Marble roller coaster science project plan.

The marble roller coaster is an open ended challenge. In addition to the roller coaster materials you ll need a stopwatch and a heavy object. 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 is not easy to get it right the first time.

You can build one just for fun or do this as a science fair project. This homemade roller coaster is definitely one of the most fun science projects but it is also one of the most challenging. Get the science fair guide. A steeper slope will accelerate the marble the faster however the total track length will be longer.

Build a marble roller coaster from foam pipe insulation in this fun science project. You have to experiment with different height and different loop sizes to make a good roller coaster marble run. To build a straight segment. Create the longest track possible without letting the marble fall off.

Before you try building an entire roller coaster practice building the individual track segments. The marble relies on the force of gravity to speed it up as it travels down the track. What type of slope will accelerate the marble the fastest.
