There are almost as many types of bird beaks as there are types of food that birds like to eat. This collection of images shows a wide range of beaks and the types of foods handled by each.

In this Nature video, learn about the extraordinary impact that birds have on the agriculture of a small Indian community.

This lesson plan incorporates many subjects! Students create a flow chart after studying the "Evolution," of computers. Also provides adaptations and references to use. (To access this lesson plan, you must register with Crayola.com. Registration is free and takes only a few moments to complete.)

This site is a lesson plan that incorporates language arts, social studies, science, and art. After studying islands, and how they're formed, students create their own models using clay. Also provides resources and adaptations. (To access this lesson plan, you must register with Crayola.com. Registration is free and takes only a few moments to complete.)

In this video adapted from NASA, two members of a NASA research team working to produce carbon nanotubes share some background behind this new technology, show examples of how it will be useful, and explain the various tests being performed to ensure readiness for spaceflight.

Lesson 4 is a step-by-step guide for the classroom which focuses on exploring and acknowledging the presence of Black people in the future and in space-related fields. It starts with students reading and discussing an interview with Samuel R. Delany. Then, students view a Black Futures artwork and information about Black astronauts, reflecting on the implications and spaces where they would like to see Black people fully represented. The lesson concludes with a design challenge task to make the best spaceship, either out of origami or recyclable trash. There is a recommended work time of 20+ minutes for building the spaceships, and students can submit their work for publishing on Instagram or email. The lesson is part of the #Kinfolk and #BlackFutures campaigns.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Augmented Reality, Internet Connectivity, Laptop/Desktop, Smartphone, Tablet, Tablet or Smartphone.

In this video segment, adapted from NOVA, Dr. Judah Folkman uses the scientific method to discover how cancer cells induce the formation of new blood vessels, which in turn nourish those cancer cells.

Throughout the day, your nervous system monitors and makes endless adjustments to your body's basic systems -- all to keep you alive. This interactive feature illustrates the complexity of such a task.

This video segment, adapted from NOVA scienceNOW, presents basic concepts of physics behind booming sand dunes. See how surface tension affects potential and kinetic energy and how it all works together to create sound.

See how plants make the world better (and the career lab a little bit happier) as you learn about rewarding careers in plant science.

In this video, Paul Andersen explains how a spectrometer was used to identify the presence of isotopes. This modified Dalton's original atomic theory because atoms of the same element had different masses. The functional parts of a mass spectrometer are detailed including the ionizer, mass analyzer and the detector. [8:19]

Paul Andersen outlines the AP Environmental Science course through a video, concept map, and slideshow. He explains how environmental science studies the interaction between earth and human systems. A planetary boundary model is used to explain the importance of sustainability. The importance of science practices and knowledge of the APES format is also included. [9:08]

Find out how serious head concussions can be in this video segment adapted from NOVA scienceNOW.

This video segment from The Human Spark observes the brains responses to a series of cognitive tests.

In this demonstration of chemical change, the presenter blows breath into a methylene blue solution releasing carbon dioxide which acidifies the water and changes it from a bright blue color to green.

In this interactive activity from the Building Big Web site, use your knowledge of bridge design to match the right bridge to the right location in a fictitious city.

See how a place-based high school curriculum project promotes STEM learning through local ethnography and conservation projects. This video segment showcases one of 11 CREST projects taking place in rural, coastal Maine communities. [5:40]

In this video segment adapted from A Science Odyssey, learn about bubonic plague and how city officials in San Francisco tried to contain its spread in the early 1900s..

In this interactive activity from Shedd Aquarium, build a fish and then release it into the reef to search for food and evade predators. Try different combinations and observe how each kind of fish has unique adaptations that help it survive in its habitat.

In this video segment adapted from ZOOM, the cast shows how the 34 steps in their Rube Goldberg invention use everything from gravity to carbon dioxide gas in order to accomplish one simple task: pouring a glass of milk.
