Ecological Succession Card Sort Activity
Ecological succession is a key idea in ecology that describes how ecosystems change and develop over time. It is the natural process where an ecosystem’s structure and species composition gradually shift, leading to the formation of a stable, mature community. This process involves a series of stages, each characterized by different types of species and…

Case Study – Carrying Capacity and Rabbits
Explore the factors driving the exponential growth of rabbit populations. Students learn about boom and bust cycles and carrying capacity in this case study.
-
Mitosis and Cancer – Data Analysis on Carcinogenesis
A group activity where students analyze images and charts to determine the relationship between mitosis and cancer.
-
Scary Pumpkin Statistics
Students predict the number of seeds in a pumpkin and then count the seeds. They use chi square analysis to accept or reject the null hypothesis.
-
Explore Limiting Factors and Carrying Capacity
Explore how limiting factors affect population growth. Students learn the definition of a limiting factor and apply it to several scenarios.

The Martian and the Car
This worksheet is one of the older ones in my collection, and was recently updated to include a Claim-Evidence-Reasoning section (instead of short response/essay). This a a great way to introduce the topic of life and how we define whether something is living or not. In this scenario, a Martian is observing earth and decides…

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…

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.…

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…

Macromolecules Lab – Testing for Starch
Most biology textbooks have a chapter on macromolecules. In chapter 2 of our textbook, students learn about the chemistry of life, which includes the basics of atoms and molecules, properties of water, and carbon compounds. I generally include a food testing lab where students determine the macromolecules found in food. The lesson is engaging, informative,…
