Happy Birthday SuAh

St. Patricks Day

Ms. Hardt helped us celebrate St. Patricks Day with some fun activities. It was a real treat!! Thanks for all your wonderful support Ms. Hardt!!

Making an electric motor in science

Electric motors are everywhere! In your house, almost every mechanical movement that you see around you is caused by an AC (alternating current) or DC (direct current) electric motor.
This simple motor operates by turning a magnetic field on and off at the proper time.

When current flows through the motor’s rotor coil, it generates a magnetic field. (Picture an invisible magnet extending through the center of the ring-like rotor coil.) When you put a permanent magnet near the rotor, the rotor will try to align itself so that the north pole of the “invisible magnet” will face the south pole of the permanent magnet (or vice versa). If the current is turned off before alignment occurs (but while the rotor is still turning), the invisible magnet will cease to exist and momentum will cause the center of the rotor to swing past the permanent magnet. Eventually friction will bring the rotor to a standstill.
If the electrical current is restarted at just the right time, the invisible magnet will re-form and the rotor will continue to spin.

Simple Circuits

Simple Electric Circuits
		Science Process Skills observing communicating comparing
		Materials (per group) D-cell battery paper clips and wire flashlight bulb (about a 3 volt rating)
	Doing the Activity Look at your battery. What differences are there between the two ends? Which end is positive (+) and which end is negative (-)? Take your battery, light bulb, and pape rclip and try to connect them so that the bulb will light. Try as many different ways of connecting them as you can. Draw your arrangements and mark the ones that worked.
	Reflecting Which circuits that you drew caused the light bulb to light? Why do you think the other circuits did not cause the bulb to light up? Is there current flowing through the battery?

Field trip to PIC

Students will be going to PIC to swim on Wednesday, March 4th from 8:30 to 11:15.
They need to come to school with a swimsuit under their clothes with a towel, sunscreen, and swim goggles. They will change back into their clothes before we return to WPS for lunch at 11:15 AM.

Isabelle and Karen will be joining us for the trip. Thanks!!

See you tomorrow!

Managaha Pictures from Ryoko

Aaron's mom Ryoko put together a beautiful photo collage of the Managaha trip. Click on the picture to see the show. You can save pictures to your computer. Thanks Ryoko!!!
