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. 

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...

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...

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...

Biogeography is the study of the geographical distribution of plants and animals. NOVA's Evolution Lab explains how organisms on different continents can be so closely related. The resource discusses the processes that bring life from...

Scientists learn about animals and plants living today by understanding the fossil record. A helpful resource includes a brief explanation of the process to help scholars complete the online game. It also mentions the gaps in knowledge...

Each branch of a phylogenetic represents a species, and you can trace each one back through history. A short video, the fourth of seven, introduces phylogenetic trees and the online game lab used in the unit. 

Are chickens and crocodiles really related? Young scientists compare the bone structure of current domestic chickens to other animals throughout evolution. This helps them understand the branches that separate crocodiles and birds as...

Need help putting together an uncommonly good unit about common ancestry? Check out a video that covers NGSS standard LS4A, Evidence of Common Ancestry and Diversity. Topics include ways to convey similarities and differences between...

Since its conception in the mid-1800s, the theory of evolution has been a point of hot discussion, but what exactly do the facts say? Take your life science class on an evolutionary exploration, analyzing the different pieces of evidence...

Help young biologists find their place in the animal kingdom with a life science presentation on the phylum chordata. Over the course of 54 slides, your class will dive deeper and deeper into the hierarchy of biological classification,...

Can an organism with no eyes still see? As it turns out for the purple sea urchin, the answer is yes. In a short video, scientists explain why they believe that some sea urchins can use their spikes to visually sense the environment.
