EY Engineers Construct Writing Machines

Our 4/5 students were presented with a new engineering task today. They are engineers for the company, Write On, Inc. Their task is to build the company’s new prototype writing machine, the Writing Wizard 1000. Today students began construction and testing. On Monday they will finish their devices and then have our quality control (QC) personel (other student teams) assess their work using a company scoring guide. To finish out next week, students will design, build, test, and assess a successor to the Writing Wizard 1000. Check out a few clips of today’s activity.

Chinook Alevin Update

Here is the latest video update of how our chinook salmon alevins are developing.

Active Alevins

Our chinook salmon alevins are starting to become quite busy in their little worlds. Activity is increasing everyday in both incubators. Ammonia levels have been a concern so we have changed out the water several times. Thanks to Mr. Segundo who has hauled in numerous five gallon buckets of water from our well pumphouse on several chilly mornings. You will note a clearing in the rocks. This is where we dumped in the new water from the buckets. It is interesting to see how the salmon alevins react to it. Stay tuned for more developments!

Kiwanis Terrific Kid Award 2013

joy_kiwanisEach year the Newberg Kiwanis Club recognizes Newberg students from each elementary school for their excellence in the classroom. At their November meeting, Ewing Young fifth grade student, Joy A., was recognized for her outstanding work ethic and exceptional writing skills.  Presenting the award was former EY principal, Mr.  Purcell. Also on hand with Joy were EY principal, Mr.  Milner, EY Teacher, Mrs. Reed, and Joy’s mother.


Bring on the alevin stage!

This morning we were greeted by about 1,000 wiggling chinook salmon alevins in both classroom incubators combined. Over the weekend all of our eggs hatched. When the eggs hatch, it is common to find a white frothy foam on the surface of the water and to have the water a bit cloudy. This is caused by the egg yolk residue mixing with the water. As a result, the ammonia level in the incubators usually climbs to dangerous toxic levels. To remedy this, we change out half or more of the water to dilute the ammonia. The incubators also are equipped with ammonia filters, but it often isn’t enough to keep the level down once they hatch. You will notice the alevins have very large yolk sacs. These are the food sources for the young salmon until the sacs become used up and the fish become free-swimming fry. Stay tuned for more updates!

Our Salmon are Hatching!

Our chinook salmon eggs are beginning to hatch.  Unlike our previous trout egg hatches in which most eggs hatch in a single day, the chinook eggs are gradually hatching. Over the past two weeks our students have conducted daily water tests and observations, used math to calculate hatch date predictions and survival rates, learned about food chains and webs, and they are currently creating scale drawings of salmon. In the coming weeks we will study energy and learn how salmon and energy needs must coexist.

Color Tiles site

This site with manipulative tiles may be helpful this evening for our 4th grade math assignment today. We’re working on rectangular arrays, dimensions, factors and arrays today in preparation for larger multiplication and area models.
