Science for grade 1 Questions and Answers
- 1.
Which of these is a vegetable?
- A.
Cabbage
- B.
Watermelon
- C.
Apple
- D.
Leaf
Correct Answer
A. CabbageExplanation
Cabbage is a vegetable because it is a leafy green plant that is commonly used in cooking and is known for its dense, rounded heads of leaves. It is often used in salads, stir-fries, and soups, and is a good source of vitamins and minerals. Watermelon and apple, on the other hand, are fruits, and while a leaf is a plant part, it is not typically considered a vegetable.Rate this question:

Which is the food factory of a plant?
- A.
Root
- B.
Stem
- C.
Leaf
- D.
Tree-top
Correct Answer
C. LeafExplanation
The leaf is considered the food factory of a plant because it contains specialized cells called chloroplasts that are responsible for photosynthesis. During photosynthesis, the chloroplasts use sunlight, water, and carbon dioxide to produce glucose (sugar) and oxygen. The glucose is then used by the plant as a source of energy for growth and development.Rate this question:

What organ helps a mammal with breathing?
- A.
Gills
- B.
Not Here
- C.
Lungs
- D.
Pistil
Correct Answer
C. LungsExplanation
Lungs help mammals to breathe by taking in oxygen from the air and removing carbon dioxide from the body. They are the main respiratory organs in mammals and are responsible for the exchange of gases between the body and the environment.Rate this question:

What organ helps fishes to breathe?
- A.
Gills
- B.
Lungs
- C.
Both
- D.
None
Correct Answer
A. GillsExplanation
Fish have gills, which are specialized organs that allow them to extract oxygen from water. Gills are located on the sides of the fish's head and are made up of thin, feathery filaments. As water passes over these filaments, oxygen is extracted and absorbed into the fish's bloodstream, while carbon dioxide is released back into the water. This adaptation enables fish to respire efficiently in their aquatic environment. Unlike lungs, which are found in terrestrial animals, fish rely solely on their gills for respiration.Rate this question:

Which of these objects is man-made?
- A.
Stone
- B.
Coal
- C.
Bike
- D.
Water
Correct Answer
C. BikeExplanation
Stone and coal are natural resources that are not made by humans. Water is a natural element that exists in nature. On the other hand, a bike is a man-made object that is created by humans for transportation purposes.Rate this question:

Which of these objects is not man-made?
- A.
Apartment
- B.
Road
- C.
Swimming pool
- D.
Mountain
Correct Answer
D. MountainExplanation
A mountain is a natural geographical feature that is formed through natural processes such as tectonic activity and erosion. It is not created or constructed by humans, unlike an apartment, road, or swimming pool, which are all man-made structures.Rate this question:

Fire requires oxygen to burn.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Fire requires oxygen to burn because oxygen is a key component in the process of combustion. When a fire occurs, it is a chemical reaction between a fuel source and oxygen. In the presence of oxygen, the fuel undergoes oxidation, releasing heat and light energy. This process is known as combustion. Without oxygen, the fire cannot sustain itself and will eventually be extinguished.Rate this question:

Where can't humans breathe?
- A.
In caves
- B.
On mountain
- C.
Underwater
- D.
In jungle
Correct Answer
C. UnderwaterExplanation
Humans cannot breathe underwater without the aid of special equipment like scuba gear or a submarine. Unlike fish, humans do not have gills to extract oxygen from water. Therefore, being submerged in water for an extended period of time without proper breathing apparatus would result in suffocation.Rate this question:

Which organism is the largest land animal?
- A.
Elephant
- B.
Lion
- C.
Horse
- D.
Dog
Correct Answer
A. ElepHantExplanation
The largest land animal is the elephant. Elephants are known for their massive size and can weigh up to several tons. They have a long trunk, large ears, and tusks. They are herbivores and are found in various habitats, including forests, savannahs, and grasslands. Elephants play a vital role in maintaining the ecosystem by creating water holes and clearing pathways in forests. They are highly intelligent and social creatures, living in herds and displaying complex social behaviors. Due to habitat loss and poaching, elephants are currently endangered, making their conservation a significant concern.Rate this question:

Where do we get light from?
- A.
The moon
- B.
The oceans
- C.
The asteroids
- D.
The Sun
Correct Answer
D. The SunExplanation
The Sun is the correct answer because it is the primary source of light in our solar system. It emits light and heat through a process called nuclear fusion, where hydrogen atoms combine to form helium and release energy in the form of light. The moon reflects sunlight, but it does not produce its own light. The oceans and asteroids do not emit light either.Rate this question:

Which part of the plant grows underground?
- A.
Flower
- B.
Leaf
- C.
Stem
- D.
Roots
Correct Answer
D. RootsExplanation
Roots are the part of the plant that grows underground. They are very important because they help anchor the plant in the soil and absorb water and nutrients from the ground, which the plant needs to grow. Roots also store food for the plant. While the other parts of the plant, like flowers, leaves, and stems, are above ground and visible, roots are typically hidden beneath the surface but play a crucial role in the plant’s health and survival.Rate this question:

What do we breathe in to stay alive?
- A.
Water
- B.
Oxygen
- C.
Dust
- D.
Smoke
Correct Answer
B. OxygenExplanation
We breathe in oxygen because our bodies need it to produce energy through a process called respiration. When we breathe, oxygen from the air enters our lungs and is transferred to our blood. The blood then carries the oxygen to all the cells in our body. In the cells, oxygen is used to convert the food we eat into energy. This energy is necessary for all our bodily functions, from moving and thinking to growing and repairing tissues. Without oxygen, our cells would not be able to produce energy, and we would not be able to survive.Rate this question:

Where does the sun go at night?
- A.
It goes to sleep
- B.
It hides behind clouds
- C.
The Earth rotates
- D.
It goes under the sea
Correct Answer
C. The Earth rotatesExplanation
The sun does not actually move or go anywhere at night. Instead, the Earth rotates on its axis. This means the Earth spins around like a top. As the Earth rotates, different parts of the world move into and out of the sun’s light. When it is daytime where we live, our part of the Earth is facing the sun and receiving sunlight. When it is nighttime, our part of the Earth has rotated away from the sun and is in shadow. This rotation of the Earth is why we experience day and night.Rate this question:

What season comes after winter?
- A.
Summer
- B.
Spring
- C.
Fall
- D.
Monsoon
Correct Answer
B. SpringExplanation
Spring comes after winter in the cycle of the four seasons. Winter is the cold season, and spring follows it, bringing warmer weather. During spring, the days get longer, temperatures rise, and many plants start to grow and bloom. Animals also become more active. Spring is often associated with renewal and new beginnings as the natural world awakens from the dormancy of winter. This seasonal cycle continues with summer following spring, bringing the warmest weather of the year.Rate this question:

What do we use to see things around us?
- A.
Nose
- B.
Ears
- C.
Eyes
- D.
Mouth
Correct Answer
C. EyesExplanation
Our eyes are the organs we use to see the world around us. They detect light and allow us to recognize shapes, colors, and movement, helping us to understand our environment. The eyes work by receiving light and sending signals to the brain, where the information is processed to create the images we see. Without our eyes, we would not be able to perceive the visual details of the world, making them one of our most important senses. The other options, like ears, nose, and mouth, are used for hearing, smelling, and tasting, respectively.Rate this question:
