They sort and classify objects according to their properties and explain their classification systems. The module introduces the students to simple tools of science, such as rulers, magnifiers and balances. In this earth science module, students investigate rocks, soils and water and the interactions among them. The students observe the earth materials around them and compare different types of soil and rocks in terms of color, texture and reactions with water. The module includes an introduction to fossils and their formation.
Students explore the characteristics of guppies, snails and aquatic plants in classroom aquaria.
By observing those organisms in their environment, the students learn about what organisms need to survive. They recognize that the structures of the organisms serve specific functions that enable them to survive in their environments. Then, they investigate the characteristics and behaviors of gerbils and isopods. They recognize that an animal's behavior and structures enable it to meet its needs and that animals can survive only in environments in which they can meet their needs. Students investigate the materials from which objects are made.
