Learning Task 4: Read the passage below on chemical and physical changes. Then, compare and contrast chemical changes and physical changes by arranging the information using the graphic organizer below. Identify their differences and similarities. Do this in your notebook.
Chemical and Physical Changes
Any matter can be changed in two ways: chemically and physically. Physical changes do not change the make-up or identity of the matter. For example, clay will bend or flatten if squeezed, but it will still be clay. Molding the clay to change the shape is a physical change, and does not change the matter's identity. Meanwhile, chemical changes turn the matter into a new kind of matter with different properties. For example, a burnt paper becomes ash and will never be turned back to paper again. The difference between them is that physical changes are temporary or only last for a little while chemical changes are permanent, which means they are irreversible. Physical and chemical changes both affect the state of matter.

Answer:
Comparison and Contrast
Comparison statements relate similarities between two things, people, and places. Contrast statements relate differences between two things, people, and places. These are often used in presenting ideas. Readers get the most of the text they are reading thru comparison and contrast style of writing. Examples are characters from books, events in history, foods, arguments, or many other topics.
