1. In p27 What two types of elements combine to make the following types of bonds? Describe what happens to the electrons when making each of the bonds 1.Ionic 2.Covalent 3.Metallic

2. Tues 9/15 1.If you were absent last class you missed an INB check. Leave your notebook with me today to be graded! 2.Test review 3.Next time: INB Quiz #2 4.Next time: Nuclear energy activity! 5.That’s me!

3. States of Matter

4. Thru pg 28 Definite shape and volume Little particle movement Definite volume, shape changes to fit container More particle movement. Shape AND volume change to fit container A lot of particle movement Very hot gas Atoms break apart into nucleus and electrons 99.99% of all matter in universe Tape in the States of Matter Diagram and add the descriptions below each state

5. The visible Universe is 99.999% plasma. The Sun is about 100% plasma, as are all stars. Plasma makes up nearly 100% of the interplanetary, interstellar and intergalactic medium. The Earth's ionosphere is plasma.

6. Thru 2: pg 29 1. Do a sketch of fission and fusion. 2. Write down the definition for each Nuclear fission-the nucleus of an atom splits apart into smaller nuclei, releasing energy. Nuclear fusion-nuclei of smaller atoms join together to form a larger nucleus, releasing energy.

7. Thru p 30 -Cornell Notes Nuclear Reactions Give off energy in the form of light, heat and gamma radiation. Fission happens on Earth in nuclear reactors and in naturally radioactive elements found within the earth’s crust. Fusion occurs in the core of stars and is the reason why stars shine and give off heat.

8. Our sun Each second, the sun transforms 700 million tons (that’s 700,000,000!) of hydrogen gas into 695 million tons of helium gas through the nuclear reaction of fusion. The remaining 5 million tons of matter escapes as pure energy (about 600 times the weight of water flowing over Niagara Falls in one second).

9. Thru p31 Puzzle Reading Break into groups of 4. Each group will read and discuss a section of the article. Each group will report on their section to the rest of the group. As you read/listen to the article fill in the blanks with the terms that correctly complete the CLOZE passage. Nuclear Energy-Fission or Fusion Cloze

10. Homework Pg. 32 Marie Curie Worksheet Homework Complete BOTH SIDES and tape in as a flap.

11. Out p 27 1.In your own words, briefly explain a fusion reaction. 2.Where did all of the elements on our earth originally come from?
