Students discuss their perceptions of magnetism and explore the background ideas of magnetism.

Fourth graders predict, observe, and compare what happens when a force is applied to an object. In this forces lesson, 4th graders complete a 'swinging hammer' activity to learn about forces and motion.

High schoolers construct a sling psychrometer and they measure the relative amount of humidity in the air. They create their own experiment on how to construct a sling psychrometer and how they are going to measure the relative humidity...

Learners work in a group to create a skit of a scenario involving recycling. Student skits should encourage and convince the audience members to participate in recycling activities. Students provide written responses after the final...

Students study the characteristics of magnets including polarity, and the concepts of attraction and repulsion. They examine how magnets are used industry.

Middle schoolers realize that density exists. They develop a mental model of density-to realize that something is going on that they cannot see to account for differences between materials.

Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...

Students are introduced to the ways in which they can make their workplace a safer environment. Using an example of an emergency plan, they follow it in chronological order and identify any hazardous materials. They also comply with...

Learners investigate the properties of water. In this states of water activity, students explore how water goes from liquid to solid and back to liquid again. Learners use measurement, observation, and communication to describe the change.

Students identify biodegradable items. In this environmental lesson, students participate in a game of tag. A student's name is called out along with a biodegradable item and the student is tossed a ball.

Students investigate several properties of the given elements and decide whether each element is a metal, non-metal, or a metalloid.

In this lab activity, learners will be asked to observe and then test the physical and chemical properties of several different elements.

The following tutorial explains the three main types of elements, including metals, non-metals and metalloids.
