Mr. Murduck’s Homework/Practice 11/17 – 11/21
Monday – Science –Today we will review last week’s discussion on Earth’s
rotation and revolution around the Sun. The Earth’s rotation causes day and
night. The Earth spins counterclockwise which causes the Sun and moon to
rise in the East and set in the West. The Earth’s revolution around the Sun
and 23.5 degree tilt on its axis causes the seasons. Energy from the Sun
called radiation is mostly absorbed by darker colors like black and reflected
by lighter colors like white snow or ice. Some energy can be conducted from
one object to another. Just as Earth is pulled toward the Sun by gravity, the
moon is pulled towards the Earth. The larger the object, the more
gravitational pull it has on an object. The Sun is so large that it can pull
all the planets towards it. Planetary orbit at different speeds and distances
from the Sun and inertia keeps the planets from being pulled into the Sun.
The pull between the Earth and moon causes our tides. The revolution of the
moon around the Earth causes different phases and eclipses. A day and a year
on the moon are almost the same at about 30 Earth days. This causes us to
only see one side of the moon all year-round no matter where you live on
planet Earth. Homework- – Grade printouts will be going home and need to be
signed and returned by Friday. Test grades from last week’s test are
included. Overall, the class did very well with a B average!! Read pages
185 – 190 in your workbook. Complete the handout passed out in class.
Restate the questions for full credit!
Tuesday – Science- Today I will review last night’s homework and yesterday’s
discussion on gravity in the solar system and Earth’s lone satellite, our
moon. Today we will discuss the inner planets Mercury, Venus, Earth, and
Mars. All 4 planets are small, have a solid rocky surface, have few if any
moons, and are close to the Sun. We will discuss some of these planets in
more detail after Thanksgiving. Homework- – Grade printouts are due signed
and returned by Friday. Read pages 193 – 196 in your workbook. Complete the
handout passed out in class. Restate the questions for full credit!
Wednesday – Science - Today we will review our discussion on the inner
planets and then last night’s homework. We will discuss the outer planets
Jupiter, Saturn, Uranus, and Neptune. These outer planets are much larger
than the inner planets, do not have a defined outer surface, have many more
moons than the inner planets, and are much colder due to their distance
father from the sun. We will discuss some of these planets in more detail
after Thanksgiving. We will discuss tomorrow’s lab and assign everyone to a
group. Each group will have a team name and each member will have a job
responsibility. Homework- – Grade printouts are due signed and returned by
Friday. Complete Journal # 17 for Friday. (DOK2) How are the inner planets
alike and different from the outer planets? Restate in complete sentences.
(DOK3) From what you know about the planets, which planet or planets would be
the most likely form humans to possibly live on? Provide evidence to support
Thursday – Science –Today we will complete a lab related to the size and mass
of the planets. As discussed in class, each team of 4 students has a team
name. Each student has to work together with the team to complete the
assigned task. Each member of the team also has a specific role. Homework ––
Grade printouts are due signed and returned by tomorrow. Complete Journal #17
which was assigned yesterday! We will discuss everyones journal entries
tomorrow. Make sure your entry involves some effort and thought!
Friday – Science - Today we will review yesterday’s lab and discuss
everyone’s journals. We will discuss how planets with the largest volume do
not have the greatest mass due to the density of these planets. The outer
planets are gas giants. We will review our discussion on gravity and inertia
of the planets. Size is also a factor in the revolution of planets around
the Sun. Homework – Have a safe and fun weekend!
