Metrics in Science
This stack will help students study the use of metrics in Science.
Question | Answer |
---|---|
What is the metric system? | The metric system is a system of measurement based on the number 10. |
What is the "SI" units? | SI is the standard system of measurement that allows scientists to compare data and communicate with each other about results. |
List prefixes for the most common SI units | Common SI prefixes are: kilo-, hecto-, deka-, deci-, centi-, and milli-. |
What is the definition of "length"? | Length is the distance from one point to another. The basic unit of measure in the SI system is the meter (m). |
What is the definition of "mass"? | Mass is a measure of the amount of matter an object contains. The basic unit of measure in the SI system for mass is kilogram (kg). |
What is the formula for length? | The formula for length is LxWxH. |
What is the definition for "weight"? | Weight is a measure of the force of gravity acting on an object. |
What is the definition for "volume"? | Volume is the amount of space an object takes up. The basic unit of volume in the SI system is cubic meter (m3). |
What is the definition for "density"? | Density is a measure of how much mass is contained in a a given volume. |
What is the formula for density? | The formula for density is: Density = mass volume |
What are the two units of measure for temperature that scientists use? | The two units of measure that scientists use for temperature is Celsius(C) and Kelvin(K). We will use Celsius in our science class. |
Explain absolute zero. | Absolution zero is the 0 degree on the Kevlin measurement scale. It is the temperature when all molecules stop moving. (-273.16 degrees Celsius) |
What unit of measure do scientists use to measure mass and weight? | Scientists use grams to measure mass and weight. |
What unit of measure do scientists use to measure volume? | Scientists measure volume in liters or cubic meters. |
What unit of measure do scientists use to measure length? | Scientists measure length in meters. |
What scientific tool is used to measure mass? | To measure mass, a scientist would use a balance beam. |
Explain how weight is different than mass. | Weight is determined by the gravitational pull on an object and mass is determined by the amount of matter an object contains. |
How can you find the volume of an irregularly shaped object? | One can find the volume of an irregularly shaped object by using water displacement. |
How can you convert milliliters into centimeters? | One millimeter is the same amount of volume as a cubic centimeter. |
What type of experiment could we do to see the concept of density? | An experiment to see if items would sink or float would help to understand density. |
What does temperature really measure? | Temperature actually measures how fast atoms and molecules are moving in a particular substance. |
What is the average temperature for a human body? | The average temperature of a human body is 98.6 degrees Farenheit or 37 degrees Celsius. |
Put the following metric prefixes in order from least to greatest: milli-, kilo-, deci-, centi-, hecto-, and deka. | The metric prefixes from lease to greatest are: milli-, centi-, deci-, (meter), deka-, hecto-, and kilo-. |
