Gravity
A roller coaster car starts from the highest point and speeds up going down the track. What type of energy transformation happens?
Electrical energy → Light energy
Chemical energy → Sound energy
Nuclear energy → Gravitational Potential energy
Potential energy → Kinetic energy
When you turn on a battery-operated fan, which type of energy makes the blades move?
Chemical energy from the battery
Solar energy from sunlight
Gravitational energy from height
Sound energy from the motor
A large windmill near the beach spins rapidly on a windy day. Why are the blades moving?
The ground is vibrating
The sun is heating the blades
The wind transfers kinetic energy
A battery inside the windmill spins it
Why is wind considered a good energy source for generating electricity?
Wind creates random motion and is unreliable
Wind energy is mostly wasted as heat
Wind energy easily converts kinetic to electrical energy
Wind energy mainly produces sound, not electricity
Lighting a barbecue grill using charcoal shows a transformation of energy. What type of energy transformation is happening?
Chemical energy into heat, light, and sound
Heat energy changing into chemical energy
Light and sound turning into chemical energy
Mechanical energy keeping the grill burning
When you plug in a toaster, what energy transformation happens?
Electrical to light energy
Electrical to kinetic energy
Electrical to heat energy
Electrical to chemical energy
Lighting a scented candle during a blackout transforms its chemical energy into:
Sound and light energy
Thermal and light energy
Kinetic and chemical energy
Gravitational and nuclear energy
A student charges a solar battery during a sunny day and uses it to power a lamp at night. What energy transformations happen?
Light energy → Electrical energy → Light energy
Sound energy → Light energy → Heat energy
Chemical energy → Heat energy → Light energy
Kinetic energy → Gravitational energy → Light energy
A worker pushes heavy boxes up a wooden ramp to a truck. What type of simple machine is the ramp?
Lever
Wedge
Screw
Inclined plane
During a stage play, a curtain is lifted using a system of ropes and wheels. How do simple machines help in this case?
They slow down the lifting
They increase the force needed
They make lifting faster and easier
They produce their own energy
A family stores knives and scissors on a high shelf in their kitchen. Why is this important for safety?
Children can play with sharp tools safely
Sharp objects should be within easy reach
Sharp objects should be hidden under couches
Sharp tools must be kept out of children’s reach
Which statement about earthquakes is incorrect?
Earthquakes are caused by the movement of tectonic plates.
Earthquakes can only occur on land.
Earthquakes can cause tsunamis.
Earthquakes are measured using the Richter scale.
After a volcano near their town erupts, a family covers their windows and wears masks. Why do they take these actions?
To protect themselves from ashfall
To watch the eruption closely
To enjoy the cool weather
To collect ash for fertilizer
After a powerful volcanic eruption, what major change can happen to the land around the volcano?
A new mountain range immediately forms.
The land becomes completely dry like a desert.
The environment stays almost the same.
Thick layers of ash and rock cover and reshape the area.
Why is the Philippines more prone to volcanoes and earthquakes?
Because it’s near the equator
Because it’s surrounded by deserts
Because it is along tectonic plate boundaries
Because of frequent monsoons
How can earthquakes and volcanic eruptions create new landforms?
They break mountains into smaller pieces
They lower the ground underwater
Earthquakes cause land to rise; volcanoes build new land with lava
They remove land through strong winds
What mainly causes a volcano to erupt?
Strong wind pressure
Heavy rains filling the crater
Sun heating the Earth’s surface
Movement of magma beneath the Earth's surface
Before building a bridge in a city known for earthquakes, engineers want to test its strength. What is the best thing they should do?
Test a small model with earthquake simulations
Test the full-size bridge after building it
Use the same tests from a different country
Wait for an earthquake to test it naturally
What is the best way to make buildings safer from earthquakes in the Philippines?
Focus only on rescue teams
Remove all tall buildings
Use flexible materials and strong building codes
Build taller structures for more space
Which set of actions are good precautions before and during an earthquake?
I. Keep emergency food and water ready.
II. Stay inside a moving car while the ground is shaking.
III. If outside, move to an open space away from trees or buildings.
IV. Put heavy and breakable items above beds for easy access.
I and II
II only
