In second grade, students will build upon their understanding of the basic needs of plants and animals developed in Kindergarten and First Grade. They will explore materials science and investigate and classify different kinds of materials by their observable properties, including color, texture, and heat conduction. They will explore computer science combining mathematics and computers and investigate numerical relationships while learning about the sequence and structure required in computer programs. Students will learn that in nature, some changes happen slowly and others happen quickly. They will learn about the water cycle and water’s effect on the Earth’s surface.
