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

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

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 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.
