This study aimed to investigate (i) the relationship between pupils' learning styles and their performance in mini science projects and (ii) the degree of enjoyment of pupils with different learning styles towards mini projects. A total of 80 pupils (7th grade-14 years of age) from two different primary schools participated in the study. The Grasha-Riechmann Learning Style Scale was used to determine the pupils' learning styles. Results showed that all categories of pupils except avoidant were stimulated to varying degrees by the mini projects. However, the pupils who were in the "independent," "competitive," and "participant" groups had relatively higher achievement scores in the mini projects than the pupils in the "avoidant," "dependent," and "collaborative" groups. Similar results also appeared for the degree of enjoyment. The implications of the results for teaching and learning science are discussed. (Contains 5 tables.)
