Review of metric system. Set up like a lab, but includes the basics...
Transcript of Metrics/Measurement
LENGTH LAB
How Many Thumbs
1. Measure the HEIGHT of your LENGTH LAB sheet of paper.
2. Write down how many thumbs it took on the BACK OF YOUR PAPER
3. Ask your partner how many thumbs? Do you get the same answer? Why or why not? EXPLAIN ON THE BACK OF YOUR PAPER
Science make two types of observations. We learned
that they are _______________ and
_________________. Because we can’t always trust
our eyes, it is best to always use
____________________ which uses numbers. In
science class, we will be using the ____________
system to to take the length, volume, mass, and\
temperature of different objects. This system is easy
because it is based on the number ___________
38
BACKGROUND INFORMATION
The distance from one point to another.
METERS
LENGTH
KILOMETERS METER
CENTIMETER MILLIMETER
1. Measure these lines using a metric ruler!
2. Write your measurement next to the line.
3. Remember to include the unit as part of the measurement. Without units, numbers are meaningless. THEY NEED A LAST NAME!!
1.TAKE OUT YOUR LENGTH LAB-Measure the lines on 1-5-Complete the Using Your Noggin Box
2.Get out COLORS: green, yellow, red
3. Graph your grades4.Get ready for NOTEBOOK CHECK
WARMUPDO NOT WRITE
JUST FOLLOW THE DIRECTIONS

a. The distance from city to city km m cm mm
b. The height of a flagpole km m cm mm
c. The length of a lady bug km m cm mm
d. The length of a pencil km m cm mm
SUMMARYWhat did you learn about in
our length lab
1. Was measuring in METRIC (meters) better than using USA (inches),
2. WHY DO WE NEED TO HAVE EXACT MEASUREMENT (remember How many thumbs)
Objective:I will review length and complete my lab
and practice another measurement called volumeWARMUP #9

METER LENGTH METRIC ENGLISH
• In science class, we use the ______________ system. __________ is the distance from one point to another. The metric unit for length is _________.
2 The best unit to use if we were measuring the length of a battery is km m cm mm

METRIC GRAPHIC ORGANIZER
is the amount of _________ an object takes up
liters
VOLUME
38
1. Add liquid to the graduated cylinder
2. Get eye level with the liquid in the graduated cylinder
3. Read the BOTTOM of the MENISCUS
4. Determine how much liquid is in the graduated cylinder
IRREGULAR SHAPED OBJECT1. Fill a graduated cylinder with a certain
amount of water2. Write down the STARTING amount 3. Add the object and note how much the water
went up in the cylinder. This is the ENDING amount
4. Subtract the ENDING-STARTING amount. This equals the VOLUME OF THE OBJECT
Water Displacement
(12 ml)
(20 ml)
20-12 = 8 ml
L
H
W
REGULAR SHAPED OBJECT
1. Measure the LENGTH (L)
2. Measure the WIDTH (W)
3. Measure the HEIGHT (H)
4. Multiply L x W x H= VOLUME
5. Remember numbers need a LAST NAME!! (cm3)
6. 3 cm x 3 cm x 3 cm = 27 cm3
L
W
H
Objective:I will practice finding the volume of
regular and irregular objects
WARMUP #10
FILL IN THE BLANKS
liter volume graduate cylinder
1. __________ is how much space an object takes up In science class, we use a ___________________ to measure volume. The unit for volume is _________
2. Draw a box that is L=6, H=3, and W=3. What is the volume.
41
Regular Object
Can you find the volume of this box??
6 cm
3 cm
3 cm
V = L X W X H

Irregular Object
20 mlWhat is the starting volume
28 mlWhat is ending volume
Displaced volume =28 ml- 20 ml = 8 ml
Volume of rock = 8 cm3
STARTING ENDING
What is the volume of the
rock
How Many Drops
Problem: How many drops of water will it take to equal 1 milliliter?
Hypothesis: I think it will take__ (you make a guess)__________________
How Many Drops???
Average = Add your boxes up and divide by 3

OBJECTIVE
I will learn how to find the mass (stuff) of an object using a triple beam balance
WARMUP #12
Which OBJECT HAS MORE MASS or STUFF in it
A MOUSE OR A ELEPHANT

WARMUP #13a) What is the total mass? b) Where should the riders be?
OBJECTIVE
I will find mass (stuff) of an object using a triple beam balance and review in metrics
packet

What is the total mass? Where should the riders be?
172 g

MASS LAB
1. Calibrate the Balance. Make sure it is at ZERO
2. Table 1: Practice with the KNOWN mass 50, 20, 10, 5, and 1 grams. BE COMFORTABLE!
3. Table 2: Measure the mass of the 5 objects. Once Mrs. DuBose checks and you have the right answer, your group will get approval and may choose 2 items each to find the mass of
4. Guess the mass and then actually weight it
44
Warmup #14: What is the mass?
OBJECTIVE
I will use a thermometer and stopwatch to measure time and temperature and review
in my metrics packet

How does the starting temperature of water affect how quickly its temperature will change when 3 ice cubes are added?
Hot or Cold Water
Temperature Change • 3 ice cubes• 100 ml of water • same time period
If ___________________________, then _________________________
Procedure:• Place 100 mL of water into the 250ml beaker. • Place the thermometer in the beaker and take the
STARTING temperature of the water record in the data table at 0 minutes.
• Use the tongs and place 3 ice cubes in the water and STIR.
• Record the temperature every 30 seconds for 5 minutes.
• Once done repeat with HOT WATER gotten from Mrs. DuBose. BE CAREFUL
