This is a lesson about measurement and cratering. Learners will read about the origin of the foot as a standardized unit of measure, work collaboratively to conduct an experiment about cratering, and collect and record data to draw logical and... (View More)

Learners will read about Mars and then examine an unknown sample (such as a sandwich or "fun size" chocolate bar) to determine if the sample could have come from Mars. The lesson uses the 5E instructional model and includes: TEKS Details (Texas... (View More)

This is a lesson about the electromagnetic spectrum. Learners begin by arranging a set of picture cards; in the discussion afterwards, this activity is related to the electromagnetic spectrum as an arrangement of energy waves. Next, using a... (View More)

This is an activity about seasons. Learners begin by brainstorming a list of activities and events that occur in each season. Next, learners perform an experiment by comparing the temperature on thermometers left under a lamp for different lengths... (View More)

In this activity, learners construct a classroom-based Space Weather Action Center and use it to obtain, analyze, and record real solar data on a weekly basis. A set of sequential activities are also provided to engage the audience in making... (View More)

This is a hands-on lab activity about evaporation. Learners will conduct experiments to observe the process of evaporation. They will then describe the process of evaporation, and the general water cycle, through discussion and pictures. Background... (View More)

This is a hands-on lab activity about seawater density. After developing a hypothesis, learners will conduct a simple investigation of density. They will discuss changes in density observed and describe how salt affects the density of water.... (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 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)
