This experimental activity is designed to develop an understanding that air has mass. Students conduct an investigation and observe the change in the position of a bar balancing a balloon inflated with air on one end and a uninflated balloon on the... (View More)

In this activity, students monitor the change that takes place when water vapor condenses from a gas to a liquid and see how a change in temperature affects this transformation. Materials needed to conduct the investigation include two thermometers,... (View More)

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

This experimental activity is designed to develop a basic understanding of the relationship between temperature and pressure and that a barometer can be constructed to detect this relationship. Resources needed to build a simple barometer include a... (View More)

This activity promotes student understanding of some of the movements that take place when warmer water and cooler water interface, and how differences in densities, resulting from variations in temperature, set molecules of liquids and gases in... (View More)

This chapter provides a series of investigations, ranging from teacher-centered to open inquiry, that involve the formation of clouds in a model cyclone, and demonstrating how the availability of heat (indicated by temperature) affects formation and... (View More)

This experimental activity is designed to develop basic understanding of the relationship between the angle of light rays and the area over which the light rays are distributed, and the potential to affect changes in the temperature of materials.... (View More)

In this activity, students build a basic understanding of how a sling psychrometer is used to determine relative humidity and learn how to read a chart to determine this relationship. In addition, the student will become familiar with the concept of... (View More)

In this activity, students research scientific discoveries that happened by accident in the past, and learn how gamma-rays were discovered by 20th century scientists. In the process, students develop an understanding that science theories change in... (View More)

This lesson examines the different roles scientists play in discoveries. Students will research various satellites and their uses. In addition, they will explore the different careers associated with the development of satellites, as well as, the... (View More)
