g)      What is scientific learning?

Scientific learning is the process of following systematic way to learn the facts.

3. Short answer questions.

a)      Define science process skill and list them.

The rules that must be followed while learning scientific processes are called science process skill.

b)      What do you mean by practical work of science? Give four examples.

The activity in which students must involve themselves to understand the key knowledge of the theory by using all known science process skill is called practical work of science.

c)       What is hypothesis? How is it formed?

Hypothesis is a plan or an idea that can be tested by experiments is called hypothesis. Hypothesis is formed on the basis of observation of the problem and finding the background of the study.

d)      Define analysis. What is its importance?

Analysis is the process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making. It is important to draw conclusion on the basis of the obtained data.

e)      What is meant by observation? What is its advantage?

Observation is the act of collecting information from surrounding environment, events, processes, objects, etc. It help in formulation of hypothesis and analyzing the experiment.

f)       What is a survey?

A survey is a research method to collect data from the predefined group of respondent to gain information and insights into various topics of interest.

g)      Define scientific report. Mention its importance.

A complete description of scientific research or practical work is called a report. Its importance is that it let the audience to know the importance of our research or practical work

h)      How is scientific survey carried out?

Scientific survey is carried out by following the steps given below:

i) Selection of objective

ii) Formation of hypothesis

iii) data collection

iv) Data analysis

v) Drawing conclusion

 vi) Report writing

i)        Scientific learning is very important for society. Give reason.

Scientific learning removes the superstitious by finding the clues and logical reason behind any facts. It also introduces new technology in medicine, agriculture, education, space exploration, environmental conservation and transportation. Thus, scientific learning is very important for society.

j)        Students should take part in practical work. Why?

Students should take part in practical work because of the following reasons:

                                 i.            It involves everyone in doing scientific work.

                               ii.            It generates lifelong interest in science.

                              iii.            It brings theory into real practice.

                             iv.            It helps in generation of new ideas about the existing knowledge.

k)      Observation is the most important skill of scientific learning. Why?

Observation involves the perception and recognition of the subject of importance or significant. Observation is most important skill of scientific learning because it enables the scientists to collect and record the data that are used in formulation of hypothesis and theories.

l)        Research is popular method for scientific learning. Justify.

Research is a popular method for scientific learning because it allows the scientists to collect and analyze the data systematically to answer the question and to test the hypothesis. Different methodological tools used in research enable the scientist to reach to the exact cause and effect relationship and to develop new theories.

m)    Sampling is important during survey. Give reason.

Sampling enables the researcher to collect the data from a large population. Sample is the representation of the source of primary data and it supports the research work to develop the pattern and relationship between various data.

n)      We should not eat in the laboratory. Why? a)      or The teacher asks us not to bring food and drinks into the lab. What might be the reasons?

We should not eat in the laboratory because we touch different kinds of chemicals, fumes and gases are produced in the laboratory during experimental work. These gases and chemicals may enter inside our stomach along with food which may harm us.

o)      Observation and inquiry are important for survey. Why?

Observation and inquiry are important for survey because they help in the collection of accurate and reliable data through recording  events or behavior and asking question from the respondents.

a)      Available data should be listed properly. Give reason.

Available data should be listed properly because proper listing of data supports better analysis and manipulation of the data.

b)      A report is very important part of scientific learning. Why?

A report is very important part of scientific learning because it is the method to communicate the findings of a a research with the scientific community and experts.

c)       Write the differences between observation and hypothesis.

The differences between observation and hypothesis are:

Observation	Hypothesis
1. It is an act of sharp recording or watching an event or behavior.	It is a tentative explanation of an observation, phenomenon or problem.
2.Observation is the primary step of scientific learning.	Hypothesis is produced on the basis of observation.

 

d)      What are the differences between sampling and experimenting?

The differences between sampling and experimenting are:

Sampling	Experimenting
1. It is the process of selecting a small portion of a population to provide statistical information about the population.	Experimenting is the method to test the validity of hypothesis.
2. By selecting sample from a population, researcher makes an inference about a large population.	By experimenting researcher find out new facts or bring new insight in the previous work.

a)      Differentiate between hypothesis and conclusion.

Hypothesis	Conclusion
1. It is a tentative explanation of an observation, phenomenon or problem.	The result of an experiment or investigation is called conclusion.
2. A hypothesis is made after observation of a phenomenon or event.	Conclusion is drawn after an experiment or investigation on the basis of evidences.
