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.

Today's emphasis on the artificial and natural ingredients of the foods that we eat has placed new emphasis on the chemical composition of that food. Examine the chemical, nature of many familiar food products. Experiments in this module: Presence of sugars, starches, fats and proteins, fruit discoloration, chemical composition of milk, presence of iodine in salt, calcium propionate in bread and the qualitative test for vitamin C and sulfur dioxide.

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.
