Biology: Natural Selection
Students explore evolutionary processes and theories using the spotted fish applet. They observe what happens to fish in a closed environment with both food and predators. Students run the model several times and answer questions about...
Curated OER
Simulation of Gene Splicing
Students simulate gene splicing by examining bacteria. They create a bacterial DNA into which they insert the human DNA (gene) that codes for growth hormone. They cut the sites of the enzyme to study how the human DNA can be joined to...

Using Yeast as an Ultraviolet Light Measurement Tool
Students accurately measure the relationship between radiation dose and either survival or some genetic event such as mutation or recombination. They investigate the damage that was done to the DNA molecule as a result of exposure to...
Cornell University
Bacteria Take Over and Down
Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Science Lesson: Chocolate Flavored Cherries
Students are able to identify start and stop sequences in DNA. They are able to model using restriction enzyme and ligase to remove sections of DNA and reattach them. Students are introduced to the process of recombinat DNA through the...
Curated OER
Modeling Mitosis and Meiosis
Students construct and manipulate models of mitosis and meiosis and compare/contrast them. They create the models using index cards and yarn, interpret diagrams and photographs, and summarize written descriptions.
Curated OER
Spork and Beans
Students examine natural selection, how it works and how it can cause microevolution. In this evolution lesson plan students complete a lab activity that shows the effects that natural selection has on organisms.
Curated OER
Lesson 16: DNA Technology
Students research different areas of biotechnology. In this biology lesson, students create a presentation about their research. They debate the topic presented and share their views on the subject.
Curated OER
Mammals: Mammals and Their Ways
Students study the difference between innate and learned behaviors. They observe the adaptations and behaviors of mammals in this series of lessons.
Curated OER
Time Conceptualization
High schoolers use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little...
Curated OER
The Beaks of Finches
Students examine how species evolve over time and how this can change a population. In this environment lesson students complete a worksheet on finches.
Curated OER
The Beaks of Finches
Students study finches and how they have evolved over time. For this finch review lesson students fill out a key points worksheet then divide into teams and complete an activity.
Curated OER
Biotechnology
In this biology worksheet, students complete a crossword puzzle with 23 questions on biotechnology. They identify the benefits and ethical issues about biotechnology.
Curated OER
High Tech Food
Students view videos, read, and fill in charts about agriculture production. In this agriculture lesson plan, students complete these agriculture activities and explore careers in agriculture.
Curated OER
BIO205-CH1- Intro Word Search
In this word search worksheet, students locate words related to biology. The word list includes protists, viruses, plants, spiral, and biotechnology.
Curated OER
How Things Go Wrong
Students identify where mutations might occur and examine what effect those mutations will have through class discussion of DNA replication and cell division. Students then differentiate between mutations that affect individuals and...
Curated OER
DNA Chips
Students discover what they need to know about DNA chips. They extend this knowledge to analyze gene expression data to diagnose two kinds of leukemia.
Curated OER
DNA Chips
High schoolers explore issues surrounding DNA microarray technology. They focus on a single area of biomedical research to help them explain how science, people, ethics, and history all fit together. They analyze gene-expression data.
Curated OER
Time Conceptualization
Students relate the number and length of generations in their living family members to the number of generations that have passed since specific events in recorded history. They then apply this time conceptualization to the number of...
