THE MAILBOX Intermediate Feb./Mar.1998
Kit #1 refers to the kit used in the previous lesson. Small groups of three or four may share kits. Not all things will accept or hold a static charge in the same way. The activities in this section will demonstrate how to create a greater charge and why some items are better able to hold a charge. Materials such as wool, silk, flannel, and fur or hair will hold a charge well, as will items made of rubber, glass, and plastic.Conductors of electricity (such as metal) do not hold a charge well.
1-Use science process and thinking skills.
4-Communicate effectively using science language and reasoning.
Invitation to Learn:
Ask the student to make predictions about the answers to questions like the following: Will all materials hold equal static charges? What types of items will hold the greatest charges? Does the type of material used have an effect on the production of a static charge?
Review the previous lesson and activities with the students. Emphasize that like charges repel and opposite charges attract. Recall examples of real life occurrences of static electricity including lightning.
Prepare a list of what will and won't hold a charge or list items previously tested and other similar items in your journal. Students will identify which items will and won't hold a charge.
This lesson is part of the Fifth Grade Science Teacher Resource Book . The TRB3 is designed to be your textbook in teaching science curriculum to your students. This book covers all the objectives of each standard and benchmark. If taught efficiently, a student should do well on the End-of-Level (CRT) tests. The TRB3 is designed for teachers who know very little about science, as well as for teachers who have a broad understanding of science.
