On the scaled outline, brainstorm with your partner(s) about the location, relative size, and shape of the following organs of the human body: lungs, heart, liver, stomach, intestines, and kidneys. On the scaled outline, brainstorm with your partner(s) about the location, relative size, and shape of the following organs of the human body: lungs, heart, liver, stomach, intestines, and kidneys. Using separate pieces of paper, sketch the organs to actual size, cut them out, and place them on the appropriate locations on the outline on the large piece of paper.
