Science For Grade 6 Students Trivia
1.
What is Mass?
Answer:
The amount of matter in a particle or object.
Explanation:
Mass is a fundamental property of matter that measures the amount of matter in an object or particle. It is commonly measured in kilograms and is different from weight, which is the force exerted on an object due to gravity. Mass remains constant regardless of the location, while weight can vary depending on the strength of gravity.
2.
What is length?
Answer:
The distance between 2 points
Explanation:
Length refers to the distance between two points. In this context, the question is asking for the length between two points. The other options, such as the distance between 100 points, 4 points, or 1000 points, are not relevant to the question as they are not asking for the length between two specific points.
3.
What is the function of blood cells?
Answer:
To carry oxygen around the body.
Explanation:
The function of blood cells is to carry oxygen around the body. This is accomplished by the red blood cells, which contain a protein called hemoglobin that binds to oxygen in the lungs and transports it to the body's tissues. Oxygen is essential for cellular respiration, the process by which cells produce energy. Without the oxygen-carrying function of blood cells, the body's tissues would not receive the necessary oxygen for proper functioning.
4.
I have dry, scaly skin, breathe with lungs, and lay shelled eggs. My relatives are dinosaurs, lizards, snakes, etc. What type of animal am I?
Answer:
Reptiles
Explanation:
Reptiles, a diverse group of vertebrates, are characterized by several distinctive features that set them apart from other animal classes. They possess dry, scaly skin, which helps prevent water loss in arid environments, making them well-suited to a variety of terrestrial habitats. Unlike amphibians, reptiles breathe exclusively with lungs, even from the moment of birth, which is a more efficient respiratory system allowing for greater stamina and activity levels.
5.
What is the darkest part of the shadow?
Answer:
Umbra
Explanation:
The darkest part of a shadow is called the umbra. When an object blocks the light source completely, it creates a region behind it where no direct light can reach, resulting in a dark shadow. This area is known as the umbra. The penumbra, on the other hand, refers to the partially shaded region surrounding the umbra where some light is still able to reach. Hyperumbra is not a recognized term in the context of shadows.
6.
What is the primary source of energy for Earth?
Answer:
The Sun
Explanation:
The Sun is the primary source of energy for Earth, providing the necessary light and warmth for life to exist. Solar energy drives Earth's climate and weather and supports nearly all life through photosynthesis, where plants convert solar energy into chemical energy. While other sources like geothermal heat and the Moon affect the Earth, they do so to a much lesser extent compared to the Sun.
7.
Which gas is most abundant in Earth's atmosphere?
Answer:
Nitrogen
Explanation:
Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of the air we breathe. Oxygen, which is essential for life, makes up about 21%, while other gases such as carbon dioxide and argon make up the rest. Nitrogen is crucial for many biological processes and helps form proteins in living organisms, but it is inert and does not participate directly in Earth's weather or climate.
8.
What process is primarily responsible for shaping the surface of the Moon?
Answer:
Meteor impacts
Explanation:
Meteor impacts are primarily responsible for shaping the surface of the Moon. The Moon's surface is covered with craters formed by the collision of meteoroids, asteroids, and comets. Unlike Earth, the Moon lacks significant atmospheric erosion, volcanic activity, and plate tectonics, making meteor impacts the dominant process in shaping its surface.
9.
What is the role of chlorophyll in plants?
Answer:
To capture sunlight
Explanation:
Chlorophyll is a green pigment found in the chloroplasts of plant cells and is crucial for photosynthesis, the process by which plants convert light energy into chemical energy. Chlorophyll absorbs light, most efficiently in the blue and red wavelengths, and uses this energy to convert carbon dioxide and water into glucose and oxygen. This is essential for plant growth and providing energy for life on Earth.
10.
Which element is most essential for the construction of electronic circuits?
Answer:
Silicon
Explanation:
Silicon is a fundamental element used in the construction of electronic circuits. It is used as a semiconductor material in microchips and transistors, the building blocks of modern electronics. Silicon's properties allow it to conduct electricity under certain conditions, making it ideal for controlling electronic signals. This has made it the backbone of the digital and technology revolution, from computers to smartphones.
