This study was conducted to determine 4th, 5th, and 6th grade primary students‟
conceptions about the particulate nature of matter in daily-life events. Five questions were
asked of students and interviews were used to collect data. The interviews were conducted
with 12 students, four students from each grade, after they finished the formal courses
related to the particulate nature of matter. The results show that the understanding level of
students in all grades about the microscopic properties of matter was quite low. They have
little knowledge of or alternative conceptions about the microscopic properties of the
particles such as the order of the particles, spaces between particles, the number of particles
in different phases, the size of particles and the movement of the particles. And also,
progression of students‟ conceptions on the particulate nature of matter is multifaceted. In
addition, it was also determined that students have trouble connecting science knowledge to
their daily-life experiences.
