5.B: The student is expected to: describe and classify samples of matter as solids, liquids, and gases and demonstrate that solids have a definite shape and that liquids and gases take the shape of their container;

Phases of Water

5.C: The student is expected to: predict, observe, and record changes in the state of matter caused by heating or cooling such as ice becoming liquid water, condensation forming on the outside of a glass of ice water, or liquid water being heated to the point of becoming water vapor; and

Phases of Water

6: Force, motion, and energy. The student knows that forces cause change and that energy exists in many forms.

6.A: The student is expected to: explore different forms of energy, including mechanical, light, sound, and thermal in everyday life;

Energy Conversions

8: Earth and space. The student knows there are recognizable patterns in the natural world and among objects in the sky.

8.B: The student is expected to: describe and illustrate the Sun as a star composed of gases that provides light and thermal energy;

Radiation

8.C: The student is expected to: construct models that demonstrate the relationship of the Sun, Earth, and Moon, including orbits and positions; and

Phases of the Moon

8.D: The student is expected to: identify the planets in Earth's solar system and their position in relation to the Sun.

9: Organisms and environments. The student knows and can describe patterns, cycles, systems, and relationships within the environments.

9.B: The student is expected to: identify and describe the flow of energy in a food chain and predict how changes in a food chain affect the ecosystem such as removal of frogs from a pond or bees from a field; and

Prairie Ecosystem

10: Organisms and environments. The student knows that organisms undergo similar life processes and have structures that help them survive within their environments.

10.A: The student is expected to: explore how structures and functions of plants and animals allow them to survive in a particular environment; and
