It doesn't matter if you look on land, in the air, underground, or in water—evolution is everywhere. Scholars complete worksheets with multiple question types as they progress through six online missions creating phylogenic trees. 

Many scholars study phylogenetic trees without understanding how they are made. Through an online game, young scientists use the given data to create phylogenetic trees of increasing complexity. They rely on the trees they create to...

Geologists are gneiss, tuff, and a little bit wacke. The fifth chapter of seven includes ten activities at four different levels. The hands-on activities cover fossils including how they are formed, vertebrates, invertebrates,...

Why are there old dinosaur bones in the museum? Because they can't afford new ones! The chapter contains seven hands-on activities at four different levels covering geological eras, dinosaurs, timelines, and statigraphy. 

The featured movie focuses on the ancestry of our four-footed friends. Find the fundamental pattern of their limbs and vertebrae in fossils of fish. After viewing, biology learners can enjoy interactive websites to zoom in on the...

Different islands in the Caribbean have very similar species of anole lizards, which each have their own place in the ecosystem. Researchers did several studies to determine whether the anoles evolved into the different species then...

In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Are you having trouble deciphering the Next Generation Science Standards on the website, or just trying to find the standards for your grade in a quick-and-easy format? If so, here is a free and easy-to-navigate app made with you in mind.

A famous fossil of fighting dinosaurs holds as many questions as answers. Scholars first analyze the fossil itself by virtually highlighting the specific bones of the dinosaurs and read about their function and importance. They then test...

Some dinosaurs get all the attention. Pupils use an interactive resource to study some of the lesser-known dinosaur species. Organizing the information in a cladogram allows learners to make connections among the species.

Put all the pieces together. After a skeleton is put together, pupils play the scientist to determine the type of animal they have by using a classification tree to narrow down the identity. After each decision, they gain advice from an...

What's the most interesting fact about a blue whale? Learners read an interview about the similarities between the Titanosaur and the blue whale displays at the American Museum of Natural History. Pupils learn not only about blue whales...

Follow the path to the sea floor. Pupils play an online interactive board game to reach the bottom of the sea. Participants must match descriptions of creatures to a property of water dealing with oxygen, food, light, or density to move...

Explore a variety of science concepts in an interactive textbook created for middle school scholars. A lengthy table of contents takes readers to pages comprised of a subject overview, outline, and summary. Follow links further to find...

How have birds evolved from prehistoric animals? With the three-part lesson, small groups first research different prehistoric animals and determine whether they are birds. Then, scholars explore different bird adaptations using the Flap...

How are animals classified? Scholars explore animal classification by observing non-living and living specimens. They learn how to organize animals into vertebrates and invertebrates and identify the five vertebrate groups: mammals,...

What does it take to create a scientific theory? Learners attempt to answer the question by studying the work of Charles Darwin and Alfred Russel Wallace. While watching a video, they track observations from each scientist and then look...

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...

Scholars take off on an interactive spaceship to explore a historical timeline of the big bang theory. They learn about the evolution of mammals and humans, the formation of stars and planets, and the chemical composition of the early...

Which characteristics make organisms unique? Dichotomous keys simplify the process of classifying organisms by focusing on these unique characteristics. Young scholars learn how to use the dichotomous key flow chart by creating their own...

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...

Two scientists, two independent studies, two similar theories! A video lesson presents the work of Charles Darwin and Alfred Wallace that led to their theories on evolution. Scholars then evaluate statements and provide evidence to...

Are birds descendants of dinosaurs? Learners consider the question as they watch an informative video comparing fossil records of dinosaurs with current species. Following the video, groups ponder the evidence to draw conclusions about...
