What Is Radioactivity?

Four activities demonstrate the chain reaction of nuclear fission to your physical science fans: falling dominoes, snapping mouse traps, throwing paper wads, and igniting a series of matches. They perform additional...

The physics department at The University of Hawaii has designed midterm exams for their college physics courses. This version deals with electricity concepts. It requires learners to calculate conversions, capacitance, and potential...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

Radioactive pollutants can enter the body through ingestion, inhalation, absorption, or injection. The last lesson in a series of 36 introduces pupils to radioactive pollution. They study its sources, both natural and man-made, its...

Ideal for your electricity unit, especially with middle schoolers, this lesson plan gets engineers using multimeters in electrical circuits to explore the relationships among voltage, current, and resistance. Older learners may even plot...

Does the mention of proteins and polypeptide relationships in your classroom result in mass confusion? Does the attempt to teach this important concept generate multiple questions and, at times, lead to a room filled with blank...

Make your lesson plan on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms....

Electrical current going round and round,produces a magnetic field. After a demonstration of the magnetic field surrounding an electrical wire, class members use the provided formula associated with Biot-Savart's Law to calculate the...

Students investigae using radioactive decay to determine geologic age.

Eddy currents, Faraday's Law and Lenz's Law provide the connection between train brakes and and MRI machines in a lesson that asks teachers to provided the material needed so the pupils can understand the properties of changing magnetic...
