1. What is the name of the system of measurement used by scientists?

2. Why is it important we all use the same system?

3. What is Burkholder’s Picture Policy?

Friday we took our first test in here,◦ If you passed the test with a 60% or higher you have the

OPTION to redo the problems you got wrong

BUT◦ If you got a 59% or below you MUST redo your test by

Wednesday or stay afterschool with me Wednesday. As well as you must have a parent sign your test

Let’s go over how to redo tests in here

On the back way I updated your grades so you can see what you are now getting in science with this test score in the computer

Taking Care of business

Today we are going to Learn about the basic unit for measuring length

THE METER

Meters

Meters are our base unit for measuring length or distance

The typical toolwe use to measure is a meter stick

ex. let’s see how to use one

If I am measuring something really small like the length of an ant, does it make sense to use a meter stick?

Meters

OR If I am measuring something really long like the distance from New York to Las Vegas, does it make sense to use a meter stick?

Meters

The metric system is based on 10s so if we are measuring something smaller we break the meter stick into 10 equal parts (decimeter), and if we have to smaller we break that into 10 equal parts (centimeter), and if we have to go smaller we break that into 10 equal parts (millimeter)

Meters

The metric system is based on 10s so if we are measuring something larger we put 10 meter sticks together to get Decameter. Then put 10 of them together to get a Hectometer. Finally put 10 of them together to get a kilometer.

Meters

Let’s practice a way to remember all of these different units…

Let’s Watch a Short Video


Now some of these you have heard of and have used, but honestly some of these we never really use.

Let’s look at some that we use more often

Meters

Meters One centimeter is

about the width of a large paper clip

•or the thickness ofyour fingernail.

Meters One millimeter is

about the thickness of your finger nail

Meters A meter is about the width of a doorway

Meters A kilometer is about six city blocks or 10

football fields.

1.6 kilometers is about 1 mile

Let’s start a metric poster in our notes

A car’s length

The tip of a needle

A football field

A book

A pencil point

A pencil’s lenght

What’s the appropriate tool to measure??

Distance from Here to Target

Height of your table

A piece of paper’s length

Bulletin board

A penny’s thickness

A penny's width

What’s the appropriate tool to measure??

Now let’s talk about converting metrics◦ Let’s say you measured a book and it is 18cm

long and you wanted to know how many mm that was, or how many meters that was. What we call this is converting units of measure

◦ Let’s do some of the board

Converting Meters

10 cm = ___________mm

30mm = ___________cm

3m = ______________cm

BUT WHAT IF WE HAVE DECIMALS????Let me show you another way to use the

saying and the staircase

Converting Units

Why is it important to use an appropriate unit of measurement when giving measurements?

Closing


1. What is the saying to remember all the units of a meter.

2. What is bigger a meter or centimeter?3. What is bigger a kilometer or a meter?

Today’s Standard:1.3 - The student will use SI units for measurement.

Remember if you did not pass the test on Friday you MUST get your parent to sign your test and you must redo the problems you got wrong by Wednesday or you have detention after school with me.

If you passed your test but you want a better grade on your test you have till Friday to redo and turn into my basket.



Let’s watch a short video


Let’s review ◦ King Henry Died By Drinking Chocolate Milk◦ Kilometer, Meter, Centimeter, Millimeter◦ Converting units worksheet on the back of your

metric poster

Today we are going to Learn about the basic unit for measuring mass

THE GRAM

Grams

Grams are our base unit for measuring mass

The typical toolwe use to measure is a triple beam balance


Grams

A milligram weighs about as much as a grain of salt.

Grams

1 gram weighs about as much as a small paper clip or an m&m.

1 kilogram weighs about as much as 6 apples or 2 pounds.

MassBase Unit: GramsMeasurement Tool: Triple Beam BalanceExamples:mg-raindrop or an ant or a grain of saltcg-eraser on a pencilg-paper clip or m&mkg- a book like a dictionary _____ ____l ___l ___l ___l ___l___l

Let’s review our poster

Let’s review the sizes of the unit meters

Now let’s compare that to the sizes of grams

BIG DIFFERENCE!

Let’s review

Now here’s the good part converting grams is the same as converting meters

1 a.61 cg = ______ g 1 b. 16.899 dg = ______ mg 2 a.10.98 hg = ______ mg 2 b.91 cg = ______ g 3 a.8 cg = ______ dg 3 b.2,263 mg = ______ dag 4 a.1.23 dag = ______ mg 4 b.856 mg = ______ dag 5 a.5 hg = ______ kg 5 b.1.625 g = ______ mg 6 a.1 dag = ______ hg 6 b.1.4 dag = ______ dg

Converting

Give an example of something that has the mass of a g, mg, kg.

Closing


1. Give an example of something that is the length of a meter, cm, mm, km.

2. Give an example of something that has the mass of a g, mg, kg.



If your redo test is not in my basket by the end of the school day I expect you here at my detention after school


Today we are going to Learn about the basic unit for measuring Volume

LITERS

Liters

Liters are our base unit for measuring Volume

The typical toolwe use to measure is a graduated cylinder


Liter

1 milliliter is about the amount of one drop

Liter

1 liter is half of a 2 liter bottle of Coke or other soda

A kiloliter would be about 500 2-liter bottles of pop

Or the amount of water in a bath tub!

Liter

Let’s review what km, m, cm, mm look like

Let’s review what kg, g, mg
