Suzanne Milford

Hello! This is my third year as a Chemistry teacher at T.S.D. I was born and raised in Arizona. I have been an employer at Arizona State Schools for the Deaf and the Blind for total of 19 years. I’ve worked in different professions and then became a High School Science teacher for the remaining 13 years. I’ve taught multiple disciplines such as Chemistry, Physical Science, Biology, Earth Science and Math. I am a graduate from Gallaudet University with a major in Biology and received a Masters of Science in Education for the Deaf from Idaho State University. 

 During my free time outside of school, I enjoy hiking, camping, traveling, and especially doing arts and crafts. I do mainly oil painting and I refinish old furnitures.  I also enjoy spending time with my family, my husband, and my two young children. 

 I hope to continue to bring my knowledge and experience in science and teaching to this fantastic school. I hope the students will become more scientifically literate by performing more inquiry-based activities. I’m truly looking forward to familiarizing myself with the parents and students for the school year of 2016-2017!

Elephant Toothpaste

How does it work? The foam created because each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst (a helper) to remove the oxygen from the hydrogen peroxide. Since it did this very fast, it created lots and lots of bubbles. The foam produced is just water, soap, and oxygen. Hydrogen Peroxide + (Yeast as catalyst) --> Water + Oxygen

The Iodine Clock Reaction!

The iodine clock reaction is a classical chemical clock demonstration experiment to show chemical kinetics in action. It was discovered by Hans Heinrich Landolt in 1886. Two color solutions are mixed and at first there is no visible reaction. Then you'll see the solutions changing to clear or cloudy white color. The iodine is mixed with starch to make a dark blue-black color solution. Then the solution of vitamin C is added to make it clear. How does it work? Iodine has two different “oxidation states” – one where the iodine molecules have a negative charge (I-) and the other where they have no electric charge (I0) Only the iodine with no electric charge can combine with starch to make the blue-black color. Certain chemical reactions (called oxidation and reduction reactions) can make iodine shift back and forth between these two states when it is mixed with Vitamin C solution.

Dancing Raisins

You'll see raisins bobbing up and down in the soda. Why does this happen? Raisins are denser than the liquid in the soda, so at first, they sink to the bottom of the glass. The carbonated soda releases carbon dioxide bubbles. When these bubbles stick to the rough surface of a raisin, the raisin is lifted because of the increase in buoyancy. When the raisin reaches the surface, the bubbles pop, and the carbon dioxide gas escapes into the air. This causes the raisin to lose buoyancy and sink. Then the process happens over and over again until the soda loose its carbon dioxide gases.
