Understand Why Things Happen: Cause, Effect & Evidence Vocabulary for Class 7 

This Grade 7 worksheet focuses on academic vocabulary related to cause, effect, and evidence—core concepts that help students explain why something happens, what results from it, and how ideas are supported. Learners work with connectors like “because,” “therefore,” “due to,” and “as a result” to build logical relationships between ideas and strengthen their reasoning skills.

 

Why Cause, Effect & Evidence Matter in Grammar? 

This topic is not just about vocabulary—it’s about logical thinking and clarity in expression. For Grade 7 learners, this is important because: 
1. It helps students understand relationships between actions and outcomes. 
2. It improves structured writing using logical connectors. 
3. It builds the ability to support ideas with evidence. 
4. It strengthens reasoning in both academic and real-life contexts.

MCQs test understanding of correct connectors and their usage in forming logical sentences (pages 6–7).

🔁 Exercise 5 – Sentence Rewriting 
Students replace incorrect connectors (like “although”) with correct cause-effect connectors such as “because” or “therefore” to fix logical errors (page 8).
