Mrs. B's Physical Science Class

Warm ups and notes

2006-01-07T01:41:32Z

All information for the week of January 3rd-6th can be found here. Click the links to see what has been going on.

These are the warm ups for Wednesday, January 3rd, and Thursday, January 4th.

Write these down in the 1st section of your notebook and answer them.

Wednesday:

Motion
1: How do you know something is moving?

2: How can you tell when something is moving quickly or slowly?

Thursday:

Speed:
Speed = distance/time

A car is travelling 100 km/hour. How long does it take to travel 1000 km?

Notes for Wednesday:

Motion is the changing position of an object. When looking to see if something is moving, you use a reference point. For example, think about when you are riding in a car. Relative to the car, are you moving? Relative to the road, are you moving? Here's another example: what does the sun look like it does throughout a day? Does it look like it moves? Is it really moving or are we moving? This is relative motion. The appearance of something moving depends on what you are using as your reference point.

Notes for Thursday:

If I tell you that I walked around for three spandangles, what have I done? Do you know? Probably not, because it's not a term you are used to hearing for distance. If I tell you I walked around for three miles, you understand that. It's very important, when using terms describing a measured amount, to use things familiar to your audience. In science, there is the International System of Units, the metric system. This is because the U.S. is the only country that doesn't use it, and most science communities do. In order to communicate with other countries, we have to use their terms.

The ASU unit for measuring length is the meter. When we want to talk about smaller or larger lengths, we add prefixes to that basic unit. For example, there are 100 centimeters in a meter. This means the prefix "centi" is valued at 1/100th of a unit. There are 1000 millimeters in a meter. This means the prefix "milli" is valued at 1/1000th of a unit. There are 1000 meters in a kilometer. This means that the prefix "kilo" is valued at 1000 times a unit.

Notes for Friday:

Speed is how far something travels in a given time. This is most familiar to you when talking about how fast a car is going in miles per hour (or mph). As an equation, speed is calculated by dividing the distance travelled by the amount of time it takes to get there.

When travelling, you are not always going at a constant speed. For example, when going to Albuquerque, you don't go 75mph the entire time. And if you do, then I hope whoever is driving is REALLY good at pulling out of the driveway that fast. You start slow, go faster on the highway, then slow down again in Albuquerque. But, the speed for the entier trip is called the average speed and is found by dividing the whole distance travelled by the length of the entire trip. Let's look at an example:

Driving to ABQ, shopping, and back:

drive there: 1 hour - travel 100 km.
time at mall: 3 hours - travel (walking around) 1.5 km
drive home: 1 hour - travel 100 km

Total distance travelled: 100 + 1.5 + 100 = 201.5 km
Total time for trip: 1 + 3 + 1 = 5 hours

average speed = total distance / total time = 201.5km/5hours = 40.3 km/h

However, when you take the time to look down at the speedometer and check your speed, at that moment, you are looking at your instantaneous speed which is the actual speed at any given moment in your trip.

Questions and a table to help with your project

2006-01-06T04:29:08Z

First, I have made an Excel table to fill out to help you with the first part of your project, the Appetizers. There are multiple tables on one sheet, you only need one. You can download that file here.

Second, there were questions assigned in class today going over the following concepts:

reference points
direction
relative motion
changing position

Those questions can be downloaded here. There are two copies per document. Again, you only need one.

Review materials and quiz answers to help you make your cheat sheet

2005-10-06T06:05:40Z

Accidentally Left Out of your Notes:

Electric Properties Some substances conduct electricity better than others. This means that they allow electric charge to move through them easily. Copper wire is used to carry electricity because it is a good conductor. Materials that do not conduct easily, such as rubber and plastics, are used to block the flow of charge. With the proper equipment, scientists can test the electric conductivity of an unknown substance.

Vocabulary: Due tomorrow during the test.

Cheat Sheets: Use your notes, the quizzes, and any other information you have or I give you to make it. Remember, one side of a piece of paper, with anything and everything you want on it.

Projects:
Volleyball players and anyone going to miss part of next week – you will have to pick up your assignment early.

Everyone else: Your projects will need to be finished by Thursday of next week in order to present them to the class. No late projects or incompletes – do them, present them, get the grade.

Extra Credit opportunity

2005-09-10T17:40:23Z

Many of you blew off your lab report and are now struggling to be eligible for sports, activities, etc. I am giving you a one-time opportunity to make up your missing lab report. Here is what you are to do:

Find 5 common household items that are compounds, and find 5 that are mixtures.

Write a 1 page paper (if typed, it should be double spaced). In the paper name each of your five items. For the mixtures, also describe how they could be separated. Include your name, a title, and use complete sentences.

Chapter one vocabulary

2005-09-10T17:34:21Z

For the following vocabulary words, complete a vocabulary four-square. Feel free to use the dictionary to help you find definitions (although they are ALL in the notes)

These belong in the second section of your notebook and are due the day of the test (which will be sometime next week)

matter
mass
weight
volume
atom
molecule
element
compound
mixture
states of matter
solid
liquid

Section 1.1.3

2005-09-10T16:50:44Z

New notes are up.

It was a great class yesterday, and I really enjoyed the day. I appreciate everyone participating the way you did.

Alright, right-click/click here to get the notes. Right-click here for the lab.

Update: I passed out the WRONG lab during class. So because of that, there will be no lab quiz on Monday. I still need you to bring the jars to school though.

Chapter 1, section 2: Matter is made of atoms

2005-09-04T22:47:28Z

Power point notes can be found here. Either right-click to save, or click to open them in your browser window.

The lab accompanying this section can be found here.

The warm up (first slide) needs to be cut out and put in your first section of your notebook (or copied in). The questions go in the assignments. The lab is technically a mini-lab, and so you just need to print it out, do it, and answer the questions. No lab report is required for this.
