Day Two of the Egg-Speriment

Much to the delight of (most of) the class, when we observed our eggs this afternoon they had become soft, squishy and rubbery. 

The Eggs Felt Like They Were Made Of Rubber Today!

The egg shells were dissolved by the vinegar. The acetic acid broke apart the calcium carbonate crystals in the egg shell. The bubbles we observed was actually the calcium carbonate being carried away from the egg. 

Eggs and Vinegar Don't Always Smell Very Pleasant
The students decided to extend the experiment even further. We cut one of the rubbery aggs in half, we left two out of the vinegar overnight, and we left two in the vinegar for another night. We wonder what the eggs will be like tomorrow?

Vin-Egg-Ar

Today during Science class we worked in small groups on an experiment involving acids, bases and chemical reactions. Students predicted what will happen when we soak an egg in vinegar overnight. 

We had a class discussion about the chemical makeup of vinegar and also talked about the difference between an acid and a base. The students spent some time observing their eggs and recording their observations. 

We are eager to see what changes occur overnight!

Galileo, Galileo!

Students Were Intrigued By The Thermoscope, Commonly Known As a Galileo Thermometer.

In Science we just finished learning about Galileo Galilei. After completing a webquest, the final project was to write an essay about Galileo impacted our world today. It was challenging for us to image life without the modern day telescope or thermometers.

The Galileo Thermometer Gives Us a General Idea Of the Temperature.

Just In Case Arizona Preparedness Month Poster Contest

Congratulations, Wesley! His award winning design has been made into a poster for promotional use.

Much earlier this school year, we studied about disasters and emergency preparedness. I incorporated the concept into a Social Studies unit, the kids did a webquest and creating a poster displaying what they had learned was the final part of the quest. I mailed the posters to the Arizona Department of Health Services, as they were having an emergency preparedness contest. 
We did remarkably well in the contest and had many winners! I snapped a photo of every entry before I mailed them. Watch the slideshow below to see your child's entry! He or she will have to tell you which poster is theirs because names are on the back. 
Below is the awards ceremony where winners in this contest, the Noetic Math challenge and some of the Mrs. P Be-a-Famous-Writer entries were honored.
