Science 9H: Asexual Reproduction Pros and Cons
Hi Everyone,
Today's presentation gave us some thoughts about the pros and cons of asexual reproduction. Even though asexual reproduction produces offsprings quickly with identical genes, it is also limited by such. Read your T-chart notes for reviews on those reasons.
Here is the link to the presentation slides today:

Science 10H: Introduction and Solar System
Hi Everyone,
Today we took a journey of the planets through our lab, as well as the causes of the Moon Phases on Earth. It is important to remember that moon phases are caused by us looking at different portions of illuminated surface. Here are some extra worksheets that might help you understand.
Try drawing phases of the moon out!

Science 9H: Onion Root Tip Observation
Hi Everyone,
Some groups got all of the phases for mitosis -- great job. Everyone had a chance to see through two stages of the mitosis, please make sure you have sketches for at least two stages of the mitosis finished.
In addition, please finish the questions on the back of the instruction sheet, as I will be collecting them together with the observation sheet.
If you have any question about the assignment, send me an email. I will get back to you.
Have a great weekend,

Science 10H Block 2: Heat Transfer & Exam Review
Hi Everyone,
We've talked about the two kinds of heat transfer today: conduction and convection. Here are the notes that I made before today's class on these topics. If you need the diagrams, come see the transparent in the classroom!
https://docs.google.com/document/d/1y_oGkKJdmXdZHWSwtR6MDK36xwra2vDYY73iheMJylY/edit?usp=sharing
For Monday's exam, think about the following materials:
1. Kinematics: distance, time interval, displacement, speed, velocity. Which ones are scalar/vector; how to calculate them; how are they related from one to another.
2. Kinetic energy: depends on velocity and mass. Its unit is Joules. You will be asked to do calculation.
3. Potential energy: depends on mass, gravity, and height. Its unit is Joules. You will be asked to do calculation.
4. Lab: What we did in the free fall lab. What is the purpose? What did we measure? How did we measure (ticker tapes)? Why are potential energy and kinetic energies different? (sound/heat + human error of pulling)
5. Temperature and thermal energy: thermal energy is the sum of particle kinetic energy, and temperature is the average of particle kinetic energy. Conduction and convection: how are they different? what are some examples of them?
If you have any question, please let me know!

Science 9H Block 8: Forms of asexual reproduction
Hi Everyone,
Thank you for participating in station learning. I hope you've learned about various forms of asexual reproduction. Don't forget: all forms of asexual reproduction produce offsprings that have the same genes as their parents!
We will work with microscopes on Friday to see mitosis in action. Onion root tip experience a lot of growth (it's the tip), so lots of mitosis are happening. Don't forget to do your picture dictionary of the microscope, and write one-sentence descriptions on the function of each component! This is important to ensure that we can find all stages of mitosis in the plant slides.
Have a good night!

Science 10H Block 2: Temperature
Hi Everyone,
I hope the lessons are a little bit more clear today. One thing that we mentioned but didn't go into the details has to do with Kelvin. Dora mentioned last class that it makes no sense to use a negative temperature; does that mean that an object with negative degrees Celsius have negative kinetic energy? That is a very good idea, which is why scientists prefers the use of Kelvin, which uses absolute zero as the reference temperature. At absolute zero, particles do not move, so that they indeed have no kinetic energy. Using Kelvin ensures that there is no "negative temperature", thus no "negative kinetic energy"!
Here is the link to today's definitions:

Science 9H Block 8: Mitosis
Hi Everyone,
Mitosis is important for it produces cells that allow us to grow. It is also important for fully-grown adults to repair dead and old cells. There's lots of mitosis going in our skins, because skins are in contact with the environment and wear down quickly. Mitosis helps the skins to restore the dead cells!
We're going into the lab on Wednesday to learn about asexual reproduction, where one life produces lives of exactly the same genes! Asexual reproduction is all around us without us noticing. Remember to form groups of 3. You will be in the same group until three weeks after the spring break.
Enjoy your evening.

I'm very impressed by how well our class have been doing. Energy is a big topic, and our journey exploring won't be limited to this unit. In astronomy unit, we will explore more forms of energy, namely in the form of radiant/light and nuclear potential energy. We will also cover more material after the lab is done next week. Thanks for sharing your thoughts on how this class is going with your journal!
Have a great long weekend.

It was very fun reading your journals! Thank you for putting so much thought into them. Many of us want to learn about light and solar energy.

What's to come:

What's to come:
- We will learn, in detail, two more forms of energy: thermal energy (we will learn how to quantify it), and electrical energy (components of our electricity grid and cell phone batteries).
- Please keep your formula sheets so we can fill in more information in two weeks!
- You will get all of your homework back before the unit test, starting with KE/PE worksheets next class.
- The unit test is tentatively scheduled for Monday, February 26.

The first stages of SpaceX rockets are reusable. They are first returned to a "landing zone" near their launch site, or returned to a moving platform at sea. Returning the first stage at sea actually saves fuel, because by the first stage separates from the rest of the rocket while they are above the sea!

Grouse mountain is 1127 meters above sea level, and the Grouse grind's base is 274 meters above sea level. How much energy do you (50kg) gain in potential energy by hiking the Grouse Grind?
A.4.3*10^4 J
B.5.6*10^4 J
C.4.2*10^5 J
D.5.5*10^5 J
Mark Watney, the protagonist in the movie the Martian, was threw into the air by a broken antenna on Mars. Mars has a smaller gravity (3.7 m/s^2) than the Earth. If his total mass, including his suit, is 100 kg, and he was threw 20 meters into the air, how much potential energy did he gain?
A.2000 J
B.3700 J
C.7400 J
D.19600 J
It took you 1 hour to hike up Grouse Mountain. Supposed that you have gained 420000 J of potential energy during this time. What is your average power during the hike?
A.117 W
B.7000 W
C.8400 W
D.420000 W

Science 10 Block 2: February 2
Hi Everyone,
Other than the Wooden Roller Coaster, many of the rides at PNE, including Hellevator, manipulate the conversion between potential and kinetic energy to give riders the thrills.
Here is the link to today's notes:

Snow is not on the ground often in Vancouver, but snow can be found on the mountains right next to us. The Lions are a set of peaks from the north shore, visible from downtown. They are about 1600 meters above sea level. For 1 kg of snow on top of the Lions, how much more potential energy do they have, as compared to at sea level?
A.9.8 J
B.1698 J
C.7840 J
D.15680 J
