|---|---|---|---|---|---|
| Energy | ability to do work or cause change
🗑
|
||||
| Thermal energy | Energy that comes from heat. It is produced by the Sun and is needed for life on Earth.
🗑
|
||||
| flow | the transfer of energy
🗑
|
||||
| refraction | Bending of light. When light hits and travels through a different medium, the light is bent.
🗑
|
||||
| Light spectrum | the range of electromagnetic wavelengths that our eyes can see (ROYGBIV)
🗑
|
||||
| Mechanical energy | the energy an object has due to its position or motion. "Movement" and can be used for things such as turning a wheel, peddling a bike, raising a flag, etc.
🗑
|
||||
| Electrical circuit | the path an electric current takes
🗑
|
||||
| Electrical current | The continuous flow of electricity through a conductor
🗑
|
||||
| Lens | A piece of glass or other transparent material that lets light pass through it
🗑
|
||||
| Magnify | To make something appear larger than it is with a lens or microscope
🗑
|
||||
| Light energy | Energy that people can see. Can be produced by the Sun, fire, batteries or the result of a complete electrical circuit
🗑
|
||||
| Electromagnetism | Magnetism produced by an electric current
🗑
|
||||
| Mirror | A surface that reflects light.
🗑
|
||||
| Kaleidoscope | A tube-shaped toy that is rotated to produce designs with reflected light using bits of colored glass at one end of the tube.
🗑
|
||||
| Sound energy | A form of energy where vibrations travel through solids, liquids and gases and are detected by the organs of hearing.
🗑
|
||||
| Conductor | A material through which electricity flows
🗑
|
||||
| Laser | A device that produces an intense beam of light.
🗑
|
||||
| Telescope | An instrument for viewing distant objects by refracting light rays through a lens
🗑
|
||||
| Insulator | Material that slows down or stops electric current or heat from flowing
🗑
|
||||
| Reflection | Light bouncing off of an object. When light hits a surface and bounces back.
🗑
|
||||
| Illuminate | To brighten with light
🗑
|
||||
| Electrical energy | Can be achieved through the creation of a complete circuit. This can be seen when anything is plugged into an electric circuit. We depend on this type of energy to power lights, appliances, and some cars.

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.
