You Gave Me What?
Students see how an infectious disease such as AIDS may be quickly transmitted throughout a population. They conduct a simulated transmission of an infectious disease and mathematically determine the number of possible infected individuals.

How HIV Infects Cells
For this biology worksheet, students answer 2 short answer questions related to HIV based on information provided. They color and label the different parts of a virus.
Curated OER
The Dichotomy of Viruses
Students benefit from an education about these nonliving pathogens.
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.

Biology - Virus Modeling
High schoolers research one of the many types of viruses. They create a 3-D model of the virus they researched with graphics software.
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 Genome: Controversy for All Times
Students examine the genome and discuss the ethical and moral issues surrounding it. In groups, they discover the differences between ethics and morals and discuss where the concepts of good and bad come from in society. After reading...
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
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
Sets of Chromosomes
For this chromosome worksheet, students answer eighteen questions about chromatids, chromosomes, types of reproduction, haploid and diploid cells and zygotes.
Curated OER
The Meaning of Genetic Variation
Students investigate variation in the beta globin gene by identifying base changes that do and do not alter function, and by using several Internet-based resources to consider the significance in different environments of the base...
Curated OER
Genetic Disorders
Seventh graders discuss traits, traits that are inherited and how genes and chromosomes carry the code for traits. They research genetic disorders and their link to chromosome abnormalites and write a report on their findings. which...

Evidence of Evolution by Natural Selection - Testable Hypotheses
The factors that affect selection and evolution are investigated here. Information about some common ancestry examples are given but with no real scientific evidence. This presentation is very obvious in making biased claims about...
