Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

In this radioactivity quiz worksheet, students complete a 10 question true/false quiz. Quiz is also available as a student handout and Powerpoint presentation. 

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

Students demonstrate rates of decay of unstable nuclei can be measured. They understand ratios and multiplication of fractions. They simulate radioactive decay. They read about the accomplishments of scientists.

Students use a video, the Internet and hands-on activities to explore how to determine the age of rocks and fossils based on radioactive decay data.

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

Learners read periodicals relating to radioacitivity and interpret a Geiger Counter. They work in small groups, share information and help each other explain the Geiger Counter. They discover the relationship distance to...

Young scholars are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

Students conduct a simulation to determine radioactive decay and half-life. Using pennies, dice or sugar cubes as isotopes placed in shoe boxes simulating rocks, they hold five trials representing 1000 years each to find the theoretical...

In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

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...

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...

Learners demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.

Students take on the role of members of a concerned citizens group and discuss the transportation of spent-fuel rods from a local nuclear power plant and the safety issues that surround the power plant. Students work in groups to write...

Learners participate in an Electron Square Dance in which they act the part of atoms. They follow the structure of different atoms suggested by the teacher.

Students examine concepts of nuclear chemistry. They compare and contrast the topics of nuclear fission and nuclear fision. They predict the outcome of reactions based on the types of emissions and reactants.

Young scholars investigate elements by by defining scientific terms.  In this Periodic Table of Elements instructional activity, students utilize a glass of water, and powdered fruit drink to perform a lab activity demonstrating...

Students read an article about radon and its properties. They examine a periodic table and identify the numbers surrounding an element. They discuss the harmful and helpful effects of radiation.

High schoolers use the Internet to research the history of the splitting of the atom. They use that research to prepare a presentation on an aspect of that topic. A map is generated to record findings and results.
