Branches of Science
It is the science of the forms of life that existed in prehistoric periods.
Paleontology
A young child constantly asks questions about the natural world, such as "Why is the sky blue?" and "How do plants grow?"
Curiosity

What is the term used to describe a material that is being dissolved in a certain mixture?
Solute
It is the study of the Earth's structure, rocks, minerals, and processes that shape its surface.
Geology
An archaeologist is examining a set of ancient artifacts that are claimed to be from a specific historical period. They used their expertise to assess the authenticity of the artifacts based on the materials used, the craftsmanship, and comparisons with known artifacts from that time.
Critical- Mindedness
A biologist collects different types of insects from a field and sorts them into groups based on their number of legs and wing structure.
Classifying
How many elements are present in the compound NaCl?

b. muddy water d. sand and water mixture
a. milk
It is the science that deals with the atmosphere and its phenomena such as weather and climate.
Meteorology
A renowned physicist acknowledges that there are still many mysteries in the universe that are beyond his current scientific understanding, even though he already made significant contributions to the field.
A physics student conducts an experiment to test how the angle of a ramp affects the distance a toy car travels when released.
Experimenting
What happens when a compound is formed?
a. Its properties remain unchanged from the elements it is composed of.
b. It becomes a mixture of all the elements.
c. Its properties become a combination of both elements.
d. It develops new properties that differ from the elements it is composed of.
d It develops new properties that differ from the elements it is composed of.
Which of the following is an example of a heterogeneous mixture?
a. air c. vinegar
b. saltwater d. mixed nuts
d. mixed nuts
It is the study about the relationship of living organisms with each other and their interaction with their surroundings.
Ecology
A geologist is studying the gradual erosion of a canyon. Over several decades, they document the slow but significant changes in the landscape as the natural forces reshape the terrain.
Patience
After conducting a series of experiments to study the effects of different fertilizers on crop growth, the grade 6 students prepared a detailed report and presented the findings to their teacher.
Communicating
What is the composition of a pure water molecule (H2O)?
a. One hydrogen atom and one oxygen atom
b. Two hydrogen atoms and one oxygen atom

a. cloud c. smog
b. whipped cream d. whole milk
c smog
It is the branch of science that focuses on earthquakes and seismic waves.
Seismology
A group of researchers studying climate change ensures that their personal beliefs and opinions do not influence their interpretation of data, allowing them to provide an unbiased assessment of the evidence.
Objectivity
An astronomer observes a star that exhibits irregular sparks in its brightness. Based on this, the astronomer interpreted that there is an orbiting exoplanet around that star, causing periodic transits in front of it.
Inferring
How do colloids differ from solutions and suspensions?
a. Colloids have larger particles than solutions but smaller than suspensions.
b. Colloids have smaller particles than solutions but larger than suspensions.
c. The particles of colloids have the same size as that of solutions but different from suspensions.
d. The particles of colloids have the same size as that of suspensions but different from solutions.
a. Colloids have larger particles than solutions but smaller than suspensions.
