# SC.4.P.8.4

Investigate and describe that magnets can attract magnetic materials and attract and repel other magnets.
General Information
Subject Area: Science
Body of Knowledge: Physical Science
Idea: Level 3: Strategic Thinking & Complex Reasoning
Big Idea: Properties of Matter -

A. All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass.

B. Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or "stuff") in an object. Weight, on the other hand, is the measure of force of attraction (gravitational force) between an object and Earth.

The concepts of mass and weight are complicated and potentially confusing to elementary students. By grades 6-8, students are expected to understand the distinction between mass and weight, and use them appropriately.

Clarification for grades K-2: The use of the more familiar term ‘weight’ instead of the term “mass” is recommended for grades K-2.

Clarification for grades 3-5: In grade 3, introduce the term mass as compared to the term weight. In grade 4, investigate the concept of weight versus mass of objects. In grade 5, discuss why mass (not weight) is used to compare properties of solids, liquids and gases.

## Teaching Ideas

Investigating Magnetism: What are Magnets and Why Do They Attract or Repel?:

This activity is a classroom lab in which students observe and investigate how magnets interact with each other and the objects around them.

Type: Teaching Idea

Exploring Magnetism: Investigating the forces of magnets:

This activity is a classroom and lab investigation of magnetism. Students gather results of experiments involving the forces of magnets. They use this data to develop their own experiments to test properties of magnets.

Type: Teaching Idea

Investigating Magnetic Force Fields:

In this classroom activity, the students will investigate the magnetic pull of a bar magnet at varying distances with the use of paper clips. Students will hypothesize, conduct the experiment, collect the data, and draw conclusions that support their data. Each student will record the experiment and their findings in their science journals. As a class, students will compare each groups' data and their interpretation of the results.
