Main Idea and Supporting Details
Learn About It
CH 13 Lesson 1
The main idea of a passage is what it is mostly about. The author’s main idea is his or her
message to the reader about the topic of the passage. Details in the passage, such as
examples or comparisons, explain and support the main idea. Often a writer will state the
main idea, but it also might be implied, or hinted at, throughout the passage.
Read the passage. Look for a main idea statement. Then look for details that
support it.
Size, shape, and state
Suppose you are playing baseball with friends. You hit a homerun right through the
garage window. The glass shatters into hundreds of tiny pieces. Your baseball has caused a
physical change in the window glass. A physical change is a change in the way matter looks
without changing it into a new kind of matter. Many physical changes change the size, shape,
or state of matter. Breaking the window caused a change in the shape and size of the window
glass, but each tiny piece of glass still has the same properties of glass. No new kinds of matter
were formed.

Cause and Effect
Learn About It
CH 13 Lesson 1
When you look for cause and effect in a passage, you try to find out how one thing leads to
another. A cause is why something in the text happens. An effect is the result of that
happening. Words like so, because and since help you identify cause and effect.
Read the passage. Think about cause and effect- what happens and why it
happens.
Physical Changes
The melting of the juice bar looks different from the frozen part. If you could taste the melted part of
the juice bar, you would observe that is tastes the same as the frozen juice bar. The melted juice bar is
not new kind of matter. It has only changed from a solid to a liquid. A change in state is a physical
change. Suppose you hit the window with a hammer. The glass would break into smaller pieces;
however, it would not change into a new kind of matter. Not all matter changes in the same way when
conditions are the same. For example, at 0 degrees Celsius, pure water freezes but slat water does not.
Matter can change in the way it looks without changing into a new kind of matter.
Cause
Effect
Heat is added to the
frozen juice bar.
Cause
Effect
Air is added to a
balloon, making it
bigger.
Cause
Force is applied to a
window, breaking it
and changing its
shape.

Explanatory Writing: Eggs-actly!
Explanatory writing tells how to make something or do something.
Imagine you are a chef making scrambled eggs.
Before you begin writing, list the physical and chemical changes that
will take place as you make the eggs.
Now, write a paragraph explaining the sequence of changes.
Underline the physical changes. Circle the chemical changes.
Eggs-actly!
First, I cracked the eggs and removed the shells. Second, I mixed the
eggs together with a fork. Third, I turned on the stove and__________
