Moon is between the Sun and the Earth. The Moon appears totally dark, like there is no moon, because it is blocking the light from the Sun.

At this point, the Moon has traveled 7 days or ¼ of the way through its orbit. From our perspective, half of the Moon is illuminated by the Sun.

Which Phase of the moon : It is observed when the Earth is in between the Moon and the Sun. The full disc of the Moon is illuminated.

This phase means the Moon has just one more (the last) quarter to complete one revolution. From our perspective, half the Moon is illuminated by the Sun.

Arrange the Phases of the Moon

_____________means the lighted part of the Moon

_____________means the lighted part of the Moon is decreasing.

______________comes frpm a Latin word meaning “humpbacked,” referring to the curved lit area on the Moon’s surface.

Group of stars that appears to form a pattern or figure like bear, scorpion, dog, hunter etc.

Group of stars called the Hunter or “Balatik. -This signals Filipinos to start planting and set traps to protect the crops from animals.

Group of stars called “Moroporo” , The tagalogs refer to this star cluster to know the shifting of time and season. It is also signifies the start of the planting season.

Group of stars called “Lepu” The farmers clear their fields while waiting for the harvest time.

Hot balls of glowing gases They shine because of the process called fusion

The moon appears full when the Earth is between the moon and the sun. In both cases, the gravitational pull of the sun is t; to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. This means that high tides are a little higher and low tides are a little lower than average.

+++++++++++++++occur during the first and third quarter moon, when the moon appears ;half full. The sun and moon are at right angles to each other. When this happens, the bulge of the ocean caused by the sun partially cancels out the bulge of the ocean caused by the moon.

Check Significances of the moon and stars

A short – lived weather disturbance with lightning, thunder, dense clouds, heavy rain or hail, and strong gusty winds

A violent swirling funnel-like cloud; spins at speed creating destructive force in its path

An intense circular storm that forms over oceans and is characterized by low pressure area, strong winds and heavy rains; lasts longer than thunderstorms

PAGASA stands for

Rainfall Warning with 30 mins of rain . Serious flood warning and Response in EVACUATION

A  [[1]] is a push or pull upon an object resulting from the object [[2]] with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction  [[3]] , the two objects no longer experience the force. Forces only exist as a result of an interaction.

Which are the effects of force

Process of changing an object’s position

Measure the amount of space between two things or places

Distance traveled by an object per unit time

Change in speed or direction or both

The [[1]] of an object is the rate of change of its [[2]] with respect to a [[3]] , and is a function of [[4]] . It is equivalent to a specification of an object [[5]] and direction of [[6]] .

types of Electricity results from an imbalance between negative and positive charges in objects.

Electrical energy / Electric circuit:  [[1]] negatively charged  [[2]] are neutral or electrically neutral (no charge) [[3]] positively charged

Heat is a thermal energy that transfers from objects with high temperature to objects with lower temperature. - Heat can transfer through the following:

Light travels in a [[1]] line. It is [[2]]when objects allow most light pass through. [[3]]object allow some light to pass through. [[4]]Objects block light. - A [[5]] forms when light is blocked.

____________produced by the vibrations of the particles of an object.

sharpness of a sound

loudness of a sound

number of vibrations or sound waves per second

Sound intensity levels are measured in units

Weathering is the process of [[1]] large pieces of rocks to smaller one. [[2]] weathering - Changes the size of rocks, [[3]] weathering - Changes the composition of rocks, Four agents of erosion: 1. Water - 2. Wind - 3. Ice - 4. Gravity

++++++++++++Action of picking up and moving weathered materials

Dropping of weathered materials to another location
