Science Curriculum – Grade 7

The seventh-grade curriculum includes an integrated approach to science and incorporates a balanced curriculum that provides students with an inquiry approach to learning both living and physical sciences.

Students in the seventh grade develop science skills through inquiry. In the area of physical science. Students investigate physical properties of matter including density, solubility, magnetism, and phases.  Students are introduced to the basic principles of chemistry and forces. 

The ecology portion of seventh-grade deals with the physical environment—water and air. Within this there is an investigation of humidity, clouds and the atmosphere. In the study of weather, students study pressure, wind, fronts, air masses and patterns in  the atmosphere.. 

Students also study the interrelationships in the ecosystem, symbiosis, food webs, energy change and various cycles
