  1. Does this make sense to you?

  2. The Metric System The metric system is a system of measurement that is based on the number ten It is often used in science and in countries around the world

  3. Why do we use the metric system? The metric system can be used to measure mass, volume, length, and temperature

  4. But how is it any different? The English System (our system) uses feet, ounces, gallons and Fahrenheit The metric system uses meters, grams, liters and Celsius

  5. Length Ruler

  6. What is Length? It is the measured distance between two points Distance between two points

  7. Length can also be referred to as width, height, or distance, depending on how it is used. A ruler is used to measure distances between objects.

  8. Mass Triple Beam Balance

  9. Mass tells us HOW MUCH matter there is. It is measured in grams. Example – 5 grams of salt 10 kilograms of feathers

  10. Matter – anything that has mass and takes up space. It is found in three different states. Examples: Gas Solid Liquid

  11. A Triple Beam Balance is the lab equipment used to measure mass. Measurements are expressed in GRAMS

  12. Volume Graduated Cylinder/Ruler

  13. How does one measure volume? Volume describes how much SPACE an object takes up. Volume can change depending on the state of matter. Solids and liquids have a constant volume, gases change based on the size of the container

  14. There are two methods Graduated Cylinder Ruler Used to measure the volume of a liquid OR an irregularly shaped object (like a jagged rock) Can be used to measuring and then multiplying the length, width, and height of an object. Volume = L x W x H

  15. Temperature Thermometer

  16. What is Temperature? Temperature is a measure of how much energy an object contains. Measured in °Celsius or Kelvin. More energy = higher temperature

  17. Density

  18. Density – How much stuff is in a certain amount of space Objects that are more dense sink to the bottom Example – Dropping a rock in water - if the rock is MORE dense than the water, it sinks -if the rock is LESS dense than the water, it floats

  19. Density cannot be measured by one piece of lab equipment You need the MASS and the VOLUME Density = Mass Volume D = M/V Units – g/ml OR g/cm3

  20. The Magic Triangle

  21. Meter (m) Metric ruler Metric ruler or graduated cylinder Liter, cm3 = mL Triple-beam balance Grams (g) Tools for mass & volume g/ml or g/cm3 thermometer ºC or K
