They discover that their arm spans are closely equivalent to the
their heights.
More arm span measurements.
Here, wrist circumferences are measured.
Leg length will be compared to trunk height. Discussions will
focus on student understanding of process skills and human body
proportions.
Next, teachers investigate the properties of water. Here a
teacher investigates a water "tornado" in a bottle. What makes
it turn the direction it does?
These teachers are investigating what happens when an inverted
tumbler is placed in water and water does not fill it. They
infer why.
Teachers design and do their own experiments with water. They
learn that inquiry is a way of finding out...a way to ask
questions and seek answers...a way to learn that they can
encourage among their students.
In this investigation, teachers investigate "Rainbow" glasses.
