II. Study Guide
– Things we’ve covered that will be on Thursday’s test.
A. Key vocabulary terms
3. Cell Membrane
B. Elements found in living things.
Remember our C-H-O-N color-in handout.
C. Why is WATER essential (important) for
D. Characteristics of living things. “How
do we know if something is alive?”
E. One fact from Current Events. (Our Current Events always related to
something we study this year.)
- Students had time to be sure they’ve
completed the text pages 5, 10, 15, 16 and 23 through 26. We also had a moon observation as our
moon is a waning gibbous currently – It was setting around 9:00 am today.
B. Math test on Friday focusing on
parallelograms and triangles as well as decomposing figures to determine area
A. Lab on using the Triple Beam Balance –
B. Lab on determining the DENSITY OF
WATER (One gram per cubic
C. Density and specific gravity are eighth
grade standards but we need a basic understanding for cells and earth science
in sixth grade as we study;
Life on Earth!
D. A very brief (12 minute) video clip on
the history of our universe. From the Big Bang, 14.5 billion years ago to the
formation of Earth 4.5 billion years ago, to the first life on our planet.
(About 3.5 to 3.7 billion years ago.)
HOMEWORK: OBSERVE THE MOON! (ongoing for three weeks.)
Hi STEAM students. As
we complete the two weeks on Civil Engineering - focusing on buildings and houses - we will spend some time
on aeronautical engineering. Having grown up right here next to San Francisco
International Airport (SFO) it seems a natural engineering subject to explore.
Today we watched a
bit of “October Sky.”: Based on the novel “Rocket Boys” by Homer Hickam. I’ve had the good fortune to visit the
area of West Virginia where the novel was based. My father grew up in Charmco,
West Virginia and we passed around a sample of coal from the very mine in the
movie. We’re only watching a selected piece of the movie but I highly
recommend. the novel. The book recounts the efforts of a small group of
Coalwood, West Virginia high school students as they attempt to build and fly
model rockets to enter a science fair.
Homer Hickam was kind
enough to respond to a letter and the story is a wonderful example of the
scientific method in action.
a.Unlike addition or subtraction, there’s no
need to find a common denominator when multiplying fractions.
b.When dividing fractions we take the
reciprocal of the second fraction (the DIVISOR) and, then, multiply as usual.
c.While teaching eight-grade math last year a
number of students tried to rely on calculators to convert fractions into
decimals before performing arithmetic on the fractions. We will NOT be using
calculators to work with fractions. We’ll be practicing working with rational
II.Class work and homework
a.Goal for the homework is pages 49 through
55. Be sure to arrive at class with any questions you may have on the homework.
A. We passed back our most recent quiz and
reviewed the test correction procedure. Tests are due back by Thursday with
The question on the recent quiz about how many “small” triangles make one
square unit was a bit unclear and answers of 1/16 and 1/32 were both accepted
as correct. The grades will be updated Thursday.
Some examples of decomposing figures to determine area and perimeter.
This week’s optional, extra-credit, was made available. It is due Friday.
Homework: Complete he unit on parallelograms.
A. Current events
1. One note on hurricanes, typhoons, and
2. One on the Indian mission to our moon.
1. Five facts and an overview of the
vocabulary terms from “Bill Nye – Cells.”
A. Scale model houses should be secured to
their “land” and a compass rose should be added.
1. A brief lesson on considerations in
building a house, including the height of the sun in the sky at various times
of year and the direction the house faces.
2.Five STEAM questions on building your
Students worked on Unit One, Lesson three in class and are assigned through the end of lesson four for this evening. We had some notes on parallelograms and will correct he homework and our last quiz in class tomorrow.
A quadrilateral flow chart was introduced, like the one below.
We had Back to School night on Wednesday and our first math quiz on Friday. The math quiz was based on the composing and decomposing of figures that we did both in class and for homework. Students could use their text for the test and the Area and perimeter questions were straight from the homework assigned on Tuesday.
I. Warm up: A quick, word-problem, challenge to introduce/review the
concept of CONVERSION FACTORS. These are important in both math and science.
A. Word problem of how long it would take
Los Angeles to be next to San Francisco of the San Andreas Fault is moving the
cities about two inches closer – on average – each year?
B.We’ll jump back into “Open Up – 2.2 –
Comparing Shapes – “ tomorrow. Students had a bit more practice on area,
perimeter, and working backwards (key problem-solving skill) to calculate the
length of a side of a square given the area.
C.Perimeter and area practice work sheet was
assigned. Some students completed it in class. If not completed in class it
“rolls over” into homework.
II.REMINDER: A basic calculator is
required for this math class.
