01.08.2020 - Science and Math recap …
We have less time on Wednesdays so no notes but a good day for science and math crossover and being sure we’re on the same page.  In Science we’re beginning a new book; “Stemscopes” as textbook publishers and school districts keep up with the NGSS. (Next Generation Science Standards.)

  1. Math:  “Math in Science” from our Science books. Eight questions, in class, involving.
    1. … converting percents to decimals.
    2. … converting between meters and centimeters.
    3. … setting up ratios.
    4. … dividing with rational numbers.
II.  Students had today (and tonight) to be sure you’re up through Unit 4, Lesson 4.

III.  Science:  The unit we’re beginning in Stemscopes addressed Ocean Currents so we began with energy and energy transfer. A theme, throughout this year, has been water and its’ unique characteristics that make it critical for life.

A.  Current events:  The earthquake in Puerto Rico and more on the fires in Australia. The earthquakes ties in with plate tectonics and the climate-change induced fires in Australia tie-in with extinctions.
B.  Six facts - chosen but the students - on Astrobiology and how conditions came together on Earth to create conditions for life. Some of the possible facts were;
1.  Plate tectonics recycle materials and provide chemicals for life on Earth.
2.  We’ve been looking for water on Mars because that is where it might be possible to find life.
3.  There are other liquids that might be the basic for life. For example, Titan - a moon of Jupiter - has liquid methane and ethane that flows like the water here on Earth.
4.  Water helps redistribute the heat energy on Earth.  
5.  Earth is just the right distance from the sun for LIQUID water. (The “Goldilocks zone.”)
6.  Water is The Universal Solvent - it helps chemicals mix and react.

01.07.2020 - Tuesday -


  1. Science:  
    1. Current Events:  Two (2) notes on Antarctica.  The deepest place on land was found on the continent of Antarctica.  
    2. Discussion of the difference between Antarctica and the Arctic Ocean.  Time to discuss climate change and the thinning of the Arctic ice sheet.  A good tie in with todays concept of ENERGY and sea level rise.
    3. Notes:  ENERGY as being about movement. Yesterday we review molecules and atoms and today we had notes and a color-in diagram sheet on how molecules move in solids, liquids, and gasses.
    4. Bringing the discussion full circle we related ENERGY to sea level rise and climate change as water molecules take up more space - increase in volume - as ocean temperatures increase and water is added to the oceans from melting glaciers.
II.  Math:
A.  Warm up / Classwork:  Practice with substituting values for variables and introducing algebraic expressions.  
B.  Review of calculating percents.
C.  Notes:  Deeper discussion (begun yesterday) on how to divide mixed numbers and fractions.  
D.  Homework - Unit 4, Lesson 4. - We’ll review tomorrow in class.

01.06.2020 - Monday -  Science class -

  1. Science:  
    1. Current Events:  Two (2) notes on the fires current burins in Australia.  The fires are a result of lower, warmer fire seasons and are tied to climate change.  We’ve seen fires in the Amazon last trimester and both of these events release carbon dioxide into our atmosphere.
    2. Notes:  (Theme - EVIDENCE in science). A brief recap of the discovery, by the father/son team of Luis and Walter Alvarez (UC Berkeley) of the metal element Iridium found at a fossil layer where dinosaurs became extinct.  Iridium is more common in asteroids than here on the surface of our Earth and this helped give evidence to the argument that a large asteroid may have caused the extinction of the dinosaurs.  
    3. Students took some brief notes on the Periodic Table. A very basic introduction just to familiarize students with the shape, size, and purpose of the table.
    4. Assignment:  Research and extinct plant or animal.
      1. WHEN did it thrive?
      2. WHAT, likely, caused it to go extinct.

12.09.2019 - Monday -

New notes and activities for the second trimester.  If you want the archived notes please email me at
12.09.2019 – Monday –
I.  Math: Ratios and Percents – Unit 3 –
         a.  Warm – up / Class work – A brief practice sheet converting ratios to percents.  Reminder: A calculator is required for this class. 
         b.  Notes:  We had some notes on visualizing rate and time using graphs and interpreting graphs of rate and time with a story. Students have to interpret rate graphs in science and math.
         c.  Homework: Be sure unit three, lesson eight is complete for class tomorrow. There are several tie-ins between the current math lessons on ratio and rate and the science unit on Punnett Squares and genetics.

II.         Science:  Unit Two – Punnett Squares and genetics.
a.    Current Events:  CNN – 10 Today. One note on the story on the US entering World War II (We study radioactivity this year and the tie-in with science was the history behind the events that led to the experiments with radioactive isotopes.)
b.    One note on the use of satellites to indicate forest fires.  (Science tie-ins with forest health as well as the program NASA – Eyes on the Earth - )
c.    ACTIVITY:  We did a genetic survey of the class (22 students) and made a Punnett Square on “Taco Tongue.”  The ability to roll the tongue is a dominant trait in humans.
d.    FOCUS:  Genotype vs. Phenotype and dominant and recessive genes.
e.    Homework: Text – Pages 12,13, and 14.
