Identify the two parts.
Marble roller coaster materials.
You can build your own mini marble roller coaster using simple materials like popsicle sticks aluminum foil and a styrofoam base.
You may only use the materials provided.
The roller coaster is a great demonstration of the law of conservation of energy.
Your marble must not fall off until it gets to the end of the track.
The marble must land in the cup at the end of the run.
In addition to the roller coaster materials you ll need a stopwatch and a heavy object.
You may only use the materials provided exception.
Keep an eye on the tinkercad blog and our social media channels twitter facebook for more step by step guides design challenges and other inspiration.
Your marble must not fall off until it gets to the end of the track.
When the marble rolls down the track the potential energy is transformed into kinetic energy.
Your marble must land in the cup at the end of the run.
Real roller coasters use a motor to pull cars up a hill at the beginning of the ride.
Here are some guidelines for building your marble roller coaster.
A marble at the top of the track has potential energy.
You may test your design as you go.
The lesson plan difficulty.
The marble relies on the force of gravity to speed it up as it travels down the track.
A roller coaster demonstrates kinetic energy and potential energy.
If you ve ever been on a roller coaster you know how fun and exciting they are.
If you need to you may tape your roller coaster to furniture.
What type of slope will accelerate the marble the fastest.
Foam pipe insulation 1 5 inches in diameter at least 6 feet in length or more if you would like to eventually add more features to your roller coaster at least one glass marble.
A steeper slope will accelerate the marble the faster however the total track length will be longer.
You ll build a roller coaster track for marbles using foam pipe insulation and masking tape and see how much of an initial drop is required to get the marble to loop the loop it s a great way to learn about how stored energy potential energy is converted into the energy of motion kinetic energy.
Arrange plenty of space in your room cleanup.
Build a roller coaster with 2 hills and one loop.
When you raise the marble you are working against the force of gravity giving the marble potential energy.
Then have everyone gently take apart only their own roller coaster and clump all the used tape into a giant tape ball start of class lecture.
In an isolated system such as the roller coaster the total energy remains constant.
You may tape your run to furniture.
Allow 2 minutes near end of class for students to try each others coasters.
