Determining Absolute Age
How can radioactive decay help date old objects? Learners explore half-life and radioactive decay by conducting an experiment using pennies to represent atoms. Young scientists graph data from the experiment to identify radioactive decay...
Curated OER
Nuclear Energy
Atomic theory as a philosophical study was explored even by the Ancient Greeks. The knowledge of atoms was developed in the 17th century. This PowerPoint explains how by the 1940's, splitting of the atom was discovered and since then,...
