Atoms & Molecules (DVD)
Atoms & Molecules (DVD)
D055

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 atoms bond to one another to form compounds. Ionic bonds are formed when electrons are transferred from one atom to another, while covalent bonds occur when atoms share electrons. Colorful graphics and fun visuals bring these concepts to life and make them easier for kids to understand. Includes a fun, hands-on activity that allows kids to simulate the movement of atoms and molecules in different phases of matter. This program is based on the concepts outlined in the National Science Education Standards for Physical Science: properties and changes in properties of matter, motions and forces and transfer of energy. Part of the Physical Science in Action DVD Series. A teacher's guide is available online. 23 minutes. Grades 5 to 8.

Sound (DVD)
Sound (DVD)
D070

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 as well as about their properties, frequency, wavelength, amplitude and pitch. With a fun hands-on activity, this program illustrates the key concepts of sound and its properties. One of 16 volumes in the Physical Science in Action DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title correlates to the National Science Education Standards for Physical Science -- properties and changes of properties in matter, motions and forces and transfer of energy.

Gravity (DVD)
Gravity (DVD)
D063

All kids are familiar with the basic idea of gravity -- it's why things fall to the ground. Gravity uses exciting visuals and clear, colorful graphics to take students beyond the basics to explain that gravity is really a force of attraction between objects. They'll discover that all objects -- no matter how large or small -- have gravitational force, and that the amount of that force depends on the mass of the distance between them. The contributions of Newton and Galileo are discussed, and gravity's connection with weight, orbits, acceleration and terminal velocity is explored. Includes lots of real-life demonstrations and a fun, hands-on activity that re-creates Galileo's famous experiment, which proved that all objects fall to the ground at the same rate, regardless of their mass. This program is based on the concepts outlined in the National Science Education Standards for Physical Science: properties and changes in properties of matter, motions and forces and transfer of energy.

Flight (DVD)
Flight (DVD)
D060

For thousands of years, humans dreamed of flying -- but it isn't as easy as birds make it look. Students will learn about lift, gravity, thrust and drag -- the forces that are used to get tons of steel off the ground and carry people thousands of miles before landing safely. They will also discover the role atoms and air pressure play in this amazing task as well as in other forms of flight. An interesting hands-on activity is included along with fun, real-life demonstrations to further illustrate these concepts.

All About Waves (DVD)
All About Waves (DVD)
D054

Sound, light, heat and even earthquakes travel in waves. Waves are a transfer of energy, and understanding them allows us to better understand the world around us. Students learn about the common characteristics of waves through real-life examples and clearly illustrated graphics. A fun, hands-on activity will help students understand these basic concepts. This program is one of 11 volumes in the Physical Science for Children DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library for Children Collection. This title correlates to the National Science Education Standards for Physical Science -- properties of objects and materials, position and motion of objects and light, heat, electricity and magnetism.

Fountain Connection - Clearance
Fountain Connection - Clearance
13452

Hero of Alexandria (c. 62 A.D) designed a water fountain that used compressed air to lift water to a point higher than its origin. Using your own soda bottles and this device, you can demonstrate the same principle. Water leaving the upper bottle creates a partial vacuum and enters the lower bottle compressing the air there. To balance out the pressure, air flows from the lower bottle to the upper bottle. The result is a spurting bubbling fountain that forms every time you turn this demonstration over. Additional experiments are suggested.

In this program, students will study both phenomena from their development to the full-blown storms that wreak havoc on land. Through satellite images, Doppler radar, graphics and storm footage, this program shows how meteorologists and "storm chasers" use data such as location, movement, wind speed, temperature and air pressure to predict the course of these storms, and provide early warnings to people living in their path. In a hands-on experiment, students will re-create the circular pattern of a tornado's vortex to further illustrate these concepts.
