Class 7 Science Worksheet: Understanding the Changes Around Us

Description

A six-page Class 7 Science set on physical and chemical changes. Page one has ten multiple choice questions on melting ice, burning wood, rusting iron, cooking food, dissolving sugar, freezing water, evaporation, condensation and crystallisation, with the answer printed under each question.

The last page is an Assertion and Reason worksheet of eight pairs. The child reads an assertion such as Melting of ice is a physical change and a reason such as only the state of water changes, then picks whether both are true and the reason explains the assertion, with the answer given under each pair.

Every page carries its own answer key, so correcting the sheet takes only a few minutes.
