|
|
|
When an object............. it causes the air particles around it to ....... |
Vibrate and moves |
|
|
|
Circuits need to be............ for them to work properly |
Complete |
|
|
|
This means that the wires must go in a full.... Around from the power source and back again |
Loop |
|
|
|
Circuits that are not complete will not work because the electricity can not...... Around them properly |
Travel |
|
|
|
If you are using more than one battery in a circuit they all have to be facing the same......... in the circuit |
Direction |
|
|
|

|
|
|
You can change circuits by adding more....., or adding more cells which means batteries |
Bulbs |
|
|
|
If you add more bulbs to a circuit, the bulbs will grow less brighter ...... ,because the bulbs have to share the electricity that the battery provides |
Dimmer |
|
|
|
Adding more batteries in series to a circuit will make the bulbs grow........ Because there is more electric power |
Brighter |
|
|
|
You can also change a circuit by changing the....... Of a connecting wire |
Length |
|
|
|
As the wire gets longer, the bulbs get....... Making the wire shorter make bulbs get brighter |

|
|
|
Why do batteries have positive and negative ends |
Because energy flow from negative and positive |
|
|
|
If a bulb burns out or a wire is cut what will happen to the flow of electricity |
The flow will stop |
|
|
|
Reflection |
Bounces off |
When light bounces at the same angle it hits like, objects that best reflect light are smooth shiny surfaces |
|
|
When light is refracted the light wave is |
Bent |
Refraction occurs when light passes through a new medium |
|
