What are Science Lesson Plans?

A science thematic unit is a framework for teaching everything a young child needs to know, all centered around a central theme.
Thematic units and unit studies include elements of math, reading, social studies, science, language arts, and STEM. Most thematic units are used at the preschool and kindergarten level, although you can also study using some elements of unit studies in older grades.
Many homeschooling families use the concept of thematic units to teach STEM well into middle school.
Use the following STEM thematic units for preschool and thematic units for kindergarten in your classroom or homeschool and find everything you need to explore theme units in your classroom.
