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…

DNA, Proteins, and Sickle Cell
In this activity, students use a codon chart to compare the DNA sequence of HbA (normal hemoglobin) to HbS (sickle cell). The DNA differs in a single base, where the codon for normal hemoglobin codes for glutamine, and the mutant form codes for valine.

Genetic Crosses with 2 Traits with Rabbits
Beginning biology students can struggle with dihybrid crosses and setting up Punnett squares that have two traits. When tackling this concept, make sure students are familiar and competent with basic genetic crosses and setting up Punnett squares for a single trait. For example, a tall (Tt) plant is crossed with a short plant (tt). Once…

Sheep Heart Dissection
Students use this dissection guide to learn the anatomy of the heart, using a sheep as a model. The sheep heart is similar to a human, and students can identify the major vessels: aorta, pulmonary artery, pulmonary vein, and the vena cava. The guide includes instructions on how to determine which side of the heart…

Explore Anatomy – Color the Bones of the Hand
Learning anatomy can feel daunting, but there are plenty of ways to make it more engaging and interactive. One great way to help students understand the structure of the human hand is through a hands-on (pun intended!) coloring exercise. By coloring the bones of the hand, students can reinforce their understanding of how these structures…

Cell City
This popular activity asks students to read a story about a fictional town where each part of the city is compared to the parts of a cell. For example: “Widgets are generally produced in small shops around the city, these small shops can be built by the carpenter’s union (whose headquarters are in town hall.)” In this…

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…
