Create a PowerPoint presentation about a specific topic we learned from the subj

Create a PowerPoint presentation about a specific topic we learned from the subject matter of this course (i.e. atomic physics, chemistry, earth science, and/or astronomy) that targets an audience of 5th-graders (10-11 year-olds.)  The presentation needs to be 8 – 15 slides long and have a total word count of at least 500 words.  It should start with a title slide and then a quick summary of what they will learn and what they need to know before the presentation.  Each slide should have at least one picture that has its source cited as a caption. A web address will suffice. Include a bibliography slide.
