5. BrainPop We’ll watch as Tim and Moby explain the SI (metric) system of measurement.

6. I need 2 volunteers… I need two scholars to come to the front of the room for a short demonstration. It is your job to measure the distance from one wall to the other using the ruler in centimeters and report it back to the class when you are finished.

7. Guiding Questions Are there any other units that would be better to measure the distance from one wall to the other? What if we were measuring the distance from Arlington to Dallas? Would we use centimeters or meters? What is the common theme amongst all the units we’ve talked about so far?

9. What are SI Units? Scientists, and most of the world, use the International System of Measurement – SI Units. {Also known as the metric system. SI Units are a worldwide system of measurements that scientists have agreed to use in their work. This means that scientists all over the world in every country and in every language, use the SI system of measurement! The United States is one of the only countries who does not use the metric system as their standard measurements.

11. Each type of measurement in SI has a base unit. Such as meter for length/distance or seconds for time. Let’s take a look at the most common base units we will use in this class and what they measure. Base Units

12. Length is the measurement of how long something is. Distance is the measurement of how far something is. meter When scientists want to measure the length or the distance of something, they’re going to use the base unit, meter. The symbol for the meter is (m). – Lowercase for base units! Length/Distance

13. Mass is the amount of matter in an object. – It is not the same as weight! grams When scientists measure mass, they use grams. The symbol for the gram is (g). Mass

14. Volume is the amount of space an object takes up. liters When scientists measure volume, they use liters. The symbol for liters is (L). – The only base unit whose symbol is uppercase! Volume

15. Temperature is a measure of the average kinetic energy of particles. degrees Celsius When scientists measure temperature, they use degrees Celsius. The symbol for the Celsius is (°C). Temperature

16. We can think of time as the duration of an action or specific events of the past, present, and future. seconds When scientists measure time, they use seconds. The symbol for the seconds is (s). Time

17. Why do scientists think that using the metric system is easier than other systems of measurement? Think-Pair-Share

19. SI Prefixes A prefix is a letter or word that’s placed in front of another word to give it meaning. In SI Units, prefixes are added to base units to create larger and smaller units for that quantity.

20. To indicate measurements much larger or much smaller than the base unit, you add a prefix to the base unit label. – For example, adding milli- to liter is a milliliter. – Adding kilo- to meter makes a kilometer. SI Units are all powers of 10, that means that all prefixes indicate units that are 10 times larger, or smaller than the unit on either side of it. – Milli- always means 1/1000 of a base unit. That means that a milligram is 1/1000 th (fraction) the size of a gram. – Kilo- always means 1000 times the size of the base unit. That means that a kilogram is 1000 times larger (multiple) of a gram. Adding a Prefix to a Base Unit

21. There are way more prefixes than you will ever need to use in your life. However, there are six common prefixes that you do need to know. We can look at these prefixes in the form of a ladder. Adding a Prefix to a Base Unit

22. SI Prefixes Prefix Ladder Kilo – 1,000 k Deka– 10 dk or da Hecto– 100 h Base Unit 1 Liter (L) Meter (m) Gram (g) Deci – 1/10 d Centi – 1/100 c Milli – 1/1000 m Using the symbols for prefixes AND base units, what would the symbol be for a centigram?

23. Think about King Henry… http://www.brainpop.com//science/scientificinquiry/m etricunits/ How do we remember these prefixes!?

24. King Henry Doesn’t Usually Drink Chocolate Milk How do we remember these prefixes!?

25. Lastly… DON’T FORGET TO LABEL YOUR UNITS! 5 doesn’t tell you anything… – It could mean…

27. Numbered Heads/Jigsaw Everyone in your table group will need to number off from 1-4 (it’s okay if there are duplicate numbers in a table group. All the number 1’s will work on box 1 of the guided notes. All the number 2’s will work on box 2 of the guided notes. All the number 3’s will work on box 3 of the guided notes All the number 4’s will work on box 4 of the guided notes. 18 min

28. Numbered Heads/Jigsaw Your job is to identify the best unit for each example measurement. You must choose the correct base unit and prefix. Some of them might just be the base unit with no prefix! 18 min

29. Numbered Heads/Jigsaw After 3 minutes, scholars will get together with other 1’s, 2’s, 3’s, and 4’s from other table groups to compare and discuss answers. When you have agreed on the correct units, you will take your information back to your table group and share for 5 minutes. 18 min

30. Numbered Heads/Jigsaw Silently begin working on your assigned questions. Don’t forget to explain why. Do not work ahead on any other questions in other boxes. You will have 3 minutes to complete your questions. If you need any references of quantities, use the information sheet at each table or the materials at the front of the room. 3 min

31. Numbered Heads/Jigsaw All of the 1’s meet in the front right corner of the room. All the 2’s meet in the back right corner of the room. All of the 3’s meet in the front left corner of the room. All of the 4’s meet in the back left corner of the room. Discuss your units and come up with a consensus about what units to use to measure the quantities. 4 min

32. Numbered Heads/Jigsaw All scholars should go back to their table group. Each scholar will share out for about a minute about the quantities in their box while their group members take notes. By the end, all scholars should have every question filled in. Voice level 1 5 minutes 5 min

34. Independent Practice Silently work on the worksheet over SI Units. Fill in the blank boxes (quantity, unit, symbol) of the top section based on the information already provided to you. Explain the meaning of the prefixes in the bottom table – Ex. Kilo- is 1000 times larger than the base unit. Fill in the blanks at the very bottom of the page. 20 min
