In this video segment, the ZOOM cast is challenged to keep a ping pong ball in a funnel while the funnel is held upside down, seemingly defying gravity.
Why does an egg float in salt water? Learn about density and buoyancy in this video segment adapted from ZOOM.
Watch warm water float on top of cold water in this video segment adapted from ZOOM.
This video segment adapted from ZOOM offers a clever demonstration of buoyancy by showing how to pour a cup of air into a cup filled with water.
Will a grape float in oil? Will a metal nut sink in corn syrup? Watch as the ZOOM cast tests the buoyancy of a variety of liquids and objects.
This lesson plan utilizes the Describe App to solidify student speech sound productions. While the plan is tied to all grade Speaking and Listening by responding to questions using a clearly stated response which is found across all the grade language arts standards, it can be adapted to meet any Speaking and Listening standard at any grade level, particularly in upper elementary, school based on the amount of support given by the clinician to support the sound producitons, clarify clues given, and the contextual clues discussed to support the student's ability to respond clearly.S(This resource's preview image was created by the author of this lesson plan.)
In this video from NOVA scienceNOW, learn how scientists detect potential signs of life on distant planets.
In this animation produced by WGBH and Digizyme, Inc., see how molecules of DNA are separated using gel electrophoresis, and how this process enables scientists to compare the molecular variations of two or more DNA samples.
How much radiation are we exposed to every day? Find out in this video segment adapted from FRONTLINE.
In this video from Evolution, an exploration of multi-drug resistant tuberculosis in the Russian prison system highlights one reason it is important to understand evolution.
In this video segment adapted from ZOOM, the cast investigates how the pitch of sound changes when they strike a variety of glasses filled with different amounts and types of liquids.
This activity gives students a way to look at how organisms are connected to ecosystems through the cycling of matter and the flow of energy. By the end of the activity, students will be able to make distinctions between how matter and energy are used and transferred and will be encouraged to apply this important crosscutting concept to the world around them.
First, students observe an animal, then they reflect on how it uses matter from food to build body structures and energy from food to do things. Students look at food as “packages” of matter and energy that animals (and plants) consume. They also think about wastes, such as poo, pee, sweat, heat, and carbon dioxide. This is a focused activity best used as part of an extended matter and energy-themed experience, and it works best after students have had time to explore, check out organisms in other ways, and be physically active.
In this video segment adapted from NOVA scienceNOW, hydrogen fuel cell cars promise pollution-free driving, but will we see them anytime soon?
Just after World War II, nuclear scientists turned their attention from fission to fusion. This video segment adapted from AMERICAN EXPERIENCE looks at the beginnings of thermonuclear power generation.
Learn how scientists regulate a nuclear reactor in this animation-enhanced essay from the FRONTLINE Web site.
Is the hydrogen car the answer to global warming? This video segment adapted from NOVA/FRONTLINE looks at the pros and cons of this developing technology.
This video segment adapted from NOVA/FRONTLINE examines the greenhouse effect, its role in keeping Earth habitable, and the industrial changes that have led to an increase in the planet's average temperature.
Metals are grouped according to their characteristics. This video segment uses the periodic table for an in-depth discussion.
In this video adapted from the National Science Center, observe a demonstration to discover how helium gas is inert and hydrogen gas is reactive.
