The rally Saturday is the latest effort by people wanting to shed more light on the Aug. 5 shooting of 21-year-old John Crawford III inside the store in Beavercreek.

Predictions from the Ice
By examining past trends in carbon dioxide and methane levels as well as temperatures, scientists can predict future trends through ice core samples.
Students will investigate the properties of carbon dioxide and methane, identify natural and man-made sources for both gases, and graph carbon dioxide and methane data for a 160,000-year period. They then engage in an online simulation and examine a climate timeline to gather additional information before predicting the future of global climate. Finally students predict how current climate indicators will appear in ice cores.
