6th Grade End of Year Science Quiz

What is an example of a predator-prey relationship in an ecosystem?

• Bird building a nest

• Fish swimming in a pond

• Rabbit eating grass

• Lion hunting a zebra

How do plants and animals interact in an ecosystem?

• Animals provide oxygen for plants

• Plants provide food and oxygen for animals, while animals help in pollination and seed dispersal for plants.

• Plants and animals have no interaction in an ecosystem

• Plants eat animals for survival

What are the different Earth's systems and how do they interact with each other?

• The Earth's systems consist of mountains, oceans, and forests; they interact through earthquakes

• Earth's systems include Mars, Venus, and Jupiter; they interact through gravitational pull

• The different Earth's systems are land, sea, and air; they interact through volcanic eruptions

• Geosphere, hydrosphere, atmosphere, and biosphere; they interact through processes like the water cycle, carbon cycle, and rock cycle.

Explain the water cycle and its importance in Earth's systems.

• The water cycle is important for maintaining the Earth's water supply, regulating the climate, and supporting various ecosystems.

• The water cycle is important for controlling the population of marine life.

• The water cycle is important for creating new landmasses and mountains.

• The water cycle is important for regulating the Earth's magnetic field.

What are the different forms of energy and how are they related to waves?

• Mechanical, thermal, and electrical energy are not related to waves

• Mechanical, thermal, electrical, radiant, chemical, and nuclear energy are related to waves through the transfer and propagation of energy.

• Radiant, chemical, and nuclear energy have no connection to waves

• Waves are only related to sound and water, not other forms of energy

How do waves transfer energy?

• Through the absorption of heat

• Through the release of sound waves

• Through the movement of particles or through the propagation of electromagnetic fields.

• Through the reflection of light

What are the different types of waves found in the universe?

• Radio waves, microwaves, and ultraviolet waves

• Sound waves, light waves, and heat waves

• Alpha waves, beta waves, and theta waves

• Electromagnetic waves, gravitational waves, and matter waves

What are the major achievements in space exploration?

• Discovering alien life on Mars

• Building a space hotel

• The major achievements in space exploration include landing on the moon, launching the Hubble Space Telescope, and sending rovers to Mars.

• Sending astronauts to Jupiter

Explain the process of photosynthesis in plants.

• Plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.

• Plants use moonlight, nitrogen, and oil to produce sugar and carbon dioxide.

• Plants use water, oxygen, and sunlight to produce carbon dioxide and glucose.

• Plants use soil, nitrogen, and sunlight to produce water and oxygen.

What are the different parts of a cell and their functions in biology?

• The different parts of a cell include the cell membrane, cytoplasm, nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and ribosomes. Each part has its own specific function in maintaining the cell's overall health and function.

• The different parts of a cell include the skin, hair, and nails. They provide protection and support for the cell.

• The different parts of a cell include the heart, lungs, and liver. They are responsible for the cell's respiration and metabolism.

• The different parts of a cell include the brain, spinal cord, and nerves. They control the cell's movement and coordination.
