Measurement Review What do you remember?

Measurement Write the title :Measurement Tools and Units at the top of the page then divide the page into four equal parts, neatly. Measurement Tools and Units

Draw and name each of the following: Graduated CylinderBeaker Thermometer Scale Ruler

Measurement Tools and Units Next to each of your pictures, write the UNITS and MEASUREMENT OF__ that are used by each tool… So, a ruler measures in millimeters, centimeters, decimeters, meters, and so forth. All these are meters. Next to the ruler write: Units = meters (m). Measurement of distance.

Measurement Tools and Units Beakers and graduated cylinders measure in units called… liters Write: Units = liters (L) Measurement of volume.

Measurement Tools and Units Thermometers measure in units called… degrees Write Units = degrees Celsius or Fahrenheit or Kelvin (‘C, ‘F, K) Measurement of temperature.

Measurement Tools and Units Scales measure in units called… grams Write Units = grams (g) Measurement of mass.

Measurement Tools and Units Your final chart should look similar to: Graduated CylinderBeaker Thermometer Scale Ruler Units = meters (m). Measurement of distance Units = liters (L). Measurement of volume Units = degrees (‘C, ‘F, K). Measurement of temperature Units = grams (g). Measurement of mass

Measurement Good job so far!

Measurement Make 7 columns on a new page in your journal. We are going to learn a saying to help us remember the order of the prefixes.

Measurement The saying is “King Henry Dances Merrily Down Central Main” Write the saying across the top of the columns: KingHenryDancesMerrilyDown Central Main

Measurement Now for the trickier part. Draw a second horizontal line and leave that row blank for now. Recall we can measure in meters, liters, grams, and degrees. Except for degrees, let’s add that to our chart. First, add 3 more horizontal lines. KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g)

Measurement Not so bad… Okay, each word in the saying stands for another measurement term. King = kilo (k). Add it to the chart. Can you think of any others? KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g) kilo (k)

Measurement The rest are as follows: Henry = hecto (h) Dances = deca (da) Merrily = m or L or g Down – deci (d) Central = centi (c) Main = milli (m) KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g) kilo (k)hecto (h)m, L, gdeca (da)deci (d)centi (c)milli (m)

Measurement Now that you know all the abbreviations, we can fill in the blanks. It is kind of like a puzzle. The first empty box would be a kilo + meter or kilometer (km). This is a measurement that is 1000 times bigger than a meter! KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g) kilo (k)hecto (h)m, L, gdeca (da)deci (d)centi (c)milli (m) km

Measurement Now add the rest of the boxes. This will take awhile the first time but soon you should be able to do this in less than 30 seconds! KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g) kilo (k)hecto (h)m, L, gdeca (da)deci (d)centi (c)milli (m) mm hmkm dm cmdam kLhL daL dLcLmL kg mgcgdg dag hg

Measurement Yay! Okay see if you can find the decigram by pointing to it. The centiliter? The hectometer? The decameter? KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g) kilo (k)hecto (h)m, L, gdeca (da)deci (d)centi (c)milli (m) mm hmkm dm cmdam kLhL daL dLcLmL kg mgcgdg dag hg

Measurement Alright. Now recall that these measurements are NOT all the same size. They are actually all related though because they are all powers of 10! If a m is 1, then a dam is 10x bigger! And a hm is 10x bigger than a dam or 10 x 10 (100x) times bigger than a m! KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g) kilo (k)hecto (h)m, L, gdeca (da)deci (d)centi (c)milli (m) mm hmkm dm cmdam kLhL daL dLcLmL kg mgcgdg dag hg

Measurement A km would be 10 x 10 x 10 or 1000 times bigger than a m. A dm would be 10x smaller than a m or 1/10 =.1 A cm is 10 x 10 or 100x smaller than a m so this is 1/100=.01 And a mm is 10 x 10 x 10 or 1000 times smaller than a m so 1/1000 =.001 KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g) kilo (k)hecto (h)m, L, gdeca (da)deci (d)centi (c)milli (m) mm hmkm dm cmdam kLhL daL dLcLmL kg mgcgdg dag hg

Measurement Lets add some terms around our completed chart. KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g) kilo (k)hecto (h)m, L, gdeca (da)deci (d)centi (c)milli (m) mm hmkm dm cmdam kLhL daL dLcLmL kg mgcgdg dag hg larger smaller Increases by 10’sDecreases by 10’s

Measurement We’ll use this chart to convert… But at a later time KingHenryDancesMerrilyDown Central Main meters (m) liters (L) grams (g) kilo (k)hecto (h)m, L, gdeca (da)deci (d)centi (c)milli (m) mm hmkm dm cmdam kLhL daL dLcLmL kg mgcgdg dag hg larger smaller Increases by 10’sDecreases by 10’s

Measurement You are almost ready to move on to planning your own creation. But first, let’s look at the measurement tools up close to make sure you remember how to use them. And don’t forget, you should always ASK for help before touching something you do not understand, especially if you are worried about breaking it.

The Ruler - distance Most commonly on the ruler, you will measure in cm. These are visible in the picture here and they are about the width of your pinky. This side is inches. We DO NOT USE THESE. Between each cm is 10 mm. They are he tiny lines about the thickness of your nail.

The Ruler - distance Can you name the item we said was about a… mm... cm… dm… m... dam... hm… km…

The Beaker and Graduated Cylinder - volume Recall that we use the beaker for less precise measurements and the graduated cylinder for more exact measurements because it measures in smaller increments.

The Beaker and Graduated Cylinder - volume Also, we always use the ___________ to fill up the ____________________. Notice these measure in mL. On the graduated cylinder look at the bottom of the curve called the ___________. beaker graduated cylinder meniscus

Scale - mass This particular scale measures in g.

Thermometer - degrees You’ll see that the classroom thermometer measures in ‘C and ‘F. We will most commonly talk about ‘C.

The End For Now
