1
List homework in your agenda and turn in any late work see bin on window side counter. Predict: What is Matter? What are some of the components in the following items: loaf of bread, textbook, bicycle. * Can you break down any of the components even further? For example, one of the components of a book is obviously paper, but what are the components of paper? Record your thoughts in your science notebook/binder.

2
Warm-up Copy homework in agenda and pick it up from the table under the board. If not finished recoding information for the marble volume quick lab finish now (you may get the marbles and graduated cylinders if needed). Explain in your own words: What is volume? Draw a picture demonstrating you know what volume is using the correct metric units.

3
The Properties of Matter Essential Questions: What is Matter? What is mass? What is volume?

4
Objectives Describe the two properties of all matter. Identify the units used to measure volume and mass. Distinguish between mass and weight.

5
Quick Lab (1) Material Getter beaker Cup Paper towel (2) Discussion Leader BEFORE EXPERIMENT: What do you expect the paper towel to be like when it comes out of the bowl? AFTER EXPERIMENT: Was the paper towel like how you expected? Draw conclusions as to why the paper is the way it is? How can you support this idea with science. (3) Lab Initiator Wedge the paper towel in the bottom of the cup. All of the paper towel should be mashed in the bottom of the cup, with no edges sticking out. Place the cup upside down, perpendicular to the surface of the water. Do not tilt the cup or place it at an angle. Push the cup into the water until the rim of the cup touches the bottom of the bowl. Whole group: Countdown from 8. (4) Data Collector Describe the paper towel before and after the experiment.

6
Matter Matter is anything that has mass and takes up space. It’s that simple! Everything in the universe that you can see is made up of some type of matter. What do all these things have in common? They are all made-up of MATTER!

7
What is matter? Anything that has mass and takes up space Everything you see: boats, cars, people Some things you cannot see like air

8
Matter and Volume: The amount of space taken up, or occupied, by an object is known as the objects volume. Liquid Volume Liters (L) and milliliters (mL) are the units used most often to express the volume of liquids. Measuring the Volume of Liquids -We will use a graduated cylinder instead of a measuring cup to measure the volume of liquids. The curve at the surface of liquid is called a meniscus.

9
The space taken up by an object. Two objects cannot share the same space. Ex: Air and Water in the quick lab What is Volume?

10
Quick Lab Review Can water and air both occupy the inside of a cup at the same time? As a lab group, review the results from your experiment. Continue your discussion on why the towel was the way it was AFTER your experiment. Can you now use science to support why the towel was dry? Teacher shows what happens if there is a place for matter to escape.

11
What materials are used to measure volume? Graduated cylinders and beakers. Liquid in these have a meniscus curved water line Read the bottom of the curve for accuracy

12
Define and Draw the meaning of: Meniscus Define: Meniscus is the curve at the surface of liquid. Draw: Meniscus

13
What unit is Used to Measure liquid volume? Liters (l) and milliliters (ml)

14
Volume of a Regularly Shaped Solid Object The volume of any solid object is expressed in cubic units. The word cubic means having three dimensions. Volume of an Irregularly Shaped Solid Object You can measure the volume of any solid object by measuring the volume of water that the object displaces.

15
How is the Volume of a Regularly Shaped object found? Multiply the three dimensions of the object volume = length x width x height or v = l x w x h units used will be cubic meters (m 3 ) or cubic centimeters (cm 3 )

16
How is the volume of an Irregularly shaped object found? Water displacement method drop an object in a known volume of water (30 ml) the water level will rise (40 ml) The difference between the 2 levels represents the volume of the object: 40 – 30 = 10ml 1 ml = 1 cm 3 both can represent volume Almost always liquids in ml and solids in cm 3

17
Quick Lab In your Science binder, start a new page titled: Quick Lab. Finding the Volume of an Irregular Object. Using what you have learned today, set-up a quick lab that allows you to measure the volume of the marbles at your table. WHAT WERE YOUR RESULTS?

18
Mass and Weight Mass: Mass is the amount of matter in an object. Weight: Weight is a measure of the gravitational force exerted on an object.

19
Measuring Mass and Weight Mass Measurement: The SI unit of mass is the gram (g), but mass is often expressed in kilograms(kg) and milligrams (mg), too. Weight Measurement: Weight is a measure of gravitational force and is expressed in the SI unit of force, the newton (N).

20
What is the difference between mass and weight? videovideo Mass will stay the same for an object at any location Mass measures an objects amount of matter Measured in grams (g) or kilograms (kg) Weight changes due to gravity’s force and distance of celestial body Planets, stars, etc. Measured in Newtons and pounds

22
Review Objectives Describe the three properties of all matter. All matter has mass, volume Identify the units used to measure volume and mass. The unit for Volume = milliliter (ml) or cubic centimeter (cm 3 ) The unit for Mass = kilogram (kg), gram (g), and milligram (mg) Distinguish between mass and weight. Mass is the amount of matter in an object. Weight is the gravitational force on an object.

23
Annotated reading assignment w/questions Students work in partners, one reads while the other annotates: Circle or underline words you do not understand. Write any questions in the margins After reading one paragraph students stop, discuss and summarize, especially if there are words or phrases circled/questions in margins For each paragraph switch jobs. After all of reading and discussion is complete begin questions. Take turns recording answers in space provided. Highlight the answer in the text and notate on the answer paragraph # and sentence # where found.
