Mass, Volume, & Density

Today, we explored mass, volume, & density.  We first watched a video to help explain the difference between mass & weight.  Then, we used balance scales, rulers, and magnifying glasses to observe and measure physical properties of rectangular prisms.  By measuring the volume and mass, we were able to calculate the density of the three prisms.  Each lab group created a hypothesis as to whether they believed the prisms would have the same or different masses/densities as they had very similar volumes.

To extend this activity, we then used irregularly shaped items instead of rectangular prisms.  We compared cherries and raspberries.  In order to determine volume, we learned to use water displacement in graduated cylinders.
