Hairy Evidence! Hair Identification
Provide a mystery hair and a set of reference hair samples for middle school investigators to place on a slide and examine under a microscope. Materials and procedures are detailed on the first page, while a data table for drawing what...
Curated OER
Cell Structures and Their Functions
Life science learners investigate live cells. They examine wet mount slides of cyanobacteria and Elodea plants. They peer into the dynamic microscopic world of protists. Afterward, they construct a model of a cell, including rudimentary...
Curated OER
Microscope Mania
Students examine parts of a microscope and how to use a microscope at five lab stations. They identify parts of a microscope by describing the differences between low power and high power. They visit Internet sites (included in the...

Cells: A First-Hand View
In the first of two activities, your charges prepare wet mount slides of cork and bean sprout cells in imitation of Robert Hooke's historical investigation. An excerpt from his notes is included. Then, investigators compare animal cells...
Curated OER
Cell Size Changes
Learners 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
Introduction to Biology
Students examine a microscope and learn its functions. In this microscope lesson students prepare a wet mount slide and complete calculations.
Curated OER
Pond Life Identification Kit
Learners explore ecology and biodiversty. They use the wet-mount procedure to make several slides to view using the microscope and draw what they see.
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.
Curated OER
The Hidden World
Students examine dust mites and other allergens. In this dust lesson students complete a lab activity on dust mites.
Curated OER
SEXUAL LIFE CYCLE DEVELOPMENT USING MONOCYSTIS
High schoolers perform a lab to becoe familar with scientific concepts. The skill of inquiry is essential and this lesson furthers its development. The intelligence of kinesthetics is used as learners perform the many aspects of this lab...
Curated OER
Studying Living Organisms
Students discover and discuss the differences between prokaryotes and eukaryotes. Using a microscope, they examine various prepared slides of prokaryotic and eukaryotic organisms.
Curated OER
The Effects of Osmotic Balance and Imbalance In Living Cells
Students investigate osmotic balance in living cells. In this osmotic balance lesson plan, students use elodea leaves to study the effects of salt solutions on the cell. They compare the changes in an elodea leaf with salt water on it to...
