Watershed Awareness
Students investigate the relationship between upstream influences in their watershed and the watershed's estuary. They apply the scientific process to test a hypothesis while examining the impact of upland activities on estuaries.
Curated OER
Testing Growth of Algae
Students participate in an experiment in which they test the growing rate of algae. They test the algae in different elements recording their observations. They share their results with the class and discuss.
Curated OER
Teaching the Chemical and Structural Properties of DNA
Learners work together to answer questions about DNA. They identify where DNA is found and its function in the cell. They note any physical similarities they have with their family members
Curated OER
Extraction of DNA from White Onion
High schoolers investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.
Curated OER
Devising a Set of Experiments to Test Water for Dissolved Substances
High schoolers work together to test water samples for pollutants. They design data tables to collect and record their observations. They complete discussion questions to end the lesson.
Curated OER
DNA and RNA
Tenth graders research the history and discovery of DNA. Using their text, they label a basic DNA structure and the composition of genes. They explain how RNA and DNA differ from one other and discuss the processes of transcription and...
Curated OER
Minerals
Students become aware of the amount of different kinds of minerals are needed to maintain our standard of living by observing the worksheet. They study how it requires production of 40,000 pounds of new minerals and metals every year for...
Curated OER
ISOLATION OF DNA FROM ONION
Learners perform a lab in which they extract DNA from onion cells. Students break through the cell and nuclear membranes and then break down the protein that the DNA is wrapped around.
Curated OER
Molecular Evolution in Plants
Students are using a paper chromatography study that is suitable for introductory biology. The absorption spectra studies and gel electrophoresis studies are appropriate for students who have complete both introductory biology and...
Curated OER
This Stuff Makes Me Sick
High schoolers participate in a lab showing the effects of pesticides on Lumbriculus variegatus. Several extensions and variations are also included in this lesson including one which relates the experiment to how pesticides enter our...
Curated OER
Molecular Evolution in Plants
Students examine chlorophylls. They explore the absorbing pigments in a variety of plants. Through activities, students determine spectrophotometrically. They compare plant proteins from the family Brassicace to assess the level of...
Curated OER
Is Your Water Clean?
Students conduct tests of water samples from different sources, such as a local river, tap water, and an irrigation ditch. After determining which pollutants are present in each sample, students hypothesize the possible sources of the...
Curated OER
Water Pollution Graphing Activity
Students describe and identify the link between land use activities within a watershed and water quality. They evaluate the quality of a "water sample" ( a bag of skittles), graph their results, and form a hypothesis about the land use...
Curated OER
DNA Replication
Students construct a 3-D model of DNA. They demonstrate an awareness of base pairs in written work and in a model. Students model DNA replication using edible materials. They record concluding thoughts in their science notebooks.
Curated OER
Nutrient Biochemistry
In this nutrient biochemistry learning exercise, students complete the blanks with information about nucleic acids and the process. Students also draw a figure referenced in the text given.
Curated OER
Water Quality Survey: Monitoring the Sustainability of Pigeon Creek
Students research the History of Pigeon Creek (or any watershed in your area). For this environmental science lesson, students conduct field tests such as pH and nitrates. They collect data and compare what they collected with other groups.
Curated OER
Building a Model DNA
Students explain the function of DNA in the body. In this biology lesson, students build a DNA model using simple materials. They demonstrate how bases pair up in the helix.
Curated OER
Mixtures, Percentage and Equation Stoichiometry
In this chemistry worksheet, students answer 2 problems on solution stoichiometry. They calculate the mass of products formed given a certain amount of reactant.
Curated OER
Ecology: Effects of Land Use on Natural Streams
Eighth graders examine how humans affect various ecosystems. In this ecology lesson plan, 8th graders discuss different ways that contaminants enter the stream. They explain the consequences of eutrophication in lakes.
