 3. Put your hands on your chest. How do you feel? Why is your chest beating faster? GUIDE CARD
 4. The human heart is a specialized, four- chambered muscle that maintains the blood flow in the
circulatory system. It lies immediately behind the sternum, or the breastbone, and between the
lungs. The apex, or bottom of the heart, is tilted to the left side. At rest, the heart pumps about 59 cc
(2 oz) of blood per beat and 5 l (5 qt) per minute. During exercise it pumps 120- 220 cc (4-7.3 oz) of
blood per beat and 20-30 l (21-32 qt) per minute. The adult human heart is about the size of a fist
and weighs about 250-350 gm (9 oz). GUIDE CARD
 5. GUIDE CARD The human heart has four chambers, two superior atria and two inferior ventricles.
The atria are the receiving chambers and the ventricles are the discharging chambers. During each
cardiac cycle, the atria contract first, forcing blood that has entered them into their respective
ventricles, then the ventricles contract, forcing blood out of the heart. The pathway of the blood
consists of a pulmonary circuit and a systemic circuit[10] which function simultaneously.
Deoxygenated blood from the body flows via the vena cava into the right atrium, which pumps it
through the tricuspid valve into the right ventricle, whose subsequent contraction forces it out
through the pulmonary valve into thepulmonary arteries leading to the lungs. Meanwhile, oxygenated
blood returns from the lungs through the pulmonary veins into the left atrium, which pumps it through
the mitral valve into the left ventricle, whose subsequent strong contraction forces it out thro ugh the
aortic valve to the aorta leading to the systemic circulation.[
 6. HEART BLOOD BLOOD VESSELS The circulatory system is made up of the heart, the blood and
the blood vessels that transport needed materials and eliminates waste. GUIDE CARD
 7. Major Parts of the Circulatory System What is it like How it works 1. heart It is a heart -shaped
organ. It is made-up of muscles. The heart pumps blood. 2. Blood Red fluid inside the body. The
blood brings materials to the different parts of the body. 3.blood vessels They are tubes where blood
passes. (They are the tubes that serve as the passageway of the blood.) GUIDE CARD
 8. CIRCULATORY SYSTEM WORD FIND ACTIVITY CARD #1 In this activity: You need to find as
many words in the puzzle.
 9. CIRCULATORY SYSTEM BINGO ACTIVITY CARD #2 In this activity: You need to make a
pattern ,it can be a line, either vertical, horizontal or diagonal. The winner is determined when the
player completed the winning bingo pattern which states a brief description of each word.

simulate the flow of blood inside our body through a relay. Materials •5 inflated red balloons •5
inflated blue balloons •poster or drawing of the lungs •playground chalk or mas king tape
 11. Fitness & Recovery Rates ACTIVITY CARD #2 In this activity: You will investigate how fast your
recovery rate and compare it with your classmates Materials •Stopwatch •Wooden stepping block or
stairs about 30cm high What to do: 1. Ask your par tner to count the number of times your heart
beats in 30 seconds. This will be your “resting rate”. Record this in your table. 2. Let your partner
count the number of times you breathe in 30 seconds. Again, record this date on the table. 3. Do

2. step-ups in 3 minutes Ask your partner to time this activity. 4. As soon as the 3-minute exercise is
over, let your partner get your pulse rate in 30 seconds. Mentally take note of the number of breaths
you make in the same 30-second interval. 5. Repeat step 4 every minute until your pulse returns to
normal. Do not forget to record the results each time in minutes. Time of pulse rate was taken Rate
in 30 second-interval Pulse Breathing Resting Right after 3-min exercise + 1-min after exercise + 2-
min after exercise + 3-min after exercise + 4-min after exercise Guide Questions: •How long did it
take your breathing to return to its resting rate? •How long did it take for your pulse to return to
resting rate? •Compare your results with your classmates. •Who had the fastest recovery rate? •Who
had the slowest recovery rate? Who among your classmates do you think is the “fittest”? Why do
you say so?

ENRICHMENT CARD Explain the anatomy of the Circulatory System using the illustration of the
heart below: 15.
 While many view the circulatory system as simply a highway for blood — it is also known as the
cardiovascular system — it is made up of three independent systems that work together: the heart
(cardiovascular), lungs (pulmonary) and arteries, veins, coronary and portal vessels (systemic). The
circulatory system is a vast network of organs and vessels that is responsible for the flow of blood,
nutrients, oxygen and other gases, and hormones to and from cells. Without the circulatory system,
the body would not be able to fight disease or maintain a stable internal environment — such as
proper temperature and pH — known as homeostasis. Description of the circulatory system 16.

 4. Title Card Things We Call Matter Everything around you is matter. Matter is made of atoms.
Atoms are very tiny particles that you cannot see. You need special instruments to see them. When
atoms join other atoms, they make molecules. Molecules are still very small for your eyes to see. But
when lots and lots of molecules join together, they form the things around you, that is matter. The
science that studies matter is called chemistry. Matter has mass. Mass is how much material
something has. Here on earth, mass and weight are the same. Matter has volume. Volume is how
much space a thing takes up. All matter has volume. Everything occupies space. The three states of
matter are solid, liquid and gas. Student’s Notes Please check the box. After reading this page….

flowers and seeds are found in so many varieties that you may not be able to know them all in your
lifetime. A flower, sometimes known as a bloom or blossom, is the reproductive structure found in
flowering. The biological function of a flower is to effect reproduction, usually by providing a
mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing or allow selfing
Some flowers produce diaspores without fertilization (parthenocarpy).
 3. 1. Observe the diagram of the flower. 2. Identify the four important parts of the flower according to
the labeled parts of the diagram of a typical flower. Usually, the top of the stem forms the base that
supports the flower. There are green leaf like covering at the base of the flower called sepals. A
group of sepals is called calyx. This protects the flower while it still a bud. The stamen is the male
reproductive organ of the flower. It’s part are the filament and anther. The anthe r carries the pollen
grains. The pistil is the female part of the flower. It is composed of the stigma, the style and the
ovary. The flower is the reproductive organ of the plants. Petals are the colored structures of the
flower. Some are brightly colored and some are fragrant to attract insects. People are also attracted

 11. The Basic Flower Parts The flower consists of many different parts. Some of the most important
parts being separated into both male and female parts. Male Parts Stamen This is the male part of
the flower. It is made up of the filament and anther, it is the pollen producing part of the plant. The
number of stamen is usually the same as the number of petals. Anther This is the part of the stamen
that produces and contains pollen. It is usually on top of a long stalk that looks like a fine hair.
Filament This is the fine hair-like stalk that the anther sits on top of. Female Parts Pistil This is the
female part of the flower. It is made up of the stigma, style, and ovary. Each pistil is constructed of
one to many rolled leaflike structures. Stigma One of the female parts of the flower. It is the sticky
bulb that you see in the center of the flowers, it is the part of the pistil of a flower which receives the
pollen grains and on which they germinate. Style Another female part of the flower. This is the long
stalk that the stigma sits on top of. Ovary The part of the plant, usually at the bottom of the flower,
that has the seeds inside and turns into the fruit that we eat. The ovary contains ovules. Ovule The
part of the ovary that becomes the seeds. Other Important Parts of a Flower Petal The colorful, often
bright part of the flower. They attract pollinators and are usually the reason why we buy and enjoy
flowers. Sepal The parts that look like little green leaves that cover the outside of a flower bud to
protect the flower before it opens. Flower Types Imperfect Flower A flower that has either all male
parts or all female parts, but not both in the same flower. Examples: cucumbers, pumpkin, and

7. melons. Perfect Flower A flower that has both the male parts and female parts in the same flower.
Examples: roses, lilies, and dandelion.
