Steps to write a car for science

Put a top on the car, add wheels, and set up the antenna. What happens if you try to inflate the balloon even more? Whereas Exposure Value is a base-2 logarithmic scale, the lux scale is linear.

So, whether you measure the balloon when it is inflated or deflated depends on where you place your phone relative to the car when it starts moving. Figure 4 shows an example sketch of a design.

What are some different ways potential energy can be stored? To do this, insert one rubber band half way through the middle of another, and then tuck one side through the center of itself, like this: Insert your rubber band chain through the holes in the bottom of the cups.

You can come up with your own design requirements, but here are some suggestions: The car should be sturdy and not fall apart when in use. Step 8 — Cut Pulley Notch Cut a small notch out of the middle of the box where the axle pulley is located. If your car does not work at all it does not move forward even a little bit, or it falls apart , try to figure out what is wrong. Results The rubber band racer will speed forward. Make a sketch of your design on paper before you start building. Based on what you find in step 6, make changes to the design and construction of your car. Measure the diameter of the wooden skewer or dowel rod you are using as this is the size hole you will need to drill in the center of the pulley. It might help to have a volunteer operate the camera while you operate the car.

Step 6 — Prep The Wheels For the wheels, you can use alot of different recycled items. Poke a hole in the bottle cap and secure the fan to the motor shaft wth glue.

This opening should be around 1 inch wide. An example sketch of a balloon car design. Put the bottoms of the cups together so the holes align. Put the RC car together according to the kit, and document the assembly process.

Apply glue to the end in order to secure the cap to the wooden axle. Mount the motor and battery on the other side of the bottle with glue. On one side, attach a paperclip to the rubber band so it cannot fall back into the cup. Make sure your car can drive directly over the phone so the phone goes between the car's wheels without hitting it or getting stuck.

Once everything is dried, you can snip off the end of the wooden axle with tin snips or something similar. Building Your Car Once you are done designing your car, it is time to start building! Whereas Exposure Value is a base-2 logarithmic scale, the lux scale is linear. This notch will allow the motor pulley to function properly. On the other side, insert the rubber band through the middle of the washer. Documenting your design ideas is important for an engineering project, especially if you are entering a science fair. Related learning resources Science project Rubber Band Heat Engine Kids will create their own version of Richard Feynman's rubber band heat engine to learn about thermodynamics with this cool science fair project idea. Make sure the kit has a decent amount of parts and is something you'll be able to put together on your own. Note that these are also referred to as "milkshake straws" or "smoothie straws. In the app, open the light sensor and press the record button.
