Introduces students in grades five through eight to key concepts in physics, focusing on gravity, using visuals and experiments to discuss mass, weight, distance, Galileo, air resistance, parachutes, terminal velocity, and G-force. Includes review segments.

Introduces students in grades five through eight to the properties of matter, such as color, shape, size, mass, weight, volume, and density; identifies the four phases of matter; and discusses the idea of chemical properties. Includes experiments and reviews.

Introduces students in grades five through eight to key concepts in physics, focusing on magnetism, using visuals and experiments to discuss poles, magnetic fields, domains, spinning atoms, the use of magnetism in music, compasses, and Earth's magnetic field. Includes review segments.

Introduces students in grades five through eight to key concepts in chemistry, focusing on the periodic table, using visuals and experiments to discuss atoms, elements, electrons, periods and groups, metals, metalloids, and nonmetals. Includes review segments.

Introduces students to key concepts in chemistry, focusing on atoms and molecules, using visuals and experiments to discuss the atom, electric charge, elements, the periodic table, chemical bonds, covalent bonding, ionic bonding, and phases of matter. Includes review segments.

Introduces students in grades five through eight to key concepts in physics, focusing on simple machines, using visuals and experiments to discuss work, forces, levers, the wheel and axle, pulleys, the inclined plane, and compound machines. Includes review segments.

An overview of light and the nature of light. Covers topics such as why light shines through (or reflects off of) some things but not others, how light travels and behaves, and concepts such as wavelength, amplitude and frequency.

Explores light and its properties such as wavelength, reflection and absorption.

Explores the properties of flight and aerodynamics, air pressure, and the work of Daniel Bernoulli.
