Sequence Alignment
High schoolers explore the uses of sequence alignment. In this DNA lesson students complete several experiments on sequencing and algorithms.
Curated OER
Population Patterns
Students study patterns of population growth in an ecosystem and why populations must remain in balance. They interpret basic population graphs and suggest scenarios about different population growth patterns in an ecosystem.
Curated OER
Yeast Fermentation
Students measure the temperature change involved in the production of carbon dioxide by yeast. They also identify products and reactants in a chemical and balance the equation.
Curated OER
Wildlife Habitat
Students examine habitats and describe their elements. In this wildlife habitat lesson students study the factors that affect habitat and write a short report.
Curated OER
Marine Protected Areas
Students design a research project about a Marine Protected Area they chose. In this marine biology instructional activity, students gather fish count and catch data then graph them. They create an information poster about their findings.
Curated OER
Investigating the Biosphere with Planetary Models
Students model the biosphere and manipulate variables affecting change and plan their experiments with the help of others. They describe their question, hypothesis, and methods of investigation.
Curated OER
Water Quality
Students play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.
Curated OER
Teaching about the Chemistry of Oxygen Solubility
Students explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

Human Traits
Students study vocabulary and complete a survey. In this human traits lesson students collect and analyze data then discuss what they learned.
Curated OER
Habitats and Functions
Students analyze and discuss insect diversity and all of the functions that insects perform in nature. They examine habitat and function cards, and distribute themselves by function and habitat.
Curated OER
Natural Selection
Students practice calculating allele and genotype frequencies in the framework of a simple simulation using hard candy, calculators, and a worksheet. This lesson plan includes a three-page worksheet and an assessment question for...

Alderwood Manor: A Sequential Inquiry in Environmental Bioethics
Learners explore bioethics. They discuss the traditional ethics of human conduct and man's relationship with nature. Students identify ethical dilemmas. They discuss ramifications of economic and ecological concerns with bioethics.
Curated OER
ISOLATION OF DNA FROM ONION
Students 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
Forest Management
Students explore the changes in the Sequoia forest ecosystem. They evaluate reasons for the changes and discuss opposing views of human activity, logging and fire management practices. Students observe a video, describe the location of...
Curated OER
Nature Notes
Students spend some time outdoors and record their observations of abiotic conditions, geologic surroundings and living organisms. They reflect and write about the experience of being observant in nature.
Curated OER
Stream Chemistry Monitoring
Learners become familiar with real-world gathering of chemical data. The experience how the science is done: the nature of analysis, data collection, interpretation, and presentation. They study a nearby body of water for their experiment.
