Support an argument that the gravitational force exerted by Earth on objects is directed down.
Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.
Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.
Use mathematical representations of Newton’s Law of Gravitation and Coulomb’s Law to describe and predict the gravitational and electrostatic forces between objects.
Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.
Develop a model to describe that matter is made of particles too small to be seen.
Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
Use models to describe that energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun.
Obtain and combine information about ways individual communities use science ideas to protect the Earth’s resources and environment.
