HAPPY SPRING BREAK!! Be safe!
Remember to maintain social distancing and be safe! There will be more information here once we get it from the district. Miss you guys!
Okay all Ms. Rogers' Science 9 students, here we go with the online learning. I'll be putting up one new assignment every week at the start of the week, then sending you a google form (like the first one I sent to make contact with you to ask if you could access my website and if you brought home your textbook) on Thursday of every week to see if you've done the work. If you have questions about any assignment, you can email me at jrogers@deltasd.bc.ca and we can either email or maybe set up a virtual meeting with anyone having problems with a topic. IF YOU DO NOT HAVE YOUR TEXTBOOK AT HOME, USE THE LINK AT THE TOP OF THIS WEBSITE PAGE to download a pdf of all the chapters.
Lesson #1: April 14th: Please DO NOT submit your completed work to me; I will ask you, as a homework check, to fill in a google form that I will email out to you to your deltalearns.ca email on Thursday of each week to let me know whether you have done the assigned work and if you have any questions. When I DO assign work for assignment marks I will let you know about how to submit to me. See below for Lesson #1. Click on the arrow in the top right corner to view it.

Note that if 2 electrodes are made of the SAME metal, in our example on the google form, copper, then neither electrode has a greater or lesser affinity for electrons, so neither "wins" the tug of war for the electrons, therefore no electrons get accumulated on either terminal, so NO potential difference can be generated. ALSO, having seen the photo of different batteries such as D, C, and AA all having the same voltage rating of 1.5V should tell you that the physical SIZE of the battery does NOT dictate the amount of voltage it has!
Here is LESSON #4: May 4: use the link BELOW to access it: PLEASE do NOT submit this to me, I will send out an email on Thursday with a new google form for you to fill out. Lesson #4 is due by 5 pm Friday, May 1, by submitting the google form whose link will be sent out to you on your deltalearns. ca email on Thursday. This is a HARD deadline, no late assignments will be accepted.

NOTE: Please STOP PLAGIARIZING googled answers for the google form questions that you DON'T understand!! The questions on the google form are entirely from the lesson you just did!!! IF YOU ACTUALLY WATCHED MY VIDEO, you should have seen that batteries connected in series give additive voltage, so for four 1.5 V batteries (and you always assume they are giving you the proper voltage) 4x1.5=6V. Batteries connected in parallel give the voltage of a single battery, so four 1.5V batteries in parallel would give 1.5V. The advantage of having them in series is you get higher voltage to run the circuit. The advantage of batteries in parallel is that they are all only using part of their energy at any one time so they last a lot longer. PLEASE DO NOT USE INFORMATION YOU DO NOT UNDERSTAND in your answers!!!!
RESULTS OF LAST WEEK'S SURVEY FOR MS. ROGERS' CLASSES ARE IN!!!!
# of responding students finding the workload TOO HEAVY:
- Biology 12 -------- 2 out of 48
- Science 9 ----------6 out of 95
- Science 8 ----------4 out of 25
AND SO, TO PUT OUT THE FIRE (??), ADMIN HAS ASKED US TO LIGHTEN THE LOAD THIS WEEK!!!!! See below for this week's lesson!

Results from last week's survey are in: most of you are fine with the online lessons in this course, some of you finding the content tougher without a face to face explanation and ability to ask questions on the spot. That's to be expected I think, that's why there are still bricks and mortar schools in the world! Some of you would prefer that I be on google classroom, but I won't be switching over to it since I have only a month and a half left of my career. Next school year, I believe all DSS teachers will be asked to use it for consistency for students. Some of the juniors said they don't like long videos, so no more Bill Nye! Some of the 12's asked that I put the google form survey up with the lesson on Monday, so I will do that, and also send out a reminder on Thursday. Also for the 12's, for those of you finding it hard to get the school work done because you are working full-time, I sympathize if you are having to work to support your family, but remember that you are still in school, and school is still meant to be a full time commitment! This is your graduating year! And lastly, if you have questions, just email me at either my First Class email or my deltalearns. ca email and I will answer you!

NOTE: the error in the drawing I noticed was that the hose seemed to be floating in mid-air! For second question on the google form, a light bulb turns on immediately when a switch is closed in a circuit NOT because electrons travel fast, they actually don't really travel fast at all, check out the Did You Know on p. 283: on average, electrons travel only about 0.5 mm per sec! From the lesson, reading the text p. 283, the wire is made of copper atoms, and already has electrons all the way along it, so when the first ones leave the battery, ALL the electrons are pushed by the electrons behind them in the entire circuit.
Here is LESSON #6: May 25-29: use the link BELOW to access it. PLEASE do NOT submit this to me, use the google form survey below. Lesson #6 is due by 5 pm Friday, May 29. I'll put the answer key out on the weekend.

Use the link ABOVE for the answer key for Lesson #6
Remember that CURRENT is the number of electrons, huge numbers of them fitting across the diameter of a wire, that pass a certain point in the wire every second, so think of current as the electrons flowing. Think of VOLTAGE as how much energy each electron carries that it got from the battery. Imagine each electron carrying a backpack of energy. If there is one 1.5 V battery in the circuit, every electron has 1.5 volts of electric energy to spend on the loads in the circuit. And the electrons have to spend ALL of the energy in their backpacks before they return to the positive terminal of the battery. If electrons only have ONE lightbulb to go through, they spend ALL their voltage on that. If they have 2 lightbulbs to go through, they have to spend part of their energy on each of them, so voltage gets divided up. Current is lower when there are 2 bulbs compared to 1 bulb because electrons slow down on their way through any resistance, and 2 areas of resistance slows the current down more than one.

Note that a DIMMER SWITCH, as explained in the google form questions, has a variable resistor in it. Remember from previous lessons that DIMMER light bulbs meant LESS CURRENT, as show on the ammeter in Activity 8-2D in Lesson #6. To get LESS CURRENT, you need MORE RESISTANCE. So increase resistance to get less current to make lights dimmer, end of story.
