5th Grade Science Practice — Iowa Assessments (ITBS) Prep

This 5th Grade science practice set covers the scientific reasoning and content knowledge assessed on the Iowa Assessments (ITBS). Students will answer questions spanning life science, earth and space science, and physical science, while also demonstrating scientific inquiry skills such as forming hypotheses, interpreting data, and drawing conclusions from experiments. The science section of the Iowa Test of Basic Skills evaluates students' understanding of key scientific concepts and their ability to think like scientists. These practice questions help students prepare for the types of science items they will encounter on the actual assessment while building broad scientific literacy.
