Classifying involves arranging objects or information into groups based on common characteristics. It involves carefully observing objects to identify similarities and differences, choosing a characteristic to use for grouping, and potentially further dividing groups based on additional characteristics. Classifying can be done by observation alone or with the use of a table to list characteristics of different groups. The goal is to organize information or objects systematically according to their attributes.

1. Classifying
Classifying is when you arrange
or sort objects by following
a certain rule or order.

2. Classifying objects or information:
1. Carefully observe the objects that you will classify. Identify their
similarities and differences.
2. Choose a characteristics that is common to most of the objects.
Use this characteristic as your guide to regroup the objects.
3. Look closely to the smaller groups that you form. See if there are
other characteristics that you can use to reclassify the objects and
then repeat the first two steps.
Classifying is arranging a set of objects or information by
following a certain order.
Characteristic is a distinct feature or trait of a person or object.

3. 4. Another way of classifying is by using a table. A table helps you
list the similarities and differences between objects.

4. Classifying is grouping objects or information according
to their common characteristics.
Sorting and using a table are some of the ways that you
can classify objects or information.

5. Measuring
Measuring is science process
skill that helps you know the length,
mass, volume, area, temperature,
and other characteristics of an object.

6. Standard units of measurement
and
Nonstandard units of measurement

7. Standard units of measurement are those that are
commonly used for measurements.
Common Standard Units
property basic unit symbol
length meter m
mass gram g
liquid volume liter L
temperature degree Celsius ◦C

8. Nonstandard units of measurement are those that are not
commonly used. They can only be described according to how
many objects are used for measurement.

9. Predicting
Predicting is a science process skill by
which you tell what is likely to happen
based on what you know
and observe.
