Monday 9/8 Write 2 QUALITATIVE observations and 2 QUANTITATIVE observations.

Today’s Planner: Measuring a Playhouse Qualitative & Quantitative Quiz tomorrow

Today’s Goal: I can use the correct tools to gather and collect data.

Today’s Plan: Finish conclusion Metric System Make a Ruler Practice

WELCOME TO THE METRIC SYSTEM The metric system is used to measure Length (meter) Mass (gram) Volume (liter)

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

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.

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

LENGTH The base for length is METERS (m). The tool that is used is a ruler. You could also use a measuring tape.

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).

Today’s Plan: Check Homework Qualitative/Quantitative Quiz Area Volume Practice

QQQ Write 5 Qualitative Observations about your skittles. Write 5 Quantitative Observations about your skittles.

Volume: the amount of space something takes up (3-dimensional) Area & Volume Area: the size of a surface (2-dimensional or flat) Volume: the amount of space something takes up (3-dimensional)

Area The Area of a rectangle (or square) is Length x Width 10 cm x 5 cm 10 cm LENGTH 50 cm2 WIDTH 5 cm Units for area are cm2

Playhouse Area Use the “Measuring a Playhouse” worksheet from last night to find the area of: The house The door The window

Real Practice Measure the items given to you (in cm) and find the area of each one.

The units for volume are cm3 Volume of a cube is LENGTH x WIDTH x HEIGHT 10 cm x 10 cm 10 cm LENGTH WIDTH 10 cm 1000 cm3 10 cm HEIGHT The units for volume are cm3

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

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)

Reading a Graduated Cylinder Meniscus: the way water curves when in a tube

Reading a Graduated Cylinder Understand what units the graduated cylinder is in Look at the bottom of the meniscus

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

Finding the Volume After the object was placed in, the measurement was After: 9 mL Before - 7 mL 2 mL After the object was placed in, the measurement was 9 mL Before object was placed in, the measurement was 7 mL

Practice: What is the volume? 38 mL AFTER BEFORE 38 mL - 32 mL 32 mL 6 mL

Practice: What is the volume? 12 mL AFTER BEFORE 12 mL - 8 mL 8 mL 4 mL

Practice: What is the volume? AFTER BEFORE 54 mL 46 mL 54 mL - 46 mL 8 mL

Practice: What is the volume? 22 mL AFTER BEFORE 22 mL - 12 mL 12 mL 10 mL

Practice: What is the volume? AFTER 5.6 mL BEFORE 5.6 mL - 4.8 mL 4.8 mL 0.8 mL

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.

Wednesday 9/10 Write the measurement: 36 mL 100 mL 14 mL 42 mL 1 2 3 4

Today’s Planner: Mass Practice

Today’s Goal: I can use the correct tools to gather and collect data.

Today’s Plan: Check Homework Mass Instruction Mass Practice

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.

Water Boils Room Temperature Water Freezes

What is the temperature? 94⁰ C 65⁰ C 45⁰ C 27⁰ C

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.

How to Use a Triple Beam Balance

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.

Practice: What is the mass? 190.4 g 100 g + 90 g 0.4 g + =

Practice: What is the mass? 37.3 g 0 g + 30 g 7.3 g + =

Practice: What is the mass? 105.6 g 100 g + 0g 5.6 g + =

Practice: What is the mass? 536.8 g 500 g + 30 g 6.8 g + =

Practice: What is the mass? 290.2 g 200 g + 90 g 0.2 g + =

Practice: What is the mass? 263.5 g 200 g + 60 g 3.5 g + =

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.

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.
