Fourth graders examine patterns that influence population density in the various regions of California. The unit's three lessons utilize graphic organizers for the interpretation and presentation of data.
Curated OER
Biomes: Extreme Climate
Students create a web connecting global warming, the Arctic, and wold climate. They write a paragraph explaining the role of the Arctic in world climate.
Curated OER
Extreme Climate
Students discuss global warming, greenhouse effect, permafrost and other key words. In this climate lesson students create a web that connects global warming, the Arctic and world climate then write a paragraph explaining the role...
Curated OER
Lake Ice Out Lessons
Students explore the greenhouse effect. In this environment instructional activity, students describe how "ice out" affects animals and plants who live in a Maine lake. Students graph "ice out" data and make predictions about...
Curated OER
Ocean Color
Learners examine NASA's SeaWiFS Project Web site to explore how the SeaWiFS Project monitors environmental and climatic changes in the oceans and atmosphere. They answer questions and write a summary in support of continued funding for...

Bonneville Salt Flats Ecosystem
Students discuss the annual ecosystem changes of the Bonneville Salt
Flats and the artificial changes made by man.They observe the annual ecosystem changes and the current additional flooding of the Bonneville Salt Flats by man.
Curated OER
How's the Air Up There?
Learners experiment with soda cans and water to discover why air pressure is greater closer to Earth's surface.
Curated OER
Canned Heat
Learners demonstrate that light and dark colored objects absorb the sun's radiation at different rates. They experiment with the temperature change of water in two locations and discuss the results.
Curated OER
Leaf Transpiration
Young scholars determine the amount of water loss due the transpiration.
Curated OER
Oceanography
Fifth graders study the topography of the ocean floor. They determine its ever changing nature as they examine currents and trade winds. They write paragraph describing how the winds might affect land formations after the discussion of...
Curated OER
Earth's Energy Balance Performance Standard
Students examine how Earth-Sun relationships affect Earth's energy balance and the pattern of world temperatures. Students study a Surface Temperature Regions map and write a paragraph describing the temperature pattern from the Equator...
Curated OER
A Message in a Bottle
Students investigate the motion of water currents by mapping the possible movement of messages cast into the ocean in bottles.They accurately plot the appearance of bottles on a world map and illustrate the flow of an ocean current...
Curated OER
Set the Stage
Students observe evaporation in a controlled environment. Evaporation is the change of liquid water into water vapor (a gas). The rate of evaporation is determined by many factors such as air temperature and humidity, liquid temperature...
Curated OER
Glaciers and How They Form lands
As a whole class, the students define glacier and perform an experiment involving glaciers. The students brainstorm ideas of what a glacier is, and narrow the ideas down to a definition. The students then participate in an activity that...
Curated OER
Arsenic Contamination: Natural Disaster or Human Induced?
High schoolers list as a class the sources of arsenic contamination of water. They describe the major health effects of arsenic contamination in a letter. Students identify the regions that are affected by it.

Curated OER
Erosion in Different Soils [Erosion Races]
Fourth graders review how erosion can happen by wind, water, and gravity which they studied in previous lesson. They attempt to discover if all soils erode at the same rate. In small groups, 4th graders experiment with three different...
Curated OER
Archaeobotany
Pupils study pictures of seeds and the conditions in which they grow during their study of archaeobotany. They infer ancient plant use by looking at archaeobotanical samples. They determine the change of plant use by interpreting a graph...
Curated OER
Coal Formation
Students create a condition in an aquarium which allows the formation of coal. Students observe changes in decomposition and color of materials present in aquarium before a coal layer appears. Plant "fossil" imprints will be left behind.
