A one-page recap of where we’ve been and our science studies through week seven. All the capitalized terms are vocabulary that might be new to you but are very important for understanding biology. – Scott Forbes – 10.06.2020 -
The basic unit of life is the CELL, meaning that if a CELL isn’t present, life isn’t present. So far as we know, CELLS are needed for life.
Viruses are an interesting way to study life because a virus, by itself, is not considered to be living. We’ll return to viruses after we talk a bit about cells.
We talked, a bit, about the basic building blocks of matter – which are ATOMS. There are about 100 different kinds of atoms in nature. You probably already know the names of many of them. Iron, Oxygen, Carbon, Gold, Copper, and others.
In chemistry we dive a little deeper into the structure of an atom. For now, we should know that an atom has a NUCLEUS (a center that has a positive charge.) The positive charge in the NUCLEUS comes from the PROTONS that are found in the NUCLEUS. There is another type of particle in the NUCLEUS that has no charge. It’s called a NEUTRON. Surrounding the center of an ATOM are these very fast moving, negatively charged particles called ELECTRONS.
Our universe is about 14 billion years old and the first kinds of atoms in it were just Hydrogen and Helium. These two elements were around after the BIG BANG, the beginning of our universe.
We know that there, probably, was a BIG BANG – a moment where all space and matter were created, because we’ve graphed the distances and velocity of distant galaxies and we can tell that everything in the universe used to be together in one place.
The first life arose here on Earth about 4 billion years ago because Earth had the right mix of ELEMENTS for life. Especially Carbon, Hydrogen, Oxygen, and Nitrogen. The first life was probably a “simple” CELL, that looked like a BACTERIA. Bacteria are cells with no NUCLEUS.
The first cells gave DNA (a very long MOLECULE) a “safe” place to make copies of itself. We’re not sure if EUBACTERIA or ARCHAEBACTERIA came first. We used to consider all bacteria as one, big, kingdom of living things. It turns out ARCHAEBACTERIA live in very “extreme” environments. There is even speculation that they might exist in the acidic clouds of the planet VENUS.
As life became more complex, cells developed a NUCLEUS. (Not to be confused with the NUCLEUS of an ATOM, they, simply, share the same name.) CELLS combine to form TISSUE, and TISSUE can combine to form organs.
We are the result of four billion years of evolution. We are complex organisms that have CELLS that have a NUCLEUS and all of our ORGANS (like heart, lungs, liver, etc.) are made of tissues, which are made of cells, which are – in turn – made of molecules. Finally, ATOMS combine to form MOLECULES.
VIRUSES are very small “packets” of DNA that can invade cells and force the cell to make copies of the VIRUS. (Some VIRUSES are packets of RNA, which is very similar to DNA.)

Week #5 Test- Due Wednesday 09.23.2020 15:00
This is a short answer test. Please refer to our assigned readings from chapters one and two in our text, as well as our notes. Please notice that the tests and assignments all build on each other, which is why it's important to keep a complete and organized interactive student notebook. Simply write your answers (no need to write the questions) and email them to me before the due date (Wednesday at 3:00 pm.) - Thanks!
1. what is the difference between atoms and molecules?
2. Please write ONE complete Current Events note from any time during our last two weeks. EXAMPLE: The fires in California this season have consumed more timber than in any other fire season in California history.
3. Why is the Metric System (SI) easier to use for science than the Imperial System (feet. miles, pounds, etc) that's still used in the United states?
4. What atoms combine, and in what quantities, to make; (The first is given as an example.).
A. Water: A combination of two hydrogen atoms and one oxygen atom.
B. Carbon Dioxide:
D. Oxygen gas that's released in PHOTOSYNTHESIS:
5. In our science notebooks we did a leaf rubbing. Name THREE of the things that you thought the leaf rubbing resembled.
A. Example answer given in class: It looked like a satellite picture of a river system.
6. (From our reading.). Name FIVE (5) characteristics of living things.
7. (From our reading and our lab.). You've completed and experiment and you now graph the results on an X and Y axis. When you plot the data, you notice that the points on your graph do NOT make a straight line but, instead, are scattered randomly. What conclusions could you make about the relationship between your independent variable and the dependent variable?

August 21st - Friday - Science - Forbes B1 -
I. Good morning: One, final, introduction video posted last night before we jump into the 2020-21 school year. Here's the YouTube link for the video clip.
B. Comparing a science experiment to a golf swing in this one … The scientific process is all about designing a good experiment, controlling variables, and checking out your results so you can refine your theory.
II. Classes on Monday: The ZOOM meeting codes will be posted in our Google Classroom based on your class period. I'll keep the Zoom codes in Google classroom so it's only for those students enrolled in IBL - the Zoom link won't be on the blog. (www.pacificascience.org)
III. Materials: For Monday, August 24th please have a notebook ready to go and a pen or pencil with which to write.
IV. Please join the Zoom meeting with your name as it appears on IBL forms.
A. Example: I'd use: "Scott Forbes". (Full first and last name.) Not "Surfer dude". "-). …. We'll be taking roll and getting to know our classmates.
V. Have a wonderful Friday everyone!
VI. Quick shoutout: Our friend and colleague - Ms. Eifert, is out there helping rescue horses and other animals from the wildfires. 'Happened to talk with some rescuers, last night, in Montara. THANK YOU, Kristi,!!!

August 20th - Thursday - 2020 - Science - Mr. Forbes -
I. Current events: Air quality is expected to be poor today due to the wildfires nearby. Take care not to exercise outside.
II. Class code to join our Google Classroom: cbvqnsv
III. Science notebook: We learn and remember more deeply when we hand write notes rather than type them. Printing out the notes and placing them in an interactive student notebook doesn't count as taking notes. Your notebook is yours to keep and use as a reference.
A. Occasionally, a "pop" quiz (in our new "distance learning" environment) might mean sending in a picture from a specific page of your notebook; so be sure to keep up with our science investigations.
III. Try and keep track of the lengths of a specific shadow at a specific time of day, if possible, this week.

(Remember; you don't have to write down today's notes. We're just getting things up-to-speed for this school year.)
I. Current Events: California fires.
A. The city of Pacifica woke to ash covering cars and homes as wildfires, started by last week's lightning, merged and grew.
B. The California fire season - usually August through November - has been getting longer because of climate change.
ASIDE: Look up the Oakland Hills fire or 1991. A warm, off-shore breeze and dry conditions caused a huge fire storm in the Bay Area.
II. Observation skills and science: Two scientists that we'll learn about this school year are Darwin and Fleming … Both used OBSERVATION SKILLS to change the history of science.
A. Darwin: For his observations aboard the HMS Beagle.
B. Fleming: For his observations that led to the wide-spread use of penicillin.
ASIDE: When you see words or phrases CAPITALIZED please look them up. Be sure to define these KEY TERMS.
III. Observation practice: Locate a convenient object outside. (Tree, house, pole, you, etc.).
A. Note the time and date and mark the length of the shadow.
B. Predict: When you return at the exact same time of day will the shadow be longer, shorter, or will it not have changed?
