Self-adhesive foam: when the table is fully assembled, the self-adhesive foam attaches to the top board, representing the soil surface underneath your model building.. an inexpensive substitute is florist’s foam. alternately, use a flat baking pan filled with garden soil. (this adds an extra dash of realism to the activity!)
Here’s what you’ll do in this activity. build a shake table—a device engineers use to simulate the back-and-forth shaking of an earthquake. design a building that’s stable and sturdy enough to survive an earthquake. test your building on the shake table and see what happens! 2.
Construct primary shaker tables before the activity. make enough tables for the students to work in groups of 2 or 3. here are directions: how to construct a primary shaker table. the primary shaker table is an inexpensive, but useful tool for demonstrating weak, moderate, and strong earthquake damage to children.
