Section 389.244 - Second grade: Science

By the beginning of the second grade, pupils must know and be able to do everything required in the previous grades for science offered in public schools. Instruction in the second grade in science must be designed so that pupils meet the following performance standards by the completion of the second grade:

1. For the area of physical science, understand matter and its interactions, as demonstrated by the ability of the pupil to:

(a) Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.

(b) Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.

(c) Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and made into a new object.

(d) Construct an argument with evidence that some changes caused by heating or cooling are able to be reversed and some are not.

2. For the area of life science, understand:

(a) The interactions, energy and dynamics of ecosystems, as demonstrated by the ability of the pupil to:

(1) Plan and conduct an investigation to determine if plants need sunlight and water to grow.

(2) Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.

(b) The unity and diversity of biological evolution, as demonstrated by the ability of the pupil to make observations of plants and animals to compare the diversity of life in different habitats.

3. For the area of earth science, understand:

(a) The earth's place in the universe, as demonstrated by the ability of the pupil to use information from several sources to provide evidence that events affecting the earth can occur quickly or slowly.

(b) The earth's systems, as demonstrated by the ability of the pupil to:

(1) Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.

(2) Develop a model to illustrate the shapes and kinds of land and bodies of water in an area.

(3) Obtain information to demonstrate where water is found on earth and that water can be solid or liquid.

4. For the area of engineering technology, understand design, as demonstrated by the ability of the pupil to:

(a) Ask questions, make observations and gather information about a situation which persons desire to change to define a simple problem that can be solved through the development of new or improved objects or tools.

(b) Develop a simple sketch, drawing or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.

(c) Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of the performance of each object.
