newest exhibit, Raise the Roof, presents a fun and fascinating
look at buildings and what makes them stand up as well as what
makes them come down. This highly interactive exhibit, developed
by the Science Museum of Minnesota, will be available to ECHO
guests through May 1, 2011.
Are you fascinated by the science behind demolition? How do
tall buildings get demolished without damaging the buildings
around it? See how large buildings are demolished without even
scratching a window of a building nearby with the Demolition
Down Draft House
Did you ever experience a chilly wind going through your
house when someone opens a door? And when you open a window in
the room down the hall, you'll feel that chill even faster!
Learn how still air insulates and moving air sets a chill with
the Down Draft House. Here you will open and close air
passageways and gain a quick understanding of how important it
is to button up for winter!
Earthquake Shake Table
We are largely protected from earthquakes here in Vermont.
Though they rarely happen, when they do they are usually small
and do little damage. But earthquakes are dangerous and deadly
and can topple all types of buildings. Create an earthquake and
see how much power is needed to topple a building on the
Earthquake Shake Table.
Buildings of all kinds, when clustered together, help to form
a city or town. Architects and engineers often decide where a
town hall will go or a a library. You can re-think and re-model
a community yourself with the fun Magnet City interactive.
Like a Building
Does your voice sound the same in your basement as it does in
your bedroom? What about in the bathroom? What causes it to
sound different? Learn how sound is affected by the size, shape,
and materials of a space, and then try your voice in eight
different sound environments.
Build a Truss
Did you ever wonder how a bridge stays up? Next time you are
on one look at the geometric shapes that the structure creates.
You'll see many triangles and tangents and other basic building
principles at play. Learn about the importance of compression
and tangents in the construction of trusses with the Build a
Perhaps the most dramatic component of the exhibit is the
Dome Structure. With many cranks of the hand, the building walls
slowly come together and the dome connects and voila, a
beautiful dome building is complete! YOU RAISED THE ROOF!
