- Your timeline visual representation is DUE and will be presented on Monday. No lates will be accepted.
Have a great weekend!
This week we have been talking about physical and chemical reactions. Students should be reviewing their notes to ensure that they know the difference between each, and they can list physical and chemical properties of matter. Today we started a project to learn about evolving theories of matter. How did we learn about the atom? How did our ideas about the atom change over time? Students have been assigned an important person or era to create a visual representation on and will be presenting their work on Friday. All students work will be put together and presented in a visual timeline!
Today we started work in reflections and line symmetry. The notes are attached! We also talked about and took notes on the physical properties of matter. Grab the notes from a friend if you missed it!
Just a reminder that your graphic organizer on the classification of matter is due on Monday. No exceptions!
Have a great weekend!
Here is what we learned about particle theory:
1. All matter is made of extremely tiny particles
2. Each pure substance is made of just one kind of particle
3. Particles are attracted to each other
4. The space between particles is much bigger than the particles themselves
5. Particles are always in motion
6. The temperature of the particles controls how much they move about
Attached are the math notes from today. If you missed it, you can visit homework hotel or see me during nut break, lunch, or after school
I've also posted the textbook pages for our new chemistry unit
Happy new year! Today we start a new science unit: Matter and Chemical Change. We will be learning about physical and chemical changes and reactions, the periodic table of the elements, the language of chemistry and so much more!
But first, what do you remember about WHMIS??
School is back in session on Monday, January 8th. See you then!
We will be starting some math work in reflections and symmetry. If you have a pad of grid paper, it will come in very handy!
See you in a couple of weeks :)
What should I study??
- dangers of space exploration: physical, mental
- challenges of space exploration: propulsion, bringing resources
- environmental hazards in space: solar radiation, meteors, fluctuating temperatures
- space junk
- geocentric and heliocentric
- astronomical units and light years
- azimuth and altitude
- Newton's 3rd law
- what does it mean when we say space is a vacuum?
- important features of the space suit
- optical telescopes: refracting and reflecting (study the diagrams)
- Doppler effect, red-shifting, blue-shifting
- triangulation and parallax
What do you really need to know after today's lab?
Parallax is the apparent shift in position of a nearby object when the object is viewed from two different places. For a quick example of parallax, hold out your arm and stick up your thumb. With your right eye closed, look at an object on the far wall behind your thumb. Now, look with your left eye closed. You will notice how the background to your thumb appears to have moved.
Astronomers use a star’s parallax (that is, its apparent shift in position relative to the background stars) to determine what angles to use when they triangulate the star’s distance from Earth. When triangulation calculations are made, the longer the baseline, the more accurate the results. The longest baseline we can use from Earth is the diameter of Earth’s orbit. This means that measurements must be taken six months apart to achieve the maximum baseline length.
