2
Today’s Planner: Measuring a Playhouse
Qualitative & Quantitative Quiz tomorrow
3
Today’s Goal: I can use the correct tools to gather and collect data.
4
Today’s Plan: Finish conclusion Metric System Make a Ruler Practice
5
WELCOME TO THE METRIC SYSTEM
The metric system is used to measure Length (meter) Mass (gram) Volume (liter)
6
King Henry Died By Drinking Chocolate Milk
base / 1000 KILO HECTO DEKA DECI CENTI MILLI base / 100 base / 10 base GRAM LITER METER 10 x base 100 x base 1000 x base King Henry Died By Drinking Chocolate Milk
7
What this means: One kilometer (km) is a little bigger than half a mile. A meter (m) is a little longer than a yard. A centimeter (cm) is about 1/3 (0.3) of an inch.
8
Why do you have to learn this?
ALL scientists use the metric system. Anyone understands this type of data no matter what language you speak. It’s WAY EASIER than the Standard System, which we use in the United States because everything is based on 10
9
LENGTH The base for length is METERS (m).
The tool that is used is a ruler. You could also use a measuring tape.
10
How to Measure We will NEVER use inches in science – only meters, centimeters, or millimeters. Line up the object with the 0, not the edge. The longer lines are centimeters (cm), the shorter lines are millimeters (mm).
11
How to Measure USE THIS SIDE NOT THIS SIDE

Real Practice Measure the items given to you (in cm) and find the area of each one.
51
How do we find the volume of things that aren’t cubes?
Displacement: The amount of water an object moves This type of volume is measured in LITERS. Most often we will use milliliters, or mL
52
Volume Volume is measured in LITERS (L).
The tool used to measure volume is a graduated cylinder. Most often we will use milliliters or mL. 1 mL = 1 cm3 = 1 cc (cubic centimeter)
53
Reading a Graduated Cylinder
Meniscus: the way water curves when in a tube
54
Reading a Graduated Cylinder
Understand what units the graduated cylinder is in Look at the bottom of the meniscus
55
Practice: How many mL are in the graduated cylinder?
What is the scale? (Meaning, how much is line worth?) Each line is worth 1 mL. 14 mL 90 mL 18 mL 42 mL 250 mL 43 mL
56
Finding the Volume After the object was placed in, the measurement was
After: 9 mL Before mL 2 mL After the object was placed in, the measurement was 9 mL Before object was placed in, the measurement was 7 mL
57
Practice: What is the volume?
38 mL AFTER BEFORE 38 mL - 32 mL 32 mL 6 mL
58

61
Practice: What is the volume?
AFTER 5.6 mL BEFORE 5.6 mL mL 4.8 mL 0.8 mL
62
Real Practice There are several stations around the room. You need to:
Find the “before” measurement. Find the “after” measurement. Subtract to find the volume of the object.
63

66
Today’s Plan: Check Homework Mass Instruction Mass Practice
67
TEMPERATURE Temperature is a measurement of the amount of heat in something Temperature is measured in degrees CELSIUS (⁰C) The tool that is used to measure temperature is a thermometer.
68
Water Boils Room Temperature Water Freezes
69
What is the temperature?
94⁰ C 65⁰ C 45⁰ C 27⁰ C
70
MASS Mass is the amount of matter (stuff) in an object
Mass is measured in the base GRAMS (g) The tool that is used to measure mass is a triple beam balance.
71
How to Use a Triple Beam Balance
72
How to Use a Triple Beam Balance
Double check that the balance mark is lined up. Place an object on the pan. Move the masses. START WITH THE SMALLEST MASS FIRST. If it is too small, go to the next biggest mass. Move the masses until the balance mark is again lined up.
73
Practice: What is the mass?
190.4 g 100 g + 90 g 0.4 g + =
74
Practice: What is the mass?
37.3 g 0 g + 30 g 7.3 g + =
75
Practice: What is the mass?
105.6 g 100 g + 0g 5.6 g + =
76
Practice: What is the mass?
536.8 g 500 g + 30 g 6.8 g + =
77
Practice: What is the mass?
290.2 g 200 g + 90 g 0.2 g + =
78
Practice: What is the mass?
263.5 g 200 g + 60 g 3.5 g + =
79
Electronic Scales Always make sure the scale reads 0 before you put anything on. If it doesn’t read 0, push the “tare” button. Never push on an electronic scale – you will break it.
80
Real Practice Measure each item around the room on the triple beam balance. Record your answer. Check your answer by measuring the item on the electronic scale at the front of the class. Return each item to the station you got it from.
