# A lighter subject

Today we will take notes on the whole EM Spectrum.  We have guided notes to help us follow but you should also take another look at the slides to make sure you didn’t miss something important!

We’ll also take another quiz on mechanical waves, and you’ll make your own EM Spec diagram.
Here is the Rubric on which you’ll be graded for the EM Spectrum Diagram.

Today we’ll  start by taking a Quiz over types of waves and the Doppler effect.  Then we’ll review the EM spectrum with a video from NASA.  Be sure to take notes on each of the classes of EM waves in the video and their applications to help you make a poster later.

For the last part of class,  and you’ll make your own EM Spec diagram as a color poster.
You can use the EM spectrum diagram from the blue textbook: p. 70-71
Use a strip of paper from the back bench and Mr. Siedler’s colored pencils.
You’ll be graded on neatness but will also need:
• 7 classes of waves
• Wave Frequency in numbers (Hz) along a line
• Arrows showing increasing energy
• Examples of the wave source or technology that uses that class of wave
• Objects about the size of a single wave
Here is the Rubric on which you’ll be graded for the EM Spectrum Diagram.

Answer the questions on this google form to get credit for the assignment:

# This Unit is Wave Better Than the Last.

This week we started on a new unit: Waves

First we started this unit with a set of slides and some demos describing waves in general.

After this we worked on measuring waves with our wave worksheets:
This is one,  this is the other.

The next class, we had some slides on how to change waves. Through changing the medium, or the relative speed of the source or what it bounces off of (Doppler)
Here are my slides:

And we ended with some homework calculating wave speed using the wave-speed equation.

Last, we used the computers to complete the assignment (HERE)
Using the Links in Mrs. Peterson’s Web-based Lesson here.

# This Energy unit is a real Joule!

Our next unit is Energy, we’ll begin with an over view of forms of energy, focusing on potential and kinetic. Then on to work and power, the Laws of Thermodynamics, and heat flow.

We’ll do some quick review Next we will spend some time interacting with the potential/kinetic energy exchange with the simulation here. The assignment that goes along with it is here.  or here

Work and Power:

Thermodynamics!

Heat Flow

We’ll do a little Lab on observing the 3 forms of heat flow

# Intro to physics

This is a new Unit for all of us (me too!).  Some of this I’m putting together as we go along so this post will be updated with activities and notes as we progress through the unit.

We started with notes on establishing how we talk about the motion of objects and defining scalar vs. vector quantities.

The notes are below

Next we had an activity where we explored these concepts and watched a Crash Course video about linear motion:

And on the third day of class we had a brief quiz and then started notes on accleration:

one of my favorite accelerators: the white zombie from Portland

3/15: Well I loved acceleration so much I had to do more here’s our lecture for the end of the week!

The Acceleration “quiz” assignment is here: answer all questions to the best of your ability,  checkout the cheat sheet on the last slide!

We’ve finished with describing motion and started with what causes motion: the force! After Spring break we will cover Newton’s 3 laws. we’ll do some reading in the text in case my yapping at you doesn’t do the job!

The Last set of notes for this unit! Newton’s 3 Laws of Motion!

and a crash course physics

# Bonding time pt.1 : totally ionic.

Our First Unit this semester is Chemical Bonds. — lasting attractions between atoms.

We started with a brief book assignment:  Qs from the ends of sections 1-1, 1-2, and 1-3 on Ionic and Covalent Bonds.  I’ve included a PDF copy of the book chapter HERE, (remember, just 1-2 + 1-3).

here are the slides for the first half of this unit:

We then covered some basics of bonding with some videos:

Then took notes and practiced creating Lewis Dot (electron dot) stuctures for the first time.  See the PDF of the notes linked here.

# Periodically Awesome!

We are finally getting to the key part of this unit.  Luckily an important scientist has reached out to this class to help us out.  Dimitri Mendeleev discovered a pattern in the elements and we will try to do the same.

Here is the message he sent:

Here’s the text of his assignment:

Good day fellow scientists. My name is Dmitri Mendeleev. I need your help! I believe I have seen a pattern in the elements! By creating cards for each known element and arranging the cards by weight and then looking for patterns in their character, I believe I have unlocked the secrets of the elements!Like any great scientist, I need others to confirm my findings. I have provided my data, but hidden the names of the elements. Please collect your data onto cards, then arrange by weight left to right, then look for a pattern. The elements can be arranged into families of characteristics up and down, creating a periodicity in the nature of creation.
Good luck dear scientists!

We watched some TED-Ed videos on Mendeleev and the periodic table:

Here and Here

And here are some notes on the Periodic Table

Lastly a crash course on the genius of the periodic table:https://www.youtube.com/watch?v=0RRVV4Diomg

# Time to get Atom.

We start our Chemistry learning about the nature and history of the ‘atom’ and Atomic Theory.

We’ll start by watching NOVA: Hunting the Elements which covers much of the content of the next 2 units Atomic Structure, Periodic Table, and Atomic Bonding.

Next, we’ll take some quick notes on the History of Atomic Theory to get us acquainted with the atom.  Here are the Slides :

And here is our reading on the structure of the Atom.

This TED-Ed does a great job of reviewing the History of Atomic Theory:

Lastly, here’s a modern reconstruction of the famous gold foil experiment that proved that most of all matter is actually empty space!

# Branches of Science

Our last set of notes is on the Branches of Science.  That is, the different forms of science that are practiced around many different subjects and questions.  This is by no means and exhaustive list, but is good start at the big branches. Here’s a link to some flash cards so that you can

here’s another with no definitions:
