Instructional Ideas

• Use the worksheet as a formative assessment instrument

Classroom Considerations

• Learners should have some familiarity with the science contexts in the questions; preview worksheet to see if it is appropriate for your pupils
• You may need to have your class disregard some of the test-taking directions depending on how you use the resource

Pros

• Includes variety of contexts

Cons

• Does not distinguish between weight and mass
• Science questions are not entirely accurate; uses incorrect acceleration due to gravity, for example
