Making Measurements - The Tools and Metric Units

We have been working on Measurement in class.  Measure twice, cut once is out motto!  We learned about linear (length) measurent and how to correctly and accurately use a metric ruler, meter stick, metric tape measure, and a meter wheel.  One activity we did was to blow bubbles on our desk and when they popped, measured the diameter of the footprint they left to the nearest mm.
  In addition, we took a Kiolmeter walk to get an understanding of how long a km is.

We practiced using pan balance scales to determine the mass of various objects.

Now, we are learning how to use a Graduated cyclinder to find the volume of water.
