10.53.805 SCIENCE CONTENT STANDARDS FOR SECOND GRADE
(1) Physical science content standards for second grade are that each student will:
(a) plan and conduct an investigation to describe and classify various materials by their observable properties;
(b) conduct an investigation and analyze data to determine which materials have the properties best suited for an intended purpose;
(c) make observations to construct an evidence-based claim of how an object made of a small set of pieces can be disassembled and made into a new object; and
(d) construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
(2) Life science content standards for second grade are that each student will:
(a) plan and conduct a cause and effect investigation to determine whether plants need sunlight and water to grow;
(b) develop a simple model that mimics the structure and function of an animal in dispersing seeds or pollinating plants; and
(c) make observations of plants and animals to compare and contrast the diversity of life in different habitats.
(3) Earth and space science content standards for second grade are that each student will:
(a) use information from several sources to provide evidence that earth events can occur quickly or slowly;
(b) construct explanations to compare multiple physical and naturally built designs which impact wind's or water's effect on the shape of the land;
(c) develop models to represent the shapes and kinds of land and bodies of water in an area; and
(d) obtain information to identify where water is found on earth and that water can be solid, liquid, or gas.
