This paper lists 35 studies in biology which can be tailored to suit the full range of student age groups and are designed to involve most or all of the key elements of the scientific process (study design, data collection and presentation, and experimental manipulation). Examples of some studies are: (1) study the growth of molds on food items under different growing conditions; vary foods and growing conditions; (2) study absenteeism in school; relate to colds, flu, other illnesses; (3) visit a local pond where bats forage at dusk; time of arrival of the bats on different nights and compare with time of year; estimate insect abundance by counting sudden changes of flight direction; and (4) conduct a behavioral study of your companion animal(s) at home: e.g., to what sounds do they respond; compare response to different vocal inflections; examine play behavior, etc. (MKR)
