Curated OER
What is Radon?
Learners 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.
Curated OER
Splitting the Atom
High schoolers use the Internet to research the history of the splitting of the atom. They use that research to prepare a presentation on an aspect of that topic. A map is generated to record findings and results.
