Read section 8.2 in the text. Complete the activity 8-1B on p. 352. Due next class.
Be sure to finish 9.2 in the workbook, if you haven’t already (assigned before Spring break).
Do activity 9-2B on p. 326 (chart and 2 questions, only) for homework. Due Friday (2-1 and 2-2) and Monday (1-4).
Finish the power and energy questions given in class (from BC Science). Be sure to follow the steps we used in class.
In case you didn’t finish in class, the last few questions are below.
4. What is the current through a 6.0 W bulb when it is connected to a 1.5 V battery?
5. (a) A 40 W bulb is connected to a power supply and draws a current of 0.75 A. What is the voltage of the power supply?
5. (b) IF the 40 W light bulb is replaced by a 100 W light bulb, how much current will flow through the 100 W bulb? (Hint: Use the voltage found in part (a))
6. What is the power, in watts, of an unknown device, if a current of 35 mA flows through the device when it is connected to 3.0 V?
7. How much energy, in joules, is consumed by a 120 W light bulb if it is left on for 15 mins?
8. How much energy, in joules, is consumed by a 1400 W hair dryer if it is used for 10 mins?
9. How much energy, in joules, is consumed by a 200 W stereo if it is left on for 4.0 h?
Be sure to bring a calculator (cell phones cannot be used as calculators), textbook and workbook.
Assigned before Spring break: Read 9.2 in text and do 9.2 in workbook.
Review clam anatomy and make notes/diagrams for your reference (not for handing in) in preparation for clam dissection.
Please ensure you have researched Phylum Mollusca and taken notes on their classification, body plan, respiration, excretion, reproduction, digestion, motility, nervous system, circulation (internal transport) and ecological importance. Block 2-3 Molluska Jigsaw (note) can be accessed here.
Work on mollusk handout and bring all clam/mollusk paper to class.
Read section 8.1 and be ready to discuss.
Be sure you have finished 9.2 in the workbook and 9.2 reading in the text.
Continue researching segmentation, coelomates (main points) and look up synapomorphy and plesiomorphy. Watch the Crash Course video on Complex Animals (Youtube).
Explain (briefly) the following terms/concepts:
vector quantity, scalar quantity, speed, velocity, acceleration, force, gravity, friction, position, distance, displacement.
Research series and parallel circuits and read the textbook section 9-1 in order to be able to answer questions 7 in the workbook (p. 130). Explain your answer using both a diagram and in words.
