Minnesota Standards for Fourth Grade Science

MN.4.2. Physical Science

4.2.1. Matter The student will understand that objects have observable properties that can be measured. Measure temperature, volume, weight and length using appropriate tools and units. The student will understand that solids, liquids and gases are states of matter that have unique properties. Distinguish between solids, liquids and gases in terms of shape and volume. Describe how the states of matter change as a result of heating and cooling.

4.2.3. Energy The student will understand that energy appears in different forms, including heat and electromagnetism. Describe the transfer of heat energy when a warm and a cool object are touching or placed near each other. Compare materials that are conductors and insulators of heat and/or electricity. The student will understand that energy can be transformed within a system or transferred to other systems or the environment. Construct a simple electrical circuit using wires, batteries and light bulbs. Demonstrate how an electric current can produce a magnetic force.

MN.4.3. Earth and Space Science

4.3.1. Earth Structure and Processes The student will understand that rocks are Earth materials that may vary in composition. Recognize that rocks may be uniform or made of mixtures of different minerals. Describe and classify minerals based on their physical properties.

4.3.2. Interdependence Within the Earth System The student will understand that water circulates through the Earth's crust, oceans and atmosphere in what is known as the water cycle. Identify where water collects on Earth, including atmosphere, ground and surface water, and describe how water moves through the Earth system using the processes of evaporation, condensation and precipitation.

MN.4.4. Life Science

4.4.4. Human Interactions with Living Systems The student will understand that microorganisms can get inside one's body and they may keep it from working properly. Recognize that the body has defense systems against germs, including tears, saliva, skin and blood.
