Fcat: Get a Half Life!: Teacher Notes

Make your instructional activity 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...

In this radioactive decay and half-life worksheet, students use given half-lifes to calculate the amount of time it will take for certain amounts of elements to decay. They also find the age of samples and determine how many grams of...

Scholars shake their way to understanding half-life with the help of candy. They observe and record which side candy lands on to graph the exponential decay in the fifth lesson of seven integrating chemistry and algebra. Combining...

When you graph an inequality on the coordinate plane you will get two half-planes. The line itself is called the boundary line. One of the halves is called the closed half-plane and the other half is called the open half-plane. How do...

Students 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. Students...

Based off of the hit television show NUMB3RS, this lesson introduces students to the topic of exponential decay and half-life. The lesson is built around Cesium-137, a radioactive isotope, and it's declining radioactivity over the course...

An experiment that will help students in determining the half-life of a radioactive element.

Video tutorial provides examples and tips for finding the half-life of a substance that is decreasing annually by 4%. [6:08]

Define rays and half planes, including the concepts of boundary lines and prerequisite knowledge of coordinate planes. Given linear inequalities in one and two variables, your class will compare the differences. They will also graph...

Twenty-two problems present a variety of practice working with double-angle and half-angle formulas. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the...
