Dragon Genetics
Add a little fantasy to your genetics unit by having students practice doing genetic crosses using dragons as specimens. Dragon traits include fire breathing, wingless, and color. I have students practice on whiteboards as we work through the slides and then I have students share their solutions with the class. The level 2 questions include…

Review with Whiteboard Panels
In order to review for final exams and to also tie together the semester, I had my students create boards that summarized the labs they did during the semester. I choose 6 labs so that each group of three would be able create a whiteboard panel and do a mini presentation to the rest of…

Demonstration: Can Yeast Digest Lactose?
This activity can be performed as student lead inquiry lab or as a class demonstration activity. Students should have a basic understanding of how enzymes work and the relationship between lactose and lactase. If you use Openstax, this is a great lesson to bridge the chapter on enzymes to the next one on respiration and…

Cell Membrane and Transport
This reinforcement worksheet displays a graphic of the cell membrane showing the phospholipid bilayer and embedded proteins. Students identify structures within the bilayer and use reasoning to determine how molecules are moving across the membrane in response to a hypertonic solution. Worksheet was designed for freshman level biology classes who are studying osmosis and…

Color the Bones of the Hand
Learning the names of the bones of the hand can be challenging. This coloring worksheet can be used with a lesson how how to locate each of the bones. I also teach students a mnemonic, though they still need to establish where the scaphoid bone is for the mnemonic to work. They find each of…

McMush Lab
I designed this investigation for AP biology though it could be modified to work with students in introductory biology classes. First students learn the four macromolecules important to life: carbohydrates, lipids, proteins, and nucleic acids. They can then venture into the lab where they use indicators to test for the presence of these molecules in…

Investigation: Properties of Water (with Stats)
This investigation asks students to review the properties of water as they relate to life, usually a topic covered in the first or second chapter of most biology textbooks. Students then perform an experiment where they test the number of drops that can be placed on penny and compare that test to drops that…

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…

Flashcard Creators and Templates
If you teach a class that requires students to memorize information, then you have probably worked with students on developing strategies for memorization. I often tell my anatomy students that they might forget some of the details of what they have learned, but study strategies will stay with them through college. I could get…

Investigation: Tools and Measurements
I designed this activity to help students become familiar with basic equipment found in the lab. Students take volume measurements using a graduated cylinder, beaker, and a 3ml pipette. Ultimately, they must determine how many single drops of water are in 1 milliliter by designing a way to test this given the tools provided.…

Feedback Loops: Insulin and Glucagon
The Next Generation Science Standards includes feedback loops and homeostasis as a standard for life science. While homeostasis is a theme for many units in biology, feedback mechanisms are fairly specific. In fact, this is probably the most oddly specific topic found in NGSS. If you are trying to include it, most younger students…

Investigation: Processes of Science
Students must develop their own causal question about what biological factors affect a person’s lung capacity, Then test their hypothesis using a respirometer.

Demo: BTB and Carbon Dioxide
I have used this demonstration every year to introduce the scientific method. The worksheet below is optional and includes instructions for writing a lab report and doing a more involved investigation, but for the beginning of the year, I prefer to just have students observe and give their suggestions for how to test various hypotheses.…

Investigation: Why Are Cells So Small?
This activity requires students to practice math skills by measuring the surface area and the volume of boxes. Collect boxes for students to use, these can be any type of box, such as tissue boxes, food boxes, or shoe boxes. Ideally, you want a range of sizes, with at least one box being overly…

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.…
