Science 6 Update



This week in Science 6, students have been applying their knowledge of geologic time to create Earth History Brochures, an art project that challenges student scientists to make an informational and artistic brochure highlighting the major events, life forms, and time periods of Earth’s history. Some noteworthy discoveries include the time period when an important index fossil (trilobites) lived, when Earth’s atmosphere became filled with oxygen from stromatolite bacteria paving the way for the largest biological diversification in history (Cambrian explosion), the fact that dinosaurs were alive relatively recently (up to 65 million years ago), and when the first homo sapien ancestors evolved (about 200,000 years ago.)
