Mystery Matter! October 31 - November 22, 2011

Lab coats and safety goggles were needed for this science unit about matter and its physical and chemical properties. Students were given five unidentified mystery substances, and by learning and using the scientific process of experimentation, they were able to observe many of the properties and behaviors. With each different experiment, students saw how the substances behaved and carefully kept records of what they discovered.

After many sessions, the class narrowed down the possibilities for each substance and made their hypotheses about the identities. Finally, the unknown substances were revealed. The final test of what was learned (content and process) then came when each child was given a secret mixture of at least two of the substances. On their own, each had to perform whatever experiment he or she thought appropriate to identify the ingredients.

Tha Art and Science of Birds October 3 - 29, 2011

Our art teacher, Mrs. Christie, and I collaborated to teach this unit about the scientific wonder and artistic beauty of birds. Students learned about the adaptations, habitats, and behaviors of many different birds.



They were introduced to the prehistoric pteradon (a flying mammal) and to archaeopteryx (a reptile-bird transition species). By researching certain facts about a modern bird, each student was able to write a brief report on one bird of their choice. They also painted beautiful watercolor renditions of their birds and created beautiful bird journals. When the class went outside to do some birdwatching and to practice using their binoculars, they spotted a downy woodpecker, chickadees, crows, and a vulture.










At the end of the unit, everyone was able to take home their own handmade ceramic bird bath/feeder to hang up. Many thanks to Maine Audubon Society in Falmouth for the loan of several mounted birds for the classroom.






Here are a few of the bird posters that now hang near the front office as you enter the school,






These are some of the beautiful bird journals that students created with Mrs. Christie.

The Science of Toys September 7 - 29, 2011

Using everyday toys and toys that they created themselves, students in this first unit of the year got to play with toys and learn important science principles of motion, force, energy, and pressure. Toys such as the Flip-a-Frog, the Ball-and-Cup, cardboard airplanes, and Cartesian divers were assembled and observed closely to understand what forces in nature make them behave the way they do.












A toy that the children built called the Whimmy Diddle, a wooden stick with notches filed into it with a propeller on one end that gets rubbed firmly with another stick, was a striking example of friction and its uses. Newton's three laws of motion were discussed and observed directly with each new toy the class investigated.



Based on what they learned from these experiences with toys on earth, students then predicted how they thought the toys would behave in outer space! All predictions were then checked when the class viewed a video taken by NASA astronauts within the space station. Do you know how a spinning top would behave in space? Do magnetic balls act the same in space as on Earth? What about a bouncing ball? Ask the students from this class!
