What Kids Are Learning
Kids learn about gravity and angles. Depending on the angle of the tracks, which also controls speed, the coin falls down at a certain angle and speed. Kids can build and adjust the placement and angles of the tracks as they test them.

How To Make a Roller Coaster For A Coin
- Fold a paper in half leaving a little space on top.
- Tape the left side of the folded paper so one side is sealed.
STEAM Activity Coin Roller Coaster – Seal The Left Side
STEAM Activity Coin Roller Coaster – Seal The Left Side3. Then tape only the top part of the right side, leaving a hole for a coin to go through.
STEAM Activity Coin Roller Coaster – Tape the Top Right Side
4. make 4 tracks that way.
5. Then do the opposite for the next 3 tracks (right side sealed and only the left top part taped)
STEAM Activity Coin Roller Coaster – Seal The Right Side
STEAM Activity Coin Roller Coaster – Tape the Top Left Side
Now you have total of 7 tracks.
6. Tape them all on the wall to make tracks.
7. Put a coin on the top track and have it roll down!

Note
*Sometimes coin rips the paper a little as it falls if a heavy coin is used. Then you can simply tape the ripped part.
*When multi coins are used, sometimes a few coins may slip out to other side if angle is not steep enough. Then simply adjust angle.
Variations & Challenges
*Kids can make different style of tracks and also routes.
One idea is to use paper towel roll. Ask your child how paper towel rolls can be cut, taped or placed so that a coin or coins can slide down easily.
Here is a paper towel version.
