Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

Eighth graders investigate the effect of temperature on the volume of a gas in a closed container. They measure the height of the water in their beaker/container, conduct their experiment, and create a graph to illustrate their data.

Eighth graders discuss atoms and electrons as well as atoic structure. They view atomic structure via the computer. Students watch a demonstration in which the teacher demonstrates glass tubing turning yellow in a Bunsen Burner flame....

Middle schoolers investigate the strength of acids and bases experimentally. They answer the question, "How can pH be used to determine possible product tampering?" by testing acids and bases with litmus paper.

Ninth graders are presented with a problem that has to be solved. The scenario is a mystery that is purely hypothetical. This does draw on the knowledge of previous lessons. The lesson plan contains background knowledge explaining the...

Young scholars examine the differences between a virus and a bacteriophage. They explore various websites, identify the parts of a virus and a bacteriophage, and construct a model of a virus or bacteriophage.

Second graders identify animals with each letter of the alphabet. In groups, they create a PowerPoint presentation which shows the information they have collected about each one. Using all of this information, they create an animal...
