ENERGY TRANSFER: WAVES, SOUND AND LIGHT
Kit #211

Students produce both longitudinal and transverse mechanical waves and compare their
similarities and differences . As an introduction, they use water and springs to observe
wavelength and frequency . Their exploration of waves continues through investigating
vibrations and the production of sound waves. Using an elasticized string allows them to create
and observe different pitch notes and relate the sounds produced to the frequency of the
vibrations . They then read about the wave nature of different energy forms, including light and
sound, and are introduced to the fundamental features common to all waves .
Accommodates unlimited classes, each with 6 groups of four students.

DENSITY: LAYERS OF LIQUIDS
Kit #114
This activity provides students with experiences that allow them
to develop an operational definition of density. Students are
provided with liquids of different viscosity and density and asked
to observe and predict, based on their observations, the relative
density of each . They then test their predictions and develop an
understanding of density by preparing sequences of liquid layers .
They are given values for the density of each liquid and asked to
use this information to estimate the density of an unknown solid .
Finally, there is an optional challenge to design and carry out an
experiment to determine the density of a fourth liquid .
Accommodates two classes, each with 6 groups of four students.
