This quantitative experiment involves lab teams in comparing a sample of room air with one of the greenhouse gases - carbon dioxide, nitrous oxide, or methane - and measuring their heat capacity. The activity requires an infrared heat source, such... (View More) as a heat lamp, two 2L beverage bottles, #4 one hole rubber stoppers, and a thermometer or temperature probe, volumetric flasks, a graduated cylinder, and tubing. Nitrous oxide can be obtained from a dentist, methane from gas jets in a chemistry lab, and becomes CO² can be generated using vinegar and baking soda. A worksheet guides student calculations of heat capacity of the different samples. The investigation s is supported by the textbook, Climate Change, part of the Global System Science, an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

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) Background information, common student preconceptions, a glossary and more is included. This activity is part of the Aquarius Hands-on Laboratory Activities. (View Less)
In this lab-based activity, students learn how to use scientific instruments used to take hydrological data. Students will rotate among measurement stations for each of the hydrology protocols that will be done by the class. They will practice using... (View More) the field guide with the instrument or kit for that particular measurement, exploring sources of variation and error. The resource includes eight student activity sheets and an authentic assessment, and is part of the Hydrology chapter of the GLOBE Teacher's Guide. The activity is supported by the GLOBE hydrology protocols. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.

Materials Cost: Over $20 per group of students
This is an activity about lunar and terrestrial stratigraphy. Learners will study the patterns of lava flow by creating eruptions using soda-vinegar solutions and modeling with home-made playdough (stove-top and no-cook recipes are included). This... (View More) activity is in Unit 2 of the Exploring the Moon teacher's guide and is designed for use especially, but not exclusively, with the Lunar Sample Disk program. (View Less)
Materials Cost: $1 - $5 per group of students
Learners will make a model of the Moon's surface and consider the geologic processes and rocks of each area. This activity is in Unit 2 of the Exploring the Moon teachers guide, which is designed for use especially, but not exclusively, with the... (View More) Lunar Sample Disk program. Estimated materials cost does not include cost of binoculars or telescope. (View Less)
