We have been measuring objects using scales!
We were checking to see which objects are heavier and which are lighter. Today we measured the mass of the objects to find out exactly how heavy the objects are! We chose cubes to give us a more exact measurement of the weight of each object. The unit of measurement must stay the same if we compare the weight of objects.
Key Questions:
Which object do you think is heavier/lighter?
Is a _____________ heavier or lighter than a ____________?
How can you show which object is heavier/lighter?
Are large objects always heavier than small objects?
How do you know?
How does the balance scale show which object is heavier?
If two objects are the same size and shape, does that mean
that they have the same mass? How do you know?
