By providing a variety of strategies, scenarios, examples of student writing, classroom video clips from across all science content areas, rubrics, and guidelines for designing assessment items, "Supporting Grade 5-8 Students in Constructing Explanations in Science: The Claim, Evidence, and Reasoning Framework for Talk and Writing" provides…

While researchers have documented the promise of detracking reform, many teachers still find it difficult to teach students with a wide range of academic skills in one classroom. Through engaging classroom footage and powerful interviews with teachers, students, and administrators, this 80-minute DVD showcases best practices from successful…

Proven through more than a decade of rigorous research to be effective with both teachers and students, "Making Sense of SCIENCE" helps teachers gain a deep and enduring understanding of tricky science topics, think and reason scientifically, and support content literacy in science, thereby increasing student achievement. The materials…

Sound. Light. Heat. Even earthquakes! They all travel in waves. Waves are a transfer of energy and understanding them allows us to better understand the world around us. Discover the two ways in which waves move, and learn about the characteristics of waves; wavelength, amplitude and frequency. Students learn about the common characteristics of…

This 23-minute videotape gives children (grades K-4) a close-up look at what makes the third planet from the sun so special. The answers to the following questions are discussed: (1) Why is there life on Earth? (2) What is our planet made of? and (3) How does the Earth fit into the rest of the universe? A hands-on activity that describes how to…

How different would life be without electricity? Creating and harnessing electricity has become one of the most important factors in the everyday lives of people. Children learn the basics of electrical current--how it flows and how it can make a circuit--and take a look at some of the ways it is created. Students will see fun, clear…

All kids know the word "work." But they probably don't understand that work happens whenever a force is used to move something--whether it's lifting a heavy object or playing on a see-saw. All About Simple Machines introduces kids to the concepts of forces, work and how machines are used to make work easier. Six simple machines are…

In All About Solids, Liquids and Gases, young students will be introduced to the three common forms of matter. They'll learn that all things are made up of tiny particles called atoms and that the movement of these particles determines the form that matter takes. In solids, the particles are packed tightly together and move very little. The…

Kids know that when they are lost, they look at a map to find their way. It's no different in the world of science, as they'll learn in The Periodic Table--a fun and engaging look at the road map of the elements. Young students will learn about key information included on the table, including atomic number, atomic mass and chemical symbol. They'll…

Most people think friction is what happens when two things are rubbed together. But there's so much more! Friction is a force that resists motion. Yet, without friction, motion would be impossible. Students will learn more about this natural force and the attempts made at controlling it in the world. Includes a hands-on activity and graphic…

There are more than 20 million known substances in the universe, and they are all made of the same basic ingredients--atoms and molecules. In this fun and engaging program, kids will learn about the three main subatomic particles--protons, neutrons and electrons--as well as the forces that keep atoms and molecules together. They'll discover how…

Most people know that the flip of a switch will power up toys, appliances and lights with electricity and enable them to work. But why? What is it about electricity that makes it so powerful and so dangerous? Students will learn the basic concepts of positive and negative charges, current flow and open/closed circuits, and discover why getting a…

In today's world, kids are aware that there are machines all around them. What they may not realize is that the function of all machines is to make work easier in some way. Simple Machines uses engaging visuals and colorful graphics to explain the concept of work and how humans use certain basic tools to help get work done. Students will learn…

A door closes. A horn beeps. A crowd roars. Sound waves travel outward in all directions from the source. They can all be heard, but how? Did they travel directly to the ears? Perhaps they bounced off another object first or traveled through a different medium, changing speed along the way. Students learn how sound waves travel and about their…
