Second Grade Science Overview

The Second Grade Science program consists of hands-on experiences in which students are taught to investigate and explore.  The inquiry-based, hands-on science curriculum is designed to provide children with exciting science experiences that extend their fascination with the world and help them learn the science skills and concepts they will need later in school and in life.

The Science Curriculum for Second Grade consists of two basic units:

Air and Weather:  This unit consists of four sequential investigations, each designed to introduce concepts in earth science.  The investigations provide opportunities for students to explore the natural world by using simple tools to observe and monitor change.

Solids and Liquids:  This unit provides experiences that heighten students' awareness of the physical world.  Matter with which we interact exists in three fundamental states:  solid, liquid, and gas.  In this module students have introductory experiences with two of the states of matter, solid and liquid

Through exploration of the units above and various activities integrated with reading and math, students will continue their study in the following Iowa Core Science Standards.

Science as Inquiry

  • Ask questions about objects, organisms, and events in the environment.
