In this study, we discuss the scaffolded design of ODRES, a computer tool that was designed to be used with elementary school children in science. Succinctly, the software engages learners in inquiry learning to solve a mistery problem about a stolen diamond. ODRES scaffolds students' investigations with different tools such as the simulator, which simulates the effects of the colour of a light source on an object, a magnifying glass, which enables students to make careful observations, and the notebook, which organizes the results of students' investigations. Herein, we report on the effects of learning with ODRES as well as the effects of ODRES on students' understandings about light and colour. The results showed that the effects of the intellectual partnership with ODRES as well as the cognitive residue that ODRES left on learners were significant.
