This activity has two purposes: challenge the learner to develop a procedure for investigating a research question and to learn more about factors affecting the dynamics of air in motion. It demonstrates that warm air and cold air differ in weight... (View More) and this difference affects air's vertical movement in the atmospheric column. Resources provided to students for this challenge include a homemade balance beam made of wood, two paper bags, a desk lamp, paper clips, tape and a thermometer. The resource includes background information, teaching tips and questions to guide student discussion. This is the chapter 8 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.

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) other end. Resources needed include a piece of wood, two rubber balloons, two large paper clips, ruler, nail, hammer and tape. The resource includes background information, teaching tips and questions to guide student discussion.

In this hands-on activity, students create a model soil profile in a two-liter beverage bottle, time the movement of water through different soils and observe the amount of water held in these soils. They observe the filtering ability of soils by... (View More) noting the clarity of the water before and after it passes through the soil. The activity is supported by a student data sheet. This is a learning activity associated with the GLOBE soil investigations and is supported by the Soils chapter of the GLOBE Teacher's Guide. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)

This learning activity engages students in measurement of pH in water and soil samples, plants and other natural materials. By mixing different substances, they observe how pH changes, and become familiar with the pH of common household products.... (View More) Through discussion, they learn how pH can be modified in the environment. (View Less)

This activity guides students through sampling, identification and counting of macroinvertebrates sampled in a GLOBE hydrology study site, and understand how the taxa composition found in the sample can be an indicator of water quality and ecosystem... (View More) health. The resource includes 8 field and laboratory protocols. This resource is a protocol within the Hydrology chapter of the GLOBE Teacher's Guide. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)

In this 2-part inquiry-based lesson, students conduct a literature search to determine the characteristics of the atmospheres of different planets (Venus, Mercury, Mars and Earth). After collecting and analyzing data, student teams design and... (View More) conduct a controlled physical experiment using a lab apparatus to learn about the interaction of becomes CO², air, and temperature. The resource includes student worksheets, a design proposal, and student questions. Connections to contemporary climate change are addressed. This lesson is the first of four in Topic 4, "How do Atmospheres Affect Planetary Temperatures?" within the resource, Earth Climate Course: What Determines a Planet's Climate? (View Less)

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....
