WHAT ABOUT UNITS OF MEASURE?

The International System of Units (SI) English Customary Weights and Measures also called Metric System (a base 10 system) also called US Customary Units Fluids: liters Fluids: ounce, cup, pint, quart, gallon Distance: meters Mass: grams Temperature: Celsius or Kelvin Distance: inch, feet, yard, mile Mass: ounce, pound, ton Temperature: Fahrenheit Prefixes: kilo, hecto, deca, deci, centi, milli, micro, etc. In science, we use the metric system!

Remember how to find the volume of a regular object? Volume = Length x Width x Height

Complete the data table. Measurement Volume of a glass of water Length of a sheet of paper Mass of a liter of milk Volume of an irregular solid Mass of a hockey puck Volume of 20 g of alcohol Mass of salt crystals Volume of a cube Tool to Use Unit to Use graduated cylinder milliliters metric ruler centimeters digital scale or triple beam balance grams graduated cylinder milliliters digital scale or triple beam balance milligrams metric ruler centimeters

Measuring Properties of Matter Lab Each table group will work together as a team Take turns letting everyone measure (work cooperatively) Each teams will visit six lab stations labeled A, B, C, D, E, and F.

Lab Procedures One team per station (if all stations are busy, sit back at your table and wait patiently) Only bring your lab sheet and pencil to stations (make sure chairs are tucked in and items are out of walkways) Use a quiet voice while completing the lab Absolutely, no horse-play! When you complete a station, put all materials back the way you found them (clean up) When you finish, sit back at your table and discuss your results with team

Station A There are two objects (Object A and Object B) located at this station. Using the measurement tools located at this station, measure the length in the units required. 16. Record the length of object A in mm. 17. Record the length of object B in cm.

Station B There are two objects (Object A and Object B) located at this station. Using the measurement tools located at this station, measure the mass using metric units. 18. Record the mass of object A. 19. Record the mass of object B.

Station C There are two beakers at this station that are filled with a colored liquid. They are labeled Liquid A and Liquid B. Using the graduated cylinders, measure the volume of both liquids. Be careful not to spill and make sure to put items back the way you found them (liquid in beakers, not cylinders) 20. Record the volume of the liquid A. 21. Record the volume of the liquid B.

Station D There is only one object located at this station. Using the measurement tools located at this station, find the mass and volume of this object. Hint: Volume = length x width x height 22. Record the mass of the object. 23. Record the volume of the object.

Station E There is only one object (a colored liquid) located at this station. Using the graduated cylinder located at this station, find the volume of this object. Be careful not to spill and make sure to put items back the way you found them (liquid in beakers, not cylinders) 24. Record the volume of the object.

Station F There is only one object (a colored liquid) located at this station. Using the graduated cylinder located at this station, you must measure exactly 100 m. L of the liquid in the graduated cylinder. Next, record the mass of this liquid in the graduated cylinder. To find out the mass of just the liquid, you must then weight the emptied graduated cylinder and subtract this value from your initial value. Hint: Mass(grad. cylinder with liquid) – Mass (grad. cylinder empty) = Mass of liquid Be careful not to spill and make sure to put items back the way you found (liquid in beakers, not of cylinders) 25. them Record the mass of 100 m. L the liquid.

Reflection Questions What are some mistakes that can be made when measuring mass? Do all objects have the same amount of mass? How did you measure length? How did you measure mass? How did you measure volume?
