Cell Cycle Label
This worksheet was created for freshman level biology and is a simpler version of a worksheet I use in the advanced classes showing the cell cycle. The image shows a cell in interphase, prophase, metaphase, anaphase, and telophase. Students label each phase and then identify structures within the cell that are important for cell division,…

The Tardigrade Project
This project was created for AP Biology students where they scrape lichens from trees near campus and filter them over night so that tardigrades and other microorganisms can be collected from the water.

Comparing the Ameba to the Paramecium
With the adoption of NGSS, I’ve had to make cuts to some of the lessons that biology classes of the past enjoyed. I was sad to see it go, but we no longer do a unit on the Kingdom Protista, but I still manage to fit a microscope lab into other sections.

Investigation: Comparing Plant and Animal Cells
This simple investigation asks students to view cells under the microscope and compare differences between plant and animal cells. Students are instructed in the procedure for removing the epithelial cells of an onion and staining with iodine. These cells are fairly easy to see and most beginning students will have no trouble locating the…

Bone Matrix Anatomy (Coloring)
Anatomy students learn about the skeletal system, where they examine bones and how the bones fit together to make up an entire skeleton. In addition, some course also explore bone tissue and how bone is formed, repaired, and even broken down to release minerals. The bone matrix is composed of cells called osteocytes…

Investigation: What Organisms Are Found in Ponds?
Does your community have ponds, streams, or lakes? Students enjoy working with real biology, and though it may not be possible to take students to a lake, you can bring the lake to the student. This open-ended activity gives students the opportunity to explore pond water and compare the types of species found in…

Investigation: Bacteria
This investigation asks students to take samples from the school and grow bacteria on agar plates. Students learn to use sterile technique to transfer and stain the bacteria and view under a microscope. Lab guide includes instructions for how to analyze and compare colonies and identify the three shapes of bacteria: bacillus, cocci, and…

Investigation: What Factors Affect the Heart Rate of Daphnia
This investigation starts with a guided procedure where students gather data on the heart rate of daphnia when the organism is exposed to 1% ethanol. Daphnia are tiny crustaceans that are visible with the naked eye, though a microscope or stereoscope will be needed to see their heart rate.

Investigation: What Are the Different Types of Cells?
Students look at cells from different domains and kingdoms; compare the size of cells and how their structure and shape differ depending on their function.
-
Color a Typical Animal Cell
This worksheet requires students to color a drawing of animal cell according to directions, intended as practice or reinforcement for a unit on cell biology.
-
Comparing Plant Cells
Students observe onion cells and elodea cells using the light microscope. Students compare structures found in each type of cell and create drawings.

Why I Teach Pathology in Biology
When you examine the AP Biology Course Description, there is no mention of pathology (the study of diseases) in the list of Big Ideas. Bacteria are mentioned in the context of comparison between prokaryotes and eukaryotes, lines of descent, and endosymbiosis. Viruses are mentioned within the context of genetics and how DNA can be transferred…
