Science 4 Quarter 1 – Module 2: “Changes in Solid Materials”

This module was designed and written to help you understand that matter undergo different changes. Such changes are physical changes if the objects only change in size and shape and no new material was formed from the change. In this lesson you will be dealing with the physical changes that happens to solid materials in terms of their sizes and shapes.

The lesson focuses on:

• Lesson 1 – Changes in solid materials when bent;

• Lesson 2 – Describe changes in solid materials when they are pressed;

• Lesson 3 – Changes in solid materials when hammered; and

• Lesson 4 – Changes in solid materials when cut. (S4MT-Ie-f5)

After going through this module, you are expected to:

• identify characteristics of solid materials in terms of size, shape, texture;

• describe what happens to the solid materials when they are bent;

• identify some changes happened to solid materials when pressed;

• describe the change/s that happen/s in solid materials when pressed;

• identify some ways of changing solid materials in terms of size, shape, texture by hammering;

• identify materials which can be cut;

• describe the change/s that happen/s in solid materials when hammered; and

• describe what happens to solids when cut.
