Essential Understanding

The student knows that energy, force, and motion are related and are a part of their everyday life.

Science Background

Teaching About Magnetism: Lab for Extraterrestrial Physics, NASA (website) - Transcribed presentation on the basics of magnetism by David P. Stern, Emeritus at NASA’s Goddard Space Flight Center.

Assessment Ideas

Give each student a bag containing four metal objects that are attracted to a magnet and four non-metallic objects that are not attracted to a magnet. Ask students to predict if each object will be attracted to a magnet, and to record their predictions. Then, give all students a magnet. Have them test their predictions and record the outcomes of their investigation.

(K.2B) Plan and Conduct Descriptive Investigations
The student is expected to plan and conduct simple descriptive investigations such as ways objects move.

(K.2C) Collect Data
The student is expected to collect data and make observations using simple equipment such as hand lenses, primary balances, and non-standard measurement tools.

(K.2D) Record and Organize Data & Observations
The student is expected to record and organize data and observations using pictures, numbers, and words.

The student is expected to communicate observations with others about simple descriptive investigations.

(K.4A) Tools for Collecting Information
The student is expected to collect information using tools, including computers, hand lenses, primary balances, cups, bowls, magnets, collecting nets, and notebooks; timing devices, including clocks and timers; non-standard measuring items such as paper clips and clothespins; weather instruments such as demonstration thermometers and wind socks; and materials to support observations of habitats of organisms such as terrariums and aquariums.

(K.4B) Five Senses
The student is expected to use senses as a tool of observation to identify properties and patterns of organisms, objects, and events in the environment.
