Virtual Diffusion Lab
The diffusion lab has been a yearly activity in my biology class as part of a unit on cells and cell transport. Students fill a bag with starch and water and then submerge it in a solution of iodine and observe what happens. The iodine diffuses across the plastic bag and turns the starch purple.…

Skeleton Label Using Slides
Many students in health, anatomy, and biology classes learn the bones of the skeleton. To introduce the topic with my anatomy students, I usually lay random bones on the tables. Students guess where the bone is found in the body. Some are easy, like the femur. The scapula usually stumps them. It can be a…

Niche Partitioning – Gorongosa Phenomenon
In order to convert my lectures to phenomenon-based lessons, I started the community interaction chapter with a mini-case about how animals on the savanna share one resource, grasses. The idea is that students would slowly build their understanding of how energy transfers through ecosystems and how populations within an area are limited by those resources. …

Ecology Lesson on Trophic Cascades
This year I decided to change the way I teach the last unit of the year, which is ecology. Our textbook is really old, and not aligned to NGSS. The lessons followed a familiar “old-school” pattern: take notes mainly about definitions, do an activity or lab, then take a quiz. This year, I wanted to…

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…

Introduction to the Light Microscope
Students learn to use a basic light microscope by examining the structures and using a prepared slide of the letter “e” to practice focusing.
