The shape of a molecule is determined by the arrangement of atoms around the central atom and lone pairs of electrons. Scholars build models of molecules using single, double, and triple bonds. They can then see real molecules bond...

Students investigate circles and spheres. For this space shapes lesson, students compare and contrast two-dimensional and three-dimensional shapes. Students investigate the relationship between plane and space shapes.

Students explore lines of symmetry. In this symmetry lesson, students divide and combine shapes along basic lines of symmetry. Students explore symmetry in real life objects.

Students discuss reasons to record the location of stars. They view a picture of the night sky, and discuss constellations. Students complete a worksheet of the various shapes they see in the constellations.

Students explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...
