20. Activity 4 Unlocking terms
Place cards containing the definitions
to the correct vocabulary word that it is
describing about the lessons to be
discussed.

21. Activity 4 Unlocking terms
*Polar molecule - A neutral, or uncharged molecule that has an
asymmetric internal distribution of charge, leading to partially positive
and partially negative regions
*Cohesion - The attraction of molecules for other molecules of the same
kind
•Adhesion - The attraction of molecules for other molecules of a
different kind
•Density - The mass per unit volume of a substance
•Specific heat capacity - The amount of heat needed to raise the
temperature of one gram of a substance by one degree Celsius
•Heat of vaporization - The amount of energy needed to change one
gram of a liquid substance to a gas at constant temperature

23. MOLECULAR STRUCTURE OF WATER
The oxygen atom has 8 electrons, and each hydrogen
atom has 1 electron. The covalent bond is formed when
atoms of hydrogen share electrons with an oxygen atom.

24. MOLECULAR STRUCTURE OF WATER
Water (H2O) molecule is polar with strong
intermolecular forces. It forms a special dipole
bond called a hydrogen bond. Four hydrogen
bonds can be formed in a water molecule .
These bonds are strong, however, it is constantly
breaking, shifting and re-forming giving the water
its unusual properties

25. Water Properties
Capillary Action
Intermolecular forces also cause a polar liquid like water to rise
against gravity into a small-diameter tube (a capillary). This is also
because the molecules of water are attracted to the substance in the
tube.This phenomenon is called capillary action. When a glass tube
is placed in water, the water rises into the tube. Water rises higher in
a tube with a smaller diameter.

26. Water Properties
Capillary Action in Plants

27. Surface Tension
- molecules attract with other water molecules
forming a bond that creates an elastic film on
the surface of water resulting to surface
tension. Surface tension allows the surface of
the water to support weights and pull water
droplets into round shapes.

28. Surface Tension

29. Surface Tension
Paper clip is made of steel
and with higher density,
but it can float on the
surface of water because
of high surface tension of
water.

30. Surface Tension
Water striders can walk on
top of water. This is
because of the high
surface tension of water,
and water striders also
have distributed weight
and highly adapted legs.

31. Surface Tension
When drops of water will be
added to the coin and reach the
coin’s edge, dome of water will
be formed on top of the coin.
This is the result of the water
molecules clinging to one
another forming an optimal
shape. This shows cohesion
and surface tension of water.

32. Viscosity
Water has a viscosity of 1
centipoise or 0.001 Pa/s at 20 oC.
Polar water is more viscous than
nonpolar liquids like liquid nitrogen.
But compared to long-chain
molecules, water is less viscous.
Water has a low viscosity because
it is not a long-chain molecule.

33. Universal Solvent
Water has a unique ability to dissolve many chemical
substances. It can dissolve salts and other ionic
compounds, polar covalent compounds like alcohols,
and gases like oxygen and carbon dioxide. Nutrients
needed by plants are dissolved in water and are
absorbed by plants. Water can also absorb pollutants
from farming and industrial plants resulting in water
pollution.

34. Universal Solvent

35. Boiling Point
is unusually high. Water boils at 100
oC. Due to intermolecular forces, the
water stays to be in a liquid state at a
large range of temperatures. During
summer days, a pond does not dry
quickly because the amount of
energy required to evaporate the
water is so high.

36. Density
Solid water is less dense and floats on liquid water. The
molecules in solid water are different than they are in
liquid water. In solid water, the hydrogen bonds have
an open structure with unoccupied spaces, resulting in
a larger volume. This makes solid water or ice
becomes less dense causing ice to float on water. In
temperate countries, water bodies freeze. Ice will float,
causing the aquatic organisms to still live and survive
under the surface which remains liquid.

37. pH-
pH is a measure of how acidic/basic water is. The
range goes from 0 to 14, with 7 being neutral. pHs of
less than 7 indicate acidity, whereas a pH of greater
than 7 indicates a base. pH is really a measure of the
relative amount of free hydrogen and hydroxyl ions in
the water.
Pure water has a pH of 7 and is considered “neutral”
because it has neither acidic nor basic qualities

41. Review on Percentage.
A percentage is another way of recording
a fraction with a denominator of 100 (out
of 100). A percentage sign % is used to
display percentages, for example 85 out
of 100 (85/100) can be written as 85%
