Activity: Design your own car!

Did you know you can design and create your own car??

​

  • We will be doing a couple different things with this car.

​

  • You will be able to add different colors and shapes to your car once you build it.

Activity: What we will be doing

We will be designing and creating rubber band cars for the test track (your ruler).

  • Find a flat surface to place your ruler and create a test track
  • We will be measuring how far your car can go with the wheels and designs you chose
  • At the very bottom of the ruler (0 inches), you will pull back your rubber band cars and see how far they traveled to the nearest whole foot

16

What is the nearest whole foot?

The closest ruler length your car got one of the big numbers.

What we will be doing, continued

  • When you launch your car, have an adult time how many seconds it takes to stop.

​

After our break, Mr. Miskell will be on camera building the base car along with you. If you have any questions, type them in the chat!

Look at your Week 1 learning booklet

Take 10 minutes to draw and design your car based on the previous picture.

​

What will you add??

What else is in the kit for Week 1?

You have the option to choose your wheel sizes, you can mix and match!

​

There are two sets of wheels in each kit. One set of the yellow and black wheels have a pin for your rubber band. Make sure your car has one pin in the back (Mr. Miskell will show you what this looks like).

Step 1 cont.:

Glue one gusset so it lines up with the triangle formed by the popsicle sticks

​

Do this on both sides.

Instructions: Building the Rubber Band Car

Step 2:

Glue the smaller straws to the bottom of the car (opposite the wood piece). These will hold your wheels and axles!!

​

Make sure the big wheels can fit if

choose to use them on the back.

25

Step 3:

​

Measure the length of your front axle

(what is holding the wheels together)

​

Cut your straw to this length. Cut a

line down the middle just like

the smaller straws. Glue this to

the bottom.

Attach your wheels and rubber bands!

You choose what wheels you want to use.

​

  • Use tape to reinforce your straws once you have chosen your wheels.
  • To make your pin stronger, wrap that in tape as well. We will demonstrate if needed!

Calculating speed of your vehicle

​

Look at the table in your workbook. Find your speed with this table.

Why does speed matter for land vehicles?

Speed matters because it determines how long it takes to transport people and goods.

How is your rubber band car different from a real car?

  • We can use models (your rubber band car) to represent real cars
    • Other examples include: Model boats, airplanes, houses, rockets
  • Do we build the car or the model first?
