Mountain Pine Beetle
Students identify the different parts of a tree. In this biology lesson, students investigate how mountain pine beetles kill trees. They examine the beetles' anatomy using a microscope.
Curated OER
How Organisms Respond to Changes in their Environment
Students observe the reaction of living cells to mechanical and chemical stimuli by introducing different stimuli to an organism under a microscope and recording the response.
Curated OER
Cells, The Structural and Functional Units of Life
Students observe the general structure and organelles of plant and animal cells. Students prepare microscope slides of elodea, onion, check, and cork and identify the cells by size and shape as unicellular, multicellular, plant or animal.

Pollen Tube Growth
Students demonstrate the proper usage of the compound and dissecting microscopes. They identify the parts of a flower and the functions of the flower parts. Students describe the process of gamete formation and fertilization in a flower.
Curated OER
What Kind of Insect is That?
Fifth graders characterize insects and classify insects according to the Linnaean system. They use hand lenses or microscopes to examine insect body parts.
Curated OER
Cell Observation Exercise
Students take measurements of the distance between the objective and the slide when in focus with each objective. They determine the diameter of the field of view at each power in order to determine the size of the cells being observed.
