The deeper the mine shaft, the hotter the inside temperature, but why is that? The video explores different theories about the temperature of the earth through time. The discovery of radiation altered scientists' views, but mysteries...

Can you name the only person to win two Nobel Prizes in two different sciences? After watching a short video on the life, discoveries, and accomplishments of Marie Curie, you can!

When scientists confirm new elements, do these elements always fit in on the periodic table where scientists expect? The second video in a series of 15 discusses how the elements are organized on the periodic table. The resource includes...

Zounds! Who'da thunk it? Colors can be deadly. Viewers learn about the dangers of white (lead), green (radium and cupric hydrogen arsenic), and orange (uranium oxide) pigments used in clothing, ceramics, and home decor.

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.

Scholars control a nuclear reactor and learn to start or prevent a chain reaction with an informational resource that includes connections to nuclear energy as well as nuclear weapons.

Teach the concept of stability in relation to nuclear chemistry with an instructional video that discusses the band of stability as well as radioactivity. Scholars examine the existence of different decay modes and how they develop.

Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...

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...

Marie Curie was a genius and a hard-working, selfless, groundbreaking scientist. A video discusses her work, her personal life, and how impressive both were for the time and place she was born. 

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.

Viewers learn about both natural and synthetic radiation in a video that discusses background radiation from cosmic rays, as well as from radioactive waste, radioactive fallout, and x-rays. It concludes with an explanation of alpha,...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

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....

Provide learners with the tools to further understand nuclear energy and isotopes. Young chemists investigate the components of an atom's nucleus, use symbols to represent various isotope forms, and use the percent abundance of an atom's...

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...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

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.

As physics masters view this presentation, they learn how nuclear power is used in submarines. They use Google Maps to plot a course through the ocean and calculate the time required for surfacing and traveling. They learn about fission,...

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....

Make your lesson 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. As the...

Future physicists will be elated as they engage in a demonstration of radioactive decay that uses balloons and pennies. Balloons represent atomic particles and the students themselves are the atoms. After each flip of the coin, some of...
