• Grade 3 Description

    In this grade level, students investigate and explore through four units of study.  During each unit, students practice and apply science process skills with a particular emphasis on on making observations, communicating, comparing and organizing objects using physical properties.

    Grade 3 Earth Science students focus on Earth Materials and Systems. In this unit, students will engage in scientific inquiry through which they will discover that earth materials have distinctive physical and chemical properties.  The concepts explored include: rock formation, rocks as aggregates of minerals,  distinctive properties of minerals identifiable through testing, mineral composition,  and use of rocks and minerals as determined by their properties.


    Grade 3 Physical Science students focus on Wave Properties. In this unit, students learn to discriminate between sounds generated by dropped objects, how sounds can be made louder or softer and higher or lower, how sounds travel through a variety of materials, and how sounds get from a source to a receiver.  The investigations provide opportunites for students to explore the natural and human-made worlds by observing and manipulating materials in focused settings using simple tools.  Students are expected to use scientific thinking processes to conduct investigations and build explanations through observing, communicating, comparing, and organizing.


    Grade 3 Life Science students focus on Plant Life Cycles. In this unit, students engage in scientific inquiry utilizing Brassica rapa, the Wisconsin Fast Plant. They explore the concept that plants go through distinct stages that are part of a life cycle.  After planting seeds, students observe and record the first stages of growth.  Using a bee stick to simulate the actions of a bee, students gain an understanding of pollination and its role in fertilization.  They explore the relationship between form and function as they construct models of a Brassica plant and of a bee.

    Grade 3 Life Science students focus on the Sun. In this unit, which accompanies the Plant Life Cycle studies, students learn about the forms of energy that come from the sun and how it effects, and is necessary for, all life on earth.
