**(1) Write the benefits of ICT in Science and Mathematics.**

Ans. Interactive multimedia software’s make
science and mathematics more intresting.ICT provides opportunities for
collaborating with peers, professionals and scientists.ICT provides project
based learning. It provides different ways of managing data and graph.ICT
reduces the mathematical aspect of practical work, feeling the students to
concentrate on interpreting and analyzing data.

**(2) Define modeling and simulation.**

Ans. Modeling- A modeling is a computer
program that attempts to display a real life system. Or it is a virtual version
of something in the real world. Modeling represents three dimension objects.
Eg: Car model

Simulation- It is a special type of computer
software to create artificial model of a system. It offers hands on activities
that feel like the real experience. Eg : Flight simulation.

**(3) Explain the difference between modeling and simulation.**

Ans. These two terms usually means, about the
same thing. Computer modeling is the part of the computer simulation, in which
digital model of an object is built which is designed to work like the real
thing. The computer can then use this model to simulate various different
conditions which the real object may have to deal with.

**(4) Explain the benefit of modeling and simulation.**

Ans. Modeling is cost effective. It is time
saving if there are large number of participants. Modeling can be used at any
time. It can be tested for number of time. Modeling increases the efficiency of
the user. Modeling is fast and easy to use. It is multifaceted, flexible and
dynamic.

**Q.6 Answer the following questions.**

**(1) Write a short note on role of ICT in science with examples.**

Ans.

**Collection of scientific data.-**ICT tools are used to record and store measurement electronically. Eg: Computer controlled microscopes and instruments, digital video recording are used to record and store measurements/**Visual presentation –**Facilitate better understanding of concepts and process. Instant feed back provided by spreadsheet enables learners to see the effect of changing values. Eg:using spreadsheet and Graph tools for data handling and analysis, data can be presented in more visual and clear form.

**Modeling and simulations for demonstration and prediction-**Animation enables teachers to demonstrate experiments and environments that would not otherwise be possible. Simulations eliminate experimental errors and increase visual impact. Eg : Planetary system.

**Interactive education and information resource. -**Models are simulated and explore a wide variety of physical phenomena. Eg : Simulation videos from internet.

**(2) Write a short note on role of ICT in mathematics with examples.**

Ans.

**Graphical User Interface –**It encourage the learners to explore, make mistakes, see the consequences of their decision and rectify.**Observing Patterns**- The ICT enables students to look at sufficient cases of mathematical problems by changing values, observe patterns from the invariance and covariance in the result.

**Observing links and connections-**A computer enables to readily link an equation, a table of numbers and graph. The student realize they are different representation of same thing. Eg; Geogebra can graph directly from two equation.

**Manipulating Diagrams or graphs dynamically-**Using ICT tools helps students to develop the capability to visualize and generate their own mental image.Eg: Geogebra.

**(3) What is modeling? Explain with suitable examples.**

Ans- Modeling is a virtual representation of
real world systems in the language of mathematical equations. Modeling aim to
describe the different aspects of the real systems and their interaction
through mathematics. Mathematical equations of a model are translated into computer
algorithms the can be treated and solved by ever powerful computers.

**Uses**

Model are used to quickly explore new
solutions and innovations, that can save time and money in the development and
validation phases.

For weather prediction, mathematical model of
atmospheric motions are based on well know equations and phenomena.

**(4) What is simulation? Explain with suitable examples.**

Ans. Simulation is the process of designing a
mathematical model of a real or imagined system and conducting experiments with
model. It generally refers to a computerized version of model which is run over
time to study the implications of the defined interactions. A simulation bring
a model to life and shows how a particular object or phenomenon is likely to
behave. Simulation proves to be cheaper, safer and faster in all fields of
engineering, applied science, medicine, biology, economics and applied
mathematics.

**Uses**

Simulation techniques are used in
the designing new efficient systems. Eg: Car engines, complex air routing plan.

Training simulations thoroughly prepare
trainee to react to various situations until the correct response are learned.
Eg : Flight simulator or ship simulator model dangerous environments and life
threatening situations, so that aircraft pilots or a ship officers are well
experienced about an aircraft or ship behavior.

Simulation techniques are used to create computer games for
entertainment.
