Challenge your class to solve a murder using a bloody stain left at the scene of the crime. Using simulated Neo/Blood, they'll identify whether or not the stain is actual blood. Then they'll solve the crime by performing ABO and Rh typing of both the stain as well as samples from the victim and several suspects. Students will learn about blood groups, blood typing and how blood stains can be used in solving crimes. Simulated Neo/Blood looks and behaves like real blood, giving you and your class quick, easy and completely safe results. This revolutionary substance realistically simulates agglutination. It even contains simulated, microscopic blood cells - of the same size and concentration as in actual human blood.

Natural resources are created by Earth's processes and used as a source of energy for all life on Earth. While some are created over the course of millions of years, others are continually generated each and every day. In Natural Resources, students will examine both renewable and nonrenewable resources, touching on their sources and many uses. Discover the best methods of conserving nonrenewable resources, including how they are recycled and cleaned. A fun, hands-on investigation illustrates how students can observe the many different kinds of particles that can be found in the air, while a geothermal plant provides the setting for a look at how people can turn volcanic heat into electricity. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
