Video Lessons and Taking Notes
Many teachers have adopted a “flipped” model of instruction, where students view lectures from home and then use class time for discussions, experiments, and problem-solving. I have not fully gone to this model because many of my lectures have been redesigned as cases and include information with a discussion and a problem to solve.…

Investigation: What Factors Affect Seed Germination?
This activity can be used as part of a unit on plants or as an activity to illustrate the scientific method. The materials are cheap and can be obtained from the grocery store. Students design an experiment to determine what factors affect seed germination. They are given a list of variables that are appropriate…

Why Does Biology Corner Have Advertisements?
When I started this website in 2001, it was a simple project required to earn my graduate degree in educational technology. At the time, all of the pages were created by writing html into a text file. It was a painstakingly long process and the pages never really looked like I wanted them to. Eventually,…

Color the Bone Matrix
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 courses also explore bone tissue and how bone is formed and repaired. The bone matrix is the hard, supportive material that makes up most of a bone’s structure.…

Color the Neuron and Neuroglia
Students can practice what they have learned about neurons with this simple coloring activity. The page shows features of the neuron, such as the axons and dendrites. They will also color the supporting cells of the matrix. There are no instructions, students must identify each of the types of glial cells: oligodendrocytes, astrocytes, microglial cells, ,…

Analyzing Graphics: The Carbon Cycle
This graphic illustrates how atmospheric carbon dioxide is produced during cellular respiration and combustion and then taken up by plants. Students apply what they have learned about the processes of photosynthesis and respiration to label parts of the graphic an answer questions. This activity is probably best done as a pair-share activity or a…

How to Use a Spreadsheet to Create a Graph
High school teachers often assume that their students know how to use basic word processing programs, internet browsers, and spreadsheets. My students come to me with very little knowledge in how to do advanced tasks in those platforms, like inserting a graph or image. I created this assignment to give students an introduction into…

Manipulate DNA in a Simulation to Explore Mutations
This activity uses a simulation from the Concord Consortium. It shows how DNA is transcribed to RNA and then turned into a protein. It’s a very clear animation and can be used on its own as part of a lecture on protein synthesis. I have even used this as a demonstration to show protein folding…
