NASA KIDS - A fun site for kids and teachers. There is a news for kids section, a teacher's corner, projects and games, and a space and beyond section. Matter - Everything you need to know about matter. Originally done for fourth graders, it is basic enough for our first graders. This would be a good site to use with an LCD projector or TV hook-up to do a presentation for students.
Some interaction is involved.
Explore the different areas of the center and find out what exhibits are being shown. This is an excellent field trip for this unit and for other first grade science units. This site includes photos and descriptions of many different kinds of rocks that can be printed in the Discover Earth's Treasures section. Here students can take a virtual tour of various exhibits. Geology Link - Contains areas such as a virtual field trip to two sites in Maryland, minerals, an image gallery and a whole lot more.
