Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans.

Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.

Construct an explanation to describe how animals receive different types of information through their senses, process the information in their brains, and respond to the information in different ways.

Use evidence to construct an explanation relating the speed of an object to the energy of that object.

Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
