This work should be preceded by two things. First, students should have an opportunity to explore electric forces on a macroscopic scale by using pieces of plastic that obtain an electric charge when rubbed. Second, students should be introduced to the main concepts in the text below in a lecture-style or class discussion format. Most importantly, they should be shown a full table of the isotopes: one is available from Wikipedia.
Here are some links with visuals and charts for various concepts that need to be covered in lecture/discussion:
Nuclear Notation and Forces
Fundamental Forces
Neutron Excess Table of Isotopes Diagram

Also, show this table of radioactive decay modes with animations
And this page about three types of radioactive decay.
And the Interactive Chart of Nuclides, NuDat 2.4, from the National Nuclear Data Center, Brookhaven National Laboratory.
Here is a great glossary of nuclear terminology.
PhET Simulation about Balloons and Static Electricity
“Travoltage” PhET Simulation
PhET Alpha Decay Simulation
PhET Beta Decay Simulation
PhET Radioactive Dating Game
PhET Simulation for Nuclear Fission
See the accompanying assignments:
Activity: Intro to Nuclear Chemistry

Homework: Nuclear Chemistry and Radiation
Lab: The Geiger Counter
