Electromagnetic Induction

Loading...
Demonstrations prove that when two coils are placed near each other, any change in the flow of electric current in the primary coil will induce a current in the secondary coil. Experiments explore the factors that increase the induced current, illustrating the relationship between the number of rings in a coil and the ratio of voltage applied to the amount of electricity induced.

Direct & Alternating Current

Loading...
Two neon lamps, one connected to a battery and the other connected to an alternating current power source, are employed to demonstrate the difference between direct current (DC) and alternating current (AC). A selenium rectifier is used to change AC to DC and to set a model car in motion.

Magnetism & Electricity: Practical Applications

Loading...
Several experiments conducted within a one-cubic-meter magnetic field produced by a powerful magnet explain the forces operating when an electric current flows through a magnetic field.

Dry Cell Batteries & Light Bulbs

Loading...
Experiments with light bulbs demonstrate the existence of positive and negative terminals in dry cell batteries. Comparisons are made between the output of one or more battereies, and batteries connected in series and in parallel. Also illustrated is the principle that when an electric current is produced, heat is also produced.

Creating Magnetic Force

Loading...
A series of experiments demonstrates that magnetic force is created when electricity flows. Therefore, a compass can be used to indicate if current is flowing through a wire; the compass can also indicate the direction of the flow of current. Experiments in this program also prove that a wire acts like a magnet when electric current is flowing through it.

Bipolarity

Loading...
The basic characteristics of magnetic poles are demonstrated in this program. Several experiments are performed with red and blue bar magnets with clearly identified poles. A concluding experiment carried out with a donut-shaped ring magnet emphasizes the nature of magnets and the property of bipolarity.

The Generation of Current

Loading...
Thin, freely moving iron needles are placed on a panel between the north and south poles of a powerful magnet; the magnetic field is clearly apparent. When a copper wire breaks the lines of magnetic force, an electric current is generated in the wire. Model cars illustrate that when a magnet is placed so that a revolving coil interrupts the magnetic field, a current is generated.

The Magnet as Compass Needle

Loading...
A compass needle acts as does an ordinary magnet, aligning itself north/south. One of the experiments performed in this program demonstrates how to make a compass needle. Demonstrations also include the north/south alignment of a bar magnet floating in a tank of water, the proper use of a compass needle and the accurate reading of a ship's compass.

Resistance

Loading...
Experiments presented in this program demonstrate the relationship between current and resistance, and between the length and/or the thickness of a wire and the amount of resistance. An electric toy trolley illustrates a practical application of the principle of resistance.

About Time [electronic resource]

What is time? Did it have a beginning? Will it ever end? Is it something that humans have created, or does it exist independently of the universe? This intriguing program explores the meaning of time through the eyes of poets, philosophers, and scientists throughout the ages. In addition, it traces the development of time-measuring and time-keeping instruments, from sundials and calendars, to time zones and atomic clocks.

Numbers, Units, Scalars, and Vectors [electronic resource]

Even Deedee Dodobird knows that a strong general knowledge of scientific and mathematical concepts makes it much easier to understand physics, the study of how things work. Section one of this program demonstrates fundamental abilities such as how to manipulate numbers using scientific notation and how to convert and algebraically cancel SI units. In section two, scalars and vectors are presented, including the head-to-tail and component methods of vector addition, dot products and cross products, and even a healthy dose of trigonometry.

Science and Gender [electronic resource]: Evelyn Fox Keller

When in the 1950s Evelyn Fox Keller ventured forth to become a scientist, she discovered it was a man's world. Training as a theoretical physicist and working in both mathematical biology and the history of science, she wondered why most scientists were men and why the language of science reflected masculine metaphors and values. Keller has grappled with the meaning and consequences of these stereotypes ever since. In this program with Bill Moyers, Keller discusses how gender plays a significant role in the language that scientists use to describe their work.

Science Lab Safety [electronic resource]

Many students do not realize how hazardous the lab can be. Safety awareness in the laboratory is essential. This engaging and entertaining program teaches students how to recognize hazards, prevent accidents, and cope with emergencies. The proper way to extinguish a fire is demonstrated, along with first aid for acid burns and electric shock.
