You don't have to be a physicist to explore the
concepts of physics at DuPage Children's Museum (DCM). You just need the right
materials for exploration and discovery! Some concepts of basic physics involve exploring
motion, gravity, friction, and speed while using simple machines such as wheels,
gears, pulleys, inclined planes, wedges, screws, and levers. The exhibits in Make
it Move (MIM) at DCM were developed so that children could explore some
concepts of basic physics while playing with simple machines. As children play
with the exhibits in MIM, they can begin to intuitively understand some
of these concepts and, with the support of their grown-up play partners, learn
the vocabulary to describe them. Take
note of the words in bold below—there are many words that can be used to
describe simple machines and some basic concepts in physics.
Gear Table
Children
can discover that a gear is a wheel with teeth that can interlock and
turn another gear. They may also
notice the ratio between a bigger
and smaller gear.
Cam
Ball Lifter
While
playing at our Cam Ball Lifter, children
may observe cams—wheels or gears with an offset axle
used to make something happen in a specific order. The cam lifts the ball towards the funnel for increasingly great energy in motion for the awaiting ramps.
Ramps
& Rollers
There
are lots of opportunities to discover that ramps
are inclined planes. If a ball is
let go at the top of the slope, the grade of the ramp can help initiate the speed
of the ball. A ramp is a simple machine that does work for us.
When constructing with ramps and rollers, children can get a visual
representation of using force and velocity!
