Mr. Gonzalez's Science Classes
We have three 6th grade Science classes and two 8th grade Science classes blogging here from the Pacific Northwest in Chimacum, WA! Sixth graders are learning a bit about Mt Saint Helens, environmental science through fresh water ecology, and physical science this year. Eighth graders are learning about life science this year. Please join us as we learn Science by exploring our world.

Mike Smith of Skate for Change came to Chimacum to talk to our students. He spoke to kids in grades 5 though 12 in two separate assemblies. Here's a recording of his talk at the high school assembly:

Here's what the creator of this graph wrote, "I tried to come up with the reason for the daylight saving time change by just looking at the data for sunset and sunrise times. The figure represents sunset and sunrise times thought the year. It shows that the daylight saving time change marked by the lines (DLS) is keeping the sunrise time pretty much constant throughout the whole year, while making the sunset time change a lot. The spread of sunrise times as measured by the standard deviation is 42 minutes, which means that the sunrise time changes within that range the whole year, while the standard deviation for the sunset times is 1:30 hours. Whatever the argument for doing this is, it's pretty clear that reason is to keep the sunrise time constant."

"The acoustic levitator uses two small speakers to generate sound waves at frequencies slightly above the audible range – roughly 22 kilohertz. When the top and bottom speakers are precisely aligned, they create two sets of sound waves that perfectly interfere with each other, setting up a phenomenon known as a standing wave.
At certain points along a standing wave, known as nodes, there is no net transfer of energy at all. Because the acoustic pressure from the sound waves is sufficient to cancel the effect of gravity, light objects are able to levitate when placed at the nodes."
About the Blogger
I started my teaching career in South Central Los Angeles teaching in modified to full bilingual 4th and 5th grade classes. Then I moved to WA State where I have taught mainly 6th through 8th grade. I have enjoyed the culture clash but notice that kids are the same everywhere :o)
My areas of interest are science and technology but I also love studying ancient cultures and learning about different peoples and cultures.
