  1. Measurement Take Me To Your Liter SMI3P1

  2. Essential Question • What unit is used to describe the volume of liquid in a container? SMI3P1

  3. Vocabulary • capacity – how much liquid something can hold when it is completely full • vial – a small container of plastic or glass SMI3P1

  4. Task • You are to fill the vial with water and then dump the water in the cup. • Keep track of how many vials of water you dump into the cup. • Take turns started with the collectors, then the encouragers, then the reporters and finally the getters. Reporters should make tallies to keep track of how many vials of water are poured into the cup. SMI3P1

  5. Compare Results • GroupCapacity in Vials SMI3P1

  6. Liter and Milliliter • liter (l)is the metric standard used worldwide for measuring volume. • Volume refers to the space occupied by something. • Because the liter is a large volume, it is difficult to use it to measure the volumes of small containers like plastic cups and vials, so the liter has been subdivided into 1,000 parts called milliters (ml). SMI3P1

  7. Measuring a liter • Getters get a 100-ml beaker. • Encouragers pour water into the beaker until it holds exactly 100 ml. • Reporters bring the beaker of water up the the front of the room and pour it carefully into the 1-liter beaker. • We will tally how many 100-ml beakers of water it will take to fill the 1-liter beaker. SMI3P1

  8. Vocabulary • Volume – the three-dimensional space occupied by something. • Capacity – the volume of fluid (such as water) a container can hold when full. • liter (l) – the metric standard for measuring volumes of fluids • milliliter (ml) – 1/1,000 of a liter, 1,000 milliliters equals 1 liter (1 milliliter equals 1 cubic centimeter) SMI3P1

  9. Content/Inquiry • How many milliliters are in 1 liter? (1,000) • How many 100-ml beakers does it take to make 1 liter? (10) • What units would you use to measure the capacity of a bathtub? (Liters) SMI3P1

  10. Essential Question • What unit is used to describe the volume of liquid in a container? • The Liter is used to describe the volume of liquid in a container. SMI3P1
