In this laboratory activity, students observe what happens when a fluid of one density is placed in a fluid of a different density. The fluids are salt water and fresh water, cold water and warm water. They generalize their results to describe what... (View More)

In this lesson, students construct a rain gauge, collect and graph precipitation data, specifically the amount of rainfall at a locality, then compare their findings with other students' data.The resource includes teaching notes, a vocabulary list... (View More)

Sea floor spreading is demonstrated using a model consisting of two classroom desks and an 8-foot strip of paper. Changes in polarity are indicated using a felt marker. The investigation supports material presented in chapter 3, "What Heats the... (View More)

In this laboratory activity, students investigate chromophoric dissolved organic matter (CDOM) through gradual dilution of black, green and chamomile tea. Through this activity, students discover how CDOM can dominate the absorption of sunlight, how... (View More)

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 is a lesson about the Phoenix Mars Lander's science mission to use robotic technology to uncover water on Mars. Learners will be introduced to the mission and conduct some simple experiments to learn about the important properties of water and... (View More)

In this activity, students work in teams to calculate relative air mass and demonstrate how solar elevation angle affects the intensity of light that reaches an observer on the ground. The resource includes a student data sheet. This learning... (View More)

In this learning activity, students will construct a soda-bottle thermometer, which is similar to the thermometer used by GLOBE schools. Both are based on the principle that most substances expand and contract as their temperature changes. This... (View More)

Students observe cloud type and coverage and weather conditions over a five-day period and correlate these observations. Students make and test predictions using these observations. This is a learning activity associated with the Atmosphere chapter... (View More)

Working in pairs or small groups, students use construction paper to simulate cloud cover. They estimate the percentage of cloud cover represented by torn pieces of paper on a contrasting background and assign a cloud cover classification to the... (View More)
