1: Properties and Principles of Matter and Energy

1.1: Changes in properties and states of matter provide evidence of the atomic theory of matter

1.1.A: Objects, and the materials they are made of, have properties that can be used to describe and classify them

1.1.A.a: Describe and compare the masses (the amount of matter in an object) of objects to the nearest gram using balances

Weight and Mass

1.1.A.c: Identify situations where no two objects can occupy the same space at the same time (e.g. water level rises when an object or substance such as a rock is placed in a quantity of water)

Measuring Volume

1.2: Energy has a source, can be stored, and can be transferred but is conserved within a system

1.2.A: Forms of energy have a source, a means of transfer (work and heat), and a receiver

1.2.A.a: Construct and diagram a complete electric circuit by using a source (e.g., battery), means of transfer (e.g., wires), and receiver (e.g., resistance bulbs, motors, fans)

Circuit Builder

1.2.A.c: Classify materials as conductors or insulators of electricity when placed within a circuit (e.g., wood, pencil lead, plastic, glass, aluminum foil, lemon juice, air, water)

2: Properties and Principles of Force and Motion

2.1: The motion of an object is described by its change in position relative to another object or point

2.1.A: The motion of an object is described as a change in position, direction, and speed relative to another object (frame of reference)

2.1.A.b: Describe an object's motion in terms of distance and time

Free Fall Tower

2.2: Forces affect motion

2.2.A: Forces are classified as either contact (pushes, pulls, friction, buoyancy) or noncontact forces (gravity, magnetism), that can be described in terms of direction and magnitude

2.2.A.c: Observe and identify friction as a force that slows down or stops a moving object that is touching another object or surface

Free Fall Tower

2.2.B: Every object exerts a gravitational force on every other object

2.2.B.a: Determine the gravitational pull of the Earth on an object (weight) using a spring scale

Weight and Mass

2.2.D: Newton's Laws of Motion explain the interaction of mass and forces, and are used to predict changes in motion

2.2.D.d: Predict the effects of an electrostatic force (static electricity) on the motion of objects (attract or repel)

Charge Launcher

4: Changes in Ecosystems and Interactions of Organisms with their Environments

4.1: Organisms are interdependent with one another and with their environment

4.1.A: All populations living together within a community interact with one another and with their environment in order to survive and maintain a balanced ecosystem

4.1.A.b: Identify and describe different environments (i.e. pond, forest, prairie) support the life of different types of plants and animals

Forest Ecosystem
Pond Ecosystem

4.2: Matter and energy flow through an ecosystem

4.2.A: As energy flows through the ecosystem, all organisms capture a portion of that energy and transform it to a form they can use

4.2.A.a: Classify populations of organisms as producers and consumers by the role they serve in the ecosystem

Forest Ecosystem

4.2.A.b: Differentiate between the types of consumers (herbivore, carnivore, omnivore, detrivore/decomposer)

Forest Ecosystem
Prairie Ecosystem

4.2.A.c: Categorize organisms as predator or prey in a given ecosystem

Prairie Ecosystem
