4.P.1.1 (Forces and Motion) Explain how magnets interact with all things made of iron and with other magnets to produce motion without touching them.

4.P.1.2 (Forces and Motion) Explain how electrically charged objects push or pull on other electrically charged objects and produce motion.

4.P.2.2 (Properties and Change) Explain how minerals are identified using tests for the physical properties of hardness, color, luster, cleavage and streak.

4.P.2.3 (Properties and Change) Classify rocks as metamorphic, sedimentary or igneous based on their composition, how they are formed and the processes that create them.

4.P.3.1 (Conservation and Transfer) Recognize the basic forms of energy (light, sound, heat, electrical, and magnetic) as the ability to cause motion or create change.

4.P.3.2 (Conservation and Transfer) Recognize that light travels in a straight line until it strikes an object or travels from one medium to another, and that light can be reflected, refracted, and absorbed.

4.E.1.1 (Earth in the Universe) Explain the cause of day and night based on the rotation of Earth on its axis.

4.E.2.2 (Earth History) Infer ideas about Earth’s early environments from fossils of plants and animals that lived long ago.

4.E.2.3 (Earth History) Give examples of how the surface of the earth changes due to slow processes such as erosion and weathering, and rapid processes such as landslides, volcanic eruptions, and earthquakes.
