Curated OER
World Wide Winds
Students recognize that global winds move in specific directions in specific latitudes and describe that in a written form. They relate the motion of the wind belts to historical navigation.
Curated OER
Galileo's Battle for the Heavens
Students examine the nature of sunspot cycles and define solar minimums and maximums. For this sunspot lesson students construct and evaluate graphs of the current sunspot cycle.

Nuclear Chemistry: How Does It Affect Me?
Eleventh graders study the different areas of nuclear chemistry. In this energy and critical thinking lesson students study radiation, nuclear energy and weapons then divide into groups and create a poster.

Finding the Ages of Rocks and Fossils
Students practice dating fossils. They learn the concept of "deep time"--that earth was formed billions of years ago. They experience excellent hand-outs and virtual age tutorial links.

Chemical Calculations and Chemical Formulas
In this stoichiometry worksheet, students calculate molar masses, empirical and molecular formulas to solve 105 problems and short answer questions.

Excavating the Past
Young scholars discover how palaeontologists conduct a dig for fossils and how they interpret the age of the fossils. In small groups, they prepare a "dig site" consisting of bones, rocks and soil layered in a cardboard box. They switch...

Polishing the Petoskey
Students select a stone and polish it. Throughout the process they demonstrate an understanding of rocks and fossil formation.
Curated OER
Reactor Incident
Students are introduced to Chernobyl incident and the resulting environmental health impacts they watch a PowerPoint presentation, read articles and discuss what they have gained from these sources.
Curated OER
How does Nuclear Fission differ from Nuclear Fusion?
Students examine concepts of nuclear chemistry. They compare and contrast the topics of nuclear fission and nuclear fision. They predict the outcome of reactions based on the types of emissions and reactants.
