|---|---|---|---|---|---|
| Triple beam balance | Measures the mass of an object.
🗑
|

| Graduated cylinder | Measures volume of an object.
🗑
|
||||
| Flask | Holds or mixes chemicals.
🗑
|
||||
| Were your safety googles when: | When working with heat, working with chemicals or tour teacher tells you to.
🗑
|
||||
| Most important safety rule: | Listen to your teacher and follow all instructions very carefully.
🗑
|
||||
| D=M/V | Formula to find density. Density=mass/volume
🗑
|
||||
| Chemical change | Chemical reaction takes place, the object becomes a whole new material with new and different properties.
🗑
|
||||
| Chemical change indicators | color change, gas produced, solid precipitate produced, heat or light produced and temperature absorbed.
🗑
|
||||
| Physical change | are changes affecting the form of the object, but the object still the same.
🗑
|
||||
| Parts of an atom and its charge | Protons(positive charge), neutrons(no charge, electrons(negative charge)and electron shells.
🗑
|
||||
| The periodic table is arrange by... | increasing atomic number.
🗑
|
||||
| Chemical equations | A way of describing a chemical reaction.
🗑
|
||||
| Balanced force | All forces acting on an oject are equal, and causes no change.
🗑
|
||||
| Unbalanced force | All forces acting on the object aren't equal, there will be a change in motion.
🗑
|
||||
| Newton's 1st law | An oject at rest remains at rest, and an oject in motion remains in motion with the same speed and direction.
🗑
|
||||
| Newton's 2nd law | Acceleration of an object depends on the mass of the object and the amount of force applied to the object.
🗑
|
||||
| Newton's 3rd law | for every action, there is an equal and opposite reaction.
🗑
|
||||
| S=D/T | Formula to find speed. Speed=Distance/Time
🗑
|
||||
| Same distance, more time in a speed graph. | No movement.
🗑
|
||||
| Same speed, more time in a acceleration graph. | Constant speed.
🗑

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.
