Q5.  Answer in Brief.
1)      Write the benefits of ICT in science and Mathematics.
Ans  Benefits of ICT in science and mathematics are (i) ICT promotes interest during learning process. (ii) ICT provides opportunities for students to take part in co-operative activities. (iii) ICT provides variety of challenging learning processes. (iv) ICT provides the different ways for manipulating diagram and data.
2)      Define Modulation and Simulation
Ans  Modelling  : -   A modeling is a computer program that attempts to display a real life system. Or it is a virtual version of something in a real world.

Simulation  : -  Computer simulation is a technique of representing the real world by a computer program.

3)      Explain the difference between modelling and simulation .
Ans  Modelling and Simulation are the two terms usually means about the same thing.Computer modeling is a part of computer simulation, in which a 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 benefits of modeling and simulation .
Ans  The benefits of modeling and simulation are
(a)    It is cost effective.
(b)   It is time saving in training program if there are large number of participants.
(c)    It can be used at any time.
(d)   It can be tested for number of times.
(e)    It improves the efficiency of the user.
(f)    It is fast and easy to use.
(g)   It is multi-faceted , flexible and dynamic.

Q 6. Answer the following questions.
1)      Write a short note on role of ICT in science with examples.
Ans  ICT is used in today’s science by the modern world to make activities easier and more productive. The purposes for which ICT is used in science may be divided into the following broad areas , each of which covers a range of softwares and hardwares :
(1)   Collection of scientific data :  We can collect data with the help of ICT tools, Internet, e-mail, newsgroup , chat room, blogs,wiki and video conferencing etc are used as  agents for collecting information and interacting with information sources.
Eg. It is easy to collect the information for the project ‘Function of heart’ by using computer rather than library.
(2)   Visual Presentation :   The visual presentation makes concept more clear rather than oral explanation. We can present the data with the help of presentation slides.
Eg. To explain the ‘Structure of Atom’ with presentation slides
(3)   For Demonstration :  Modelling and Simulation improves the scientific understanding and develop investigative and higher order thinking skills. In science, there are some experiments which cannot be demonstrate easily in the laboratory but with the help of ICT we can give their demonstration easily and effectively.
Eg. ‘Function of digestive system’ or ‘Planetary System’
(4)   For Prediction :  We can collect the information and process and make predictions of certain things. Eg.  ‘Weather Forecasting ‘
(5)   For Interactive Education :  In science there are many programs designed to provide interaction between students and computer for interactive education . This is helpful in learning process. Eg. Computer tutorials, online books related to science.

2)      Write a short note on role of ICT in Mathematics with example.
    Ans The purposes for which ICT is used in mathematics may be divided into the following    broad areas.
(1)   Use of GUI :  Students can solve equation with graphical user interface on computer. Students can identify mistakes through computer and rectify them.
(2)   Observing Patterns :  To explore  the effect of varying values and looking for invariance and covariance . Eg In geogebra, draw a triangle & then explore the effect of varying values.
(3)   Visualize image : ICT tool helps to manipulate diagrams dynamically. This encourages them to visualize diagrams or graphs as they develop. Eg. 3D image of cuboids enables to solve Pythagaros theorem.
(4)   Observing Links :  The computer enables formulae , tables of numbers graphs to be linked readily changing one representation and observing changes in the others helps student to understand the connection between them. Eg. In GeoGebra , put two equations graphically on computer. It shows connection between them.
(5)   Exploring data : It enables students to work with real data which can be represented in variety of ways. This supports interpretation and analysis.  Eg. Student take part in online survey for collecting the information and exploring it in graphical format for analysis.

3)      What is modelling ? Explain modeling with suitable examples.
   Ans  A modelling is a computer program that attempts to display a real life system. Or it is a virtual version of something in a real world. Computer modeling is the representation of three dimensional objects on the computer, using software designed for the purpose. Computer modelling  is used in war games and disaster simulation situations which offers a safe, low cost means of creating / recreating events without any loss of man or material.
Eg. – (1) Weather forecast can be easily predicted with the help of computer model.
         (2) In automobile engineering, while designing , the safety of a vehicle can be tested and previewed.
         (3) Can train the people easily without actually putting them at risk.

4)      What is simulation ? Explain simulation with suitable examples.
 Ans    Computer simulation is the technique of representing the real world by a computer program,. Computer simulation is the special type of computer software. It creates artificial model of a system. Computer simulation brings real world experiences that causes the wonder.
Eg – (1) It is used in risky training.
         (2) It is used in research training, testing of explosive material virtually.
         (3) It is used in design. To design model of a car, machine or any industrial product of        factory.
       (4) It is used in education.
       (5) It is used in Entertainment, War games, 3D games.
