Assertion Reason Questions for Class 8 Science

Assertion Reason questions are a type of question often used in science exams that ask the test taker to evaluate a given statement (the assertion) and provide a reason that supports or contradicts that statement.

In this type of question, the assertion is typically a statement about a scientific concept or phenomenon, and the reason is a statement that provides evidence or justification for the assertion. The test taker is usually asked to evaluate the assertion and reason and determine whether the reason is a valid justification for the assertion.

For example, an assertion might be “Plants produce oxygen during photosynthesis,” and the reason might be “During photosynthesis, plants use energy from the sun to convert carbon dioxide and water into glucose and oxygen.” The test taker would need to evaluate whether the reason provides a valid explanation for the assertion.

Best Approach to Answers Assertion Reason Questions for Class 8 Science

Here are some tips for approaching Assertion-Reason questions:

1. Understand the meaning of the terms: Before answering an Assertion-Reason question, make sure you understand the meaning of the terms used in the statements. This will help you evaluate the truthfulness of the statements and understand the relationship between the assertion and the reason.
2. Evaluate the Assertion: Read the assertion carefully and determine whether it is true or false. If you find that the assertion is false, then the reason is automatically false, and you can eliminate answer choices that claim otherwise.
3. Evaluate the Reason: After evaluating the assertion, evaluate the reason. Determine whether the reason explains the assertion. If it does not, then the answer is false. If it does, then you need to check if the assertion is also true.
4. Combine the answers: After evaluating the assertion and reason individually, combine the answers. If both the assertion and reason are true, and the reason explains the assertion, then the answer is true. If any of the above is false, the answer is false.
5. Eliminate extreme answers: If you are not sure about the answer, try to eliminate extreme answer choices. For example, if the assertion is true, and the reason is false, eliminate answer choices that claim both are true or both are false.
6. Don’t assume additional information: Do not assume additional information that is not given in the statements. Only evaluate the assertion and reason based on the information given in the question.
7. Practice with past papers: The best way to prepare for Assertion-Reason questions is to practice with past papers. This will help you familiarize yourself with the type of questions and develop a strategy for answering them.
