power (mechanics)

Introduces the scientific concepts of energy and movement by using examples from everyday life.

Introduces forms of movement in nature and industry, discussing such sources of power as gravity, electricity, motors, and wind.

Presents experiments for exploring ways of harnessing and using energy.

Reviews the history of power and energy inventions, from the dawn of civilization to the present, including the first machines, steam and electric engines, and the incandescent light bulb.

An exploration of kinetic energy that discusses the energy of motion, atoms, waves, light, and global catastrophes. Includes a glossary and a list of resources.

Through simple experiments, readers learn about the properties of energy.

Explains what energy is, where the energy we use comes from, and why it is important to conserve energy.

The scientific concept of force is taught through text and step-by-step experiments.

Collection of projects students can make to help them learn about science. Subjects include mechanics, air power, electricity and magnetism, chemistry, acoustics, and optics.

Text and experiments demonstrate the nature and uses of energy in its various forms.
