If you are looking for a great way to present natural selection in humans, look no further. This handout is intended to accompany the 14-minute video The Making of the Fittest: Natural Selection in Humans, which can be found on the...

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...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Most drugs used today come from nature, so the discovery of new ecosystems in the deep sea is exciting from a medical perspective. Scholars develop their own bioassay to test germination rates in seeds. 

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

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...

Areas that previously included no risk of Lyme disease now have cases every year. Scholars learn about the spread of Lyme disease and the relationship with ecological succession. Then, they discuss possible solutions using the known food...

Research patterns in nature which illustrate biological and mathematical concepts. Your class will discover and explore aspects of fractals, Fibonaccis numbers, whale and butterfly migration patterns, whale identification, flower...

One of the most striking pieces of evidence for Darwin's Evolution of Species was his observations of finches and how their beaks differed from island to island, depending on their primary food sources. So what would happen to the theory...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of...

Feast on an informative resource. Scholars learn about food chains and food webs and how these interactions give information about the natural community. A PowerPoint presentation provides information about this concept.

Searching for the perfect indoor/outdoor activity that allows class members the opportunity to learn about organism classification? Here, pupils research organisms and categorize them according to domain and kingdom over the course...

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Students identify the different biotic and abiotic components of an ecosystem. In this ecology instructional activity, students perform a case study on current environmental problems. They write a position statement about their chosen...

Young scholars view video showing recent field work on a twenty two-year study of finch beaks on a small island in the Galapagos, showing natural selection clearly operating in the wild.

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

Can your class correctly classify plant species? Individuals explore native plants of the local environment and correctly classify them into their respective categories. They investigate differences in the plants and discuss similarities...

High schoolers may claim to have no interest in scientific revelations and discoveries, but watch how quickly they download a new app onto their state-of-the-art smartphones. Scholars discuss the scientific or technological...

Discover how copying nature can be beneficial to humans. Scholars read articles about examples of biomimicry and its potential applications. Along the way, they learn about Nature's Nine Laws and how they relate to biomimicry. This is...

Does the early bird really get the worm? If so, which color of worm does it prefer? In an exciting and easy week-long field investigation, young field biologists set up a one square meter feeding area for birds. If you have a webcam,...

How do genetic mutations within a population lead to future variations? Provide your class with the resources to answer this question and more upon completing an activity on natural selection. The entire class participates in a...

Take learning outside and start classifying grasslands. Young ecologists observe grassland plants in order to classify them into the appropriate species by family. They note their characteristics and where they grow. A true...

Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...
