DO NOT TOUCH THE LAPTOPS UNTIL

INSTRUCTED TO DO SO!!!__

Inquiry: What are some pros and cons of nuclear energy?

USING THE LAPTOPS1) THERE IS NO FOOD OR DRINKS NEAR THE LAPTOPS2) Laptops are not for personal use!3) You must ONLY work on the laptop assigned to you.4) You are to ONLY go on the sites assigned by the

teacher5) Keep the computer away from the tables edge6) Treat the laptop with care -> they are brand new!

DO NOT write, scratch, or peel the material labels off the laptop!!

Anyone unable to follow the rules will no longer be allowed laptop use for the rest of the semester, marked as cutting, and will be given an automatic detention.

Inquiry: What are some pros and cons of nuclear energy?

INQUIRY: WHAT ARE SOME PROS AND CONS OF NUCLEAR ENERGY?

Task:Today your goal is to complete 2 tasks:

Task 1: Watch the video at the link: http://www.bbc.co.uk/schools/gcsebite/science/add_aqa_pre_2011/radiation/nuclearact.shtml

This video link will discuss nuclear reaction and nuclear energy (fission and fusion). (20 mins)

Please use headphones (if you have) while viewing the video

Complete the questions on your activity sheet.

Task 2: You will read an article that discusses the pros and cons of fission and fusion. Record the pros and cons based on what you read. (15 mins)

CONTENT QUIZ on THURSDAY a) Vocabulary ( example: atoms, molecules, element, comp. molecules, molecular formulas, subscript, coefficient, group, period, atomic number fusion, fission)

b) Parts of the atom and their function. (Labeling)

c) Using the Periodic Table (atomic number, similarities in groups, atomic mass/weight)

d) Describing make-up of molecular formulas and total atomic weights

e) Identifying pictures of atoms f) Where do all the elements come from.

INQUIRY: WHAT IS MATTER MADE OUT OF? (DIFFERENCE BETWEEN ATOMS, MOLECULES, ELEMENTS AND COMPOUNDS)

“connector”

- Connects certain atoms together- Has – 1 charge

- Atoms id number or “fingerprint”- Has +1 charge

- “Glues” the nucleus together- Has no charge

Nucleus

INQUIRY: WHAT ARE THE PARTS OF AN ATOM?

Same charges repel (move away from)Opposite charges attract

H

Each box on the periodic table represents a profile of a different element or type of atom. Letter symbols are used to represent the name of each atom.

- Symbols always begin with a Capital Letter.

(i.e. H = Hydrogen)- If symbol has more than one letter, the

rest of the letters are in lower case. (i.e. He = Helium)

SymbolStands for Hydrogen1.008 Atomic

L.T: I CAN UNDERSTAND HOW THE PERIODIC TABLE IS ARRANGED AND USE IT TO GAIN BASIC INFORMATION ABOUT DIFFERENT ELEMENTS

Journal Entry

Compare the arrangement of the calendar to the Periodic Table.

How are they similar?

L.T: I CAN UNDERSTAND HOW THE PERIODIC TABLE IS ARRANGED AND USE IT TO GAIN BASIC INFORMATION ABOUT DIFFERENT ELEMENTS.

Period: a row in the periodic table.

L.T: I CAN UNDERSTAND HOW THE PERIODIC TABLE IS ARRANGED AND USE IT TO GAIN BASIC INFORMATION ABOUT DIFFERENT ELEMENTS

Group/Family:Group/Family:

A column in the Periodic Table.

Elements are “grouped”together because they react(bond/connect) with other atoms in a similar way.

Describe the make up of each molecular formula1) O2 (oxygen) 2) CO2 (carbon dioxide)

3) C6H12O6 (sugar)

4) HCl (Hydrochloric Acid)

5) H2SO4 (Sulfuric Acid)

6) Which of the above molecules is NOT a compound? Why?

2 oxygen’s. 2 atoms in total

1 carbon and 2 oxygen’s. 3 atoms in total
