Endangered Species: What and Where?
What do endangered species have in common with non-endangered species? Given an endangered species to read about, individuals choose another species that is not endangered to compare it to. As a class, they create a species book with the...
National Wildlife Federation
Prairie Chicken Pageant
Diminishing habitats is a real concern that is threatening endangered species. Learners examine these concerns by studying the prairie chicken. Groups get a card with characteristics and threats to the species that they turn into skits.
National Wildlife Federation
Bird Behavior Hike
Bird behaviors have a distinct purpose. Using a tally sheet, learners observe and record different bird behaviors in nature. They practice their observation skills while learning how birds act and why.
National Wildlife Federation
Fill the Bill
The structure of a bird's beak lends itself to specific functions. Using an assortment of everyday objects, learners mimic the behaviors of bird beaks. They learn about the habits of different birds by studying their beaks.

Brown Pelicans
Even animals that are part of the same species have differences. Learners read a passage about white and brown pelicans and compare their features. They recognize that although the birds look very similar, they also have their own unique...

Icefish Blood Adaptations: Antifreeze Proteins
Ever wonder how fish survive in freezing cold water—especially Antarctic waters? Some fish have an adaptation that lowers the freezing point of their life fluids. Learners model these adaptations in two lab explorations. The first...

Color Variation Over Time in Rock Pocket Mouse Populations
Simple characteristic changes can have a significant impact on species survival. A hands-on activity has learners investigate the color variation in pocket mouse populations in different environments. They connect the timing and number...

Following the Trail of Evidence
One important skill in analyzing scientific evidence is identifying facts versus opinions. Scholars identify pieces of evidence from the film The Day the Mesozoic Died and then discuss this evidence in small groups at the end of each act...

Testing a Hypothesis
Are sickle cell disease and malaria related somehow? Scholars learn about both illnesses and the hypotheses that they are related. They discuss, view a video, and answer questions to demonstrate understanding. The resource includes an...

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...
Howard Hughes Medical Institute
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,...
Howard Hughes Medical Institute
Natural Selection and Evolution of Rock Pocket Mouse Populations
Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

The Molecular Evolution of Gene Birth and Death
More than 90 percent of humans' DNA doesn't code for anything! Scholars watch a presentation as they answer questions relating to gene mutations. They read details, watch videos, and view animations supporting the concepts. The questions...
Howard Hughes Medical Institute
Icefish Blood Adaptations: Viscosity
Most fish freeze to death when the water is too cold, yet some fish live in the Southern Ocean where the water is often below freezing. Scholars use two models representing the blood from most fish versus the blood from Antarctic fish....

How Do Fibers Form?
The proteins inside a cell determine the shape of the cell. While most red blood cells have a circular shape, those with sickle cell take the shape of a sickle. This change in shape causes multiple issues in the system. Scholars solve...
Howard Hughes Medical Institute
Population Genetics, Selection, and Evolution
The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

Weighing the Evidence for a Mass Extinction Part 2: On Land
What can fossils tell us about periods of extinction? Young scholars interpret fossil layers to make conclusions about changes in life during different geological time periods. They analyze the fossils for abundance and diversity as well...

Evolution of Fur Color in Mice – Mutation, Environment and Natural Selection
Most species of animals include a variety of fur or hair color, but why? Scholars watch a video about a changing environment for mice. As the rocks around them change hues, different colors of mice begin to thrive. Discussion questions...

Using Molecular and Evolutionary Biology to Understand HIV/AIDS and Treatment
HIV mutates rapidly, making treatments challenging to find. Scholars learn about why it mutates so quickly and how scientists race to find treatments. The resource approaches the issue from both a molecular and evolutionary perspective...

Beaks as Tools: Selective Advantage in Changing Environments
How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available....

Using DNA to Explore Lizard Phylogeny
On the Caribbean islands, lizards expanded into different niches instead of competing for resources. Scholars discuss and learn from experts in a video how scientists prove the theory. They build phylogenetic trees based on appearances...
Howard Hughes Medical Institute
Evolution in Action: Data Analysis
An environmental factor, such as a drought, sometimes speeds up the rate of natural selection. Scholars analyze data on the beaks of birds around the time of the drought. They compare those that survived to those that perished and find...

Lactose Intolerance: Fact or Fiction
Around the world, about 2/3 of adult humans are lactose intolerant. Scholars work in small groups to discuss a few statements about lactose intolerance. Then, they watch a video on the topic and readdress each statement. Whole-class...
