Students explore photovoltaic systems. In this alternative energy lesson, students calculate solar panel efficiency and convert devices to solar energy using photovoltaic cells.

Students define sample, describe a random sample, and discuss what compromises a sample. They determine a sample size to estimate a population characteristic with confidence.

Students create and color a one-patch quilt design based upon a regular hexagon. They examine quilts and photos of quilt designs, read a handout, and complete their quilt design on a worksheet.

Students recognize patterns and sequences in numbers. In this geometry lesson, students create rules to define the sequences and patterns they obsere. They translate coded messages as they dicuss navigational terms.
