Science 9 – Final Exam Preparation

1. Science 9 – Final Exam Preparation Mr. Francis

2. Exam Format • ~60 marks • A variety of question formats with an emphasis on short answer • You will be making a cheat sheet over the next few classes in preparation for this

3. What is covered… • 3 units – life sciences, chemistry, and electricity • Today – life science/reproduction review • Friday – chemistry review • Monday – Electricity review

4. Life Sciences – Reproduction… the learning outcomes • B1 explain the process of cell division • B2 relate the processes of cell division and emerging reproductive technologies to embryonic development • B3 compare sexual and asexual reproduction in terms of advantages and disadvantages

5. B1 explain the process of cell division • What is the role of cell division, why is it important? • What are the important structures in the cell associated with cell division? • Where is the “information” that makes organisms unique stored? What is that molecule like? • What processes occur in somatic cells vs gametes?

6. B2 relate the processes of cell division and emerging reproductive technologies to embryonic development • We briefly looked at reproductive technologies, you should understand what a GMO is, selective breeding, artificial insemination, in vitro fertilization

7. B3 compare sexual and asexual reproduction in terms of advantages and disadvantages • Be familiar with different types of asexual reproduction including fragmentation, binary fission, vegetative reproduction, spore formation, and budding • What are advantages and disadvantages of asexual reproduction? • Be familiar with different variations of sexual reproduction, and unique adaptations including hermaphrodites, conjugation, external fertilization, internal fertilization as well as differences between marsupials, monotremes, and placental mammals. • What are advantages and disadvantages of sexual reproduction.

8. What should I be using to prepare? • Notes, old assignments • Textbook references – Chapters 2 and 3 • Pages of specific value for studying are 68,69,102,103

9. Chemistry – Learning Outcomes and what you should know • C1 - use modern atomic theory to describe the structure and components of atoms and molecules • Distinguish between atoms and molecules • Identify the three subatomic particles, their properties, and location within the atom

10. C2 – use the periodic table to compare the characteristics and atomic structure of elements • Distinguish between metals, non-metals, and metalloids • explain the organization of the periodic table of the periodic table (atomic number, atomic mass, properties, families) • Draw a Bohr model of each atom up to atomic number 20

11. C3 – write and interpret chemical symbols of elements and formulae of ionic compounds • Differentiate between elements and compounds • Write chemical symbols for atoms and ions of elements • Differentiate between atoms and ions in terms of their structures using Bohr models • Write chemical formulae for ionic compounds (metals and non metals, multivalent metals and non metals, polyatomic ions) • Name ionic compounds, given their chemical formula

12. C4 – Describe changes in the properties of matter • Identify physical properties of matter, including mass, volume, density, state at room temperature, colour, melting/boiling point, and conductivity • Differentiate between physical and chemical change using observable evidence • Name the changes of state of matter and describe how the kinetic molecular theory explains those changes

13. Where to look to prepare • Old assignments and notes • Text chapters 5-8 • Specific pages 178-179, 198-199, 228-229,262-263

14. Electricity! • C5 – explain the production, transfer, and interaction of static electrical charges in various materials • Using illustrations, demonstrate interactions between charged materials (positive, negative, neutral)

15. C6 – explain how electric current results from a separation of electric charge and the movement of electrons • Distinguish between • Potential and kinetic energy • Static and current electricity • Define current in terms of the amount of electric charge passing a point in a given time interval

16. C7 – Compare series and parallel circuits involving varying resistances, voltages and currents • Draw circuit diagrams using appropriate symbols that are properly placed • Perform calculations using Ohms law • Differentiate between series and parallel circuits in terms of • Current (SASS) • Voltage (PVSS) • Resistance (total resistance increases in series, decreases in parallel

17. C8 – relate electrical energy to power consumption • Define power and energy • Energy consumption – cost calculations given power, time and price of energy • Understand the significance of conservation and methods by which we can conserve energy • Understand modern developments in electricity conservation including EnerGuidelables, electrical vehicles, smart meters

18. How to prepare • Electricity unit worksheets / handouts / notes • Limited materials in the text (not used for instruction), good content from Ch 9-11 • Pages 296-297, 330-331, 356-357
