Curated OER
Teaching about Fish Stocking Decisions
Tenth graders complete a directed study, form the internet, and then complete activities.
Curated OER
Beaches of the Delaware Estuary
Students examine estuaries in Delaware. They, in groups, gather samples of water to find organisms and identify them.
Curated OER
Analyze the Results
Students conduct water tests and sample macroinvertebrates from a nearby source to make a general determination about the overall quality of water. They use worksheets and analyze data as part of a larger unit.
Curated OER
Water Quality Monitoring
Students work together to gather water samples. They compare and contrast the water quality from different places in the community. They answer discussion questions to complete the lesson.
Curated OER
Primary Producers
Students examine the role of carbon in the oceans and how phytoplankton determine the levels present. In groups, they practice measuring primary productivity using two methods. They use the internet to research the role of phytoplankton...
Curated OER
Quick Freeze (Demonstration)
Students witness an demonstration in which a bottle of club soda will go from a liquid to a solid when it is opened and the carbon dioxide is allowed to escape. This will help them understand that the freezing point of a solution will...
Curated OER
Geography Action! Rivers 2001-Runoff
Students experiment with how rain affects topsoil using dirt and red tempera paint. At the end of the activity, students find red water in their collection jar, representing nutrients in the soil.
Curated OER
Solubility and Chemical Changes in Groundwater
Middle schoolers test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH...
Curated OER
Smog Be Gone
Learners begin the instructional activity by identifying greenhouse gases. In groups, they observe and record the effect of the gases on the atmosphere and the temperature of the Earth. They participate in activities that describe the...
Curated OER
Layering of Water
Students examine what happens when different types of water meet. In groups, they participate in an activity in which they combine different percentages of salt, fresh and brackish water and record their observations. They let the...

BrainPop-Acids and Bases
In this acids and bases worksheet, students use a word bank to complete 33 fill in the blank questions about the Acids and Bases movie found on the website www.brainpop.com
Curated OER
Water Quality
In this water worksheet, students determine the factors that effect the solubility of gases, calculate the percent concentration of solutions, and give the balanced chemical equation for photosynthesis. This worksheet has 18 short answer...
Curated OER
What Trout Need
Learners investigate the important components for a healthy trout habitat. In this fish habitat lesson, students discuss how the aquarium will simulate a trout's environment in nature. Learners complete a trout information sheet to set...
Curated OER
Into the Pond
Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.
Curated OER
Structure of the Earth System
Eighth graders describe the steps in the water cycle. They discuss factors that affect runoff and explain the differences between stalactites and stalagmites. They discover the importance of ground water.
Curated OER
Fallout!
Students plot the locations of fallout from two disasters that polluted much of the world's air. They plot the ash fallout from the 1980 Mt. St. Helen's eruption to see what the wind patterns in the United States look like overall. Next...
Curated OER
Air Pollution Over Where?
Students predict the movement of an air borne pollutant using their understanding of air currents. They determine which governments and/or communities should be contacted to be forewarned. They also explore the properties of their...
Curated OER
Drifting Continents, Dynamic Results
Pupils plot earthquake and volcano data using a Compass Rose Plotting. They explain the relationship between plate movement and connection. They draw conclusions that earthquakes and volcanoes occur in predictable locations.
Curated OER
Growing Crystals
Students are introduction to the cause and effect of a chemical reaction between water, mucilage glue, and magnesium sulfate as they form crystals.
Curated OER
DNA Extraction From a Variety of Tissue Samples
Students, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.
Curated OER
Color Burst
Learners gain experience in asking questions and conducting inquiry by exploring the separation of colors in water and other solvents; to communicate and share findings of student investigations.
Curated OER
Fresh Water From the Oceans?
Students participate in an activity in which they demonstrate how the evaporations of water from the oceans results in fresh water in the form of rain. They create a saltwater solution in a flask and boil the water until most of the...
