Children visiting the Grand Rapids Children’s Museum are playing
with a new educational tool designed and constructed by engineering
students from Grand Valley State University.
The project began when Jan Stone, exhibit and community
relations manager for GRCM, approached the School of Engineering last
year seeking assistance in replacing their more than 10-year-old
bubble tower. “We have more than 150,000 visitors each year and most
of them use the bubble tower, so it was time to find a new one,” she
said. “A lot of engineering calculations go into making these devices,
so I contacted Grand Valley.”
In January 2011, engineering professor Wael Mokhtar assigned two
groups of senior students the task of developing the new bubble tower,
which was completed in August.
One requirement for the new bubble tower was to have it be
wheelchair accessible. “This could very well be the first bubble tower
in the nation that is wheelchair accessible; I’ve never seen one
before,” Stone said. “The students had so much knowledge of materials
we didn’t know existed. They knew what they were doing.”
Communicating with Stone and others from the museum in layman
terms then receiving feedback and translating into technical terms was
a challenge for students, explained Mokhtar. “That’s what it is like
in the working world, though, so it was a great opportunity [for the
students] to experience what it’s like to work with a client,” he said.
Stone explained that the bubble tower touches on many subtle,
but important nuances that are important for a child’s development.
“There are pulleys attached, so kids are experiencing how simple
machines operate,” she said. “The bubbles themselves are a simple
chemical solution and you can tell they are experimenting with what
works and what doesn’t work when the bubbles pop.”
