Presentation by Doug Hansen & Carmelina Coleman

Driving Questions

• Does the North Pole really mean the north pulls?

• Why do farmers have cows eat magnets?

• How do magnets work?

Basic Objectives/Outcomes• Students will learn if the North Pole really means the

north pulls.• Students will learn the purpose of a cow magnet.• Students will learn how to determine the pull of

magnets and which end is really north or south. • Students will use magnets they are given to

experiment and explain how magnets work

Fulfills National Science Education Standard B: • Motions and forces • Light, heat, electricity, and magnetism

Vocabulary to Learn• Magnetorheological (MR) materials are fluids that solidify into a

pasty consistency in the presence of a magnetic field and then re-liquefy when that force is removed.

• Magnetism– The study of magnets and their effects.• Magnetic Field -any region where another magnet would “feel”

a force. • Magnetic Dipole- a pair of electric charges or magnetic poles of

equal magnitude but opposite polarity (opposite electronic charges), separated by some, usually small, distance.

• Electric Charge- a fundamental conserved property of matter. Matter that possesses a charge is influenced by, and produces, electromagnetic fields.

How is this vocabulary learned?

• Students will learn this vocabulary through the hands on experiments with magnets

• Students will also learn them by learning how magnets are used in real life context, for example, the cow magnet.

Why Learn This Vocabulary

• This vocabulary explains why magnets do what they do, so students understand what is happening as they experiment.

Things Available for Purchase

Other Programs Available• Bones, Fossils, and Dinosaurs (classification of

rocks, igneous rocks, sedimentary rocks, metamorphic rocks, identification skills)

• Marbles• Let’s Ponder – Treasure Bag of Thought Provoking

Information• Icy Ice Experiments – Burr to the depth of the read

cold!• Shake, Rattle, and Roll – Seismic waves• Glaciers – What in the life of Wisconsin!• Fossil Mania• Wrap it up – jewelry making

Cost/Chaperones/Transportation

• $200 Dollars for 40 students

• No chaperones needed, however extra help in the classroom might be needed for classroom management.

• Rock and Roll will come to schools at no charge, no transportation needed

Permission Sheet

• No permission sheet needed, students will not be leaving the school.

• No waiver needed.

• After the fieldtrip the students will be put into groups and they will make a presentation using the materials given at the fieldtrip to present a mini-lesson to the class on how magnets work.

• This is important for students because it will reinforce what they learned and it will help to put it into their permanent memory. The strongest form of learning is when you are teaching.

• We would assess the students based on their knowledge of the terms that were covered during the fieldtrip. They will have to present them to the class in their group projects so we will be able to see their general understanding of the concepts.

Literature/Websites"Electricity and Magnetism." By Peter Adamczyk

and Paul-Francis Law.

"What Makes a Magnet?" By Franklyn M. Branley, illustrated by True Kelley.

"Marta's Magnets." By Wendy Pfeffer, illustrated by Gail Piazza.

"Electricity and Magnetism." By Robert Snedden.

Cross-Curricular Connections• For other programs, ex. Fossils program.

This can be connected to art because the student will be able to create their own fossils.

• Shake, rattle and roll can be connected to art and math also because the students must construct their own stolid structure.

Misconceptions

1. All metals are attracted to a magnet. 2. All silver colored items are attracted to a

magnet. 3. All magnets are made of iron. 4. Larger magnets are stronger than smaller

magnets. 5. The magnetic and geographic poles of the earth

are located at the same place. 6. The magnetic pole of the earth in the northern

hemisphere is a north pole, and the pole in the southern hemisphere is a south pole.
