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

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...

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...

Upper elementary or middle schoolers will explore non-linear functions, graphing, and the curve of best fit through real-life data collection and trial analysis. They explore the concept of half-life and radioactive decay using M&Ms,...

Here is a comprehensive and cohesive final exam for your high school physicists. A variety of question styles are incorporated, such as multiple-choice and problem-solving. Topics are too many to list, so you will want to review the exam...

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 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 half-life instructional activity, students are given a particular mass of an isotope of cesium and its half life. They are to determine how much cesium will remain after 90 years. They are guided through the problem solving process.

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.

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.

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

Pupils study chromosomes and how molecular half life affects them.  In this chromosome instructional activity students complete several lab activities on calculating half life, and cracking alkanes. 

In this exponential growth and decay worksheet, students identify equations as growth or decay, find balance in an account, find half-life, identify interest rate, identify the initial amount, and identify the growth factor. 

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.

High schoolers explore decay functions and the half-life of a substance. Through an M&M activity with calculators, students collect and graph data. They determine the linear, quadratic and exponential functions of the graph. High...

Students distinguish between natural and man-made radiation. They measure radiation using a Geiger counter and investigate footprints of radiation.
