Important Dates….. Your next quiz will be on: Friday, October 3 rd (A day) Monday, October 6 th (B day) The quiz will be on 6.P.2.1 Matter

6.P.2.2 On the next blank page in your notebook, write this title: 6.P.2.2 States of Matter add entry to table of contents

6.P.2.2 States of Matter In this unit our objective is to: – Explain the effect of heat on the motion of atoms through a description of what happens to particles during a change in phase – Where is this objective in our room?

3 States of Matter Most substances can exist as a Solid Liquid gas Let’s think about water!

Water as an Example…. As a Solid = ice (North and South Poles), snow As a Liquid = in oceans, lakes, streams, rivers As a gas = water vapor in atmosphere, tea pot

Today’s Lab We are trying to figure out what happens to the atoms that make up matter when it changes state… To investigate this, we will be investigating water in all 3 stats of matter We will also be investigating how a thermometer works

You will be working in groups… Go to the page in your notebook labeled 6.P.2.2 States of Matter, Write Thermometer Lab Look closely at your thermometer. The liquid inside is probably a type of alcohol that’s been dyed red.

You will be working in groups… Look closely at your thermometer. The thermometer has numbers on it. This is the range of temperatures that the thermometer will measure. Everyone record the range of temperatures now in your notebook (lowest temp. to highest temp.) -20 °C to 110 °C

Today’s Lab Practice reading the temperature in °C by having your eye at the same level as the top of the red liquid. What is the temperature? Each line = 1 °C Everyone record the temperature now in your notebook This is the temperature in our room The liquid is probably between 20 °– 30 °C

Today’s Lab Put your thumb or finger on the red bulb and see if the red liquid moves in the thin tube. Does the red liquid move? Why do you think it moved? It moved up because you are warmer than our classroom temperature

Today’s Lab You will now receive a handout Your group will determine the temperatures of ice, cold water and room temperature water You will write the temperature on your handout You will also draw a picture of each state For safety reasons I will stand near the boiling hot water and call your group back one group at a time

Today’s Lab Now put the thermometer in room temperature water. Keep it in the cold water until the liquid stops moving. Record the temperature in °C. You will do this for ice cold water too

Today’s Lab I will help you place the thermometer in hot water and you will watch the red liquid. Keep it in the hot water until the liquid stops moving. Record the temperature in °C.

Today’s Lab Does anyone have any questions You may start now

Brain Pop Video Video on “States of Matter” Video You are listening for how the atoms move in a solid, liquid, and a gas Add this to your handout when you hear the answers in the video

States of Matter Now turn your handout over You will see 3 equal sections Label section 1 : Solids Label section 2: Liquids Label section 3: Gases You will copy the following information down now

Solids Fact #1: Has a definite volume and shape Fact #2: Atoms are packed close together. Fact #3: Atoms vibrate a little Add heat solid can become a liquid!!! Check it out!!!!!

Liquids Fact #1: Has a definite volume, but not a definite shape Fact #2: Particles touch, but bounce around Fact #3: Take the shape of their container. Add heat liquid can become a gas!!! Check this out now!!!!

Gases Fact #1: Has no definite volume or definite shape Fact #2: If not contained, gases will spread out to fill the space Fact #3: If contained, they Will take the shape of their container. ComparingAll Three!!!

Draw the Atoms! Watch the atoms on the screen Now draw the atoms in a solid, liquid, and gas at the bottom of your handout

Handout Fold your handout in half I will come around an staple it into your notebook now

Back to our thermometer lab… Based on what you know about the way molecules move in hot liquids, explain why the liquid in the thermometer goes up when heated? When heated, the molecules of the red liquid inside the thermometer move faster. This causes the molecules to spread a little further apart. They have nowhere to go other than up the tube.

Back to our thermometer lab… Based on what you know about the way molecules move in colder liquids, explain why the red liquid in the thermometer goes down when place in ice, cold water? When the thermometer is placed in ice, cold water, the molecules slow down and their attractions bring them a little closer together bringing them down the tube.

Back to our thermometer lab… Why do you think the tube which contains the red liquid is so thin? The red liquid is contained in a very thin tube so that a small difference in the movement of the atoms within the liquid will be noticeable.

Back to our thermometer lab… Why does the thermometer have a larger outer tube? The large outer tube has two purposes—to protect the fragile inner tube and act as a magnifier to help you better see the red liquid.
