Grade 5 Scientific Investigation Practice Test

Build Grade 5 Science skills with five 10-question practice tests on questions, hypotheses, variables, controls, procedures, data, graphs, conclusions, models, and safety.

Scientific Investigation Practice Tests

These Grade 5 Science practice tests help students plan and evaluate investigations. Students ask testable questions, write hypotheses, identify variables and controls, follow procedures, collect and graph data, draw evidence-based conclusions, use models, and follow safety practices.

Skills covered

  • Writing focused and testable scientific questions
  • Making testable predictions or hypotheses
  • Identifying independent, dependent, and controlled variables
  • Planning fair tests, control groups, and repeated trials
  • Choosing tools, units, tables, and graphs
  • Connecting data to conclusions and recognizing limitations
  • Using models, communicating results, and following safety rules

How to use these practice tests

For each situation, identify what is changed, what is measured, and what is kept the same. Then decide whether the evidence supports the conclusion and whether the procedure is fair, repeatable, safe, and clearly recorded.
