Radioactivity and nuclear chemistry, transmutation of elements and isotopes, calculating half lives and radioactive decay. Introduce these concept and more with a video on carbon dating. The show concludes with an explanation of...

Young scholars discuss how small they must cut something before it is no longer fundamentally the same. An online activity challenges and engages pupils in learning about the periodic table. Two hands-on activities cover elements and...

Toss 100 pennies (or poker chips or any other two-different-sided objects) and remove all of those displaying tails. Line them up and repeat. The lines of pennies collected get smaller each time, successfully representing half-life.

Students simulate radioactive decay and nuclear power using an on line interactive web site. In this on line lesson plan, students monitor radioactive isotopes and record the activity of a particular element as the decay progresses. They...

How has Earth changed over time? Pupils explore the topic in a differentiated instruction unit on the geological time scale. After a pre-assessment to gauge knowledge, class members divide into groups based on their ability levels and...

Some 4.565 billion candles would be needed for a birthday cake for Earth. Young scientists view a video to learn about historical attempts to determine the age of Earth. They see how advances in radioactive dating led to the currently...

How do medical professionals use radiation without doing more harm than good? Budding nuclear chemists begin their study of all things radioactive with a video from the JFR Science playlist. Topics include differences between isotopes,...

Take a trip back in time as the history of the earth is uncovered. An interesting video lesson explains the different methods scientists use to learn about the earth's past. While emphasizing teaching strategies, the lesson instructor...

Need some strategies for teaching nuclear processes that are sure to cause an explosion of learning in your classroom? Get all the essential background knowledge, plus tips for getting your point across in a thoughtful video. Concept...

Explore the science of radioactivity! A very thorough video lesson begins with an explanation of the chemical structure of radiation. It includes descriptions of benefits of radioactivity and half-life calculations.

The earth is literally older than dirt, but how can we prove it? The video explains the methods used to find the age of the moon and the earth. It offers a quick overview of the rock cycle, geologic processes, and the impact of meteors. 

What makes some elements stable and others radioactive? Scholars adjust the number of protons and neutrons in an element then observe its decay. The simulation includes a graphical representation and the chemical formula, as well as...

Engineering challenges, construction costs, and disasters are some of the challenges when it comes to nuclear energy. Watch a video that explains each of these and more in detail.

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...

There are different types of radioactive decay, and alpha decay is when there are too many protons in a nucleus. Here is a simulation that shows alpha particles being emitted from a polonium nucleus. Learners see how radioactive decay...

Why does radiation occur? Learn the reason and the main types of radiation during this video lesson. Scholars discover the makeup of a radioactive atom and the effect of the different types of radiation. They then analyze and create...

Who receives that greatest amount of radioactive exposure? After visiting some of the most radioactive places on earth, including Chernobyl and Fukushima, viewers consider the exposure of radiation workers, astronauts, and cancer...

Which bichemicals wash up on shore? Nucleotides! Presentation covers alpha, beta, and gamma radiation. Includes a comparison of fission versus fusion. Presentation is the second in a five-part series.

What is half-life and how can decay be used to date items? Viewers find out in this video that details half-life and radioactive decay, as well as the difference between alpha and beta decay.

Does a radioactive cat have 18 half-lives? An understanding of half-life is important in both chemistry and biology, so start your young scientists off the right way — with the good foundation provided by a video that begins with a graph...

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....

Radioactivity is often perceived as dangerous and a threat to our well-being, but you may be surprised at the different applications of this natural chemical process. From the smoke detectors in our homes to treatments for cancer, this...

Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....
