Curated OER
Half-life Worksheet
In this half-life activity, students determine how long it takes for a 100g sample of AU-198 to decay to 6.25g. Then they determine the half-life of a radioactive isotope if a 500.0g sample decays to 62.5g in 24.3 hours. Students also...
Curated OER
Working with Half-Life
In this half-life worksheet, students use a given table of half lives, mass, time and amount of original sample to solve for unknowns in nine given half-life problems.

The National Chemistry Olympiad exams are comprehensive tests covering an entire year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your general...
Curated OER
What is the Nucleus Like?
For this nucleus of an atom worksheet, students answer 19 multiple choice questions about the structure of the atom, radioactive decay, isotopes and half life.
Curated OER
Radioactivity-What is the Nucleus Like?
In this radioactivity worksheet, high schoolers answer 40 questions about half life, isotopes, radioactive decay, the uses of radioactivity, nuclear equations and the scientists associated with radioactivity.
Curated OER
Radioactivity
In this radioactivity worksheet, students write the mass number and atomic number for the missing element in the reactions. Students identify the isotope that is more stable and determine the half-life of the isotope. This worksheet has...
Curated OER
Date a Rock!
Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.
Curated OER
Coordination Compounds
In this coordination compounds worksheet, students determine the name, coordination sphere, center of coordination, ligands, and coordination number for given compounds. This worksheet has 5 fill in the blank questions.
Curated OER
What is Radioactivity?
Students use a geiger counter to record changes in the amount of radioactivity produced by different objects. They research articles which mention radiation and discuss them. They work together to complete an activity and worksheet.
Curated OER
How Does Radiation Affect You?
Students identify the use and misuse of radiation. They examine human activities that add to the exposure of radiation. They also discover how it can be useful in saving lives.
