Dog SNPs and Curly Hair
In an effort to add more real data to the DNA (genetics) unit, I added a shortened form of the HHMI activity: “Mapping Genes to Traits in Dogs Using SNPs” The activity on HHMI is too advanced for freshman level biology, but I thought it would be a good introduction to DNA sequences. The activity…

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…

Model the Digestive System with Coloring
The digestive system is a series of organs that work together to break down food into nutrients that the body can use. The digestive system includes the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. Coloring activities can be helpful to give students a chance to model the organ systems. I short, coloring…

DNA, Proteins, and Mutations
Students explore how DNA becomes a function protein by using a codon chart to transcribe and translate a gene. They compare the gene found in humans to that found in other animals, deducing that the genes are very similar with only slight changes. Finally, students examine the different types of mutations and how a…

Evolution: Fact, Fiction, or Opinion
This lesson can be used to introduce evolution and establish what your students already understand (or misunderstand) about evolutionary theory. Statements can be printed and cut into slips and students work in small groups to categorize each statement as either Fact, Fiction, or Opinion. The included answer key has quick explanations as well…

Concept Map on Blood
Students studying blood and the lymphatic students can get overwhelmed with the terminology used to describe blood and how blood is categorized. This project is designed to help students organize these difficult terms by creating a large concept map which groups related ideas together and connects them to other ideas – a concept map! …

Case Study: How to Survive a Cholera Epidemic
In this case, students explore how cholera is spread and how it affects the body. The case is divided into four sections, with the first part focusing on the role of clean water supplies and the spread of bacteria. In the second part, the affects of the bacteria are examined, with attention on how the…
