What do physicists and musicians have in common? A lot more than you might think. After first viewing a slide show presentation and completing a series of skills practice worksheets on the physics of light, sound, and...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

The lesson allows young scientists to use lasers and mirrors to study reflected light. A reading passage and homework question assess learning, while additional material introduces extension activities. 

Even the kindest friends can become selfish and tyrannical in Hans Christian Andersen's "The Snow Queen." Class members complete story-themed exercises in language arts, social studies, and even physical science.

Don't worry, optics is a light topic! The presentation covers reflection, refraction, fiber optics, mirages, prisms, rainbows, dispersion, mirrors, lenses, telescopes, diffraction, the human eye, and much, much more. Presentation is...

How does a telescope magnify images? Learners first watch a tutorial explaining the basic construction of a telescope. Then they interact with a simulation that allows for changes in the location and diameter of the reflecting mirrors....

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

This trigonometry textbook takes the learner from a basic understanding of angles and triangles through the use of polar coordinates on the complex plane. Written by a mathematician-engineer, examples and problems here are used to...

Understanding the ways a fire will act is a key factor in fire safety and fire prevention. Young campers focus on how the weather and terrain can affect the behavior of a fire with topographic maps and different...

Although their name makes them sound dangerous or toxic, carboxylic acids are found throughout nature in things such as citric acid, vinegar, and even in your DNA. Through detailed readings, discussions, and answering questions...

Lesson 19 in the series of 36 analyzes the element hydrogen and the s-block elements. Through readings, answering questions, and discussion, learners write about and explain their occurrence, physical and chemical properties, and...

An informative presentation covers motion, metric system, conversions, graphing of coordinates and lines, speed, velocity, and acceleration problems, as well as mean calculations. This is the first lesson in a 26-part series.

Saturn's rings are made of dust, ice, and solid chunks of material. Individuals use spectrographs in this final installment of 22 lessons to determine the atmospheric elements. They analyze spectrums from Titan's atmosphere and...

Space shuttles traveled around Earth at a speed of 17,500 miles per hour, way faster than trains, planes, or automobiles travel! In the 13th installment of 22, groups graph different speeds to show how quickly spacecraft move through...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...
