Upcoming Events in Science

Hi!  Just a reminder that we have an Electricity and Magnetism vocabulary quiz tomorrow (Wednesday, March 12th) and a test next week.  The children received their study guide for the quiz last Monday, but I am attaching it here for your convenience as well.  The test will be next Tuesday (3/18) so watch for more information coming home about that as well.  We will be completing the study guide in class over the next few days.  Thanks so much!!!


Vocabulary Study Guide—Electricity and Magnetism

1.Circuit—a path along which negative electrical charges move

2.Conductor—any material that allows negative charges to flow freely through it (examples: wire, metal)

3.Electric Current—the flow or movement of charges through a conductor

4.Electric Motor—a device that uses electricity to make objects move; it contains a spinning electromagnet

5.Electromagnet—a magnet that is made by passing a current through a conductor wrapped around an iron core

6.Generator—a device that changes the energy of motion into electricity; often used to make power when normal power sources fail or cannot work

7.Insulator—any material that does not allow negative charges to flow freely through it (examples: ceramic, cotton oven mitt or potholder)

8.Magnet—an item with magnetism; it has both a north and south pole

9.Bar Magnet—a magnet in the shape of a bar or rectangle, which has its north and south poles at opposite ends

10.Horseshoe Magnet—a magnet in the shape of a horseshoe, which has its north and south poles at each opposite tip

11.Open Circuit—an incomplete path that does not allow electrical current to flow

12.Closed Circuit—a complete path that allows electrical current to flow (if it’s closed, it flows)

13.Static Electricity—an electric charge that collects or builds up on the surface of an object

14.Watt—a unit of measurement for electrical power
