2.2.1: The surface of the earth changes. Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes such as landslides, volcanic eruptions, floods and earthquakes.
2.4.1: Weather is always changing and can be described by measurable quantities such as temperature, wind direction and speed and precipitation.
2.5.1: Most objects in the solar system are in regular and predictable motion. The rotation of the earth on its axis every 24 hours produces the day-and-night cycle. To people on the earth this turning of the planet makes it seem as though the sun, planets, and stars are orbiting the earth once a day.
2.5.2: The sun appears to move across the sky in the same way every day. Its apparent path changes slowly across the seasons.
2.5.3: The moon?s orbit around the earth once in about 28 days changes what part of the moon is lighted by the sun and how much of that part can be seen from the earth ? the phases of the moon.
2.5.4: Eight planets and many other objects revolve around our Sun in predictable patterns. These planets and objects are composed of varied materials.
3.1.3: The properties of a substance can be measured using tools and technology.
3.2.1: Materials can exist in different states ? solid, liquid and gas. Some common materials can be changed from one state to another by heating or cooling.
3.4.1: Sound is produced when vibrations from objects travel through a medium and are received. Sound can vary in volume. The pitch of a sound can be varied by changing the rate of vibration.
3.4.2: Light travels in a straight line until it strikes an object. Light can be reflected by a mirror, refracted by a lens, or absorbed by an object.
3.4.3: Electricity in circuits can produce light, heat, sound, and magnetic effects. Electricity can only flow through a closed circuit.
3.4.4: Magnets attract and repel each other and certain kinds of other materials.
3.4.5: Heat can be produced in many ways, such as burning, rubbing, or mixing one substance with another. Heat can move from one object to another by conduction.
3.5.1: The motion of an object can be described by its position, direction of motion, and speed. That motion can be measured and represented on a graph.
3.5.2: Changes in speed or direction of motion are caused by forces. The greater the force, the greater the change in motion. The more massive an object, the less effect a given force will have in changing its motion.
4.1c.1: Animals depend on plants. Some animals eat plants for food. Other animals eat animals that eat the plants.
4.2.2: Humans change environments in ways that can be either beneficial or detrimental to themselves or other organisms.
4.3.1: The human organism has systems which interact with one another. These systems include circulatory, respiratory, digestive, musculoskeletal, etc.
