Objectives:
• To know how to use the different measuring devices properly.
• To know how to solve the volume.
• To know how to solve the Density.
Introduction:
"Accurate measurement is essential" – Measurement is the size, length, or amount of something, as established by measuring. Measurement is the first step that leads to control and eventually to improvement. If you can’t measure something, you can’t understand it. If you can’t understand it, you can’t control it. If you can’t control it, you can’t improve it.
Methodology:
Materials:
• Meter stick
• Ruler
• Vernier Caliper
• Micrometer
• Triple Beam Balance
• Graduated Cylinder
• Short Bond Paper
• Ballpen
• Prism
• Dice
• Eraser of Mechanical Pencil
• Water
Procedure:
• Prepare all the materials needed.
• Be sure that you know how to use the apparatuses if not, ask the teacher or facilitator.
• Measure the things that you chose to measure, be sure that you measured it accurately.
• Record all the data that you have gathered.
• Create an SDA about the different measurement devices that you use.
Data/Observations:
a.) Meter stick –57.5 inches – Suzzaine’s Height –58.5 inches – Physics Lab Table
b.) Ruler – 15.8 cm – Micrometer Case
c.) Vernier Caliper – 12.5 cm – Prism
d.) Micrometer – 33 mm – Eraser of a mechanical Pencil
e.) Triple Beam Balance – 158.4 g – Dice – 230 g – Prism
f.) Volume – 262.5
g.) Density – 2.3 g/mL
Calculations/Analysis:
Volume:
Width – 6 cm
Height – 3.5 cm
Length – 12.5 cm
L*W*H
(6 cm)(3.5cm)(12.5cm) = 262.5
Density:
Mass/Volume
262.5 / 158.4 = 1.7 g/mL
Questions:
• Which is more accurate, the micrometer or Vernier Caliper?
• What is the most accurate measuring device?
• What is the least accurate measuring device?
Conclusion: I therefore conclude that not all measuring devices have the same level of accuracy.
