What is a DECENT living space?

In some prisons in the US, two inmantes occupy a 8 x 10 foot cell.  A college dorm room may be 12 x 14 for two people.  On the other hand, some people live in mansions of 10000 to 20000 square feet!

How much spece do people need in their shelters to have a decent, humane, life?  What do people need to be able to DO in their shelters?

Setting the Mood

You will need to practice your musical endeavor.  When you are ready, you will record your musical endeavor in the hallway using gcast.com.

Then, you need to include your music sometime in a shadow puppet show, which will be recorded using a camera.  Think about how you are going to set the mood (lights, penumbra, umbra, colored shadows, etc.) in your endeavor....a couple of videos are included below. 

Your instruments

Go to Flutomat to calculate the length of your pipes in centimeters

I need a post that details...

What your instrument will be
The materials you are using
Your song
Your partners
Your notes (e.g., C4, D3, etc.)
Your frequencies (261.31 Hz, etc)
Your wavelengths (.8 m, etc.)
The lengths of your note pipes or strings


Now, go to Flutomat to calculate the length of your pipes in centimeters

The role of the mouthpiece...

A mouthpiece is designed in such a way that it concentrates, or forces sound across a column of air.  How did you do this with the straw instruments you designed last week?

How do you make a kaleidoscope?

Yesterday, we worked with lasers and mirrors to reflect light. How do you think the pattern above was created?  How many mirrors would you use?

What is resonance??

Give examples of resonance using light and sound waves.

Videos on Electromagnetic Radiation Applications

Electromagnetic Radiation

Today we will be taking notes on the electromagnetic spectrum. You will need to take a link at the links here, here and here.

MAKE a drawing of the spectrum in your white notebook. Label 7 types of waves, where the longest frequency is, where the shortest frequency is, where the longest wave is, and the speed of light in a vacuum.

Draw a transverse wave and label parts.... crest, trough, amplitude, node, wavelength

List 5 ways we use electromagnetic waves each day!

Wednesday, 11/5/08

Today I am sick, so please follow these directions and COMPLETE THE BLOG POST BELOW.

TEST is postponed to Friday.

===
Use the computer or Google text to define the four following terms
frequency
period
amplitude
wavelength

(To use Google Text, text define _____(put the word in) and send to 466453)



You will be going a wave simulation. Work in groups of 3. The worksheet for today can be found here (print off an activity sheet for your group) and the actual activity can be found here I am looking for word observations, not a formula.

Looking at Data

Today, I want you to look at the data found at the link at the bottom of this post. Clicking on a county or state will give you more data. What trends do you see in the counties of Iowa (remember, Red is Republican, Blue is Democrat)? What trends do you see in national map? Take a look at Delaware, Clayton, and Buchanan counties, which make up the West Delaware school district. What does this tell you about how people in our school feel about the election last night?

You can find the link here

Inclined plane examples

Classify the following machines (lever, pulley, wheel/axle, screw, wedge, inclined plane):

a ladder

a circular staircase

a knife

a parking ramp

an axe

Which type of machine(s) above has the LOWEST AMA? Why do you think this is so?

More machines!

ANSWER PARTS 1 and 2 in your notebooks.


Today, you have the opportunity to work with another set of machines....doing the lab found here.


Go to here and try to identify the parts in the lawn mower. (Yup, you have to look around the site). Share the computers in the room.

When you get done, you can finish working on assembling your mousetrap cars. You will need to make a top drawing and a side drawing when you get done, which will be handed in.

Lab Groups:

Carissa, Tabitha, Bryan

Amie, Tea,

Tory, Carinda, Sonya

Kyle, Ted,

Ryan, Joe, Josh

Erin, Claire, Jenny

Summer, Lexi, Jordan

Devin, Jon, Dalton

What does a MA less than one do?

Here, we have two machines (3rd class lever and a wheel and axle) with an AMA less than 1.  What does this do for the racer?   How can we maximize this factor for the wheels?

Where are the machines!

Go to Edheads and pick a room in the house.  In each room, search for 10 machines.  Make a list of the machine (for example, maybe it's a pencil sharpener) and the simple machine type for your day's blog post.

Good luck.

What do machines do?

A can opener, a ladder, a pulley system, a come-along, a car.  What do machines help us to do in our daily lives?

List, if you can, an example of the following machines:

first class lever:
second class lever:
third class lever:
wheel/axle
pulley
wedge
inclined plane
screw

Monday tasks

1.  Today, you need to perfect your script for your video and record your mp3 on your cell phone using the license from GCAST.com   Remember, you must hit the # symbol after you are finished talking for the mp3 to record.  The mp3 must follow the events in the video, so I suggest you bring up the you tube page, run through your script a time or two, and then record.  This may be done individually, or in your groups of 2.

2.  Write five quiz questions that combine your vocabulary words with a specific sport.  Example question:  You are swimming in the pool, and the bubbles rise when you do a cannonball.  This is an example of  a) friction b) Newton's 3rd law c) mass  d) all of the above.  Make sure you circle the answer that you think is correct.  THIS MUST BE DONE INDIVIDUALLY.


At the end of the class period, turn in your definition sheet, your script, and your questions.

Today we get the opportunity to look for sport.

Step 1: Define what you believe a SPORT actually is.

Step 2: Use your book and your notes to define each of the vocabulary words (leave out center of mass, momentum, and work for right now)

Step 3: Find a video of a sport that you think uses Newton's laws. Copy the URL and paste in the comments section. It will look something like this: http://www.youtube.com/watch?v=NWE_aGqfUDs

Step 4: Go through and look for the time in the video where each vocabulary word is happening. Write this time down to the LEFT of the vocabulary word on your sheet. There must be at least 5 seconds between each vocabulary word. Describe what is happening in the video in the SITUATION column

Step 5: You are the sports announcer for this video, but you want to instruct people about the science in your sport. What comments will you make for each of situations you have described?

Where do you find....

Kinetic and Potential energy in each of the following.....

a) an athlete leaving the ground for a high jump

b) a pop fly on its way back down

c) an engine as the driver puts the hammer down

d) a cheerleader cartwheeling across the gym floor

When is mu (sticky friction) good?

When you are driving down a road, and you want to go 55 mph, what type of a mu do you want?  What about a mu on an icy day?  How does the mu in the middle of a gravel road differ from the mu on the edges?  How do you know?

What do you need?

So you are going to compete.  What type of shoes do you need?  Seriously, how pick three sports of your choice and comment on the type of shoes you want, and how they are different from another sport...

Good luck!

What's Gravity got to do with it, anyway?

This is a gravity map of the world.  The red spots indicate places where gravity is less powerful, and the blue spots indicate places where gravity is more powerful.  What is gravity, anyway, and what does it have to do with Newton's laws?

Balanced vs. Unbalanced

Think about the world we live in. It's filled with forces, some balanced and some unbalanced.

Give me three examples of a balanced set of forces.

Give me three examples of an unbalanced set of forces?

This is what Newton's 3rd law is all about.

After you do the lab today, you will need to come back and do a second comment. Tell me what was important about today's lesson.

Text me if you have a question. Linsay and Jordan can help you find any equipment, but it all should be in the labeled drawers...I'll miss you guys today. :-)

How to read instructions

Today, we will be working on # 1, 2, and 3 found on pp. 39 and the reading found on pp. 41-43 I will not be giving directions, because I want to see how well you can read and follow directions. One note: a pencil means you should write something in your journal.

Now, before you start, think about how you read a magazine. Think about reading a menu. Think about reading a set of directions on how to program your new ipod. How do these things differ? When you read a science book, what should you be looking for to help your understanding?

Answer in a comment, and then head back to the room.

Projectiles, Part 2

Assuming that you can throw all objects at a speed of 3 m/s, what effect will a changing angle have on the distance a projectile travels?

What about a changing mass?

Projectile Motion

Everytime we launch something into the air, it has properties of a projectile. Today we will be studying the properties of projectiles here

When you get done, tell me what you have learned about

a) angle patterns

b) object shape patterns

c) object shape patterns with resistance

You may work with a partner, but the blog post must be done individually.

Explaining a Newton to someone (10 pts)

A common quarter pounder weighs about 200g, with bun, or about 2N. 10 N is about 2.2 pounds. Come up with a scale of common objects that are an example of

1 N (.1 kg)

10 N (1 kg)


100 N

1000 N

10000 N

Football isn't always Football

Ask a European what football is and you can get tons of answers! Just check here for a look.

Pick one type of football (rugby, soccer, American Football, Aussie Football) or some ancient version and give me an example of when you would find inertia, a mass vs. acceleration relationship, a mass vs. force relationship, and a force vs. acceleration relationship. Explain two different frames of reference from which you can watch the game.

Forces around us

What variables affect the strength of a force? Consider forces in balance and forces not in balance. Are they the same or different?

Happy Early Out!

Well, guys, tomorrow is the first test. You need to spend at least a half hour studying. The test will include 10-15 multiple choice, and 3-5 short answer. I do not ask for vocabulary word definitions (that matching section), but I do use the vocabulary in the questions to help you think.

Topics covered on the test include:
reaction time
stopping distance (double the speed, increase stopping time by 4)
yellow light factors
what a d-t graph looks like for constant speed, acceleration, deceleration, and no motion.
strobe photos
how to avoid road hazards
equipment conditions
the questions in these blog posts...


Have a great day!

BM 2 Final Reflection

Write a 2-3 paragraph summary of what you have learned in this project about driving safety, and the factors affecting individual drivers. This should be a separate comment on the blog for each student. It should show me, without defining a list of vocabulary words, that you know what it means for a car or a person to experience velocity, speed, acceleration, reaction time factors, centripetal force, inertia, and equipment condition.

Please hand in the graph from part 1, the poster from page 2 (if you did it), your conclusions from page 3, and your conclusions from page 4.

Breakdown of points

Blog post 1: 10 points (that's the one below this post)
Graph: 20 points (you have done this)
Page 2 or Blog Post: 10 points (you have done this with your poster)
Page 3: 10 points
Page 4: 25 points (you need to make sketches of each)
Final blog Post: 25 points (that is this one)

BM2 Reflection--DO THIS FIRST

Your first task is to put together a driving manual. You can get the directions from me. Before you start, answer the following in 6-10 sentences:

Why do you think drivers need to know the fundamentals of speed, velocity, and acceleration while they are driving? What is the most common reaction time distraction YOU are likely to have? Answer in the comments

Nascar Tracks and Grooves

If you watch pro racing, you see those cars getting into a groove or two, with racers either driving at the top or the bottom of the track. You also see banking.

Why do these two factors matter?

How do you go around a curve?

What is the safe way to go around a curve?

What does it mean to bank a curve?

Who controls what?

So, there's yellow light ahead. You have jackrabbit drivers, overly cautious drivers, tired drivers, and poor brakes. You have single roads, double lanes, and overpasses...

What things can engineers control as they design the intersection? What things can you control?

Factors involving Yellow lights (20 pt)

How does the two stop light system in downtown Manchester differ from the light bank found in a city, where six or seven yellow lights in a row can be found? Give me a concrete example (Dubuque, CR, etc.) and your belief about what factors can change.


Text your group hypothesis to me regarding the use of the final yellow light simulation found on the last blog post. You need to explore safety and stopping mechanism, or stopping mechanism and flow rate in some way.

Write your whiteboard up with a procedure and a data table.


Dilemma Zone

Those Yellow Lights

Why do we need yellow lights?

Why do we seem to hit several lights in a row as either being green or being red?

Should we speed through yellow lights?

Blogsphere Land

Good morning! As you have probably guessed, I am not in the classroom today. I expect you to be doing a variety of things with your lab partners, including making a poster worth 20 points. The groups for today's poster are:

Group 1: Bryan, Ted, Tory
Group 2: Amie, Claire, Cari
Group 3: Tea, Summer, Jordan
Group 4: Dalton, Jennie, Kyle
Group 5: Ryan, Joe, Josh
Group 6: Erin, Lexi, Jon S.
Group 7: Tabitha
Group 8: Michael R

Assignment:
===============
1. The computer lab is not available today. Make due with the computers we have in the classroom, please. Go to here sometime during the day today and nominate a teacher that has made a difference in your life. It can be anyone in your life who has believed in your abilities and it is a chance for them to be recognized. Txt me when you are done with this step...just say, "This is _____--done."

2. You are traveling down a road and a deer runs out. Quick, what do you do? Click Here for a list of ideas (I have run several copies for the substitute, so please get one per group). Circle the three things that you think are most important.

Now, imagine you need to communicate this information to others in a VISUAL manner, with a maximum of ten words on the paper. Make a poster to explain how reaction time and equipment condition can help you to avoid the deer or minimize the collision. How would this be different if you were going around a curve at the time of the deer sighting? Hand this in before you leave today. Linsay and Jordan can help you find colored pencils or markers. After you do this, you may move back to your table

3. Read pp. 36 in your book and use the information to answer Q 1-8 on p. 40

4. Make a graph with speed on the x-axis and stopping distance on the y-axis for the picture at the top of this post(again, I have run several copies of this) and hand in with your name on it.



Thank you for being such a good sport! I really really appreciate it.

See you tomorrow.

Stopping Distance

As you double your speed from 20 mph to 40 mph, what do you think will happen to the distance you need to come to a complete stop? Estimate in terms of a number (E.G., 1.5 times, 3 times, etc.)

Give details of how you accelerate when:

a) you come to a stop sign
b) you go around a curve
c) you are coming onto an on-ramp for Hwy 20.

0 to 60 in how long?

One of the great bragging rights of some drivers is how fast they can accelerate, or how quickly they can get to 60 mph from a dead stop. This is accomplished by many factors: weight and transmission gear ratios.

Look up your dream car by going to a new browser window at http://www.caranddriver.com and look up a car you would like to own. Write the name of the car, the model, its front curb weight and the gear ratio for 1st and 2nd gears and record in the comment section.

Happy Friday!

How Fast can you stop?

Estimate how fast, in seconds, you can stop when you..

1. are driving 30 mph
2. are driving 55 mph
3. are traveling on an icy road
4. drive in the dark with your low beams on
5. travel on gravel
6. have a new car
7. have a heavy, loaded truck with a trailer full of cattle

What are the different variables you need to be concerned with? Why?

Be Honest

What things do you DO while driving that you know are distractions....or what do the drivers of the vehicles you ride in do? (Eating, putting on make up....etc.) Does this worry you? If the lab shows you a definite problem, will you change your behavior? Why or why not? I expect at least 4 sentences for this blog post.

What is an accurate measurement?

Think about all the things you measure each day--your weight, the volume of a soda in a glass, how far it is to school... How perfect must those measurements be to make you happy? For example, if your bottle of energy drink is only half-full when you buy it, is that good enough?


Now, think about driving. How close does the measurement from town to town have to be? What about the measurement of your speed, or of your stopping distance? Do those need to be perfect, or just within a range? Explain your ideas to me in 3-4 sentences in today's blog post.

Driving Factors

List three Critical Situations that occur during driving when someone needs to have knowledge of their own personal reaction time. How must you adjust your driving to account for that?

What type of learner are you?

Tell me about yourself. I want to know HOW you learn, based on the learning style inventory you took. I want to know what type of learning is AWFUL for you. I want to know WHAT hobbies or issues matter to you, so I can connect it to your learning in science. You have until Tuesday, 8/26/2008, to reply to this post. (Yup, that is why you needed a gmail account.)
