🗑
|
||||
| positive | electrical charge (+)

🗑
|
||||
| repel | push away, same charges
🗑
|
||||
| neutral | no charge
🗑
|
||||
| humidity | wetness in the air
🗑
|
||||
| static electricity | the buildup of electrical charge
🗑
|
||||
| jump | when charge builds up so much it goes from the cloud to the ground
🗑
|
||||
| discharge | the movement of static electricity into an object, ZAP!
🗑
|
||||
| conductors | material that electricity flows through easily (metal, water)
🗑
|
||||
| insulators | material that electricity doesn't flow through easily (wood, air, rubber)
🗑
|
||||
| lightning | a huge discharge of static electricity from a cloud
🗑
|
||||
| circuit | path that electricity flows through
🗑
|
||||
| current electricity | electricity that flows through a circuit
🗑
|
||||
| closed circuit | a path with no holes, electricity can flow through it
🗑
|
||||
| open circuit | a path with holes, electricity cannot flow through it
🗑
|
||||
| switch | tool that can make a circuit open or closed
🗑
|
||||
| amperes | the measure of how many electrons flow past a place in a circuit
🗑
|
||||
| resistor | allows electrical energy to turn into heat or light
🗑
|
||||
| short circuit | a side circuit with low resistance, accidentally made
🗑
|
||||
| dry cell | changes chemical energy into electrical energy
🗑
|
||||
| wet cell | has electrodes, changes chemical energy into electrical energy
🗑
|
||||
| electrodes | negative and positive terminals of a wet cell
🗑
|
||||
| series circuit | many objects next to each other on a circuit, electricity is shared
🗑
|
||||
| parallel circuit | each object has its own circuit, electricity has 2 paths to travel through
🗑
|
||||
| fuse | has a piece of metal that will heat up and melt and make an open circuit
🗑
|
||||
| circuit breakers | switch that will make an open circuit when electricity flows through it
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
