Grade 6 Science Questions and Answers
- 1.
What is the SI unit (International System of Units) of speed?
- A.
M/s
- B.
Cm/kg
- C.
Km/h
- D.
V/A
Correct Answer
A. M/sExplanation
The SI unit of speed is meters per second (m/s). This unit represents the distance traveled in meters divided by the time elapsed in seconds. Meters per second (m/s) is commonly used in scientific and engineering calculations to measure the rate at which an object or person is moving. The m/s unit allows for precise and consistent measurements, making it the standard unit for speed in the International System of Units (SI).Rate this question:

What is the process by which plants make their food?
- A.
Transpiration
- B.
Photosynthesis
- C.
Translocation
- D.
Perspiration
Correct Answer
B. PhotosynthesisExplanation
Photosynthesis is the process by which plants convert water, and carbon dioxide into glucose and oxygen by fixing or absorbing sunlight. During photosynthesis, plants use chlorophyll in their leaves to capture solar energy, which is then used to convert water and carbon dioxide into glucose. This process is essential for plants to produce their own food and release oxygen into the atmosphere. Transpiration is the process of water movement through a plant. Translocation refers to the movement of sugars and other nutrients within a plant. Perspiration is the process of sweating in animals.Rate this question:

Plants do not breathe.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Plants do not have lungs like animals, but they also perform respiration. Through tiny openings called stomata, plants take in carbon dioxide and release oxygen. This process is essential for their survival, as it provides them with the energy they need to grow and carry out other metabolic activities.Rate this question:

From where does a solar cell receive its energy?
- A.
Sunlight
- B.
Artificial light
- C.
Earth
- D.
Moon
Correct Answer
A. SunlightExplanation
A solar cell receives energy from sunlight. Sunlight is the primary source of energy for solar cells because they convert solar energy into electricity via the photovoltaic effect. However, solar cells can also generate electricity from artificial light sources such as incandescent or fluorescent bulbs. These artificial light sources emit photons that can be absorbed by the solar cell's semiconductor material, allowing for the generation of electricity.Rate this question:

How many planets are there in our solar system?
- A.
7
- B.
8
- C.
9
- D.
11
Correct Answer
B. 8Explanation
There are eight planets in our solar system. This is based on the traditional definition of a planet, which includes Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto, which was previously considered the ninth planet, was reclassified as a dwarf planet in 2006.Rate this question:

What is the moon?
- A.
Satellite
- B.
Plant
- C.
Round
- D.
Glowing object
Correct Answer
A. SatelliteExplanation
The moon is considered a satellite because it orbits around a larger celestial body, which in this case is Earth. Satellites are objects that revolve around a planet or a star. The moon fits this definition as it maintains a consistent orbit around our planet. The moon is not a plant: it does not possess any characteristics of a living organism. While the moon is round, this is not the primary reason for it being classified as a satellite; objects that are not spherical and orbit around planets, such as the Martian moons Phobos and Deimos, are considered satellites. Lastly, it is not a glowing object because its illumination is caused by the reflection of sunlight rather than its own light source.Rate this question:

What is the movement of the earth on its axis called?
- A.
Revolution
- B.
Rotation
- C.
Motion
- D.
Vibration
Correct Answer
B. RotationExplanation
Rotation refers to the circular movement of an object around its axis. In this case, the Earth rotates on its axis and causes day and night. Earth’s rotation takes approximately 24 hours to complete. Revolution refers to the Earth's movement around the Sun, which takes about 365.25 days to complete. Motion and vibration are not specific to the earth's movement on its axis and do not accurately describe this phenomenon.Rate this question:

Walking on the Earth’s moon is as easy as walking on Earth.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Walking on the Earth’s moon is difficult due to the Moon’s significantly reduced gravity. The Moon has approximately 1/6th of Earth’s gravity, which means that our bodies would feel much lighter. Due to the reduced gravity on the Moon, it would be difficult to maintain balance and stability while walking.Rate this question:

What is the collection of hundreds of millions of stars in a large celestial body called?
- A.
Galaxy
- B.
Constellation
- C.
Satellite
- D.
Orbit
Correct Answer
A. GalaxyExplanation
A galaxy is a collection of hundreds of millions of stars, along with gas, dust, and other smaller celestial bodies, held together by gravity. Galaxies come in various shapes and sizes and are the building blocks of the universe. They can contain billions or even trillions of stars, along with other celestial objects like planets, asteroids, and comets. The term "galaxy" is commonly used to refer to the Milky Way, the galaxy in which our solar system resides, but there are countless other galaxies in the universe, such as Andromeda.Rate this question:

What type of objects can we see through?
- A.
Opaque
- B.
Translucent
- C.
Transparent
- D.
Any
Correct Answer
C. TransparentExplanation
Transparent objects allow light to pass through them with minimal scattering and absorption, making them see-through. This optical clarity means that we can clearly observe objects located on the other side of transparent materials, such as glass or clear plastic, without any obstruction to the view, enhancing visibility and light transmission.Rate this question:

What type of energy is stored in food that we eat?
- A.
Kinetic Energy
- B.
Thermal Energy
- C.
Chemical Energy
- D.
Nuclear Energy
Correct Answer
C. Chemical EnergyExplanation
The food we consume contains chemical energy stored within the bonds of the molecules it comprises. When we eat food, our bodies break down these molecular bonds through digestion, releasing the stored chemical energy, which is then converted into other forms of energy that the body uses to perform various functions, such as moving, growing, and repairing cells. This process is essential for maintaining life and supporting bodily activities.Rate this question:

What causes the different phases of the Moon?
- A.
The Moon's rotation around the Earth.
- B.
The Earth's rotation on its axis.
- C.
The Earth's shadow falling on the Moon.
- D.
The Moon's position relative to the Earth and Sun.
Correct Answer
D. The Moon's position relative to the Earth and Sun.Explanation
The different phases of the Moon are caused by its orbit around the Earth, changing the angle at which sunlight hits the Moon and is visible from Earth. As the Moon travels around the Earth, different portions of its side that faces Earth are illuminated by the Sun, ranging from the New Moon, where the Moon is almost entirely in shadow, to the Full Moon, where the entire face is brightly lit. This cycle is a result of the relative positions of the Moon, Earth, and Sun.Rate this question:
