After introducing your class to radioactive decay and walking them through the changes in the numbers of atomic particles, give them an opportunity to write equations for the first six daughters in a Uranium-238 decay chain. They also discover how eventually a stable element is formed. This simple activity serves as a support to your introduction to radioactive decay.
Make your lesson 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 decayed atoms. As the activity is repeated with remaining kernels, gathered data will illuminate the nature of half-life and decay rate.
Students describe how the mass of a radioactive isotope changes with time and the factors that affect the rate of radioactive decay. They write nuclear decay equations to represent natural transmutation. This activity is accomplished using pennies to represent isotopes.
In this half-life worksheet, students are guided through the steps of solving radioactive decay problems. They solve nine problems finding rates of decay, half-life and quantities of substances remaining after given amounts of time.
This convenient handout will save you and your chemistry aces time. You will not need to prepare notes, and they will not need to consult their texts for future reference. Detailed notes on radioactive decay are provided and learners are taught how to read related graphs and calculate mass over time. Three examples are supplied to complete together in class.
As physics masters view this presentation, they learn how nuclear power is used in submarines. They use Google Maps to plot a course through the ocean and calculate the time required for surfacing and traveling. They learn about fission, gamma rays, critical mass, and exponential decay. In a second session, they continue to explore radioactive decay and perform calculations using half life. The direct instruction is followed by an activity demonstrating half life using small candies. This is a neat lesson for physics, physical science, or STEM classes.
Mr. Andersen introduces viewers to the use of a Geiger Counter. He explains the fundamental forces behind nuclear radiation and differentiates alpha, beta, and gamma radiation. Finally, he teaches how to write nuclear equations. This video is a well-planned and is an engaging interactive whiteboard presentation. If you are using the flipped classroom model, this is an ideal lesson for high school physics students to view at home.
Examples #3 - 5, a continuation of a previous set of examples, can be used to teach advanced chemistry learners how to calculate values related to radioactive decay. Use the first set in class to teach the concepts, then send this set as a homework assignment.
In this math/science worksheet, students will work in pairs to conduct an experiment based on a decay function which is often used to model radioactive decay. Students will shake M & M's in a cup to rub off the M and then record their data. After repeating this process several times, students will use their graphing calculator to graph the results.
In this nuclear chemistry worksheet, students answer ten questions about radioactive decay, half life, electron capture and alpha emission.
In this math worksheet, students solve differential equations. Students use similar equations, and analyze ways they differ from one another. Students draw directional fields and sketch solutions. The final three questions are applications of differential equations and include problems about mixtures, interest, and radioactive decay.
Students investigate the age of the earth by using accepted scientific methods. They conduct research about the use of radioactive dating and there is a simulation activity of the process. Finally, students measure the radioactive decay of actual rocks to estimate the actual age of the earth.
Students identify the importance of studying exponential decay. In this quadratic functions lesson, students simulate radioactive decay in small groups. Students also present the results found in the investigation and explain why an exponential decay function is an exponential function.
Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.
Students find maps of the region to show rock formations and soil types and use GIS to compare radon levels. They describe three types of radioactive decay, interpret graphs, and follow steps to develop a nuclear bomb or energy.
Through the use of an interactive Web site, students explore C-14 and C-14 dating. Then students analyze an article written about the C-14 dating of the Shroud of Turin and draw conclusions.
In this writing nuclear reactions worksheet, students read about nuclear equations for alpha decay, beta decay and positron emission. They are given the rules for writing nuclear reactions and a sample problem.
Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This resource will help meet that need.
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, a table, and a graphing calculator. Calculator instructions are included, just follow along and let the learning begin.
Sal continues his discussion of decay by showing students the math involved in determining how much a substance is left after one half-life, two half-lives, and even three half-lives have gone by. He sets up a general function of time that can be used to determine the remaining amount of a substance after 10 minutes, or three billion years have elapsed!
