Week 5

 What did you do in lab today? 

Ted came in and answered any questions we had for the test. 

We gave our presentation first.

 

  • Crater: A round hole on the ground made by a rock from space hitting a planet or moon. 

  • Comet: A space rock made of ice and dust that grows a tail when it gets near the Sun. 

  • Meteorites: Space rocks that fall to Earth and land on the ground. 

  • Meteors: A streak of light in the sky caused by a space rock burning up in Earth’s air. 

 

What is the difference between a meteor and meteorite?  

 

 

Ann Hodges only lady to survive a meteorite hitting her 

 

 

Galaxies  

 

Galaxies are made up of planets, stars and lots of gas held up by gravity 

 

240 million years to orbit the milky way once 

 

Large galaxies can cannibalize smaller ones  

 

Galaxies can collide  

Black Holes  

Objects that are not actually holes are huge clusters of matter that are packed into very small spaces. 


Our Solar System: Inner/Outer Planets/Moons 

What was the big question? 

How did the universe come to be?

 2. What did you learn in Thursday’s discussion?

N/A

3. Read the online textbook, chapter 5

1. What did you learn? 

  • Definition: Asteroids are rocky objects that orbit the Sun, mostly found in the asteroid belt between Mars and Jupiter.
  • Key Concepts:
    • They vary in size from tiny rocks to hundreds of kilometers wide.
    • Unlike comets, asteroids don’t have tails because they don’t release gas.
    • Some asteroids have moons or even rings.
  • Definition: A meteor is the streak of light we see when a meteoroid (a small rock from space) enters Earth’s atmosphere and burns up due to friction.
  • Key Concepts:
    • Meteors are often called “shooting stars,” though they are not stars.
    • If a meteoroid survives its journey and lands on Earth, it’s called a meteorite.
    • Meteor showers occur when Earth passes through debris left by a comet.

2. What was most helpful? 

Learning the concepts and having videos and clear definitions .

3. What do you need more information on? 

I feel like I need to watch more videos and work more on understanding the large concepts instead of all the mini details that can make the content more confusing. 

4. What questions, concerns, and/or comments do you have? N/A
