Here is a 48 slide PowerPoint presentation created for a 9th grade Earth/Space science class. It has been used for both standard level and honors level students. It is an overview of the entire Earth/Space science curriculum based on the Pearson Earth Science book. It covers Earth's sphere interactions (hydrosphere, biosphere, atmosphere, and lithosphere) and the concept of Earth as a system. It also covers the Global Grid, Earth System Science, the impact of people on the environment, natural resources, and a brief look at the scientific method. There is a Venn diagram at the end which compares and contrasts scientific hypotheses and scientific theories. Look for the accompanying Guided Notes and Earth System Science project!
