The purpose of this investigation is to understand the change that takes place when water condenses from a gas to a liquid, and how a change in pressure affects this transformation. Materials needed for the experiment include a large (2L) soda... (View More)

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)

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 activity builds the basic understanding that the heating (indicated by temperature differences) of an object is related to the object’s surface color. Materials required for this investigation include a pair of thermometers, light and dark... (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)

This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic... (View More)

This is an activity about electromagnetism. Learners will set up a simple circuit using a battery, wire, and knife switch, and then use a compass to map the magnetic field lines surrounding the wire. Next, they will add a coil of wire to the simple... (View More)

This is an activity about electromagnetism. Learners will use a compass to map the magnetic field lines surrounding a coil of wire that is connected to a battery. This activity requires a large coil or spool of wire, a source of electricity such as... (View More)

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)

In this introductory classroom activity, students exercise their scientific skills of observation and deduction as they use their senses and simple laboratory assays, such as pH indicator paper, to identify mystery pollutants in water samples.... (View More)
