Forms of Energy/Electricity
| Question | Answer |
|---|---|
| Know the difference between Kinetic and Potential Energy. Be able to explain how they are related. | Kinetic Energy is energy due to motion. Kinetic energy depends on its speed and mass. The faster it is moving or the more mass it has, the more kinetic energy is produced. Potential Energy is energy that is not causing changes now but could in the futu |
| Understand energy transformation (Conservation of Energy) – Energy can’t be created or destroyed, only transformed. Be able to give an example and understand examples given. | Energy can’t be created or destroyed, only transformed. Fireworks have chemical energy that is transformed into light, sound and thermal energy. A lamp turns electrical energy into thermal and light energy. Your body turns chemical energy of your food i |
| Know and be able to define the different types of energy (chemical, thermal, and nuclear | Chemical – found in the bonds holding molecules together. (Battery, Food, Match) Nuclear – holds the nucleus of an atom together. (Fission, Fusion) Mechanical – objects in motion or stretching. (Scissors, Gears, Bending arm) Thermal – The total of all |
| Know and be able to define the different types of energy ( electrical, mechanical, vibrational, light, and sound). | Electrical – Eneergy of moving electrical charges. (Electricity, Static) Vibrational – Rapid back and forth motion of an object. (Pluck a rubber band, Guitar strings) Light – Electromagnetic radiation(combination of electrical and magnetic energy) (Lamp |
| Understand frequency and amplitude and how wavelength and crests are related to them. | Frequency - The number of crests that pass by a point in one second. The distance between waves. The grater the frequency the higher the pitch; the lower the frequency, the lower the pitch. Amplitude – The amount of energy carried by a wave. The heigh |
| Review what happens to light when it enters either a convex or concave lens. | Convex – The light focuses to a point when exiting the lens. Concave – the light spreads out when exiting the lens. |
| Be able to explain that ROY G BIV is the colors in the visible light spectrum and that it stands for Red, Orange, Yellow, Green Blue, Indigo, and Violet. | ROY G BIV is the colors in the visible light spectrum and that it stands for Red, Orange, Yellow, Green Blue, Indigo, and Violet, in order from lowest to highest frequency. |
| Be able to explain why a yellow shirt looks yellow and why a black pencil case looks black. | A yellow shirt absorbs all the colors of the visible light spectrum, EXCEPT yellow, which bounces back to your eye. A Black pencil case absorbs ALL the colors in the visible light spectrum, and nothing is reflected back to your eye, so you see it as blac |
| Know how sound waves travel and why they travel faster or slower through the 3 phases of mater. | Sound is vibrating particles. The closer the particles are together, the faster it can travel through them. Sound travels fastest in a solid, then a liguid, and slowest in a gas. |
| Can sound and light travel through space? Be able to explain your answer. | Sound can not travel in space because there are no particles to vibrate. Light can travel in space because it is a combination of electric and magnetic energy. |
| Be able to understand and define heat transfer through radiation, convection, and conduction. Be able to give an example of each. | Radiation – transfer of heat through electromagnetic radiation. (Sun, Greenhouse) Convection – The transfer of heat through moving gasses or liquids. ( Pool, A/C) Conduction – The transfer of heat through objects that are touching. (Stove, Soda can) |
| Know that thermal energy naturally flows from hot to cold until both objects are the same temperature. | HOT to COLD |
| Chemical Energy | found in the bonds holding molecules together. (Battery, Food, Match) |
| Nuclear Energy | Nuclear – holds the nucleus of an atom together. (Fission, Fusion) |
| Mechanical Energy | Mechanical – objects in motion or stretching. (Scissors, Gears, Bending arm) |
| Thermal Energy | Thermal – The total of all kinetic and potential energy in an object, heat. (Candle, Match, Human Body) |
| Electrical Energy | Electrical – Energy of moving electrical charges. (Electricity, Static) |
| Vibrational Energy | Vibrational – Rapid back and forth motion of an object. (Pluck a rubber band, Guitar strings) |
| Light Energy | Light – Electromagnetic radiation(combination of electrical and magnetic energy) (Lamp, Sun) |
| Sound Energy | Sound – A wave of vibrations spreading outward from a source. (Speaker, Voice) |
| Know about how atoms get charged and why they become either Positive(+) or Negative(-). | An atom becomes charged when it gains or loses electrons. If an atom loses electrons it becomes positive, if it gains electrons it becomes negative. |
| Conductor | a material through which an electrical charge can move easily. (Copper, gold, silver, aluminum, and graphite) |
| Resistor | a material that resists, or slows, the flow of electrical energy. When electricity flows through a resistor some is turned into thermal energy. (Light bulb, radio, TV) |
| Insulator | a material that is such a strong resistor that it can stop the flow of electricity. (Rubber, plastic, glass, and Dry cotton) |
| Know and be able to explain the different parts of a circuit. Remember that simple and complex circuits have the same parts Power source -. | an electrical socket, or battery that provides the electricity |
| Know and be able to explain the different parts of a circuit. Remember that simple and complex circuits have the same parts. Insulator - | rubber, plastic or cloth that keep the electric charges inside the pathway (conductor). |
| Know and be able to explain the different parts of a circuit. Remember that simple and complex circuits have the same parts. Switch - | Switch – control the flow of electricity by either opening or closing pathways. |
| Know and be able to explain the different parts of a circuit. Remember that simple and complex circuits have the same parts. Conductor - | Conductor – a pathway for electrical charges to flow through. |
| Know and be able to explain the different parts of a circuit. Remember that simple and complex circuits have the same parts. Resistor - | Resistors – transform electrical energy into another form such as light, thermal, and sound. |
| Know that simple circuits only have one path for the electrons (electricity) to flow through and that complex circuits have more than one. | Simple circuit – one pathway for electrical current. If any part breaks or is opened, the electrical energy cannot flow to the rest of the circuit. Parallel circuit – more than one pathway for the flow of electrical current. If one pathway is damaged e |
| Be able to read and draw both a series circuit and a parallel circuit. (Circuit Diagrams) | Pages 484 to 486. |
| Know the symbols used in a common circuit diagram. | Page 486. |
| Know the electrical safety rules in the purple rectangle on page 487. | Don’t touch electrical outlets and cover when not in use. Don’t unplug cords by yanking on them. Repair or replace damaged electrical cords. Never touch a downed power line. Never touch or operate cord-operated electrical equipment near water. |
| Know the differences between a regular magnet and an electromagnet. | 1. An electromagnet can be turned on and off, a regular magnet can not. 2. An electromagnet can be made stronger or weaker, a regular magnet can not. 3. An electromagnet’s poles can be easily changed, a regular magnet’s can not. |
| Know the three ways to make an electromagnet stronger. | 1. Increase the number of wire coils in an electromagnet. 2. Increase the power flowing through an electromagnet. 3. Place a iron rod through the coils of an electromagnet. |
| Know what a superconductor is. | A material with n resistance to electrical current. This usually only happens at super cold temperatures, so it is difficult to produce a superconductor outside of a lab. |
| Know what current is. | The flow of electrical charges through a material. |
| Reread and understand about the balloon and why it sticks to your hair on page 479. | When the balloon is rubbed on the hair, some electrons from the hair break away from the hair and stick to the rubber in the balloon. This makes the hair positively charged and the balloon negatively charged and they stick together. |
| Know that the flow of electricity (electrons) is from negative (−) to positive (+). | The flow of electricity (electrons) is from negative (−) to positive (+). |
