Flymo Hover Lawnmower

Description:  The Flymo hover mower is built on the same principles as a hovercraft. It contains a fan above the cutting blade that generates lift. This could be used as a phenomenon to explore balanced forces and gravity.

Raw or Boiled Egg Experiment

Description:  This is a simple experiment to demonstrate the idea of inertia. Students could be given eggs that are both raw and boiled and they could use evidence to support the identity of the labeled eggs. In the raw egg the yolk and fluid act as independent objects and so they will continue moving when the egg is briefly stopped.

An egg experiment was necessary in our home this weekend. We were preparing for some serious egg decorating but lost track of which bowls contained raw egg or boiled egg. Without having to crack an egg, we used egg physics to help us solve our problem.

A Bed of Nails

Description:  Special caution should be taken when sitting down or getting up from a bed of nails. In this video, Steve Spangler used a motor to lift the entire bed of nails up and down safely. Each of the nails is pushing on the participant but since there are so many nails the force is distributed safely between all of the nails. This demonstration could be used in any physics unit discussing forces and pressure.

Ellen loves learning cool science tricks from Steve Spangler. When he asked her to lie on a bed of nails, she wasn't so sure it was a good idea!

Amazing Rube Goldberg Machines

Description:  Rube Goldberg machines are named after American cartoonist Rube Goldberg who drew complicated steps involved in doing a fairly simple task (like pouring milk in a glass). Students can study these machines, or build their own, to show how energy can be converted through a series of interactions. In lower elementary classes they might be shown or built to show how pushes or pulls can change the motion of objects. As they move through school they should start to identify specific collisions, interactions, and conversions of energy.

http://www.2dhouse.com/rubegoldbergmachines.php - This was a fun short Rube Goldberg Machine we produced in house. Mostly an experiment but definitely quite interesting and very rewarding to create. We hope you enjoy :).

Amazing Slinky Tricks

Description:  The Slinky was invented by Richard James, an engineer, who was working with springs to support and stabilize equipment on a ship. Simple slinky tricks show how forces (pushes and pulls) change the direction of an object. Students can design a set of stairs, or obstacles, that the Slinky can navigate. In the secondary science classroom it can be used to investigate inertia, oscillations, and Hooke's law. This phenomenon can also be used to investigate wave properties.

Programmable Magnets

Description:  Programmable magnets are engineered to have multiple magnetic regions. This allows engineers to build magnets that concentrate force, align spatially, or both attract and repel. Students can design simple solutions to human problems that use this cutting-edge technology.

Web Resource:  Programmable Magnets - Wikipedia

While at Capital Factory in Austin, we got a demo from Correlated Magnetics Research VP Stephen Straus. Currently operating under various grants and military contracts, they are looking to reach out to third parties to license their technology for use across the globe.

Coupled Pendulum

Description:  The coupled pendulum can be created with either string or a spring connecting the two pendulums. With each swing energy is transferred from one pendulum to the other. If the pendulums both have the same length one pendulum comes to a complete stop before alternating motion. This phenomenon can be used to show balanced and unbalanced forces, how motion can be used to predict future motion, and the conservation of energy.

Coupled Oscillators, or pendulums, are demonstrated by Professor Roger Bowley as part of little Easter series. He's using creme eggs, of course. More eggsperiemnts at http://www.sixtysymbols.com/eggs/

The Walking Table

Description:  The walking table uses pushes and pulls to move the table wherever it needs to be. This phenomenon can be used in kindergarten to show the difference between the two main forces (pushes and pulls). In grade three it can be used to illustrate balanced (not walking) forces and unbalanced (walking) forces.

Magnetic Cannon

Description:  The magnetic cannon contains four spaced neodymium magnets in a channel.  Two balls bearings are placed between each ball bearing.  When a new ball bearing is introduced a transfer of energy occurs and the final ball bearing leaves with a higher initial velocity than the first.  This is a great phenomenon for studying transfer of momentum and the energy of an object based on its position within a magnetic field.

Magnetic Cannon Challenge. Paul Andersen from Bozeman science has challenged me when we met about the magnetic cannon, he wants me to figure out the physics behind a toy called the magnetic cannon. I'll post my answer to this challenge next week.
