In this video segment adapted from ZOOM, cast members make a bridge from a single piece of paper. Will it be strong enough to hold a hundred pennies?

In this video produced for Teachers' Domain, Chi-An Wang, a mechanical engineering graduate from the Massachusetts Institute of Technology, describes her process when working with New Balance to design a new triathlon shoe.

This video defines energy, reviews a model of different types of energy and presents the four known stable global energy resources. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives and Activities.

This video takes an in-depth look at the annual energy available on earth against the amount of energy used by humans. It uses a graphic, published by Wes Hermann in the journal Energy, to makes clear the different energy fluxes. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives and Activities.

This video goes through the carbon cycle and describes how using fossil fuels threatens the foundation of the aquatic global food chain. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives and Activities.

This video describes in detail the greenhouse effect and how recovery from energy from fossile fuels results in green house gases. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives and Activities.

This video distinguishes between renewable and non-renewable energy resources. It examines the question, "How long to do we have before we exhaust non-renewable resources?" It also looks at alternatives to non-renewable energy resources. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation.

Each issue of the free, online magazine Beyond Weather and the Water Cycle explores an essential principle of climate science and climate literacy with background information, lessons, activities, original stories, and more for the K-5 classroom. This article shows the alignment of these materials with the content standards of the National Science Education Standards.

The evolution of ideas is often ignored in the teaching of statistics. It is important to show students how definitions and formulas evolve. This activity describes a fairly straightforward activity of how measures of association can evolve.

In this video segment adapted from FETCH!, contestants are challenged to use materials from a garbage dump to build a boat that floats, can be steered, and is propelled by something other than oars.

In this video segment adapted from NOVA, watch residents of the Peruvian Andes build a suspension bridge made entirely of grass. The ancient Inca were a textile society and thus skilled in working with natural fibers including alpaca and cotton. Still, it might surprise people today that their solution to crossing the canyons and gorges of their mountainous empire featured another fibrous material: grass. When you consider how they built a simple suspension bridge, you'll realize that not only was this a practical solution, it was also a safe one. In this video segment adapted from NOVA, watch residents of the Peruvian Andes as they build a traditional and functioning grass bridge the likes of which enabled the ancient Inca people to flourish for several hundred years. Grades 3-12.

In this video segment from PEEP and the Big Wide World, children experiment with cardboard and build a house for their stuffed animals.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water. This lab asks learners to record measurements and make calculations related to volume, diameter, area, and height. Learners also convert meters into nanometers. Includes teacher and student worksheets but lacks in depth procedure information. The author suggests educators search the web for more complete lab instructions.

This video segment adapted from FETCH! shows contestants experimenting with different materials to see which is the best insulator and thus best able to keep the lemonade at their stand cool for customers.

This article highlights resources that can be used to supplement lessons on extreme weather, including games and video clips. The article appears in the free, online magazine for K-Grade 5 teachers Beyond Weather and the Water Cycle. The magazine focuses on the essential principles of climate science.

Follow along in this video segment from ZOOM as 13-year-old Nick explains how he came up with a design, tested materials, and constructed his own cardboard chair.

This article gives background information on the Iditarod race in Alaska and shows how the race can be used in Grades K-5 classrooms to incorporate science, geography and language arts. The author provides links to resources that involve reading expository tests and writing assignments as well as working with real-time data. The article appears in the free, online magazine Beyond Penguins and Polar Bears.

This article describes daily life and work at the IceCube telescope at the South Pole, Antarctica, and links to informational text about them. Versions are available for students in grades K-1, 2-3 and 4-5. Related science and literacy activities are included.

How can you lift a heavy metal table using air? In this video segment adapted from ZOOM, cast members succeed in lifting a table using their own breath and a few plastic bags.

Repeated motion is present everywhere in nature. Learn how to 'make waves' with your own movements using a motion detector to plot your position as a function of time, and try to duplicate wave patterns presented in the activity. Investigate the concept of distance versus time graphs and see how your own movement can be represented on a graph.
