2: Earth and Space

2.2: Understand and apply knowledge of processes and changes on or in the earth?s land, oceans, and atmosphere.

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.

Rock Cycle

2.4: Understand and apply knowledge of weather and weather patterns.

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: Understand and apply knowledge of the properties, movements, and locations of objects in our solar system.

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.

Seasons: Earth, Moon, and Sun

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: Physical Science

3.1: Understand and apply knowledge of how to describe and identify substances based on characteristic properties.

3.1.3: The properties of a substance can be measured using tools and technology.

Weight and Mass

3.2: Understand and apply knowledge of states of matter and changes in states of matter.

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.

Phases of Water

3.4: Understand and apply knowledge of sound, light, electricity, magnetism, and heat.

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.

Color Absorption
Heat Absorption

3.4.3: Electricity in circuits can produce light, heat, sound, and magnetic effects. Electricity can only flow through a closed circuit.

Circuit Builder
Energy Conversions

3.4.4: Magnets attract and repel each other and certain kinds of other materials.

Magnetism

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.

Conduction and Convection
Heat Transfer by Conduction

3.5: Understand and apply knowledge of how forces are related to an object?s motion.

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.

Measuring Motion

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: Life Science

4.1a: Structures, characteristics, and adaptations of organisms that allow them to function and survive within their habitats.

Flower Pollination

4.1b: How individual organisms are influenced by internal and external factors.

Homeostasis

4.1c: The relationships among living and non-living factors in terrestrial and aquatic ecosystems.

4.1c.1: Animals depend on plants. Some animals eat plants for food. Other animals eat animals that eat the plants.

Forest Ecosystem
Prairie Ecosystem

4.2: Understand and apply knowledge of environmental stewardship.

4.2.2: Humans change environments in ways that can be either beneficial or detrimental to themselves or other organisms.

Pond Ecosystem

4.3: Understand and apply knowledge of basic human body systems and how they work together.

4.3.1: The human organism has systems which interact with one another. These systems include circulatory, respiratory, digestive, musculoskeletal, etc.
