start off the year with a quick overview on observation, drawing, and
recording. These skills will be worked on throughout the year. We will
also focus on science discussion, science journals and science
The fourth grade will start the year with our unit on Our Changing
Earth which includes the basics of Earth Science. We will take a brief
look at the structure of the Earth and then focus on the crust and what
happens to the crust. Changes happen quickly, as in earthquakes, or
slowly, as in weathering and erosion, and students will investigate how
this works using stream tables, soils, rocks and sand. A field trip to
the Maynard Ecology Center will show them what happens at Fresh Pond
when soils erode and weathers.
During the winter term, we will study electricity using a unit called
Circuits and Pathways. Students will build circuits, learn about safety
concerns and investigate the wonderful world of electricity. We plan to
take a field trip to the MIT Edgerton Center during this unit where
students build quiz boards or flashlights.
Springtime will bring us to a unit about the Solar System. We will
look at the components of the solar system, the relative size and
distances between the planets, cycles such as the seasons (and why we
have them), and the phases of the moon. Concepts that we focus on
include cycles, systems, light and shadow.
Our goal is to show the students some of the wonders, help them to
know that their ideas and their questions are valid and wonderful and
that they have potential to be the future scientists of the world.
