Cell Labeling: Simple and Complex
Students practice labeling organelles on a simple model (2D) and a more complex model. The idea is for students to gain an appreciation for how cell diagrams are created. They don’t all look alike, and are often artistically created. Cell organelles tend to follow basic design rules, like the mitochondria will generally look like a…

Using Anchoring Phenomenon with Lessons
Start lessons on osmosis with an activity and anchoring phenomenon. View cells exposed to salt and observe how they change!

Cell Structures: A Graphic Organizer
This graphic organizer (concept map) organizes the cell structures around three main parts of the eukaryotic cell: the nucleus, cytoplasm, and cell membrane.

Photosynthesis Coloring
Students read short text passages and then color images to help them relate the textual information with the graphic.
-
Cell Cycle Labeling
Students label the image of a cell undergoing mitosis and answer questions about the cell cycle.

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.

Case Study: How to Survive a Cholera Epidemic
In this case, students explore how cholera is spread and how it affects the body. The case is divided into four sections, with the first part focusing on the role of clean water supplies and the spread of bacteria. In the second part, the affects of the bacteria are examined, with attention on how the…

Investigation: Mitosis and Cancer Cells
The first part of this investigation, students examine slides of mitosis in an onion root tip and count the number of cells in each phase of the cell cycle. An equation is then used to estimate the percentage of time the cell spends in each phase and students create a bar graph to display results. …

Investigation: Taste Buds and Signal Transduction
As a part of the chapter on cell signal pathways, students perform a lab that examines how their taste buds are affected by Gymnema. For this lab, I simply placed a question on the board “How does Gymnema tea affect your ability to taste sweet foods?” I provided them with a list of…
