What can keep a simple structure from collapsing during an earthquake?
How will an earthquake, simulated by shaking, affect a "building" made of linked squares? How can the square "stories" be cross-braced to prevent the "walls" from collapsing? What dangers are there in building above a garage?..
Discover the rainbow of colors in white light!
White light is actually a combination of different colors. This easy-to-build spectroscope allows students to separate the incoming light into its component colors, forming a light spectrum (rainbow). Besides creating interesting color patterns it c..
An uplifting activity based on air pressure!
Use this activity kit to demonstrate the effects of friction and air pressure on motion. Create a simple hovercraft and be amazed at how it gracefully glides along a smooth, flat surface on a thin cushion of air. How long a “flight” is possible? ..
For Testing Structures Built in Earthquake Country
Building in earthquake country can be a tricky business. Architects and engineers run simulations using models and shake tables to test the integrity of buildings and determine necessary reinforcements. In this activity, students use a very simpl..
Explore magnetic attraction and repulsion.
A variety of scientific and gravity "defying" demonstrations can be done by combining pill and ring magnets in unique ways to create a multipurpose demo unit.
Curriculum topics: Magnetism, Symmetry, Conservation of Momentum, Modeling, Problem Solving ..
Make a telescope like the one Galileo designed!
