Biochemistry and Cell Signaling Pathway of the Mc1r Gene
How do mice have so much fur color variation over generations? Scholars illustrate protein structures based on amino acid sequences. Then, they analyze the signaling pathway in different-colored mice populations. This allows them to...
Howard Hughes Medical Institute
Color Variation Over Time in Rock Pocket Mouse Populations
While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

Molecular Genetics of Color Mutations in Rock Pocket Mice
Can you identify mutations just by viewing DNA sequences? Scholars apply prior knowledge of DNA sequences to do just that in an engaging activity. They transcribe and translate genes, thus identifying the locations of mutations. Then,...

What's This? Sensing
There is a scallop that relies on sight so much that it actually has more than 100 eyes! There are many species that rely heavily on one sense or another. An online interactive resource has youth read about several of these animals. The...

Why Don't Whales Have Legs?
Students are given a variety of materials and are asked to design a heat loss experiment that results in a reasonable explanation of "Why don't whales have legs?" students work with the theory of natural selection.

From Wolf to Dog
Students explain how dogs evolved from wolves based on the video. In this biology lesson, students research about breeding animals for specific traits. They interview dog owners and create a presentation about the dog.
Curated OER
Biology: Natural Selection
Students explore evolutionary processes and theories using the spotted fish applet. They observe what happens to fish in a closed environment with both food and predators. Students run the model several times and answer questions about...

13 Ways to Tell Time Backwards
Learners explore different ways geological time can be measured: comparing the time dimensions for each method, the mechanisms of each method, and the materials used.

Bermuda: Search for Deep Water Caves 2009: Out of Darkness
Students analyze the three models on the origin of troglobitic fauna. In this life science lesson, students also consider how the Zonation model explains the fauna's origin. They also use the Internet to research solutional and volcanic...

Comparative Embryology Using Japanese Medaka Fish
Students conduct an experiment to control the breeding of Japanese Medaka fish. They collect the fertilized eggs and view and record the fish's embryological development daily to compare the stages to human development.
Curated OER
Natural Selection in Action
Students demonstrate natural selection through a lab activity. In this biology instructional activity, students explain how natural selection leads to speciation. They complete their lab report and discuss results in class.

Dichotomous Key 2
Students use a dichotomous key to identify unknown fictitious organisms in an assessment designed to be used after a discussion on the use of a dichotomous keys has occurred. Follow up questions about key included.

Exploring Learned and Innate Behavior
Compare and contrast learned and innate behaviors between humans and primates. Your biology class members read articles and participate in discussions about the use of tools and communication methods. That's about it, you'll probably...

The Debate Over Teaching Intelligent Design
Students explain the current nationwide debate regarding the teaching of intelligent design alongside evolution in public schools. They examine the content of the debate and then analyze and critique the merits and flaws of both sides of...
Curated OER
The Crusty Fossils
Students identify some of the different species of crabs and tell how they adapt themselves to their environment. They discuss the evolution and stages of development of the crabs. They identify the Phylum Arthropoda and the Class...

Activity: Bird Beak Buffet
Students study the functions of bird beaks. In this animal evolution lesson, students compare and contrast different types of bird beaks focusing on how the beaks are adapted to the foods the birds eat. Students record and graph their...
