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

  2. 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.

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

  4. 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.

  5. Inquiry: What is matter made out of? (difference between atoms, molecules, elements and compounds) =

  6. 1) 5) 6) 2) 7) 3) 4) 8) State whether the picture represents an atom, molecule, or molecule/compound Each color represents a different element. H H Compound 3 atoms 2 element 2 atoms; 1 element H O Ca Atom 1 element 2 atoms; 2 elements O H Li H H Molecule 4 atoms 1 element H H Compound 3 atoms, 3 elem. Molecule, 2 atoms; 1 element Li O O H

  7. Inquiry: What are the parts of an atom? Electron (e)- Neutron (n) Nucleus Proton(p+) “connector” - Connects certain atoms together - Atoms id number or “fingerprint” - “Glues” the nucleus together - Has – 1 charge - Has +1 charge - Has no charge

  8. Same charges repel (move away from) Opposite charges attract Inquiry: What are the parts of an atom?

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

  10. 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

  11. 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.

  12. Group/Family: L.T: I can understand how the Periodic Table is arranged and use it to gain basic information about different elements Group/Family: A column in the Periodic Table. Elements are “grouped” together because they react (bond/connect) with other atoms in a similar way.

  13. One house called B2W3 Why are 2 houses called 2 B2W3 Inquiry.: How do I describe the make up of different molecules? (Chemical/Molecular Formulas) ( )

  14. 3 B2W3 Inquiry.: How do I describe the make up of different molecules? (Chemical/Molecular Formulas) Coefficient (co-e-fish-ent) Subscript (sub-script) Vs.

  15. 1) 3 HO2 a) How many molecules in TOTAL? b) What does H rep.? How many in EACH? c) How many H atoms in TOTAL? d) What does O rep.? How many in EACH? e) How many O atoms in TOTAL? f) How many atoms in total? L.T.: I can determine the total weight of various molecules. ( ) 3 Hydrogen 1 3 x 1 = 3 Oxygen 2 3 x 2 = 6 3 + 6 = 9 H H H O O O O O O

  16. 2) 3 Ho2 a) How many molecules in TOTAL? b) What does Ho rep.? How many in EACH? c) How many Ho atoms in TOTAL? d) How many atoms in total? L.T.: I can determine the total weight of various molecules. ( ) 3 Holmium 2 3 x 2 = 6 3 x 2 = 6 Ho Ho Ho Ho Ho Ho

L.T.: I can determine the total weight of various molecules. 4 Carbon 1 4 x 1 =4 Hydrogen 3 4 x 3 =12 H H H H C C C C H H H H H H H H

  19. Describe the make up of each molecular formula O2 (oxygen) CO2 (carbon dioxide) C6H12O6 (sugar) HCl (Hydrochloric Acid) H2SO4 (Sulfuric Acid) Which of the above molecules is NOT a compound? Why? L.O.: SWBAT explain the purpose of the Periodic Table is and to read a chemical formula. 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 O2 is not a compound because it only has 1 element.

  20. What is the total weight of this H2O molecule? L.T.: I can determine the total weight of various molecules. O H 15.999 amu H 1.008 amu 1.008 amu Ans: 1.008 amu’s +1.008 amu’s + 15.999 amu = 18.015 amu’s

  21. What is the total weight of this 2 H2O molecule? L.T.: I can determine the total weight of various molecules. O O 15.999 amu 15.999 amu + H H H H 1.008 amu 1.008 amu 1.008 amu 1.008 amu 18.015 amu 18.015 amu Ans: 18.015 amu + 18.015amu OR 18.015amu X 2= 36.03amu

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

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

  24. Identify the name of the element Inquiry: Where do most of the different types of elements come from? - - - + + + - + - + + - - - Carbon (C). 6 protons (Atomic # 6)
