Welcome to science class!
April 27, 2021
August 27, 2020What if…My teacher gets kicked out of Zoom?
Then..1. If you get assigned
as the host end the meeting.
2. Everyone immediately log out of Zoom.

4. If you do not get back into the meeting after continuous tries, class is cancelled.
5. Refer to agenda slides from website.
In case Mrs. Yazzie loses internet connection:● someone becomes
host● host monitors class
until Mrs. Yazzie returns or four minutes have passed
● after 4 minutes host ends class
● everyone tries to re-enter class
● if Mrs. Yazzie doesn’t return after another 4 minutes, class is ended for the day

Promotion● Thurs., May 27th - Last Day of
School
Agenda-Student Check in-Announcements and Calendar-Student Objective & Essential Question- Vocabulary- Slides-Exit Ticket
Student ObjectiveDay 1, Monday: I can describe the relationship of objects in the solar system.Day 2, Tuesday: I can explain the motion of objects in the solar system.
Essential Questions:1 The Structure of the Solar System
How are the inner planets different from the outer planets?
2 The Inner Planets
How are the inner planets similar?
3 The Outer Planets
How are the outer planets similar?
4 Dwarf Planets and Other Objects
What is a dwarf planet?
What are the characteristics of comets and asteroids?
Big Ideas● The distances between these bodies are huge. ● The solar system consists of the sun and a collection of objects, including planets, their moons, and asteroids that are held in orbit around the sun by its gravitational pull on them ● What natural phenomena do the motions of objects in the solar system produce?
SUPER PINK MOON● What the supermoon looked like around the
world - The Guardian

Weekly Vocabulary
asteroid small, rocky object that orbits the Sun in the asteroid belt between Mars and Jupiter
astronomical unit average distance from Earth to the Sun—about 150 million km
comet object made of gas, dust, and ice that moves around the Sun in an oval-shaped orbit
star object in space made of gases in which nuclear fusion reactions occur that emit energy
meteor streak of light in Earth’s atmosphere made by a glowing meteoroid
meteoroid small, rocky particle that moves through spacemeteorite meteoroid that strikes a planet or moon
impact crater round depression formed by the impact of a meteorite on the surface of a planet, moon, or other space object
Asteroids Recall that asteroids are chunks of rock and ice that never clumped together to form a planet. Most asteroids orbit the Sun in the asteroid belt. The asteroid belt is between the orbits of Mars and Jupiter. There are hundreds of thousands of asteroids. Pallas is the largest asteroid. Some astronomers suggest that asteroids are very old objects left over from the formation of the solar system.
Comets Comets are mixtures of particles of rock, ice, and dust. The particles’ gravity holds them loosely together. As shown below, comets orbit the Sun in stretched-out elliptical orbits.
The dust tail forms from those dust particles and is blown back by solar radiation pressure to form a long curving tail that is typically white or yellow in colour. The ion tail forms from the volatile gases in the coma when they are ionized by the sun.
Meteoroids Millions of particles called meteoroids enter Earth’s atmosphere every day. A meteoroid is a small, rocky particle that moves through space. Most meteoroids are only about as big as a grain of sand. As a meteoroid passes through Earth’s atmosphere, it creates friction. The friction makes the meteoroid and the air around it hot enough to glow. A meteor is a streak of light in Earth’s atmosphere made by a glowing meteoroid. Most meteoroids burn up in Earth’s atmosphere. Some are large enough that they reach Earth’s surface before they burn up completely. When this happens, the meteoroid is then called a meteorite. A meteorite is a meteoroid that strikes a planet or a moon.
Solar System
System of eight planets, including Earth, and other objects that revolve around the Sun.
Scale Model of the Solar System:
A model that shows real objects with all the sizes reduced or enlarged by a certain amount (known as scale)

Terrestrial Planets
The name often given to the four inner planets: Mercury, Venus, Earth, and Mars.
Mercury
Smallest planet, closest to the Sun; does not have a true atmosphere; has a surface with many craters and high cliffs.
Venus
Second planet from the Sun; similar to Earth in mass and size.
Earth
Third planet from the Sun; has an atmosphere that protects life and surface temperatures that allow water to exist as a solid, liquid, and gas.
Mars
Fourth planet from the Sun; has polar ice caps, a thin atmosphere, and a reddish appearance caused by iron oxide in weathered rocks and soil.
