Kinetic Energy

Big ideas about kinetic energy

• Kinetic Energy = heat, when heat is added kinetic energy increases, when heat is removed kinetic energy decreases
• when kinetic energy increases, the particles increase in speed (move faster), start bumping into each other more often and hit each other harder, and create more space inbetween particles
• when kinetic energy increases, the particles expand
• when kinetic energy decreases, the particles contract

Gas Particles

Some Big Ideas about Gas Particles:

• ·        Gas is a form of matter.
• ·        Gas takes up space.
• ·        Gases are composed of individual particles that are not connected to other particles.
• ·        Gas particles are relatively far apart and in constant motion.
• ·        There is nothing between particles of gas except space.
• ·        They can be forced together through compression. 

Some important Vocab not to forget!!!

1. Compression is to reduce in volume/size due to applied force.
2. Expansion- to increase in volume or size
3. Contraction- to reduce in volume/size due to cooling

Big Ideas about the Periodic Table of Elements

1. Dmitri Mendeleyev created the Periodic Table of Elements
2. He did this by putting the elements on cards and rearranging them til he found an arrangement that worked.  He organized them by putting like elements next to each other in rows (periods) and columns (groups).
3. This created gaps in the Periodic Table which showed elements that were (at the time) yet to be discovered.

Review for Quiz

Here are the 5 words that are the basis for the quiz on Monday.

1. Substance-a form of matter with unique properties
2. Chemical Reaction-occurs when substances interact to form NEW substances
3. Evaporation- Phase change from a liquid to a gas
4. Chemical Formula- shorthand way to show the elements and atoms that make up a substance
5. Elements-the basic building materials of all matter. It cannot be broken down.

Science Times

Some of you may be feeling apprehensive about your upcoming Science Times article.  So, I wanted to give you a few tips to keep in mind as you pen your first piece of journalism.

• 5 Ws- Journalists love the 5 Ws - who, what, when, where, and why - you could also add in how and which.  If your story answers these questions, then you would have a very satisfied reader!  
• The LEAD- The first sentence of your story is called the lead.  Some journalists try to hit all of the 5 Ws in the lead to give people an idea of what their story is about.  It's tricky to get ahold of this idea, but once you get it- it makes life easier!
• Interviews- As you read through news stories, it's not a random listing of facts. A good journalist tells a story.  Interview people from your class and add their quotes into your story to give it a personal touch.

If you keep these three things in mind as you write your story, you'll find that you hit 150 words before you know it!
