Curated OER
Radioactive Decay
Students explore what radioactive decay is and are able to relate it to the concept of half-life. They are given 100 green beads that represent radioactive atoms and 100 white beads that represent stable, non-radioactive daughter atoms....

Industrialization, Chemicals and Human Health - Math
Students review the units of the metric system, and practice estimating measures before actually converting between the two systems of measurement. They participate in activities to visualize a concentration of one part per million....

Rock of Ages
Students use a video, the Internet and hands-on activities to explore how to determine the age of rocks and fossils based on radioactive decay data.

Isotopes of Pennies
Pupils demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.
