Math

“Friday light.”

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.

09.11.2019 – Wednesday – Math

I. Notes on multiplying fractions

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
numbers.

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.

III. Test corrections are due tomorrow.

IV.
Optional
Extra Credit is due Friday.

09.11.2019 – Wednesday –

Science

I. Current Events:

a. A very brief clip from “Brainpop” and “CNN
Student News” (5 minutes) on the events of 9/11 , 2001.

b. Current events often has stories of
international relations. No notes required for this part of the class.

II. Triple Beam Balance

a. Brief notes on the three beams of the
balance and how to use careful lab procedures to carry, handle, and use the
triple beam.

b. Our triple Beam balances measure the MASS
of an object.

c. The IS a difference between mass and
weight.

III. LAB

a. Students were asked to find the mass of
eight objects.

1. Paper clip

2. 1 seed

3. Graduated cylinder

4. Golf ball

5. Toy car

6. Coin

7. Pencil

8. Ten seeds

09.10.2019 – Math / Science / STEAM

I. Math

A. We passed back our most recent quiz and
reviewed the test correction procedure. Tests are due back by Thursday with
corrections.

B.
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.

C.
Some examples of decomposing figures to determine area and perimeter.

D.
This week’s optional, extra-credit, was made available. It is due Friday.

E.
Homework: Complete he unit on parallelograms.

II. Science

1. One note on hurricanes, typhoons, and
cyclones.

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
own house.

Math - 09.09.2019 -

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.

O9.09.2019 Science – Monday –

I. Observation: Properties of water.

A. We had some drops of water on waxed
paper an observed how the water tended to stick together and was repelled by
the paper; much like a car after it’s been waxed.

B. Wax is very similar to fat or LIPIDS.
Cells have a lipid layer that makes them like little “bubbles” of water.

C. The water molecule is POLAR – It has a
positive and a negative side. Water molecules tend to stick together. Almost
like tiny magnets.

II. The second part of the class had
students observe food coloring dropped into water. Students were asked if it
was possible to avoid having the food coloring mix with water.

A. Atoms and molecules are always moving.

B. Water is a SOLVENT.

C. The food coloring will eventually mix
no matter what – so long as the water is above ABSOLUTE ZERO! (But, that’s for
eighth grade chemistry J)

III. Finally, student used our in-class
textbooks to make a list of the similarities and differences between PLANT
cells and ANIMAL cells.

A. Plant cells have vacuoles to store
water.

B. Plant cells have cell walls to
help the plant stay rigid.

C. Animal cells have lysosomes to help
remove waste.

Thursday and Friday update ...

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.

09.03.2019 – Tuesday – Math –

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.

takes up.

c. Students shared 25mL graduated cylinders in
their groups.
