Observe light from a variety of sources. |
And wonder and discuss why they are seeing colorful spectra. |
They learn that various light sources give off slightly
different spectra and that the glasses are made from diffraction
gratings that break up white light into the colors of the
rainbow. In this investigation, like all investigations,
participants use science process skills like observation,
measurement, and prediction and learn science content like the
characteristics of light. Teachers like those in Trieste and
Udine are encouraged, via the models presented, to use similar
inquiry techniques in their own classrooms. |
Carla Beltramini, science teacher leader, and Trieste and Udine
Director Peter Metzger, receive prizes for their leadership and
cooperation in hosting the site visit. |
In this next series of photos, Dr. Harry introduces herself to
parents at the International School of Egypt in Cairo and
presents an overview on inquiry in science. She will have the
parents investigate sound. |
Here parents investigate the effects of a vibrating tuning fork
placed in a cup of water. |
Now they investigate vibrations in a soda straw, being
challenged to make sounds with their straws. |
Cairo parents continue investigating variations in pitch by
changing the lengths of their straws...an obvious fun
experience. |
Finally, parents investigate sounds from vibrating "talking"
cups. Parents learned about sound and vibration, pitch, and
amplitude. They also learned inquiry processes including
prediction, observation, and inferring. Most importantly they
experienced what inquiry science was like through first-hand
experiences, the kinds of experiences their own children
participate in during science classes in school. |
