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…

Forensics Lab on Blood Spatter
Explore forensics with this lab on blood stain analysis. Use fake blood to determine how height affects the diameter of the stain

The Genetics of Frizzle Frazzle Chicks
Frizzle feathers in chickens is the result of a dominant allele. Practice crosses between different types of chickens, by completing Punnett squares.
-
Peas, Please! – A Practice Set on Mendelian Genetics
Students practice assigning genotypes (PP, Pp, or pp) to different traits based on whether the trait is dominant or recessive. They set up Punnett squares, and determine the phenotypic ratios of the offspring.
-
Label a Bacteria Cell
A short activity on bacteria cell form and function. Students label a diagram of a bacteria cell and answer questions.
-
What Causes Goosebumps? – Anatomy of Skin
Students label an image showing the cross section of skin. Text explains what each structure does and focuses on the phenomenon of goosebumps.
-
Brazilian Wasp Venom Kills Cancer Cells – CER
Students complete an CER on how Brazilian wasp venom can disrupt the cell membrane of cancer cells which can potentially be used to treat disease.

Genome Wide Association Studies in Dog Coats
Data examines single nucleotide polymorphisms (SNPs) that indicate a strong or weak correlation to coat length and texture in different dogs.

Practice Punnett Squares with Skinny Pigs
“Skinny Pig Genetics!” Hairlessness in guinea pigs is a recessive trait. Students practice Punnett squares with this simple worksheet.

DNA Lesson Using PTC as an Anchoring Phenomenon
Describes how using anchoring phenomenon can improve lessons on teaching DNA and how the sequence of DNA determines structure and function.

Learn the Anatomy of the Ear
In this activity, students learn about the ear by exploring google slides and going to an interactive site that explores how the ear works. Students use a simulation called “The Interactive Ear” which guides them though the outer, middle, and inner ear while explaining what each structure does. Students click through the virtual ear to…

Horse Genetics
Practice genetic crosses with horse traits. The gait-keeper gene controls whether a horse will trot or pace and the flaxen gene determines mane color.
-
StoryLab – Microscope “E”
This Storylab aligns with a basic microscope lab where students learn the parts of the microscope and locate the letter “e’ on a prepared slide.

Dihybrid Crosses in Guinea Pigs
Teaching dihybrid crosses can be challenging because it involves layering several biological concepts, like independent assortment and statistics. This worksheet illustrates how gametes are formed from the parents and used to create a 4×4 punnet square that is used in basic genetic problems.

Variations on a Human Face
Students use coins to simulate how alleles separate during meiosis. One student plays the father, and one plays the mother, a coin flip then determines the traits of their theoretical offspring. Note: This is a representation of how traits may work with simple Mendelian Genetics. Human traits are actually much more complicated. Many are…
