There are different types of radioactive decay, and alpha decay is when there are too many protons in a nucleus. Here is a simulation that shows alpha particles being emitted from a polonium nucleus. Learners see how radioactive decay occurs and each nuclei's half-life.

Instructional Ideas

• Simulation is short and fits well and easily into a presentation or discussion about radioactive decay

Classroom Considerations

• When teachers register for free, they gain access to teacher tips, lesson plans, and other related activities
• Simulation best fits upper level middle school and high school learners 

Pros

• You can project the simulation in a number of different languages
• Atoms' nuclei can be changed by moving the half-life arrow or moving the total and potential energy lines

Cons

• None
