This activity is about how fossil fuels release carbon. Learners will use toys, sand and other materials to simulate a city, considering the formation of fossil fuels and how burning these releases carbon and produces warming. As part of the... (View More) discussion, they will review the respiration equation. They will then create a mural illustrating the path of the carbon from dead forest, to fossil fuel, to mine, to power plants, to homes and cars, and finally to the air. This the third of three activities in "The Carbon Cycle and its Role in Climate Change," which is part of Climate Change, Wildlife and Wildlands: A Toolkit for Formal and Informal Educators.

These two hands-on labs are about the role of temperature and salinity in governing the density of seawater, a major factor controlling the ocean's vertical movements and layered circulation. In the first activity students work in groups to... (View More) determine the density of tap water and of tap water with salt, then compare the densities. The second activity investigates the role of temperature and salinity in determining seawater density. Students use a Temperature-Salinity (T-S) Diagram to examine the effect of mixing on density. A list of key concepts, essential questions, common preconceptions and more is included. These are part of the Aquarius Hands-on Laboratory Activities. (View Less)

In this lesson, students are introduced to the electromagnetic spectrum. They observe a demonstration of the visible light spectrum created by a flashlight and a prism, complete an activity sheet where they identify the wavelength that is involved... (View More) in technologies used in their communities, and learn about satellite sensors that remotely sense data. Student worksheets, a data sheet, answer keys, and Web links are included. This is Lesson 3 in Understanding Light, part of IMAGERS, Interactive Media Adventures for Grade School Education using Remote Sensing. The website provides hands-on activities in the classroom supporting the science content in two interactive media books, The Adventures of Echo the Bat and Amelia the Pigeon. (View Less)

This is a hands-on lab activity about the water cycle, specifically evaporation and condensation. Using materials such as clay, ice and a lamp, learners will observe the relationship between temperature and condensation and temperature and... (View More) evaporation. They will then draw a diagram or a concept map of the water cycle. Background information, common preconceptions, a glossary and more is included. This activity is part of the Aquarius Hands-on Laboratory Activities. (View Less)

In this lesson, students determine whether an object reflects or absorbs red, green or blue light, and create a simple spectral signature. Student worksheets and an answer key are included.
