Third Grade Science Overview

The Third 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 to 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 Third Grade consists of three basic units:

Ideas and Inventions:  This module consists of four sequential investigations that promote student creativity and inventiveness.  Each investigation provides valuable science content while introducing a conventional technique for revealing the unseen.                      

Physics of Sound:  This module consists of four sequential investigations, each designed to expose a specific set of concepts.  Students learn to discriminate between sounds generated by dropped objects, how sounds can be made louder or softer and higher or lower, how sounds travel through a variety of materials, and how sounds get from a source to a receiver.  The investigations provide opportunities for students to explore the natural and humanmade worlds by observing and manipulating materials in focused settings using simple tools.                                       

Water:  Water is the most important substance on Earth.  Water dominates the surface of our planet, changes the face of the land, and defines life.  These powerful, pervasive ideas are introduced here.  The Water Module consists of four investigations in which students explore properties of water, changes in water, interactions between water and other earth materials, and how humans use water.

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:
