Introduce your students to the fundamentals of chemistry. Provide your class with a basic understanding of the primary concepts of chemistry as they investigate how matter is classified, identify the various types of mixtures, and compare the properties of solutions with the properties for mixtures. They'll also learn to identify elements and compounds and study how chemical symbols, formulas and equations are used to describe chemical reactions. Grades 7-10.
Wide-mouth, conical flask made of polypropylene. Comes with a screw cap, or can be used with a stopper. Chemical resistant, and autoclavable to 135º C. Graduated in easy to see green print. Sold in packs of 12.

Our light comes standard with all of the features that you would pay more for on competitive lights. Features such as a photocell which automatically turns the light off when the surrounding light conditions make the light ineffective... Sunny daylight hours are an excellent example of this. This feature greatly extends the life of the batteries as the light only operates when it can be seen. Increased battery life not only saves you money on batteries, but on the labor required to service the light as well. Another key feature is our 3-Way Switch. This switch allows a single light to serve two purposes. Each of our lights operates in either flashing or steady-burn modes. It only takes a simple turn of the switch to change the personality of our lights. Another cost- saving feature is that our light will accept batteries in any orientation as long as the springs are pointing up. There is no need to wonder if the battery is positioned properly, there will be no more batteries thrown out because it was thought that they were bad, when the real problem was the battery turned in the wrong direction. Compare our light to the competition and you will see that we out-shine them every time. Battery not included.

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. 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 in properties of matter, motions and forces and transfer of energy. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.

Fossil fuels were formed millions of years ago as part of a natural process in which the remains of dead plants and animals were buried and placed under extreme pressure and heat. Coal, oil and natural gas are the most important fossil fuels. But what are they used for, how do we find them and what can we do to preserve our limited supplies? Students will find the answers to these questions and more in Fossil Fuels as they explore these nonrenewable resources of Earth. A fun, hands-on investigation demonstrates a creative alternative to using fossil fuels in the creation of plastic and a visit to an oil platform showcases how this valuable fossil fuel is pumped up from the bottom of the ocean. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Fossils are historic blueprints -- remnants of plant and animal life that preceded us. In Fossils, students will examine molds, casts and imprints of various living things, and discover how scientists place the age of these ancient remains and the methods they use to preserve them for future generations. Find out how paleontologists discover fossils and what these discoveries tell us about the past. Take a trip to the Petrified Forest, and examine tree trunks that were turned to stone millions of years ago. A fun, hands-on investigation demonstrates for students how they can create four different simulated environments in order to test each for its ability to preserve remains.
