In this radioactive dating worksheet, students use their reference guide in their text book to find the half-lives of 4 isotopes. They use a decay chart to help determine the half-lives and age of given bones and samples of radioactive...

In this half-life worksheet, students use 100 pennies to simulate radioactive isotopes and half-life. They place the pennies in a box and shake the box. All pennies that turn up tails are removed from the box. They represent the isotopes...

In this radon and radioactivity worksheet, learners analyze the data of the isotopes of elements that occur in the decay series of uranium-238. Students answer 6 questions about the isotopes, their half-lives, their potential threat and...

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.

At the end of a general physics course focused on light and electricity, you can administer this exam. Concepts covered include electromagnetism, circuits, induction, light rays, lenses and mirrors, characteristics of light, electron...

Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

How do we know how long ago a dinosaur lived or an ancient fire pit was used? Scholars learn about the application of carbon dating and half lives to discover things about the past. They adjust the amount of radioactive carbon in the...

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...

In this nuclear chemistry worksheet, students answer ten questions about radioactive decay, half life, electron capture and alpha emission.

Students examine the concept of radioactive dating. In this radioactive dating lesson, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.

In this absolute time worksheet, learners answer eleven questions about ways to measure the age of fossils. They define half-life, answer questions about radioactive dating, tree rings and varves.

Students describe how radioactivity relates to alpha and beta particles. Using their properties, they write a descriptive paper about the gamma rays and alpha and beta particles. They calculate q-values and the half-life of a given...

Students study exponential decay and its application to radiocarbon dating. In this exponential decay lesson, students use candy to model the time it takes for something to decay. Students also graph the data they collect and...

Students research separate elements of the theory of Plate Tectonics, then share that information with each other, drawing conclusions from the culminated information.

Students analyze the results of a hypothetical cloning experiment using a restriction endonuclease map obtained from an on-line data source. They answer the question, "How can I tell if the DNA I have obtained from this hypothetical...

In this age of rocks worksheet, students answer five matching questions about terms related to the decay of atoms. They use a strip of paper to simulate half life of atoms and determine the total amount of time it took to deplete the paper.

Students practice dating fossils. They learn the concept of "deep time"--that earth was formed billions of years ago. They experience excellent hand-outs and virtual age tutorial links.

In this absolute time activity, students define radiometric dating, tree rings and varves as means to measure absolute time. They are given information about each of these methods of dating.

In this interactive tutorial you will explore how geologists use clues in rocks to determine the order in which rocks formed. Learn how principles of radioactivity are used to assign actual ages to rocks. Students will explore fossils...
