Calculating Half-Life Problems

Young scientists use a activity to help them perform a lab on the decay of a radioactive element. The activity serves as both a task guide and a lab sheet for pairs of learners. This activity requires a calculator and has excellent...

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....

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...

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,...

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.

I so hope you'll learn about isotopes. Watch a video to understand that isotopes of an element have the same number of protons but different numbers of neutrons. Then solidify the knowledge by examining examples of hydrogen,...

Ready to tame LEO the lion before he says GER? Get chemistry scholars acquainted with the half reaction method for handling redox equations using a video from the JFR Science playlist. Step-by-step instructions and great tips provide...

Participate in a little chemistry Q and A! Part of a larger series on reactions, an informative lesson takes questions from viewers and crafts responses. The video explains how we arrive at an accurate half-life of a radioactive...

In this half-life worksheet, students calculate the half-life of isotopes, they find masses of isotopes remaining after specified times, and they find particular amounts of time needed to pass for given masses of isotopes to decay.

A video lecture discussing radioactive decay and half lives. Understand how half life and the mass of the compound remaining is calculated by following the examples given in the lecture. [12:31]
