2Tuesday Oct 23 or Wednesday Oct 24 Do Now 1. Write the atomic mass of Helium as a whole number. 2. Helium has ____ protons. 3. Helium has ____ neutrons.DateTable of ContentsPageOrVolumeWhatever page you’re on
3Today’s Plan Take notes on volume Practice finding volume of liquids and rectangular objectsGraduated Cylinder RaceVolume exit slipBe able to apply the definition of volumeBe able to read a graduated cylinderBe able to find the volume of a rectangular objectBe able to find the volume of an irregular object
4What do you already know about volume? What is it?What units do you measure it in?What are some tools you can use to measure volume?Why is volume important?
5Why is volume important? You need to be able to find volume for your labs. If you cannot measure volume accurately your experiment results will be wrong.
6Quick Review Matter is anything that has mass and takes up space. Matter is made of atoms.Atoms are made of subatomic particles.
7Quick ReviewThe 3 subatomic particles are protons, neutrons, and electrons.Protons = positiveNeutrons = neutral (no charge)Electrons = negativeThe number of protons in the nucleus (center of the atom) is what makes each thing in our world different.
8Volume Notes Volume is the amount of space an object takes up. All matter takes up space. Even gases have volume.
9Quick CheckWhat is volume?Does all matter have volume?
10Volume Notes Volume is measured in these units: Liters (L) Milliliters (mL)Cubic centimeters (cm3)1mL = 1cm3
11Quick CheckWhat are the units you can use to measure volume?
12Fill in the blank with “small” or “large” An elephant has a ___________ amount of volume.A bug has a __________ amount of volume.
13If someone said that a house was really big, does that mean it has a large or small amount of volume? How can you tell?If someone said that a ring was really small, what does that tell you about the volume? How can you tell?
14Volume NotesThe formula to find the volume of a rectangular object is length x width x height.V = l x w x h
15Volume Notes What is the volume of the rectangular object? V = l x w x hLength = 5cmWidth = 2cmHeight = 8cm5 x 2 x 8 = 80cm38cm2cm5cm
16What is the volume of the ice cube? V = l x w x hLength = 3cmWidth = 3cmHeight = 3cm3 x 3 x 3 = 27cm3If an ice cube has a length of 3cm, a width of 3cm, and a height of 3cm, what is the volume?
17What is the volume of the box What is the volume of the box? V = l x w x h Length = 100cm Width = 50cm Height = 50cm 100 x 50 x 50 = 25,000cm3Find the volume of the cardboard box below.50cm100cm50cm
18Measuring VolumeWe will be using graduated cylinders to find the volume of liquids and other objects.Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye-level with the level of the water.What is the volume of water in the cylinder? _____mLWhat causes the meniscus?A concave meniscus occurs when the molecules of the liquid attract those of the container. The glass attracts the water on the sides.Top Image: Bottom Image:
19Volume NotesUse a graduated cylinder to find the volume of a liquid.
20Volume Notes Use these steps to read a graduated cylinder: Put the GC on a flat, level surfaceBe at eye level with the surface of the liquidRead the mark closest to the bottom of the meniscus (curved part of the water).
21Volume Notes Counting by 1s When reading a GC, first identify what the cylinder is counting by.It might count by 1, 2, 5, 0.1, 0.2, 0.5, or othersCounting by 1s
226.6mL Counting by 0.2s 7.6mL 7mL What is it counting by? What is the volume of the liquid?6.6mLCounting by 0.2s7.6mL7mL
23What is it counting by? 21mL 21.5mL 20.5mL 20mL The short lines in between represent half of a milliliter. So it is counting by 0.5s21mL20.5mL21.5mL20mL
25What is the volume of water in each cylinder? 37mL52mL23mLImages created atABC
26Volume NotesMeasure the volume of an irregularly shaped object by using water displacement.Find the amount of water with the object and the amount of water without the object. Subtract those numbers to find the volume.
27Amount of water with object: _____ Amount of water without object: ______5.6mL – 4.8mL = 0.8mL
28Find the volume of the objects Metal tube: = 10cm3Ring: 68 – 64 = 4cm3
29Add the word volume and the page number to your glossary.
30Graduated Cylinder Race What’s best for accurately filling a graduated cylinder?
31Graduated Cylinder Race In your lab book write:Graduated Cylinder RaceIV:DV:Hypothesis:
32Graduated Cylinder Race What is my independent variable?What is my dependent variable?How can we measure that?
33Graduated Cylinder Race Write a good hypothesis for your experiment.
34GC Race Procedure: 1. gather supplies: 1 pipette, 1 sponge, 1 beaker of water, 1 graduated cylinder2. Test how long it takes to fill a graduated cylinder to exactly 9mL with a sponge. Record.3. Test how long it takes to fill a graduated cylinder to exactly 9mL with a pipette. Record.4. analyze your data in a table and graph it in a bar graph.5. Write a conclusion about your results.
35Decide what number you are at your table. Create the table below in your lab book:SpongePipetteTable 1 timeTable 2 timeTable 3 timeTable 4 timeTable 5 timeTable 6 timeTable 7 timeTable 8 timeTable 9 timeAverage:
36Student 1 get supplies 1 pipette 1 sponge 1 beaker of water 1 graduated cylinder
37Student 2 will be using the sponge to add water in the first trial. Student 4 will check to make sure the measurements are EXACT and make sure everyone is following safety rules.Student 1 will raise his or her hand when the group is ready for the teacher to check and get the time.EVERYONE: record your time.
38Student 1 prepare the materials for the next trial. Put water beaker again.Wring out sponge.Order materials neatly.
39Student 3 will add the water to the graduated cylinder with the pipette. Student 1 will check to make sure measurements are EXACT and make sure everyone is being safe.Student 4 will raise his or her hand for the teacher to check and get the time.EVERYONE record your time.
40Student 2 put away supplies carefully Student 3 dry table
42Graph your resultsRemember to have a title, x-axis label, y-axis label, and accurate intervals.Make a BAR GRAPH.Graph only the averages.
43Needs to be at least 5 sentences! Write a conclusionRemember to haveA statement saying whether your hypothesis was right or wrong3 supporting details (from your table or graph)a sentence summing up the resultsNeeds to be at least 5 sentences!
44Exit SlipLabel your note card with your FIRST AND LAST NAME, DATE, and HOUR. Labeling this correctly is worth one point.
45Exit SlipClear everything off of your table. Close lab books and put them on the floor.NO TALKING, at all. If you have a question raise your hand SILENTLY and wait for the teacher.For multiple choice you can just write the letter of your answer. When you are measuring you need to write the number and the units.
46Exit Slip1. A student describes an object as being “very large.” This means the object has a) A high mass b) A high volume c) A low mass d) A low volume
47Exit Slip2. What is the volume of the rectangular object? Remember to write your units.3cm2cm4cm
48Exit Slip3. What is the volume of the liquid in the graduated cylinder? Remember to include your units.
49Exit Slip4. What is the volume of the object in the graduated cylinder? Be careful about the units!!

57Today’s Plan Create our goals for this class Read about the states of matterTake notes on the states of matterShort video clip on the states of matterStates of matter exit slipBe able to describe the particle location and movement in a solid, liquid, and gas
59Today we will be defining our individual goals so you can see why it is important to YOU to be successful in this class.
60Complete your goal sheet one part at a time. Do not move ahead Complete your goal sheet one part at a time. Do not move ahead. These will be hung around the room, so make sure they are very neat.
61Fill in your name neatly. Think about your goal. DON’T WRITE IT YET. Here are some goal options:My goal is to become a nurse.My goal is to be a pro football player.My goal is to have a lot of options when I graduate high school.My goal is to have my own business.My goal is to have a large family.Once you have your goal and how you want to phrase it, write it neatly on your sheet.
62Explain why your goal is important to you. Examples: My goal is important to me because I’m not sure exactly what I will want in the future, so I want to make sure I am able to do anything when the time comes.My goal is important to me because I have always wanted to be a nurse so I can help people.My goal is important to me because I love football and want to get paid for playing it.
63Write at least 3 steps you’ll need to take to reach your goal. Think about what steps you’ll need to take to reach your goal.Example:I need to try hard and keep focused on my goal.I need to pass all of my classes in middle and high school.I need to do volunteer work to develop and practice my skills.I need to get into a good college and pass those classes.I need to surround myself with people who help me achieve my goal instead of keep me from reaching it.Write at least 3 steps you’ll need to take to reach your goal.
64Think about how this class helps you reach your goal. Example: Being successful in 7th grade science helps me reach my goal because it gets me ready for all the science classes I’ll need to pass in the future.Being successful in 7th grade science helps me reach my goal by improving my problem solving skills so I am better prepared for challenges.
65Think about how you, personally, will know that you have been successful in this class. What percent would you need to get to prove that you were successful and are ready to take the next step to reach your goal?Hints:Don’t choose 100% because even someone who knows a LOT about science can make a mistake or disagree with the answer to a question.Don’t choose anything under 60% because everyone in here is capable of getting a percent higher than that.
67Make a KWL Chart in your lab book KnowWant to knowLearnedFill in what you already Know about the states of matter. Then fill in what you Want to know about the states of matter.
68States of Matter Reading Read with your group.Write 1 or 2 sentences about the most important things to remember from each paragraph.After you’ve read, you should have between 7 and 14 sentences written in your lab book.
69Matter NotesThe 3 states of matter are solid, liquid, and gas.
70Solids: Definite shape Definite volume They keep their shape and volume no matter where you put them.
71The cherries and the bagel kept their shapes in the container The cherries and the bagel kept their shapes in the container. They would be the same size whether or not they were in the container. This makes them solids.
72The particles in a solid are closely packed in a fixed position (which is why solids have definite shape and volume).The particles in a solid vibrate but don’t move from place to place.
73Liquids: Definite volume No shape of its own Spread into a puddle if they don’t have a container
74These are liquids because they take up space, but they don’t have their own shape. Notice how they fill out in the container or spread if they don’t have a container.
75The particles in a liquid are tightly packed, but they move around more than they do in a solid (which is why liquids don’t have their own shape).The particles in a liquid vibrate, move around, and slide past each other.
76Gases: No definite shape No definite volume This means the shape and size can change.
77The hot air takes on the shape of the balloon The hot air takes on the shape of the balloon. It can squeeze together to fill the balloon or it can spread out in the air outside of the balloon. Since it has no shape of its own and the size can change, hot air is a gas.
78Gas particles can spread out or squeeze together to fill a container. The gas particles vibrate and move freely at high speeds.
79How can you tell which is a solid, liquid, and a gas?
81Make a KWL Chart in your lab book KnowWant to knowLearnedFill out the last column of the chart with what you Learned about the states of matter.
82Add the words to your glossary with their page numbers. Tape paper in lab bookAdd the words to your glossary with their page numbers.states of matterSolidLiquidgas
83Exit SlipLabel your note card with your FIRST AND LAST NAME, DATE, and HOUR. Labeling this correctly is worth one point.
84Exit SlipClear everything off of your table. Close lab books and put them on the floor.NO TALKING, at all. If you have a question raise your hand SILENTLY and wait for the teacher.For multiple choice you can just write the letter of your answer.

86Exit Slip2. If you looked through a very powerful microscope, what would you see atoms doing in a gas?a) Bouncing and moving around freelyb) Moving around a little bit and sliding over each otherc) Packed tightly together with little movementd) None of the above
87Exit Slip3. Mrs. Thorsen asks you to reach inside a bag and take out an object. It feels hard and does not move under your touch. What could you say this object is for sure? a) A rubber ball b) A liquid c) Made of leather d) A solid
88Exit Slip4. Do the blue particles show you a solid, liquid, or a gas and how can you tell?
