Reliable, Accurate Resources,&The Metric System
By Jonathon Latora and Anthony Siletti

Reliable and Accurate Resources
Reliable Resource
Something that can be relied on, but may not be necessarily correct.
For example, Wikipedia

Accurate Resource
Accurate Resource
Something that is always correct
For example, someone who was in a battle of a war, knows more about it than the person who studied it.

Differences and Between Accurate and Reliable resource
In the Accurate Resource, the information is correct.
But in a Reliable resource, the information can be misleading OR incorrect.

Metric System
What is the metric system?
The metric system is the standard system used by scientists.
What is the metric system used for?
Scientists use metric units to measure length, volume, mass, density and temperature.

Length
Length is one of the measurements that the metric system measures.
The basic unit of length measurement is the meter.
Anything smaller than a meter is measured in centimeter
anything larger than a meter is measured in kilometer.
What tools do you use to measure length?
You can use a meter stick, or a metric ruler.

Volume
Volume is the amount of space an object takes up.
The basic unit of volume is the liter.
Liquid is measured in milliliters or mL.
A solids volume is measured in cubic centimeters, (cc or cm3)
What tools are used to measure volume?
Tools used to measure volume are graduated cylinders with irregular solids, or use a metric ruler to find the length, width, and height and multiply them for right solids.

Mass
Mass is the amount of matter in an object.
The basic unit of mass is the kilogram.
Objects smaller than a kilogram are measured in grams.
Objects smaller than a gram are measured in milligrams.
What is mass measured in?
Mass is measured using the triple beam balance.

Density
Density is the mass per unit volume of a substance
Density is measured in 1g/cm3
D = M/V

Temperature
Temperature is the measure of the motion of molecules
Temperature in the metric system is measured in Celsius.
What tools do you use to measure temperature?
Temperature is measured using a thermometer.
