This is a lesson about the magnetic field of a bar magnet. The lesson begins with an introductory discussion with learners about magnetism to draw out any misconceptions that may be in their minds. Then, learners freely experiment with bar magnets... (View More)

Audience: Middle school

This is a lesson about states of matter and their relationship to temperature. Learners will explore the conditions required for water to be in a liquid state. They discover that temperature is the essential variable. They then explore how... (View More)

Audience: Middle school

This is an activity about magnets and magnetism. Learners first make predictions about magnets, such as a list of the types of materials a magnet will pick up, how a magnet can be made, and how a compass can be made. Next, learners test their... (View More)

This is a lesson about states of matter. Learners will explore the conditions required for water to be in a liquid state. They discover that temperature is the essential variable. They then explore how temperature affects the motion of molecules and... (View More)

Audience: Middle school

This is a lesson to demonstrate magnetic field lines in 2- and 3-dimensions. In the first activity, learners sprinkle iron filings over a magnet underneath a paper and record their observations. The second activity involves building a 3-D magnetic... (View More)

Audience: Middle school
Materials Cost: $1 - $5 per group of students

This is a lesson about the particulate nature of matter. Learners will use their bodies to model the connections between molecules in the three states of matter. They then create a poster that illustrates and explains these connections. The lesson... (View More)

Audience: Middle school

This is a lesson about measuring temperature. Learners will apply their knowledge of how temperature affects matter to understand how a thermometer works. They then read about the history of the thermometer and the temperature scales that make the... (View More)

Audience: Middle school

This is a lesson about phase changes. Learners will observe ice melting and freezing under a variety of conditions and relate that to the Messenger mission. This is lesson 1 of 12 in Exploring Ice in the Solar System.

Audience: Pre-kindergarten, Elementary school
Materials Cost: Free

Learners will use the inquiry process to explore the affect of atmosphere on the temperature of a planet. They create a model of the system to test. They then create a concept map of the planetary temperature system. The lesson models scientific... (View More)

Audience: Middle school

This is an activity about mapping magnetic fields. Learners use a test magnet to create a map of the magnetic field region around a bar magnet. A Magnaprobe, or other similar test magnet, is required to do this activity. This is the third activity... (View More)
