SC 03.17 Understands_how_energy_can_be_transformed,_transferred,_and_conserved.

- classifying the changes (i.e., heat, light, sound, and motion) that electrical energy undergoes in common household appliances (i.e., toaster, blender, radio, light bulb, heater).
- recognizing that energy can exist in many forms (i.e., heat, light, chemical, electrical, mechanical).

SC 03.19 Motions,_forces,_their_characteristics,_relationships,_and_effects.

- investigating that the greater the force acting on an object, the greater the change in motion will be. (L)
- stating that every object exerts gravitational force on every other object.

- explaining that energy (i.e., heat, light, chemical, electrical, mechanical) can change form.
- identifying the initial source and resulting change in forms of energy in common phenomena (e.g., sun to tree to wood to stove to cabin heat).
- recognizing that most substances can exist as a solid, liquid, or gas depending on the motion of its particles.

SC 04.19 The student demonstrates an understanding of motions, forces, their characteristics, relationships, and effects:

- illustrating that unbalanced forces will cause an object to accelerate.

MA.06.12 (A5.3.1) Identify, classify, or compare regular and irregular polygons (using sides and angles). (GLE [6] G-1)

MA.06.13 (A5.3.4) Identifying, comparing, and describing attributes and properties of circles (radius, diameter, and Pi), the correct usage of a compass, and find area and circumference of a circle. (GLE [6] G-2)

MA.06.14 Identifies and describes triangular and rectangular prisms by bases, faces, edges, vertices; recognizes 3-D shapes from 2-D drawings. (GLE [6] G-3, G-4)

MA.08.20 (A5.4.6) Applies geometric formulas to a variety of situations (midpoint, distance, slope, area, and volume). (GLE [9] G-5, [10] G-6)

MA.08.21 Identifying, analyzing, comparing or using properties of angles (including supplementary and complementary) or circles (degrees in a circle) (GLE [9] G-1)
