Wall Coaster
Marble Run Experiment
Introduction:
| Wall coaster is a fun
educational activity that can also be used for science
experiments related to force, motion and gravity
(physics). Just stick it to the wall and let your imagination soar!
The Wall Coaster uses the basic laws of physics and
gravity to enable hours of fun and imaginative play. The
Wall Coaster comes standard with over 16 feet of track!
Plus, it is super easy to use. Recommended for ages 5 to
adult.
There is NO assembly required. Simply take out the track
and tubes from the package and affix two small pieces of
coaster tack (similar to standard reusable poster putty)
to the back of the desired pieces and push onto the
wall. The coaster tack is created specifically to attach
to walls without leaving any marks. By “trial and error”
you will learn what works and what does not work - this
is part of the fun! |

Use it as a Science Project
To use the wall coaster for
your science fair project, you may mount it on your display
board (made of foam board or corrugated plastic board). The most
common experiment using this kit is:
"How does the
slope affect the speed or a rolling object?"
Project Question: How does the slope affect the speed
or a rolling object?
Sample
Hypothesis: I hypothesize that the speed will
increase when the slope increases.
Display board: Your display will include some low
slope tracks and some high slope tracks. You will show that the
rolling marble moves at a higher speed on the tracks with higher
slope.
Experiment:
1. Assemble and mount three
20-inch long tracks on a wall or display board. Each track must
have a different slope. For example you may try the following
slopes:
- 5% slope (One end of the
track is 1 inche higher)
- 10% slope (One end of the
track is 2 inches higher)
- 15% slope (One end of the
track is 3 inches higher)
2. Place a marble on the upper
end of each track and record the time (Number of seconds) it
takes for the marble to reach to the opposite side.
3. Record your data/ results in
a table like this:
|
Slope |
Travel Time |
| 5% |
|
| 10% |
|
| 15% |
|
4. Use the above data table to
make a bar graph with 3 vertical bars. Name the bars 5%, 10%,
and 15%. The height of each bar will be the number of seconds it
took for the marble to travel the length of the track. (For
example you may make a 5 inch tall vertical bar if it took 5
seconds for the marble to travel the length of the track).
Other possible experiments:
You can also study to see how
does the mass (weight) of a marble affect the speed. In this
case you will need to use marbles made of different materials.
For example a marble made of steel is heavier than a glass
marble with the same size.
Features:
What makes the Wall Coaster
different: All other regular marble runs are built from the
ground up like a building and only include a few feet of track.
The Wall Coaster is different! It is not about the number of
pieces but the length of track. With the Wall Coaster you get
OVER 16 FEET in one kit!
PLUS....
Because of the unique design, you can mount it on a display
board as a part of your science fair project display.
 Each
kit comes with the following parts:
5 - Four inch coaster tracks
15 - Ten inch coaster tracks
4 - Six inch coaster tubes
4 - Coaster retention bands
4 - Specially designed lightweight crystal marbles
1 - Package of reusable non-marking coaster tack
4 - BONUS Glow in the Dark marbles
