Energy
In this unit, we will be examining how energy is what makes things move. We will start by examining the difference between stored energy, called potential energy, and energy in motion, called kinetic energy.
Next we will examine the forms of energy that are large, then work our way down to the forms of energy that are atomic sized.
Once we are finished with identifying the different forms of energy, we will examine how energy is transformed from one form of energy to another - i.e. electrical energy being converted to heat and light when we turn on a light bulb.
Next, we will examine how heat is transferred via conduction, convection and radiation - followed by the study of waves in sound and light.

When I am finished with Energy, I Can...
- I CAN compare the transfer of heat by conduction, convection, and radiation and provide examples of each.
- I CAN analyze the cyclical nature of potential and kinetic energy. (e.g. bouncing ball, pendulum)
- I CAN trace the conversion of energy from one form of energy to another. (e.g. light to chemical to mechanical
WAVES, LIGHT & SOUND OVERVIEW
- relate the energy of a wave to wavelength.
- compare the transfer of energy (i.e. sound, light, earthquake waves, heat) through various media.
- describe the spread of energy away from an energy producing source.
- demonstrate how white light is separated into the visible color spectrum.
- cite examples of how organisms sense various forms of energy.
- investigate and report the response of various organisms to changes in energy. (e.g. plant response to light, human response to motion, sound, light, insects’ response to changes in light intensity)
- investigate and describe how engineers have developed devices to help us sense various types of energy. (e.g. seismographs, eyeglasses, telescopes, hearing aids)
