|---|---|---|---|---|---|
| physical properties | measurable characteristics that describe the physical state of something; includes mass, magnetism, temperature, density, luster and conductivity
🗑
|
||||
| metals | elements to the left side of the stair step line on the Periodic Table; typically solid, shiny, malleable, and good conductors of heat and electricity
🗑
|
||||
| non-metals | elements to the right side of the stair step line on the Periodic Table; typically dull, brittle, and poor conductors of heat and electricity
🗑
|
||||
| metalloids | elements along the stair step line on the Periodic Table; have properties of both metals and non-metals; also called semi-conductors
🗑
|
||||
| luster | how a material reflects light; shiny objects reflect a lot of light; dull objects do not reflect much light
🗑
|
||||
| conductivity | the ability of a substance to transfer heat or electrical energy
🗑
|
||||
| malleability | the ability of something to be shaped without breaking; example - aluminum foil
🗑
|
||||
| ductility | the ability of something to be pulled into a wire
🗑
|
||||
| brittle | breaks easily
🗑
|
||||
| poor conductor | a material that does not transfer heat or electrical energy very well
🗑
|
||||
| good conductor | a material that easily transfers heat or electrical energy
🗑
|
||||
| semi-conductor | a material that transfers heat and electrical energy better than a non-metal but not as well as a metal; the foundation of modern electronics
🗑
|
||||
| matter | anything that has mass and takes up space
🗑
|
||||
| density | the relationship between mass and volume; calculated using the formula D = m/v
🗑
|
||||
| volume | the amount of space an object occupies; for a rectangular prism calculated V = lwh
🗑
|
||||
| displacement | a method for calculating the volume of oddly shaped objects using a graduated cylinder and water; subtract the after water level from the before water level to find the volume
🗑

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.
