Metric Key Question: Why should the U.S. change to the metric system? Or not?

SI Units September 6, 2010, http://www.pfscience.com/2010/09/si-units/

In a science lab, we measure everything using SI units. What is SI? SI stands for the International System of Units, also just called the metric system. We say “SI” because we abbreviated SI from the French Système International d'unités. In the United States, most people still use the English Units (inches, Fahrenheit, etc).

Students often ask why we don’t just stick to using English measurements if everyone already knows how to use them. Actually there is nothing “wrong” with using English measurements except that the entire science community and most of the world uses the SI measurements. It makes communicating about scientific work more difficult if the units are not the same.

Why would scientists choose the SI measurements? It is because SI units are based on the number 10. For example…  Ten millimeters makes one centimeter.  Ten deciliters make one liter.  One thousand grams makes one kilogram.

Everything is divisible by the number 10, so to convert from one unit to another, it is simply a matter of moving the decimal place instead of having to do math calculations. The SI units are actually a more simple and elegant way of measuring.This is why you have to learn SI units, not because science teachers think it is fun to torture students. :-)

SI Units you should know:  Length = meters (m) Metric Key Question: Why should the U.S.  Mass = kilograms (kg) and grams change to the metric system? Or not? (g)  Time = second (s)  Temperature = degree Celcius (°C)

Metric Key Question: Why should the U.S. change to the metric system? Or not?

Refrain: Oh, metric. You’re the one. You make measuring way more fun. Based on ten. Let’s start again And go the metric way.

Once there was a bunch of giants Kilo was their name. They were all so huge and tall And no two were the same.

Now, Kilogram, he weighed a lot Kilometer was long. Kiloliter was big and wet. Each one a thousand strong.

There also were some tiny elves Who had the name of Milli. One one thousandth—they’re so small They’re just tiny and silly!

Now milligrams, they don’t weigh much. And millimeters are short. A milliliter’s a tiny drop Of liquid they report.

So, grams you may have noticed Are things you can weigh. Length is meter, liquid’s liter. That’s the metric way.

Math Skills Review: Texas A&M University (paraphrased)

Dimensional Analysis is a problem-solving method that uses the fact that any number can be multiplied by one without changing its value. It is a useful technique. Conversion factors may be made from any two terms that describe the same "amounts" of what we are interested in. For example, we know that

1000 millimeters = 1 meter

We can make two conversion factors from this information:

Write two conversion factors, if you know that 1 hour = 60 minutes.

1). 2.)

Now, we can solve some problems. Set up each problem by: 1. Writing down what you need to find with a question mark. 2. Then set it equal to the information that you are given. 3. The problem is solved by multiplying by the conversion factors so that only the desired units are present at the end. How many millimeters are in 2 meters? (show your work) (1) How many millimeters are in 6 meters? 1. ? mm 2. ?mm = 6 m 8 Measurement Mr. Switzer Name: ______Date: ______Hour______3. (see below)

(2) How many meters are there in 2500 mm

You may use dimensional analysis for any conversion (even with English Customary Units), as long as you know the conversion factor.

(3) If you know that 4 quarts = 1 gallon, then how many quarts is there in 9 gallons?

You can also string many unit factors together. (4) How many seconds are in 2.0 years? (hint: 365 days = 1 year; 24 hr = 1 day; 60 minutes =1 hr; 60 seconds = 1 min)

How many seconds are there in one day? (show your work)

Today, the more commonly found term is ruler. The dictionary defines both the term rule and ruler, so either can be used, and for this document I will only use the term ruler.

Metric Rulers Metric rulers are fairly easy to read. They deal with centimeters and millimeters only. You wont have to worry much about fractions.

Take a look at the following Metric Ruler.

The larger lines with numbers are centimeters, and the smallest lines are millimeters. Since millimeters are 1/10th of a centimeter, if you measure 7 marks after a centimeter, it is 1.7 centimeters long. English Rulers English rulers, are much more difficult to read. Mostly because they deal with fractions, which are a bit more dificult to learn. Take a look at the following English Rulers.

A ruler marked in 8ths. Every mark is 1/8th of an inch.

A ruler marked in 16ths. Every mark is 1/16th of an inch.

What is the length of the square below? (to the nearest 0.1 cm and to the neareast 1/8 inch)

inches How to Use a Triple Beam Balance September 7, 2010 By Science Teacher Leave a Comment http://www.pfscience.com/2010/09/how-to-use-a-triple-beam-balance/

The triple beam balance is one of the most basic pieces of lab equipment. It measures smaller mass quantities, and by that I mean something that you could pick up with your hands without a whole lot of effort. There is a limit to how much the triple beam balance can measure. The triple beam balance is simple to use. Even still, students often make mistakes both in using the balance and in reading measurements.

Measurement unit: gram 1 gram = 1/1000 kilogram

To use the triple beam balance:

1. Tare the balance first, which means to set the balance to “zero.” This is also called “zeroing” the balance. Scoot all the riders (the blocks that slide) from each of the three

12 Measurement Mr. Switzer Name: ______Date: ______Hour______beams to the farthest left first before doing anything else. Look at the pointer on the scale. If it is not lined up with zero, then turn the adjustment knob just beneath the pan until the pointer is even with the line.

Turn the adjustment knob until the pointer lines up with the 0 on the scale. This scale still needs more adjustment.

2. Place the specimen to mass on center of the pan. 3. Starting with the largest capacity beam (500 g), move the 500 g rider to the right to the first notch which causes the pointer to drop, then, move it back one notch, causing the pointer to rise. 4. Repeat procedure with the 100 g rider. 5. Slide the 10 g rider to the position which brings the pointer to rest at zero (pointer even with line)

How to read the triple beam balance: Add up each of the numbers on the rider pointers, and that is the mass of the specimen (in grams).

Specimen mass = 0 g + 100 g + 2.2 g = 102.2 g

What is the mass of the following specimen?______
