The student uses scientific methods during fieldwork and laboratory investigations. The student uses critical thinking and scientific problem solving to make informed decisions. The student knows how to use a variety of tools and methods to conduct science inquiry. The student knows the relationship between structure and function in living systems. Students use pulleys and levers to understand the relationship between force and motion.
Students then relate the concept to processes in the human organism such as the movement of blood.
In addition, Grade 7 students study chemical and physical properties of substances, examine the tarnishing of metal or burning of wood as example of chemical processes, and identify physical properties used to place elements on the periodic table. Students learn about kinetic and potential energy and identify photosynthesis as an example of the transformation of radiant energy from the sun into chemical energy for use by plants. Students investigate living systems in humans to identify the structures and functions of those systems. Students compare asexual and sexual reproduction to illustrate that genetic materials are responsible for both dominant and recessive traits in organisms. Science is a way of learning about the natural world.
