Energy Transfer
Science Unit 1 Lesson 3
| Question | Answer |
|---|---|
| What is the transfer of thermal energy from one object to another? | Heat |
| What is heat? | The transfer of thermal energy from one object to another |
| What 3 ways does heat flow? | Conduction, convection, or radiation |
| What is radiation? | Energy that travels as a wave |
| What is energy that travels as a wave? | Radiation |
| ALL matter is made of… | Moving particles |
| When you use a thermometer, you are measuring…. | The kinetic energy of something (temperature) |
| When the temperature is higher particles move… | Faster |
| When heat is transferredWhat to an object, what happens to the object’s particles? | They move faster |
| How is energy carried from the sun? | Radiation |
| What happens when radiation carries sun to your skin? | It feels hot |
| What does the sun do to the particles of your skin? | Make them move faster (so they get hotter) |
| What kind of energy does an object have if it is a source of light? | Light energy |
| What is light energy? | A form of energy we can see |
| What is a form of energy we can see? | Light |
| What radiates light to the Earth? | The sun |
| What objects give off light energy that we can see at night? | Stars |
| What does generate mean? | Produce |
| What word means produce? | Generate |
| What animal can generate light energy? | Jellyfish |
| What kind of energy can we hear? | Sound energy |
| What causes sound? | Vibration through matter |
| Where can sound travel? | Solids, liquids, or gasses |
| How is sound described? | Pitch |
| What is pitch? | How high/low a sound is |
| If a sound has a high pitch vibrations are moving… | Fast |
| If a sound has a low pitch, vibrations are moving… | Slow |
| Which pitch has faster moving vibrations? | High |
| How does sound energy move? | Outward from the source |
| What is a wave? | How energy is transferred |
| What direction do sound waves move? | All directions |
