Sea Water Mixing and Sinking
Middle schoolers investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.
Curated OER
Earthquakes
Students observe the melting of ice. In this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

The Effect of Rain on Morning Temperatures
Eighth graders study the effects of the water cycle. They create a graph of the air temperature versus solar radiation on a rainy and clear 24 hour period using data from a provided link. Afterward, they answer questions to determine the...
Curated OER
A Limnology Study of Drainage Ditches
Students chemically test water, observe microscopic organisms in the classroom, and screen the sample for macroinvertebrates. They design a reporting sheet that list all the items to be tested and a space to record the results.
Curated OER
Season's Greetings
Students explore Earth's seasons using an interactive website. For this earth science lesson, students watch video segments and explain Earth's seasonal milestones. They discuss the factors that causes seasonal changes.
Curated OER
If I Were A Raindrop!
Students review the water cycle. In this water cycle lesson, students review the different stages of the water cycle. Students use the computer program Kid Pix Weather to help demonstrate understanding.

Mass and Density of an Irregular Solid
In this physics worksheet, students determine the density of irregular solids using water displacement method to complete 7 problems and short answer questions.
Curated OER
Greenhouse Effect
Learners investigate the greenhouse effect. In this environmental lesson, students investigate why the greenhouse effect changes the climate through an experiment. Learners use vinegar to simulate how acid damages the environment.
Curated OER
What are the Challenges?
Pupils discuss energy. In this energy challenges instructional activity, students read about greenhouse gas emissions and global climate change. Comprehension questions from the reading are provided.
Curated OER
Lesson Plan: Global Warming
Students explore the concept of global warming. In this climate change lesson plan, students explore the provided links to PBS NOW sources and research the greenhouse effect and the effects of global warming. Students support their...

Junior Engineering Surface Water
Students experience the effects of pollution and erosion on a model of a watershed and explore ways to change the outcome.
Curated OER
The Work of Waves and Wind
This is not revolutionary, but it is informative. Earth science viewers in grades 7-12 get carried away with wave and wind erosion. They view diagrams of how waves impact ocean shorelines. They see examples of the different types of sand...
Curated OER
WATER FROM HERE TO YONDER
Students identify local watersheds and drainage areas by using maps and other resources. They are given copies of the water cycle. Students discuss the movement of water in the environment. They observe, record and transfer information...

Surface Air Temperature Trends of the Caribbean
Students investigate the seasonal changes to sea surface and near-surface air temperatures near the equator. They use actual satellite data to track and graph the differences in air and sea temperatures during different seasons in the...
Curated OER
Temperature Changes: Atmosphere & Ocean
Young scholars observe temperature differences of water and air in sunlight and darkness. They determine that the sun warms the Earth's surface, which controls global currents and climate, keeping the earth habitable. They discover water...
Curated OER
Water, Rivers & Topography
Students explore the topography of Idaho and the importance of surface water and drainage. using digital maps, they inspect the courses of major rivers, Yellowstone Hot Spots, and the natural landscaping of Pocatello. Students explore...
Curated OER
Images of Our Changing Earth
Students identify and explain that remote sensing can detect changes on the Earth's surface that occur over time, and name at least three: urbanization, deforestation, and succession. They select a global change issue to investigate and...
Curated OER
Change Agents
Third graders experiment with three erosive change agents. They do an observation log, which they present to the class through a song, poem or skit.
Curated OER
Strength of Water
Students perform experiments using flexible bottles of water and eyedroppers partially filled and placed in the bottle. They record what happens when they tighten the bottle lid and squeeze the bottle.
Curated OER
Miniature Water Cycles
Students construct a model of the water cycle in action using two-liter pop bottles to build a terrarium. Locate examples of evaporation and condensation in the water cycle (e.g., water evaporates when heated and clouds or dew forms when...
Curated OER
Water Currents
Pupils demonstrate how ocean currents are influenced by changes in density. They discover that temperature and salintiy affect density as well. They participate in a short experiment to end the lesson.
Curated OER
Water Table
Students predict from a rock sample whether a water well could be drilled in that type of rock. They predict what conditons would be necessary for the well to produce water.
