Title: Measurement Lab

Purpose: To hone your measurements skills using various scientific instruments.

Table 1: Measurement of Various Objects Using the Metric System.

Mass of two full containers

Mass of 1 empty container

Mass of powder only (CuSO4)(do not pour it out; use a calculator)

Volume of H2O in graduated cylinder

Volume of H2O in Erlenmeyer flask

Mass of metal rod

Width (distance) of tabletop

Width (distance) of piece of paper

Temperature of room

Conclusion Questions: Metric to Metric conversions

1. 1) Convert the number of grams of blue powder to mg

2) Convert the volume of H2O in the Erlenmeyer flask to liters (L).

3) Convert the width of the table to kilometers.
