how fast it goes. The hypothesis is what you predict will happen as a result of the change you plan to make to your design.

For example:

I predict that by(increasing/decreasing) the size of the wheels on the car, it will travel (further/faster) because_______.

Write your hypothesis in your science book on the right hand page.

Remember: use the language of FORCES! Before you start you must have drawn your diagram. Label the diagram 'Prototype 1'

Under the diagram write all the materials that you will be using to construct the car.

List building materials (e.g., 1 balloon, 4 wheels made of plastic milk bottle tops).

List construction materials (e.g., scissors, sticky tape) Before you start:

Safety considerations
Procedure: this is each step you took to build your car. Make sure to jot down brief notes on the left side of your book.
Example:
1. cut cardboard into a rectangle/square/circle for the body
2. sticky taped 2 straws to body, 1 at each end of the car Ready, Set, BUILD!! Fair Testing Record either:
the distance traveled OR
the speed (time) of travel between 2 points. Review: OUR GOALS: 1. Determine what variables the car has.
2. Write your investigating question and hypothesis.
3. Confirm diagram is drawn. List the materials you used.
