In this study, multiple intelligences (MI) of sixth grade students were investigated to determine the extent to which they affect the students' achievement on the topic of the particle model of matter. The study was conducted with four randomly selected elementary schools with a total 132 sixth grade students in the Spring 2008 semester. Pearson correlations and ANOVA tests results revealed that there were positive low correlations between achievement and mathematical-logical, visual-spatial, and interpersonal intelligences. Also, it was found out that bodily-kinesthetic learners' achievement level were lower than mathematical-logical, visual-spatial, and musical learners. Similarly, naturalistic learners' scores were lower than the mathematical-logical and visual-spatial learners. (C) 2010 Elsevier Ltd. All rights reserved.
