This is basically a CD which contains all of my digital products for Middle School Science on one CD. These products were used for 5th - 8th grade and include the following areas of Science: Biomes, Earthquakes, Volcanoes, Astronomy, Human Body, Light, Sound, Weather, along with a few other simple areas. Included in each of these ares are PowerPoints and Printables, along with various Projects and Activities. Many of the PowerPoints and projects are listed individually under my seller account, but this is everything on one CD. The pictures included don't do it justice, I just found it hard to find pictures to upload rather than previews. Two of the pictures are slide examples from PowerPoint presentations, one picture is a grading rubric for a project on the Solar System, and one picture is of an Astronomy Unit.
