Today we learned about what a compound is and then went into organic and inorganic compounds. Remember that an inorganic compound is one that contains carbon. If the element does not contain carbon it has to be inorganic. Other parts that we covered were enzymes, lipids, and carbohydrates and how these aid and power the cell. This is all very complex so please ask many questions, and don't forget to download the PowerPoint for your notes.
Today we became biome experts on our assigned biomes. We found more than 5 facts on each biome including climate, abiotic, and geographic factors. When completing research we have to remember to use reputable sources, a reputable source has facts and information that are not opinion. Tomorrow we will begin building out PowerPoints and Keynotes to present to the class on Friday.
Common Core Standard/Objective:
7.RI.1 - Cite several pieces of textual evidence to support analysis of what the text says explicitly as well as inferences drawn from the text.
California Content Standard:
7.e. Communicate the steps and results from an investigation in written reports and oral presentations.
The object of today's class was to understand what we saw during the dissection of our cow eye. There will be a test on Friday covering the parts of the eye and their functions. I attached the worksheets below if you lost your notes.
Today we learned began to dissect and learn about the parts of the eye. I am excited about tomorrow's lab and watching all of you follow the step by step dissection PowerPoint located on the Flipped Science homepage. In case you missed any of the expected vocabulary, you can find it below.
Students will actively observe and identify the parts of the cow eye as it is dissected by keeping detailed Cornell Notes.
Welcome back! It was nice to see all of you again after the long Thanksgiving break.
Today in class we learned what the primary light colors are:
Red, Blue, and Green
We then learned a whole new vocabulary:
The big idea is that waves can only travel in one direction, and each color is composed of these waves but with different frequencies. The colors we see is known as the visible light. The visible light is a very slim piece of the electromagnetic spectrum as you can see from the picture above. To add to this, animals have adapted to see in different types of the spectrum (e.g. bees see in ultraviolet while snakes see in infrared). Humans can see in different light spectrums with the help of special glasses or computers.
What is a primary color, and how do we see colors?
To be continued tomorrow . . .
Today we took a quiz on the cell factory to wrap up the week of lessons. The cell is wondrous in how every organelle has a specific job and does that job well. If one organelle fails to perform its assigned job the cell will be unable to function properly. Have a great weekend.
Quiz on constructing the cell factory
Today we broke down what the photosynthesis equation means.
The basic equation is:
6CO2+6H20-->C6H12O6+6O2 or Carbon Dioxide+Water-->Glucose (Sugar) + Oxygen
So what does this mean? Remember that in class we broke down the formula to the exact elements through the use of manipulatives. Organization is important to scientist, and all of you did great in organizing these elements into their correct places. This leads us to your homework question: What does the photosynthesis equation mean? I am looking forward to you explaining it in your own words. Remember that you can watch the main video on the front page to refresh you mind.
Breaking Down the Photosynthesis Equation:
HW: What is the equation for photosynthesis, and what does it mean in your own words?
Today we played "Justify", a terminology game that focused on autotrophic and heterotrophic terminology An autotrophic organism is an organism capable of synthesizing its own food from inorganic substances, using light, or chemical energy. Compare this to heterotrophic organisms, which are organisms that cannot synthesize its own food and is dependent on complex organic substances for nutrition.
In Simple Terms:
Autotrophs create their own food through a process called photosynthesis. Since autotrophs can create their own food, they obtain their energy directly.
Heterotrophs need to eat food; they do not have the chlorophyll. Since heterotrophs do not create their own food then they obtain energy indirectly.
What is Chlorophyll?
Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesize carbohydrates from CO2 and water (H2O). Chlorophyll is green in color due the chlorophyll's inability to absorb light with the green wavelength. Because this wavelength is not absorb, the green light is reflected by the chlorophyll and it is that light your eyes see as green.
Remember this formula since it will be on your test:
Water (H2O) + Light +Carbon Dioxide (CO2) = Oxygen (O2) & Glucose (Sugar)

HW: None, if second draft was turned in
Today we took time to learn how to edit. Being able to explain our work and research through writing is key for scientist to explain their information. Scientists need to share their information and steps with other scientists, and the public, to spread their findings and contribute to knowledge. I look forward to reading all of your second drafts tomorrow.

Today we learned about how natural selection creates genetic diversity in living organisms. The basic break down is this: the better adapted to the habitat that the organism is, the more likely that organism will be able to survive and reproduce. In reproducing the organism is able to pass its genetic material to it's offspring. Every once in a while there are "mutations". Mutations are the process in which such a change occurs in a gene or in a chromosome.
Homework: Complete your rough draft. Due Wednesday 11/06/12
