= LESSON PLAN = Created by:Vineyard First Grade

__Core Objective/Standard__:
Physical Science; Analyze objects and record their properties

__Student learning objective__:
Students will predict, identify, and describe changes in matter when heated, cooled, or mixed with water.

__Materials needed__: Heating element (hot plate), food coloring, ice cube tray, water, ice cubes, paper plates, tea kettle, hot pads, a metal cake pan, and assessment worksheet.

__Teacher (To) directions/actions/instructions__:
Heat a hot plate. Fill the tea kettle with water. Place the kettle on hot plate. Have students predict what will happen and write or draw on assessment worksheet. When the water boils and steam rises, place a cake pan filled with a few ice cubes over the steam. Use the hot pads to hold the cake pan. Show students how the steam (gas) melts the ice cubes and explain the process of solids, liquids, and gases.

__Teachers/Students (With) actions__:
Place students in small groups. Give the groups a small pitcher of water, food coloring, and an ice cube tray. Help students place a few drops of food coloring in the pitcher of water, fill the ice cube tray and place it in the freezer over night.

__Students (By) actions/activities students will do during lesson__:
Give students a paper plate and the ice cubes that they made the day before. Have students place their ice cube on the plate and place it in the sun. Trace around water puddle each day to observe over time how the ice cube melts and the water evaporates.

__Assessment-these may be written, verbal, observations, etc__:
Collect worksheet to see if students made reasonable predictions and described actual results of experiments.
