Modeling and volume, with precision and accuracy

Activity to investigate the relationship between cubic centimeters and milliliters.  Students carefully (or not so carefully) calculate the base area for their container, fill it to various heights (depths) of water, and measure the volume of water in the container.

"You can do it!  I've … Continue reading My first quarter with the “Interactive Notebook”
