RI.PS1. Physical Science: All living and nonliving things are composed of matter having characteristic properties that distinguish one substance from another (independent of size or amount of substance).
PS1 (5-8) INQ-1. Investigate the relationships among mass, volume and density.
PS1 (7-8)-1. Students demonstrate an understanding of characteristic properties of matter by...
1a. Measuring mass and volume of both regular and irregular objects and using those values as well as the relationship D=m/v to calculate density.
RI.PS2. Physical Science: Energy is necessary for change to occur in matter. Energy can be stored, transferred, and transformed, but cannot be destroyed.
PS2 (5-8) INQ+SAE+POC-7. Use data to draw conclusions about how heat can be transferred (convection, conduction, radiation).
PS2 (7-8)-7. Students demonstrate an understanding of heat energy by...
7a. Designing a diagram, model, or analogy to show or describe the motion of molecules for a material in a warmer and cooler state.
7b. Explaining the difference among conduction, convection and radiation and creating a diagram to explain how heat energy travels in different directions and through different materials by each of these methods.
PS2 (5-8)-SAE+ POC-6. Given a real-world example, show that within a system, energy transforms from one form to another (i.e., chemical, heat, electrical, gravitational, light, sound, mechanical).
PS2 (7-8)-6. Students demonstrate an understanding of energy by...
6a. Using a real world example to explain the transfer of potential energy to kinetic energy.
6b. Constructing a model to explain the transformation of energy from one form to another. (e.g. an electrical circuit changing electrical energy to light energy in a light bulb).
6c. Explaining that while energy may be stored, transferred, or transformed, the total amount of energy is conserved.
