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?..
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!
See how convex and concave lenses can be combined to magnify far-away objects.
Curriculum topics: Lights, Optics, Refraction, Astronomy
Kit includes: Idea Sheet, 1 plastic pipe cap, 1 convex lens, 1 concave lens, 1 cardboard tube, and 1 insula..
Shake things up with the power of the Sun
Create and decorate a "critter" whose moves are powered by sunlight. To vary the critter's movements, explore making changes to the swinging "proboscis".
