In the first step, an achievement test of 26 questions was created by referring to the opinions of two science experts and a science teacher, and the test was piloted. As a result of the applications, the test was finalized with 17 questions. Good fit values of the final test were determined as χ2 / df: 2.097, RMSEA: 0.0059, GFI: 0.937, AGFI: 0.928 and CFI: 0.966. The factor loadings of the questions vary between 0.340 and 0.719. The KR-20 internal consistency coefficient of the test was 0.785, the average item difficulty index was 0.471, and the average item discrimination index was 0.562.
