    Fall Unit: Sound

    Students become more aware of the nature of sound and of the diversity and abundance of sounds around them. They begin by listening to sounds on tape. They then make their own sounds with their bodies, with drums, and with other instruments-exploring vibration, pitch and volume, and the transmission of sounds. Throughout the module, students compare the qualitative characteristics of the sounds they hear.

    Winter Unit: Chemical Tests

    This unit introduces third-graders to the science of chemistry by challenging them to explore and determine the identity of five common household chemicals: sugar, alum, talc, baking soda, and cornstarch. Students begin by focusing on the physical properties of color, form, and texture. Next, they explore chemical properties by observing how the five powders interact with water, vinegar, iodine, and red cabbage juice. These tests enable them to explore phenomena such as crystallization and to observe the processes of evaporation and filtration. Finally, students apply their skills and their knowledge of the five chemicals to identify a variety of mystery mixtures. Because of conducting these investigations, students develop scientific skills such as observing, predicting, recording results, forming conclusions and communicating results.

    Spring Unit: Structures of Life

    As students grow seeds in a hydroponics garden and observe crayfish and snails, they have the opportunity to learn about environmental and living systems. Students identify structures of plants and animals and make comparisons of the organisms based on observable structures and behaviors.
