DO NOT TOUCH THE LAPTOPS UNTIL INSTRUCTED TO DO SO!!! __ DO NOT TOUCH THE LAPTOPS UNTIL INSTRUCTED TO DO SO!!! __ Inquiry: What are some pros and cons of nuclear energy?

USING THE LAPTOPS 1) THERE IS NO FOOD OR DRINKS NEAR THE LAPTOPS 2) 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 teacher 5) Keep the computer away from the tables edge 6) 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?

Task: Today your goal is to complete 2 tasks: Task 1: Watch the video at the link: /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.

Electron (e-)Protons (p+)Neutrons (n) Electron (e)- Neutron (n) Proton(p+) “connector” - Connects certain atoms together - Has – 1 charge - Atoms id number or “fingerprint” - Has +1 charge - “Glues” the nucleus together - Has no charge Nucleus

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) Symbol Stands for Hydrogen 1.008Atomic Mass/Weight (Weight of the Atom) 1 Atomic # (# of protons)

Journal Entry Compare the arrangement of the calendar to the Periodic Table. How are they similar?

Period: a row in the periodic table.

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 formula 1) O 2 (oxygen) 2) CO 2 (carbon dioxide) 1) C 6 H 12 O 6 (sugar) 1) HC l (Hydrochloric Acid) 1) H 2 SO 4 (Sulfuric Acid) 2) 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 6 carbon’s, 12 hydrogen’s and 6 oxygen’s. 24 atoms in total 1 hydrogen and 1 chlorine. 2 atoms in total 2 hydrogen’s, 1 sulfur, and 4 oxygen’s. 7 atoms in total O 2 is not a compound because it only has 1 element.

What is the total weight of this H 2 O molecule? H O H amu amu Ans: amu’s amu’s amu = amu’s

What is the total weight of this 2 H 2 O molecule? O H amu amu Ans: amu amu OR amu X 2= 36.03amu H amu O H amu H amu amu +

Chemical Bond (Chemical reaction) vs. Fusion (Nuclear Reaction) (Stars) Inquiry: Where do most of the different types of elements come from?

Chemical Bond: Fusion: 2 atoms connecting the nuclei of 2 atoms by the e- to form a molecule joining to form a new element HYDROGEN Chemical reaction: When new molecules are formed. Vs. Nuclear reaction: when a different element is formed. Inquiry: Is fusion technology good or bad?

Identify the name of the element Carbon (C). 6 protons (Atomic # 6)

Identify the name of the element Nitrogen (N). 7 protons (Atomic # 7)
