Answer: "The synovial fluid in my joint capsule acts as a lubricant and helps the movement of the joint's articulating surfaces."

Explanation:

Synovial fluid is also called Synovia. It is produced by the synovial membrane. It is a thick liquid found in the cavities of synovial joints. It's function is to reduce friction by acting as a natural lubricant between the articular cartilage of synovial joints and allows ease of movement, they act as shock absorber and nourishment in the joints. Each of the joints contain synovial fluid.

Making observations is the step of scientific method in which information is obtained through the senses.  

Making an observation is the first step of scientific method where scientists gets curious about a natural occurrence or a phenomenon.

Further Explanation.

• Scientific method involves a process where researchers or scientists search for answers to certain questions and solutions to problems.
• Scientific methods are used by scientists or researchers to test a given hypothesis.

Steps involved in Scientific method

Making an observation and asking question.

• Making observation is the first step of any scientific process. The scientists make observations about a natural phenomenon.

• After making observations scientist asks a question about an observed phenomenon or pattern.  

• Observations may be qualitative where the occurrences are described in ways that do not use numbers or quantitative where observations contain numbers and other features.

Formulating a hypothesis

• Hypothesis refers to probable answers to the question asked and one that can be tested experimentally. Hypothesis is therefore a possible explanation for a given observation or occurrence.

• For the observation that we experience alternating periods of light and darkness that correspond to the movement of the sun, moon, and clouds. The hypothesis here would be; The earth rotates on its axis for 24 hours, thus, exposing one side to the sun or else the sun revolves around the earth for twenty four hours.

Designing and performing experiments

• Suitable experiments be carried out  to test the  validity of the hypothesis formulated.

• Experiments refers to organised measurements or observations normally made under controlled environment.

Accept or modify the Hypothesis  

• The experiment conducted helps the researchers or scientists to determine whether the hypothesis formulated is valid. If the hypothesis is valid then they proceed to the next step of scientific method.

• However, if the experiments demonstrate that the hypothesis is incorrect then it must be corrected for further experimentation.

Developing a law and/or a theory  

• After conducting experiments and analyzing the results obtained, the researchers may test whether the results are reproducible and hence a law may formulated to allow general prediction.

• A scientific law describes a phenomenon or pattern, it describes what happens but does not explain why.

Key words: Scientific method, making observation

Explanation:

A solar eclipse is a natural phenomenon caused by the interposition of the Moon between the Sun and Earth. Solar eclipses have a fairly short duration, they can only be seen in their entirety for a few minutes, unlike lunar eclipses that can be observed for several hours.

In general these eclipses can occur approximately twice a year.
