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. 

Can your class solve the Mystery of the Crooked Cell? Junior geneticists collaborate to learn about sickle cell anemia in a fascinating lesson plan. The included materials help them to examine the genetic factors behind the disease...

Scientists believe red hair and pale skin evolved in northern Europe because it helped humans synthesize vitamin D easier than those with more melanin in their skin. Viewers explore many interesting facets of evolution in a video all...

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,...

Sharpen up those scalpels, it's time to dissect some frogs! This step-by-step guide walks young biologists through this surgical process, helping them to identify major organs and unique anatomical characteristics of these amphibious...

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...

After watching an engaging 13-minute video about the colorless blood of icefish, future ichthyologists examine icefish blood and non-icefish blood (blood samples are simulated with Karo syrup mixtures) to determine advantages of...

Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

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.

Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....

With the forest as an example, Sam and Zoe talk about the components biotic and abiotic of an ecosystem. They also discuss the role of producers, consumers, and decomposers. This concise clip covers all of the basics. As an introduction...

Is there one right way to control infectious diseases? Learners determine the facts each stakeholder must consider when making their recommendations for controlling a disease threatening their area. They take into account public health,...

Don't just teach learners to fish, but to create fish. The class discusses fish heads and predicts whether where the fish might live and what it eats. Given an index card with a fish adaptation written on it, pupils construct an...

Am I going to catch it? Individuals time how long it takes them to walk, jog, and run a given distance and calculate their speed. They then research two animals and find their speeds. Using a chart, pupils compare the speeds of the...

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...

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...

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...

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...

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...

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...

Would you rather having biting flies or chocolate? The question may seem absurd, but cocoa trees rely on pollination from biting flies. Viewers come to understand the importance of pollinators to our food supply, flowers, and entire...
