Building a Sandbox
Design specifications are online
Putting it all together
Materials that you needSpecial metal parts (e.g.
McMaster-Carrrubber sheeting
You can request small amounts of rubber from professor Cooke at the University of Massachusetts, [email protected]
Aluminum plates
Materials that you need to buy
Wood MDF suggestedGlass windows 1-1/4” screws
For the head screw mount support
A handle for the crank
Putting it all together
MSAD and ISD were able to using their shop facilities
Indiana School for the Deaf students with the shop teacher
Putting it all together
The same students were making the sandboxes in shop class and using in earth system class
Can you build it yourself?
Yes!You need some
carpenter equipment but not specialized power tools Saw Drill Taps for screws Any others Mary?
Mary Ellsworth built one herself
Other things that you need Colored Sand
e.g http://www.dickblick.com/ Fine play sand 3M Duct Tape or Superglue talcum powder Glass cleaner (e.g. Windex) Water repellant for glass (e.g.
Rainex) Duct Tape screwdriver
to remove metal plates Rulers (metal is convenient) Protractors
Exacto knife or scissors to cut the rubber.
flat trowel For spreading the sand into
flat even layers
Flashlight provides low-angle light to
facilitate observing the extensional faults
Problems that have arisen
The sides of the sandbox bow out during the experiment
The moveable wall tilts Can add another anchor
point for bar behind the moveable wall.
Other things that you might want
Latex gloves if using super glue
Disposable Masks Digital camera Tripod for camera
When you assemble a movie from the still images having each image taken from exactly the same spot makes the movie smoother.
Photo manipulation software Lab coats
Your clothes stay clean and you can look professional
Sieve Shaking the colored sand through a
sieve (same size as average sand grain) helps make even layers of colored sand next to the window.
Mylar Slippery mylar along the bottom
of compression experiments 'decouples' the sand from the base of the sandbox. This is one variation of boundary conditions that your students can explore.
Large sheets of sandpaper The high friction of sandpaper
placed underneath the sand can cause higher ratios of wedge height:length than the regular sandbox base.
