This Science-Introduction to the Unit on Matter lesson plan also includes:
First graders gain knowledge about solids, liquids and gases by taking a look at the things around them. They have to classify certain picture cards based on which category they feel the picture falls under. As a whole, the class completes a KWL chart for solids, liquids, and gases. By giving a pretest the teacher knows where he or she may have to start the lesson and thus build upon after that.
