In this activity, teachers set up five stations to provide students an understanding of light refraction, using water, microscope slides, beakers, a coin, and eyedroppers. Students rotate through the stations and record their observations on a data sheet provided with the activity. The resource is part of the teacher's guide accompanying the video, NASA Why Files: The Case of the Mysterious Red Light. ... Full description.

In this activity, student teams will create a controlled experiment by building ecosystems in two 2-liter bottles. Teams determine the control conditions of both bottles, identify a test variable, and run the experiment for several weeks to determine the role of the test variable in the system. The experiment uses living organisms such as aquatic plants or pond water microorganisms, a pH and ammonia ... Full description.

In this lab activity, student teams hypothesize which source has a greater becomes COČ concentration: their breath, auto exhaust, or air in the classroom. They test gas samples from each of these sources, plot data, and hypothesize about the respective role engine exhaust and animal respiration play in contemporary climate change. The lab procedures require Bromthymol Blue indicator solution (BTB), ... Full description.

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 occurs in the world's oceans to drive the global conveyor belt pattern of ocean currents. There is an option to conduct an investigation taking quantitative ... Full description.

In this laboratory investigation, student teams discover that the ocean's capacity to dissolve carbon dioxide depends on its temperature, and consider the effect of a warming ocean on COČ absorption. The activity requires Bromothymol blue indicator solution (BTB), Alka Seltzer tablets, household ammonia, a heat source, and laboratory glassware. The investigation is supported by the textbook, Climate ... Full description.

This experiment has student teams comparing a sample of room air with one of the greenhouse gases - carbon dioxide, nitrous oxide, or methane - and observing the relative effectiveness of the gases in trapping infrared (IR) radiation. The activity requires an IR heat source, such as a heat lamp, two 2-liter beverage bottles, #4 one hole rubber stoppers, and a thermometer or temperature probes. Nitrous ... Full description.

Students use a calorimeter made of common materials to demonstrate that energy can be measured and converted from one form to another. Hydrocarbons, such as paraffin, contain stored chemical energy; food contains stored chemical energy. The activity uses a raw potato, a nut, a candle, an aluminum drink can, a thermometer, and a balance scale. A data sheet is included in the resource. The investigation ... Full description.

This lesson is based on the concepts of frequency and wavelength, how they relate to each other, and how they correlate with the colors of the visible spectrum. The students will examine these concepts through a hands-on lab that involves measuring and timing wavelengths by pulling adding machine tape through a simple, student-made apparatus. This lab is followed up with critical thinking and performance ... Full description.

This site provides an overview of the Earth's atmospheric greenhouse effect by briefly exploring the atmospheres of nearby planets and discussing the greenhouse gases of our atmosphere, such as, water vapor, carbon dioxide, methane, ozone, and nitrous oxide. Students will learn that the heat-trapping ability of a greenhouse is influenced by a number of factors, including the transparency of the greenhouse ... Full description.
