# Gr 6 Metric System

### Metric System, Volume, Density, Displacement, Sink or Float

Question | Answer |
---|---|

The amount of matter in an object is called its ____ . | Mass |

The amount of space an object takes up is called its ______. | Volume |

The amount of matter in the volume is an object's ___________ . | Density |

The measure of the force of gravity pulling an object down to the earth is the object's ______________ . | Weight |

What is the formula used to find the volume of a solid object? | V = L x W x H |

What is the formula used to find the density of an object? | D = Mass divided by Volume |

If a brick has a volume of 48 cubic centimeters and a mass of 144 grams, what is its density? | D = 144g ÷ 48 cm3 = 3 g/cm3 |

What tool can we use to measure length, width, and height of an object? | A ruler |

What tool can we use to measure the amount of matter or mass in an object? | triple beam balance |

What tool can we use to measure liquids and also the volume of irregularly shaped objects? | graduated cylinder |

Metric units used to measure liquids include | milliliters, liters |

Metric units used to measure the mass (amount of matter) in an object | grams, kilograms |

What does the scientific principle of water displacement say? | No two objects can occupy the same space at the same time. That's why liquids move out of the way when an object is dropped into it, and the level rises. |

True or False: The weight of an object does not remain constant (does not stay the same) if its location is changed from earth to the moon. | True. The weight changes because the force of gravity on the moon is less than it is on earth |

To find the volume of a car, you would________________ . | Multiply length x width x height |

The weight of an object is really a measure of the _______________. | Force of gravity pulling it downward to earth |

If the density of an object is GREATER than the liquid in which we drop it, then the object will ____________ | Sink |

If the density of an object is LESS THAN the density of the liquid in which we drop it, then the object will ___________ . | Float |
