Description
This set of instructional material is a combination of games andpuzzles intended to help students review, distinguish and analyze thedifferent characteristics of living things.
They are also guided on how to classify or group these diverseforms of living organisms through their structural characteristics.
Students are also aided to distinguish the various economicimportance of the different groups of living organisms.
Target Audience
Second Year Science and Technology (Biology) Students
Subject Matter/Learning Competencies

Duration
Three (3) sessions at sixty (60) minutes each

Objectives
• Review and analyze characteristics of living and nonlivingthings
• Classify objects either as living things or nonliving• Distinguish some common physical characteristics of
plants and animals• Identify certain characteristics of plants and
animals through a crossword puzzle• Distinguish animals with backbones from those
without backbones• Classify vertebrates and invertebrates on the basis
of their structural characteristics• Appreciate the economic value of some vertebrates
and invertebrates
Procedure
• Divide the class into smaller groups of at least threeto four members per group to maximize studentparticipation and to avoid monopoly of the games.
• Answers to each game card should be written on it.• Encourage discussion of answers among members in
each group.• Answers should be discussed or processed by the
teacher and the whole group after each activity orwhen the game is over.
• Strictly follow the time limit allowed for every gameor activity.
Teaching Hints
• Game Card Nos. 1 and 2 can be given as motivationto allow students to recall prior knowledge then relatethem to the present topic in the activities.
4
• Assignment about the characteristics of plantsand animals and also on vertebrates and invertebratesshould have been given before undertaking the
activities or the game cards.• Allow heterogeneous grouping so that the slow and fast
learners can be equally distributed.
The teacher has the option to:
• take up the series of activities in a single session bygiving different sets of games to different groups thenrequire them to exchange game cards
• allow the whole group to go through the series ofactivities within the duration prescribed
• reproduce each set of game cards according to thenumber of members per group for maximum studentparticipation
• use the Game Cards for evaluation purposes.
Evaluation
The success of this material can be measured by:
• completion of the game cards within the specifiedperiod of time
• maximum participation of every member in the groupduring group discussion
• attainment of 80% or more performance level in everyactivity/evaluation for each game card.

LIVING THINGS BOTH
It can move by itself.
LIVING THINGS
6

Answer Key (Cont’d)
Procedure B
can produce wasteas a result of self-activities
needs energy inorder to move
can move eitherslowly or fastby itself
7
Procedure C
1. No. Bottles are not living things because their growth doesnot come from within themselves. They do not reproduce bytheir own will but are produced/manufactured by man.
2. No. Cars are not living things. Their “perspiration” andfeelings of being “hot” or “cold” are not felt by them but bythe persons checking on them.
3. Yes. Remains of living things who were formerly alive likeseashells or other fossils are considered living things ororganic. Parts of plants like lumber and wood are alsoconsidered as living things.
4. No. Rocks are not living things because its motion is notdone by its own will, but is influenced by other outsidefactors like gravity or manual force.
5. Yes. Fruit trees are living things because they can reproducetheir own kind by themselves.
We can say that an object is a living thing when it can
1. move by itself.
2. grow from within.
3. exhibit metabolism like respiration, undergo digestion, reactappropriately when exposed to a stimulus and excrete orproduce waste materials after an activity is done.
4. reproduce its own kind.
5. respond to stimulus.

1. A can react to changes around them more quickly2. P have branching bodies3. P mostly stay in one place4. A can move about from place to place by their
ownselves5. A mostly have compact bodies6. A do not have chlorophyll7. P can make their own food8. A depend on others for food9. P have chlorophyll10. P can react to changes around them but slowly
