Curated OER
Cells
Students explore the cell and cell processes. They create "cytoplasm", make a model of the cell and its organelles, and simulate the osmosis and the diffusion of materials into and out of the cell.
Curated OER
Embryology as Evidence of Evolution
Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...
Curated OER
Genetically Modified Organisms
High Schoolers complete a variety of activities as they examine the ethics of (and take a position concerning) genetically modified organisms in the field of agriculture. They complete a PowerPoint demonstration to go along with the unit.

Endocrine Review Sheet
Starting with a diagram of the kidneys and urinary tract of the human, this sheet has questions about excretion, blood concentrations of hormones, gland feedback mechanisms and the effects of some hormones.
Curated OER
Genetic Testing
Complete a variety of activities to examine the pros and cons and ethical issues behind genetic testing. Your high school students will role play and examine various scenarios to determine if genetic testing is justified.
Curated OER
Plant Reproduction
Students plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Students...
Curated OER
Cell Types
Fourth graders create cartoon characters which compare and contrast two types of cells: nerve and muscle. Cartoon characters show how these two cells are similar, how they are different, and the relationship between the two cell types.

Teacher Preparation Notes on Genetics
Students explore genetics through various hands-on activities. In this biology lesson, students predict the probability of offspring genotypes and phenotypes using the Punnett Square. They explain the causes of genetic abnormalities.
Curated OER
What Can We Learn From the X Chromosome?
Students read about the X and Y chromosomes in humans and complete a worksheet.
Curated OER
Cell physiology and chemistry
Students design an experiment to discriminate between chemical diffusion, osmosis, facilitated diffusion and active transport through a membrane. Be specific about predictions and interpretations!
Curated OER
X or Y- Does it Make a Difference?
Students examine the X and Y chromosomes. In this research lesson, students use the 5E lesson model as they read articles about human chromosomes then discuss their findings and opinions.
Curated OER
Temperature and the Tomato
You will need a photovoltaic system and monitor at your school in order to obtain all of the data required to thoroughly implement this instructional activity. Your class monitors daily temperature and insolation amounts over a two week...
Curated OER
Using Amino Acid Sequences to Show Evolutionary Relationships
Junior biologists compare the amino acid sequences from fragments of five different globin molecules. They count the letter differences between each species pair. They construct a graphic representation of the evolutionary relationships...
Curated OER
Inheritance Patterns in Zorks
In this inheritance patterns worksheet, students create a visual of a Zork using chromosome strips to represent alleles from the father and the mother to determine the traits in the offspring. Students translate the genotype to the...
Curated OER
Bacterium Cell Label Me!
In this labeling a cross-section of a Bacterium cell worksheet, students use the glossary of Bacterium cell terms to help identify and label each cell part. Students label nine parts of the Bacterium cell.
Curated OER
Plastics by the Numbers
Students investigate plastic resins and their uses. In this plastics lesson plan, students describe major plastic resins and what they are used for, they compare and contrast the properties of plastic resins and they list products that...
Curated OER
The Bottom Line
Seventh graders assume the role of stockholders in a fictitious biotech company. After investigating the cloning of pets, the effects of cloning on the health and well being of the cloned animal, and the ethical issues involved, groups...
Curated OER
Blood Business
Young scholars identify the different kinds of blood. In this biology lesson, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.
Curated OER
Virus Tracker
Sixth graders will simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups will already be...
Curated OER
Elements Found in Living Things
In this elements worksheet, students review the most common elements found in living things. Students color in two pictures with the percentages of the elements found in that living thing.
Curated OER
Protein Synthesis and Words
Students explain the roles of mRNA, tRNA and ribosomes. They explain how mutations can occur in an individual. Students simulate parts of a cell to access about the process of protein synthesis.
Curated OER
Model Organisms: The Genes We Share
Young scholars gather information about gene banks. In this biology lesson, students work in groups to complete an activity sheet about genetic databases and organism genomes. Lesson includes extension ideas.
Curated OER
GMOs: Should We Grow Them?
Students examine the ethics of biotechnology and genetically modifying various organisms. They complete various activities and labs on GMOs and then write a position paper regarding their individual opinions on the subject.
