Cell (Biology)
Students conduct a series of activities to explore the nature of cells. In this biology instructional activity, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
Curated OER
Seed Dispersion of Strawberries and Dandelions
Students investigate how seeds are dispersed on land. In this plant biology lesson, students use a dissecting microscope to study strawberry seeds and dandelion seeds, they draw what they see, then create a hypothesis on the seeds by...
Curated OER
Plankton / Phytoplankton
Students discuss the importance of plankton in the ocean ecosystem. In this biology lesson, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect global climate.
Curated OER
The Great Archeological Dig
Students explore biology by identifying a diagram. In this cell anatomy lesson, students read a story about archeology and conduct a fictitious archeology dig in class in which they search for animal cells. Students define a list of...

Dissecting Frog Embryos: Cell Membranes and Mitosis
Students use high powered dissection microscopes to dissect and examine frog embryos as well as see balls of cells that were produced by rapid division. The concept of mitosis links to the lesson.
Curated OER
Cell Size and Shape; Diffusion and Osmosis Processes
Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...
Curated OER
Biological Concepts
Learners perform a transection of a redworm. They discuss spinal cord injuries in humans. Students compare the ability of the redworm to regenerate the ventral nerve cord with the inability of humans to repair damage to the dorsal nerve...

Studying Living Organisms
Young scholars discover and discuss the differences between prokaryotes and eukaryotes. Using a microscope, they examine various prepared slides of prokaryotic and eukaryotic organisms.
Curated OER
Mushroom
Students identify the different types of mushrooms. In this biology instructional activity, students explore different mushroom experiments they can do at home. They discuss ways to extend sliced mushrooms' shelf life.
Curated OER
Cell Size Changes
Students examine the behavior of living cells treated with different types of stimuli. They watch an online movie, examine wet mount slides under a microscope, take an online quiz, and analyze data.
Curated OER
Human Epidermal Cells
Students explore epidermal cells. After following specified procedures for removing epidermal cells from their wrist, students view the cells with the use of a microscope. After creating a drawing of their observation, students label the...
