|---|---|---|---|---|---|
| What sorts of things can be a medium? | Matter (solids, liquids, gases)
🗑
|
||||
| How does sound travel? | Sound travels through a medium
🗑
|
||||
| How is sound made? | Sound is produced by vibrating objects
🗑
|
||||
| What is sound energy? | Sound waves (vibrating air)
🗑
|
||||
| What are some forms of energy? (Name 7) | Sound, Light, Heat (thermal), Chemical, Mechanical, Kinetic, Potential
🗑
|
||||
| Can energy be transferred? | Yes. Energy can be transferred from one form to another,
🗑
|
||||
| What is Energy? | The ability to cause motion or create change
🗑
|
||||
| Can sound travel through a vacuum? Why or why not? | No. A vacuum is an absence of matter
🗑
|
||||
| In sound energy what is pitch? | Pitch is how high or low a sound is. The more something vibrates in a specific amount of time, the higher the frequency of sound waves and the higher the pitch
🗑
|
||||
| In sound energy what is volume? | How loud or soft a sound is
🗑
|
||||
| In sound energy what is an echo? | Sound waves bouncing off of a hard surface
🗑
|
||||
| In which direction does light normally travel? | Light travels in a straight line - unless it strikes an object or it travels from one medium to another
🗑
|
||||
| Name 3 things that can happen to light when it strikes an object? | 1. Refracted (bends) when it goes from one transparent medium to another
2. Reflected (bounces back) when it hits an object
3. Absorbed (light that hits an object & is absorbed turns into heat the rest is reflected-this is what allows us to see colors)
🗑
|
||||
| What happens when light hits a prism? | Light is refracted (bent)
🗑
|
||||
| What happens when light hits a mirror? | Light is reflected (bounces back)
🗑
|
||||
| Does a black or white shirt keep us cooler in the summer? Why? | A white shirt because it reflects every color on the spectrum. A black shirt absorbs all of the colors of light (holds heat)
🗑
|
||||
| What is electricity? | The movement of electrons that can produce light, heat and sound
🗑
|
||||
| What is an electron and where would you find one? | Negatively charged particles in an atom
🗑
|
||||
| What is static electricity? | A negative charge jumps to a positive charge
🗑
|
||||
| How is heat energy measured? | With thermometers
🗑
|
||||
| What is mechanical energy? | Any energy that has the ability to do work
🗑
|
||||
| What is kinetic energy? | The energy of movement (rolling ball, light, sound)
🗑
|
||||
| What is potential energy? | Stored energy (water held in a tank, a ball at the top of a hill)
🗑
|
||||
| What is thermal energy? | Energy that tranfers forms (states) gives off heat
🗑
|
||||
| What can heat (or its absence) do to matter? | It can cause it to change states
🗑
|
||||
| What happens when heat is removed from gases? | Gases turn to liquids (steam to water)
🗑
|
||||
| What happens when heat is removed from liquids? | Liquids turn to solids (water to ice cubes)
🗑
|
||||
| What happens when heat is added to solids? | Solids turn to liquids (melt - ice cubes to water)
🗑
|
||||
| What happens when heat is added to liquids? | Liquids turn to gas (steam)
🗑
|
||||
| What happens to light when it hits a blacktop (pavement)? | Light is absorbed (and turns into heat)
🗑
|
||||
| Is energy matter? | Energy is NOT matter; it is not a solid, liquid, or gas (which all have mass)
🗑
|
||||
| What often happens when energy is transferred from 1 form to another? | Energy releases heat
🗑
|
||||
| Sound travels travels through a medium. Give an example of a medium. | A medium can be any form of matter (solids, liquids, gases)
🗑
|
||||
| T/F The higher the frequency of sound waves, the higher the pitch | T
🗑
|
||||
| Give an example of an insulator | Rubber, plastic, wood, glass
🗑
|
||||
| Give an example of a conductor | Water, metal, air
🗑
|
||||
| Are humans conductors or insulators? | Conductors
🗑
|
||||
| T/F Every magnet has 2 poles | True
🗑
|
||||
| Name the poles of a magnet | North and South
🗑
|
||||
| Same poles repel or attract? | Repel
🗑
|
||||
| South facing North poles repel or attract? | Attract
🗑
|
||||
| What materials are magnetic? | Only iron, nickel or cobalt (or any material made with these ingedients like steel)
🗑
|
||||
| Is steel magnetic? | Yes
🗑
|
||||
| What happens to an electromagnet when electricity is turned off? | It is no longer magnetic - the magnetism stops
🗑
|
||||
| What is an electromagnet? | An object that becomes a magnet when electricity passes through it
🗑
|
||||
| What shape do wires in an electromagnetic circuit need to be? | Coiled (around an iron core)
🗑
|
||||
| What does an electrical circuit need for an electric current to flow? | A complete unbroken loop of conductors with a power source
🗑
