Curated OER
Determination of Overall Water Quality Using a Quantitative Macroinvertebrate Survey
High schoolers examine water samples from a local stream. They identify various types of macroinvertebrates found in that water ecosystem and perform a quantitative macroinvertebrate survey to determine the stream's water quality.
Curated OER
Bioremediation
Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.
Curated OER
Sediment Tubes
Young scholars observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.
Curated OER
Did You Say Water Bugs?
Second graders observe live specimens of aquatic insects in a water habitat. They study specimens from both moving and still water with the naked eye and a hand lens.
Curated OER
Grain Properties Activity
Students study the similarities and differences of five different grains. They analyze the characteristics of corn, sunflower, milo, wheat, and soybeans.
Curated OER
Water Quality
In this unit of lessons, 2nd graders examine the water quality of the water on the planet. They discover how much water is on the planet and how to conserve their water usage.
Curated OER
Do You Dig Wetland Soil?
Students study the physical differences between wetland and upland soils. They match colors to the different levels of the soil after digging holes. They create soil color charts and chart the texture of the soils.
Curated OER
Decomposition
Students are introduced to the concept of decomposition. They examine decomposition in their school orchard. They write about their findings in a journal.
Curated OER
Investigating the Uses of Backyard Bacteria
Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.
Curated OER
Snail Observation Exercise
Young scholars are given a pond snail in a clear glass and asked to make observations on the snail's form and behavior. One of the key ideas is that seemly common subjects (like snails) often have surprising or interesting properties.
Curated OER
Introduction To Floral Morphology
Middle schoolers create a model of the four basic whorls of flowers using a water bottle, construction paper and Q-tips. They then examine fresh flower specimens to see how the basic structure can vary in different species of flowering...
Curated OER
Is Soil Alive?
Third graders observe soil samples. They then form hypotheses as to whether or not soil is alive. Students read and discuss information about soil and components of soil. They state wheter or not they believe soil is alive and list...
Curated OER
Exploring Ecology
Students explore the basics of ecology through numerous hands-on and relevant activities. They participate in an online food chain demonstration, which explores food web dynamics. They dissect owl pellets, examine the prey's bones, and...
Curated OER
What Stages Do Insects Go Through?
Fourth graders observe mealworms over a period of time and record any changes they observe. They record any changes in color, length, behavior, and any other noticeable changes, identify the stages of the mealworms, and create a chart...
Curated OER
Origins: Earth is Born
Students collect and identify micrometeorites from space. Students create collection devices and retrieval methods for matter. They prepare slides and view particles found. Students discuss where the identifiable particles originated...
Curated OER
Beach Sands of the World
Students examine a variety of sand samples from throughout the world. On an index card, they write the characteristics of the sand and draw what the grains look like to use during the activity. Using a map, they practice plotting...
Curated OER
LASER HOLOGRAPHY
Learners study holographs. In this laser holography instructional activity students make a laser holograph and understand why it works. This can be done as a class.
Curated OER
Microorganism Multiplication
Seventh graders complete two experiments to learn about harmful and helpful microorganisms. In this microorganisms lesson, 7th graders read background information about fungi, yeast, and club fungi. Students then complete two experiments...
Curated OER
Rock Identification Lab
Eighth graders compare and contrast the three different types of rock. In this earth science lesson, 8th graders classify rock samples according to their correct rock type. They design their own data collection table.
