This paper towel
Write in your notes in a colored marker Kinetic energy energy possessed by an object in motion
Is the speed of molecules different in hot and cool water? HOT COLD
Write in your notes in a colored marker Kinetic energy energy possessed by an object in motion heating an object molecular motion cooling an object molecular motion
Write in your notes in a colored marker Kinetic energy energy possessed by an object in motion heating an object INCREASES molecular motion cooling an object DECREASES molecular motion
In a thought bubble write: Heating and cooling a liquid Describe what happens to the motion of particles as heat increases
Make the three flips for s/l/g To go over the catalyst
What do you see? Let s come up with some definitions.
Fill out your worksheet: This paper towel What happened to it? Where did the water go?!?!

Phase A form of matter (solid, liquid, gas)
Kinetic energy Energy possessed by an object in motion
(Phase change) Deposition - Gas to solid At night, it can get so cold that the water vapor in the air turns straight to ice
(Phase change) Condensation - Gas to liquid When water vapor molecules in the air get cold, they can turn into water
(Phase change) Boiling - Liquid to gas When liquid gold is heated enough it will become gaseous gold
(Phase change) Melting - Solid to liquid When iron is heated past its melting point, it become liquid iron
(Phase change) Evaporation - Liquid to gas When water is left out long enough, individual molecules break free and go into the air
(Phase change) Sublimation - Solid to gas When a solid is exposed to temperatures much higher that its boiling point, it becomes gas
(Phase change) Freezing - Liquid to solid When oil is cooled lower than its freezing point, it solidifies
Activity 1: Melting ice cube 1. What phase change occurred? 2. Where did the energy come from to melt the ice? 3. What do you think happened to the speed of the molecules when the ice was heated?
Activity 1: Melting ice cube
Activity 1: Melting ice cube Draw pictures that illustrate what happens to the motion of molecules as ice melts
Activity 2: Outside of the cup 1. What do you observe outside of the cup? 2. Draw a picture of what you see. 3. Where did that water come from?
Activity 2: Outside of the cup
Activity 2: Outside of the cup 1. What do you observe outside of the cup? 2. Draw a picture of what you see. 3. Where did that water come from? 4. What happened to the water molecules in the video?
Activity 2: Outside of the cup
Activity 2: Outside of the cup 1. What do you observe outside of the cup? 2. Draw a picture of what you see. 3. Where did that water come from? 4. What happened to the water molecules in the video? 5. Why did the cup in the bag have less condensation? When your group is ready, start working on the worksheet. Once every group member can answer the questions in the worksheet, you will get the materials for the next. You may not write on the worksheet.
Activity 3: Melting ice vs melting dry ice 1. Do regular ice and dry ice melt in the same way? 2. What is the phase change that occurs in the normal ice? 3. What is the phase change that occurs in the dry ice? 4. What is dry ice made out of? No processing task today (we re going to do it tomorrow)
Draw a comic of how water molecules in air condense on the outside of a cup.. Assignment #1 (New Unit: States of Matter) States of Matter LEVEL ZERO VOICE PROCESSING TASK (10 minutes, individual work): Use at least three different colors State Solid Liquid Gas How fast do molecules move? Kinetic energy Does shape change if container changes? Picture of molecules Picture of real life example
