The lesson plan is about colors. The children will listen to the story "Little Blue and Little Yellow" and then do a activity where they mix primary colors using pipettes to make secondary colors. The goals are for children to identify an event from the story, use a pipette, and mix two or more colors. During the activity, the teacher will demonstrate using a pipette and then allow children to explore mixing their own colors. Children will be assessed through observation and discussion during the activity.
