Science 10H: Blackbody Radiation (Mar 12)

Hi Everyone,

We investigated blackbody radiation from us and the stars in two aspects today: color and power. With higher temperature, blackbody radiation moves from infrared to visible light, so hotter stars are actually bluer, while colder stars are redder. We also found out about blackbody radiation from us. We emit in infrared and makes a few hundred watts of blackbody radiation.

Hi Everyone,

We made some pinhole cameras today, but unfortunately the Sun did not cooperate. We will try to use the pinhole camera some other day when it's sunny. 

The Sun has many elements on its surface, and hydrogen is the most dominant one. That's why we see so many different features when we look at the hydrogen by itself. I've revised today's slides so they make a little bit more sense. Here's the link to it:

https://docs.google.com/presentation/d/1vUQH0NjcLlrNDtxghy6qbp26NBJTV5ZGmtSXTbEyxws/edit?usp=sharing

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!

Mr. T

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.

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"!

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.

Hi Everyone,

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.

Mr. T.

Science 10 Block 2: February 8

Hi Everyone,

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. In the astronomy unit, we will learn about how much energy our Sun produces, and with the same equation, how much energy our bodies produce naturally at this moment!


What's to come:

1. 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).
2. Please keep your formula sheets so we can fill in more information in two weeks!
3. You will get all of your homework back before the unit test, starting with KE/PE worksheets next class.
4. The unit test is tentatively scheduled for Monday, February 26.

Hi Everyone,

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!

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.

Hi Everyone,

Hope we all enjoyed the lesson today. It's certainly interesting to know that Isabel and Kaleb are interested in astronomy. Astronomers know a lot about our universe even though we have explored so little of it: human have not even been to the next planet yet!

Here is the link to the slides shown in class today:

https://docs.google.com/presentation/d/1s63vo-EuoDh43UQ_gwgqv5CgweTXhi7R8DsVTfZpVRk/edit?usp=sharing

We will be working on how to calculate kinetic energy (energy of motion) next class. See you on Wednesday!

Mr. Tung
