Working with Immobilized Enzymes or Microscopic Organisms
Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

Stomata: Microscopic Openings that Let Plants Breathe
Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

Observing Water Moving Through Plants
We know plants assist in the water cycle, but how do plants get water from the ground into the air? Through a series of demonstrations or labs, scholars observe the movement of water through plants. They microscopically view the cells...

Seeing Cells
Students discuss what comes to mind when they hear the term cell and discuss what a cell is in biological terms. They look at pictures of cells and color a picture of a cell diagram, writing the job of each part as they go. After the...

Case Study Two: Shark Dissection
High schoolers read an article on sharks prior to beginning a dissection lab. As part of the lab, students identify differences between the shark anatomy and human anatomy and hypothesize why those differences exist.

Cell (Biology)
Students conduct a series of activities to explore the nature of cells. In this biology lesson, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
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...

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
Cell Division
Learners describe the cell cycle. They make a connection between DNA replication and cell division. Students describe the parts of the cell that participate in cell division and the steps of cell division.
