Curated OER
Light Microscopes
Seventh graders study the parts of a light microscope, and its proper use. They identify each part and explain why it is important to know how to use this tool. They practice observing newsprint on a wet mount slide.
Curated OER
Extraction of DNA from Onion
Students study DNA by isolating it from plant tissue. They determine the purpose of each step in the isolation procedure as it relates to the physical and biochemical characteristics of the genetic material
Curated OER
Extraction of DNA from White Onion
Students investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.
Curated OER
DNA: What Does It Mean?
Tenth graders explore DNA using online tutorial. They perform their own DNA extraction from a clove of garlic and identify the key components of DNA.
Curated OER
Observing Osmosis in a Chicken Egg
Tenth graders develop a hypothesis and explain what they observed on an activity. In this investigative instructional activity students observe osmosis and report their data using a graph.

Describe the Perfect Pathogen
Young scholars develop a pathogen based upon their knowledge of pathogens and after presenting it to the class, they then suggest ways that the pathogen might be combated. Next they identify possible physical or behavioral changes in a...
Curated OER
What Is an Egg?
Students identify the parts of the egg and observe the composition of the egg parts.
Curated OER
Skeletal, Skin, and Muscular Systems
Eighth graders explain the functions of various body systems. Using a concept map, 8th graders identify and explain the fuctions of the skeletal, skin, and muscular systems of the body. After completing their concept map, students...
Curated OER
Polytene Chromosomes from Salivary Glands
Students use this laboratory procedure to outline the mechanism by which salivary glands are removed and prepared so that the polytene chromosomes may be observed.Drosophila virilis is used instead of Drosophila melanogaster because D....
Curated OER
Does the Chicken have Anthrax (Explain I)
Students explain how each of the components of innate immunity function in the protection of the body. Following an investigation, they articulate how innate immunity functions.
