Birds adapted to almost every climate on the planet, from the Arctic to the rain forests. A presentation focused on birds covers their similarities and differences. It starts with their evolution from reptiles, their many physical...

Can you move like a photon? Young scholars use a maze to reproduce the straight line motion of a photon. The second in a six-part series of lessons on the sun has learners measure angle of incidence and refraction to determine the path...

Young scholars recognize that a connection exists between an organism's physical and behavioral traits and its environment. They explore and define different types of interactions that can occur between organisms.

By choosing a species and researching an adaptive symbiotic relationship it shares with another species, your learners are able to investigate a symbiotic relationship in a lab setting. They create a presentation using a variety of...

When crocodiles close their mouths, you still see their teeth, but when alligators close their mouths, their teeth are hidden. Learn more about these reptiles and their many evolutionary cousins in a fact-filled presentation. It...

Illusions are what your mind makes them. Learners view several optical illusions. After each illusion the resource describes what is seen and the potential connection to evolution of the brain. Illusions include seeing different objects...

Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

Students research the evolution and cultural significance of the Arabic ghazal form of poetry. They, in groups, compose an original ghazal poem and read it aloud to the class.

Students explore natural selection. For this genetic adaptation lesson, students discover why certain traits continue and some traits disappear. Students discover how species evolve and change. Resources are provided.

Students create a dichotomous key. In this categorizing lesson, students create a dichotomous key for different types of cereal. Students classify the cereal into groups such as flakes and cereal with holes. Students discuss their...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

Scientists found fossils of plants more than 420 million years old—but plants existed for up to 100 million years prior to these fossils. Learn about the importance of plants to the entire planet. Viewing a presentation helps scholars...

How does the Earth continually repair itself? Explore the answer to this question, and others, with a unit on plate boundaries and interaction. Pupils classify the types of movement at plate boundaries and identify the...

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...

Students utilize the Internet and all its web access in this lesson. They research all they can on Evolution and related subjects. The journey they begin on leads them into an exhaustible point of possibilities for Evolution and all its...

Young scholars examine how all life is related and how species are classified. They also discover how traits are passed down from one person to the next. They examine the evolution the arthropod has going through.

Students illustrate the results of natural selection by identifying conditions that could lead to the development of new species (speciation) based on a given description of environmental conditions and description of variation within a...

When was the last time your class saw a catalyst in action? Chemistry scholars observe an activated complex during an engaging experiment. Through both color change and evolution of a gas, individuals gain insight into the...

Students identify the different taxonomic classifications of organisms. For this biology lesson, students create their own organisms and make some changes according to environmental conditions. They present their work in class.

Students estimate the number of living organisms they might find in their local environment. After researching the types of organisms that existed during various geologic time periods, students describe how life forms have changed over...

Students read a sample research proposal and create their own. They discover the type of information needed for others to reject or accept the proposal. They practice applying the scientific process to different situations.

The Milky Way gets great reviews on Trip Advisor — 100 million stars. The activity allows scholars to rethink their assumptions and prior knowledge. Pupils observe a set of two lights at equal distance and brightness, but they believe...

Hello? Hello? Scholars investigate the impact Alexander Graham Bell's telephone had on the American landscape. Using drawings, video clips, and primary sources, the mind of the inventor comes to light as pupils dream of new inventions to...

Teens experience natural selection firsthand (or first beak) in an activity that has them act as finches foraging for food. Using different household items  to act as different beak styles, your little finches will collect as much...
