Hydrology: Flood Mitigation
Twelfth graders discuss the factors that affect flooding. In this environmental science lesson, 12th graders analyze rainfall data about flooding. They complete a scavenger hunt worksheet using the internet.
Curated OER
Land Use and Nitrogen
Students consider the effects of development on water quality. They test nitrogen levels in waters before and after development, investigate wastewater treatment options and research best management practices to reduce nitrogen loads.
Curated OER
Wastewater
High schoolers discuss what happens to their wastewater. They read about the wastewater treatment process. Students are asked what types of things get flushed down toilets or goes down drains in sinks and showers. They are taught what...
Cornell University
Atomic Bonding
Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...
Curated OER
Snowfall
Students examine the differences between snow and rain. In this precipitation lesson, students measure one inch of rain and snow to calculate the amount of liquid water. Students use a snowfall "conversion" chart to measure how much...
Curated OER
Celebrate The Four Seasons
Students investigate cause and effect and compare and contrast how recurring cycles are evident in multiple aspects of their education. They answer questions in the chosen field. Students model each aspect by interpreting, perceiving and...

Rain Machine (Solar Still)
Students experiment with a solar still. In this distillation lesson, students find a simple way to use evaporation to make salty water drinkable.
Curated OER
How Do You Dew?
Students examine how the processes of condensation and evaporation occur. They describe the relationship between heat energy, evaporation and condensation of water on Earth. They give examples of the processes of evaporation and...
Curated OER
Environment: Just Around the Bend
Students decipher landforms on a map and corresponding satellite imagery. They consider the impact of pollution on agriculture and water. They draw diagrams demonstrating how pollution works its way into the food source.
Curated OER
Intermediate Activity: Energy Guide Labels
High schoolers explore energy efficient appliances. In this economics and ecology lesson, students compare and analyze EnergyGuide labels of various appliances. High schoolers discuss federal government involvement with consumer...
Curated OER
Carbon and Oxygen Cycles
Students construct their own diagrams outlining the pathway of carbon and oxygen in the atmosphere. Students explain their diagrams outlining the pathway and teacher checks for accuracy and completion.
Curated OER
The Treatment of Wastewater
Learners, through a series of lessons, study the various processes of treating wastewater. They participate in discussion and complete various worksheets and a hands-on activity, in which they observe the processes of filtration and...
Curated OER
Science: Seeds to Plants
First graders compare and contrast different seeds before planting them. They assess the basic needs to plants and conduct experiments of deprivation of those needs. They write stories and draw pictures of plants which are bound into a...
Curated OER
Brine Shrimp
Students gain a sense of the delicacy and complexity of a living organism and the rather narrow range of conditions under which it can live.
Curated OER
Plants
First graders explore the specific needs, characteristics, and uses of plants. They discuss the needs of plants as they grow. Students observe plants in various settings as they grow and note the changes they see.
Curated OER
Web of Life - Ecosystem
Third graders play the roles of various organisms in an ecosystem (focusing on insects) and pass yarn or string around to other organisms from largest animals to the smallest. The end product is a web which shows how all of these animals...
Curated OER
Snow on Sea Ice
Students examine different samples of ice and predict the amount of snow that has fallen in a given year. Using a calculator, they graph the various thicknesses. They analyze the graphs to determine the relationship between the snow and...
Curated OER
Estimating Altitude of Water Cloud Base
Young scholars conduct an experiment to determine dew point and use a formula to detemine altitude. They construct a chart and predict what altitude clouds would form, given the dew point on the ground.
Curated OER
Butterfly Pavilion
Young scholars learn about butterflies through books and observation in a butterfly pavilion. In this butterfly pavilion lesson plan, students use hand lenses to observe the metamorphosis of the butterfly and record in their journals....
