That's Just Plain Nuts! PDF

Thu, 25 May 2017 17:26:21 +0000

A cool optical illusion and introduction to magnetic induction. You are going to suspend a stack of hex nuts using a pair of book magnets, demonstrating that magnetic fields can be induced in iron objects. To do this you have to set up an arrangement where the magnetic field of the book m..

Levitating Magnets PDF

Thu, 25 May 2017 17:23:04 +0000

The kids are going to use ring magnets on a straw to demonstrate the attraction and repulsion of magnetic poles to one another. They will also measure the effect of weight on the ability of a magnetic field to repel an object.

Take an ordinary iron nail, wrap it with several loops of insulated copper wire, and hook a battery to it. You now have an electromagnet—a magnet that is created when electricity flows through a wire around an iron core. By using a compass and a switch you will be able to demonstrat..

Magnetic Fields Revealed PDF

Thu, 25 May 2017 17:04:40 +0000

Gives the students an opportunity to "see" the entire magnetic field, all at one time, using iron filings. The iron filings are influenced by the magnetic lines of force and align with them in the magnetic field. Sprinkle the filings, like salt, over the surface of a plastic sheet. When y..

Finding Ferrous Materials PDF

Thu, 25 May 2017 10:33:43 +0000

Illustrates that objects that contain iron respond to permanent magnets. The kids will explore the idea that a compass can be used to detect the presence of iron in a material, and then go on a scavenger hunt in search of ferrous materials. A basic chemistry and physics lab.

What is Magnetic? PDF

Mon, 01 Aug 2016 17:08:22 +0000

The kids will test a variety of materials to see if they are attracted to a permanent magnet. This will also double as a classification of matter lab as they test and sort materials by the ability to interact with a magnet. The fun part is when the kids get the opportunity to personalize their ..

Magnetic Fingers & Mini Submarines PDF

Mon, 01 Aug 2016 17:08:21 +0000

One of the funniest demonstrations to present to kids. You will create the illusion that the blood (containing iron) in a human finger has been magnetized. This magnetized finger has the ability to attract an eyedropper that is made of rubber and glass. The point is to introduce the scientific ..

Ferrofluid Fuzz Piles PDF

Mon, 01 Aug 2016 17:08:19 +0000

A ferrofluid, or liquid magnet, is a colloidal mixture of magnetic particles in a liquid. When no magnetic field is present, the fluid is not magnetic and the orientation of the magnetic particles is random. When an external magnetic field is applied, the magnetic particles align with the magne..

Compass in a Cup PDF

Mon, 01 Aug 2016 17:08:18 +0000

Turn an ordinary drinking cup into a compass. It will detect and display the presence of the magnetic field that surrounds the earth. Sounds mystical, but it isn't. Don't throw out your GPS.

Find the Mat..

Electrical Conductivity Tester PDF

Mon, 01 Aug 2016 17:08:18 +0000

Conductors allow the free flow of electrons, while insulators do not. This lab will give the kids an opportunity to build a circuit that allows them to sort materials as conductors or insulators. To do this, the kids will use a D cell battery in a clip, 3 test leads and a 1.5 volt light in a so..
