Exploring Phenotypic Plasticity in Arctic Foxes
Learn about arctic foxes and how they change color in the summer, a phenomenon called phenotypic plasticity.
-
Compare Body Plans of Protostomes to Deuterostomes
Compare protostomes to deuterostomes, including details on the development of the blastula. Questions rely on students carefully examining the graphic.

Explore Bunny Selection and Mutations with PHET
Students explore bunny selection with this PHET interactive activity. Observe bunny populations change in response to environmental conditions and predators.
-
Mutations and Evolution in Aquatic Mammals
Students examine a phylogenetic tree that reveals mutations found in aquatic mammals as evidence of convergent evolution.

Case Study – Tibetans and Altitude (Remote)
This case study is a remote alternative to “How Do Tibetans Survive High Altitudes.” The remove version is shorter and does not require as much guidance by the instructor. I created this version with Google slides, so students can type their answers directly onto the slide. I made remote versions of several activities because I…

Speciation on Daphne Major – Big Birds Get No Love
The beaks of finches on the island changed in size after a catastrophic draught. Students analyze graphs and explore how natural selection affects populations.
-
Speciation Modes – Reinforcement
Students distinguish between allopatric and sympatric speciation and then identify what types of isolating mechanisms are described in scenarios.

Population Genetics in a Fishbowl
Students learn about Hardy-Weinberg equilibrium by exploring a virtual population of koi fish. This virtual lab allows students to run experiments where they can change variables, like population size, migration rate, mutation rate, and fitness of two separate alleles. The alleles being studied control the coloration of the fish. Fish can either be white, gold,…
