In this biology worksheet, students review the procedures used to complete the lab activity and then examine the purpose and add the information while answering the questions.

Students collect evidence to make inferences about a object hidden inside a sealed box. They think critically and logically to raise questions. Students identify questions that can be answered through investigation. They formulate and...

In this quantities in chemistry worksheet, students solve 13 review problems about percent composition, significant digits, the mole, simple and molecular formulas, balancing equations, stoichiometry, limiting reagents and percent yields.

Young scholars evaluate the ways to control exposure to radiation and determine how to deal with the problem of nuclear waste in a rational rather than an emotional way.

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.

Learners examine what radon is and which isotope it belongs. They discuss the characteristics of isotopes in general and the atomic number. They complete a worksheet to complete the lesson.

Pupils identify the different sources of radiation around us. In this physics lesson, students calculate their estimated radiation exposure per year. They research a current issue about radiation.

Watch beta decay occur for a collection of nuclei or for an individual nucleus.

[Free Registration/Login may be required to access all resource tools.] How and why beta decay occurs, its dangers, beta-minus and beta-plus decay and how to write a balanced nuclear equation for beta decay.

An interactive turtorial on beta decay. Very readable and has a little extra for the advanced student.

Entry explores the process of beta decay which occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.

A basic explanation of beta decay.

This site from Jefferson Lab provides a description of beta decay along with two helpful formula examples. Several links are provided throughout this page for additional information on related subjects.

This site, which is provided for by Wikipedia, gives a brief encyclopedia article on what beta decay is.

[Free Registration/Login may be required to access all resource tools.] What radioactive decay is and the three different types. How it changes one element to another and its dangers.

This article from Khan Academy provides information about radioactive decay. This information is intended for the Class 12 Physics Course (India).

Explains the processes of radioactive decay in primary and secondary modes.

[Free Registration/Login may be required to access all resource tools.] Summarizes the key points about how radioactive particles decay. Includes a few questions to check for understanding.

This article with embedded videos provides information about three main types of radioactive decay: alpha, beta, and gamma.

This interactive unit will take students up close and personal with the nuclei of atoms as they discover some of their more intimate process. These will include radioactive decay, nuclear fission, and nuclear fusion.

Given illustrations, diagrams, or descriptions, students will identify alpha, beta, or gamma radiation.

[Free Registration/Login may be required to access all resource tools.] This lesson explains the types of radioactive decay and how to write nuclear equations. Includes simulations for learning about alpha and beta particle decay.

From The Mad Scientist Network web site. Using a question and answer format, this page discusses three types of nuclear reactions - spontaneous decay reactions, nuclear fision reactions, and nuclear fusion reactions. Each reaction type...
