How Do You Measure Up? 10/13/15

Key Question: What does Mass, Volume and Distance measure?

Initial Thoughts:

Evidence 1: Notes and Measurement Lab

Listen to the notes first.There are 8 stations. Read the instructions and record your answers in your journals.

MAKE SURE TO WRITE DOWN THE NUMBER OF THE STATION

SI Measurements(also known as “metric system”)

• “SI” stands for “System International” or “International System of Measurement”

• What about it?

– Common Language for scientists– Based on units of 10– Multiply or divide to go up or down

when converting units– Prefixes determine “how much” of a

unit

Important BASE units to remember:

METERS = m (measures distance or length, how long an object is or how far it is between two points)

• Measure with ruler/meterstickruler/meterstick

LITERS = L (measures volume — how much space something takes up)

• Measure with graduated graduated cylinder/beakercylinder/beaker

• Or with a rulerOr with a ruler (length · width · (length · width · height)height)

GRAMS = gg (measures mass-all the matter an object has which is different then weight)

• Measure with triple beam triple beam balance/scalebalance/scale

oCELSIUS = ooCC (measures temperature)

• Measure with thermometerthermometer

Measuring Liquids• How many ml of water

is shown in the picture?

• Always measure from the bottom of the meniscus.

• Answer: 6.6 ml

Measuring VOLUME by displacement• Used to measure irregular or non-box shapes.

• When you can’t measure length x height x width

• 5.6 – 4.8 = 0.8 ml

Measuring Mass• What is the mass? Don’t forget to include

units!!!

Station #9

• Use your hand measurement from the Going the Distance lesson.

• Convert from centimeters to:– Decimeters, meters, decameters, kilometers

Evidence 2: Notes & Practice

• Listen and take notes

Important PREFIXES to remember:

k = kilo- (means “10001000”)h = hecto-(means “100100”)D = deca-(means “1010”) BASE UNIT (liter, meter, gram)

d = deci-(means “1/10” or 0.11/10” or 0.1)c = centi- (means “1/1001/100” or .01)m = milli- (means “1/10001/1000” or .001)

Easy way to remember the order of prefixes:

Practice

• 1 meter (think meter stick)• Equals 100 cm• Equals 1000mm

• Challenge: How many kilometers?• 1 meter Equals 1/1000 km

Triple Beam Balance

• Go to my SWIFT page. • Click on Links• Click on Triple Beam Balance Practice

Evidence contd.

• With your table partner, complete the bottom questions 1-10.

• Reminder: remember Participation. Everyone should be contributing.

Analysis Questions1. Name 2 different base units that could measure

the amount of water a fish tank could hold.

2. Why is the number 10 important in the metric system?

3. Why would the prefix “kilo” be more useful than “tera” (1 trillion)?

SummaryWhat did you think about energy in ecosystems

before this lesson?

What did you learn about energy in ecosystems from this lesson? (Minimum of 3 sentences!!!)

What are some further thoughts or questions you have about how to use the metric system?

Reflection:

Come up with your own Metric Mnemonic:i.e. Kids Have Dreams But Dreams Cost Money Kilo- Hecto- Deca- (BASE) Deci- Centi- Milli-

ORKing Henry Doesn’t Usually Drink Chocolate MilkKilo- Hecto- Deca- (unit) Deci- Centi- Milli-

Big Idea

• What is the big Idea of metric units & conversion?

• Metric prefixes are multiples of 10 and can be easily converted by moving the decimal.

Get the sheet by the door and glue it into your lab notebook.

Fill in the “guess” column

Today: Metric Olympics!!!

Goal: To test your ability to take accurate metric measurements for length, volume and mass.

Metric Olympics• You will work with a partner• Everyone must take measurements and fill

out their own data sheet• You must remain on task• It’s important that we are respectful of other

classes
