NJ.5.2.4. Physical Science: Physical science principles, including fundamental ideas about matter, energy, and motion, are powerful conceptual tools for making sense of phenomena in physical, living, and Earth systems science.
5.2.4.A. Properties of Matter: All objects and substances in the natural world are composed of matter. Matter has two fundamental properties: matter takes up space, and matter has inertia.
Objects vary in the extent to which they absorb and reflect light and conduct heat (thermal energy) and electricity.
5.2.4.A.4. Categorize objects based on the ability to absorb or reflect light and conduct heat or electricity.
5.2.4.C. Forms of Energy: Knowing the characteristics of familiar forms of energy, including potential and kinetic energy, is useful in coming to the understanding that, for the most part, the natural world can be explained and is predictable.
Light travels in straight lines. When light travels from one substance to another (air and water), it changes direction.
5.2.4.C.4. Illustrate and explain what happens when light travels from air into water.
5.2.4.E. Forces and Motion: It takes energy to change the motion of objects. The energy change is understood in terms of forces.
Motion can be described as a change in position over a period of time.
5.2.4.E.1. Demonstrate through modeling that motion is a change in position over a period of time.
There is always a force involved when something starts moving or changes its speed or direction of motion. A greater force can make an object move faster and farther.
5.2.4.E.2. Identify the force that starts something moving or changes its speed or direction of motion.
