A series of math and science activities feature M&M's® as manipulatives to help kids work through equations. The resource includes exercises on finding averages, percent of compositions, moles in chemical reactions, genotypes and...

Your young physicists analyze the forms of four equivalent exponential expressions representing an amount of a radioactive material in a substance. They show how each expression is equivalent to the others and what aspects of the decay...

This lab is designed to allow students to look at the amount of radiation that is detected at different times from a radioactive source with a very short half-life. This video will help with the lab:...

Determine the half-life of an isotope based on the graph of the amount of the isotope left as a function of time.

Determine the half-life of an isotope based on the activity data of the isotope as a function of time.

Determine the decay constant and half-life of an isotope based on the activity data of the isotope as a function of time.

Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that...

This lesson plan consists of half-life problems for the students to work out.

Kids learn about the science of radioactivity and radiation in chemistry including radioactive decay, types, measurements, half-life, and the dangers.

Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half-life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that...

This Algebra Cruncher generates an endless number of practice problems for radioactive decay -- with hints and solutions! Find the half-life.

Use interactive graphs and other diagrams to answer questions about carbon dating.

[Free Registration/Login Required] Study the basics of radioactive decay and the properties of atomic nuclei in Marie Curie's laboratory and classroom. A PDF worksheet and a video tutorial are also available. [3:32]

This set of activities from the Milton J. Rubenstein Museum of Science & Technology has students investigating how relative dating and absolute dating methods are used to determine the age of rocks and fossils.

In this activity, students use popcorn to simulate the process scientists use to date layers in an ice core.

[Free Registration/Login Required] Learn about how radiocarbon dating works and how anthropologists can use this method to figure out who long ago people lived. A PDF worksheet and a video tutorial are also available. [5:41]

In this amazing interactive tutorial you will learn about what methods are used by geologists to learn about the history of the Earth. Investigate a geologic time scale and learn about how scientists have developed and organized a record...

The team at Periodicvideos has created a TED-Ed Lesson for every element of the periodic table. Because of its radioactivity and short half-life, astatine is an element few chemists come into contact with. [0:34]
