Today's Quote:
Recap:
We are using this week to get all caught up before processing grades. Parents and students are asked to be patient as I work through grades. Please remember, it is also "grant season" and I have many deadlines I am trying to meet while balancing my other duties. Biology 1 classes began their exploration of the cell and how it developed and works. Students were given a video viewers guide to complete as we work our way through Our Secret Universe, The Hidden Life of the Cell. As the video is playing, I stop to discuss things that are being seen. For example, students pointed out that they believe all animal cells are round and shaped the same when, in fact, cells come in many different shapes such as the epithelial cells shown in the video and that cells are the basic building blocks of living things. Cells themselves are composed of molecules and atoms which are the building blocks of all living and non-living things. They are roughly shaped like pyramids. Students also learned about the interstitial spaces between cells and other tissues. I pointed out that blood flows through these spaces and every single cell in your body is touched by blood flow. If it wasn't then those cells would die. Blood is how cells get oxygen and other nutrients and also how the expels carbon dioxide and waste materials. I mentioned that when you breathe in AIR, blood becomes oxygenated at the alveoli within the lung tissues. That oxygen is then carried to every cell in the body and passes passively through the cell's semi-permeable membrane (Definition 5) and carbon dioxide in then picked up and transferred back to the lungs for exhalation. During this process sugars stored by the cells are used to create energy in the form of ATP.This process is referred to as cellular respiration.
We mentioned that all animals have roughly the same sized cells on Earth, but some have more cells than other things. These cells started off as a blastocyst and undergo cellular division in which undifferentiated Stem cells become specialized cells such as skeletal, cardiac, or nerve cell. The process of STEM cell differentiation is explained very well by clicking this link. I also explained the cellular membrane has protein receptors poking through it that monitor the interstitial spaces to protect the cell and bring in the nutrients all cells need.
In Earth Space Science, we began our discussion of the formation of the universe and explored the timeline from the very first fraction of a second after the Big Bang to where most of the evidence says we are headed. This occurred approximately 13.7 billion years ago. While scientists originally thought the universe was about 13.7 billion years old there is new evidence pointing to a much older universe and the possibility that there may have been 12 big Bang incidents. We are about to explore how the plents formed, specifically Earth.
In Intensive English students shared their unit end poems most of which were incredibly thoughtful. We then went to the computer lab to measure our Lexile Growth in reading.
Students who correct ALL the mistakes on their returned papers will receive 10 points more. Make your corrections on a separate piece of paper and staple it to the actual paper, turn it in. Example: If you scored a 60 on an assignment and you correct ALL of the mistakes, I will add 10 points to make it a 70.
