AGENDA Hook Anticipatory Set Instruction Guided Practice Name

AGENDA • • • Hook (Anticipatory Set) Instruction Guided Practice (Name that process) Evaluation (Assessment) Closure

STANDARD • 3 -4. 2 Explain how water and other substances change from one state to another (including melting, freezing, condensing, boiling, and evaporating).

OBJECTIVE • The students will be able to explain how water and other substances change from one state to another (including melting, freezing, condensing, boiling, and evaporating).

Matter is anything that takes up space and has mass.

STATES OF MATTER • The Three States of Matter Solids Liquids Gas

STATES OF MATTER SOLIDS • Solids have a definite size and shape. The size and shape do not change. • Particles of solids are tightly packed. • EX- tables, chairs, cups, plates, pencils, erasers

STATES OF MATTER LIQUIDS • Liquids have a definite volume, but they take the shape and size of their containers. § Particles of liquids are tightly packed, but are far enough apart to slide over one another. § EX. water, juice, milk, soda

STATES OF MATTER GAS • Gases do not have a definite shape or volume. They take the shape and size of their container. • Particles of gases are very far apart and move freely. • EX. Air (oxygen), Helium

Mass • Mass is how much matter is in an object. • Mass can be measured using a balance. • An object with a large mass feels heavy.

Volume This is not the volume that we talked about in sound! Volume is the amount of space an object takes up. • Volume of a solid with rectangular shape can be measured with a ruler. • Volume of a liquid can be measured with a beaker or graduated cylinder. • Volume of a gas can be measured with a graduate syringe. • An object that takes up more space has a greater volume.

PHASE CHANGES Description of Phase Change Solid to liquid Term for Phase Change Melting Liquid to Freezing solid Heat Movement During Phase Change Heat goes into the solid as it melts. (Heat is added) Heat leaves the liquid as it freezes. (Heat is removed)

PHASE CHANGES Description of Phase Change Term for Phase Change Heat Movement During Phase Change Liquid to gas Evaporation Heat is added. Gas to liquid Condensation Heat is removed. Gas is cooled and changes to a liquid on the cool surface of the object.

Boiling occurs when a lot of heat is being added from a source. When boiling liquid changes to gas and bubbles begin to form in the liquid at a given temperature.

NAME THAT PROCESS! • I left a popsicle outside on a hot sunny day. When I returned, it was just a pool of popsicle juice. What happened? • Landon’s mom told him to be sure that he watched the pot on the stove. He forgot and the gravy was overflowing over the sides. What was happening?

• Ja. Niya just stepped out of the shower and the mirror in the bathroom is very foggy. She noticed that water vapors are appearing on the mirror. What process is occurring? • Cameron wanted some ice cubes, so she placed water in the freezer. What process will occur? • One hot sunny, Ma. Caju left her water in a cup outside. When she returned to get the cup, there was no water in it! What happened to the water?
