Lesson No.3 ICT in Science,
Mathematics, Modeling and Simulation
1. Write a short note on
role ICT in Science with examples..
Ans. The use of Computers, the associated Hardware, Software and other digital equipment allows ICT to be used in Science in the following areas: Collection of Scientific Data: Using ICT tools such as the Internet, email, newsgroups, blogs and conferencing, the collection of data is faster, easier and more accurate. This improves the quality of results. Example: Computer controlled equipment can be used to directly record and store real time measurements. To establish certain abstract concepts: Some concepts which cannot be proved easily explained can be understood very well through computer technology. Example: The Structure of the Atom can be more easily explained using a PowerPoint presentation or an animation. For demonstration of experiments: In Science many experiments cannot be demonstrated live. However using ICT one can easily understand these experiments. Computer Simulations are used extensively for demonstration of various concepts. Example: The study of Volcanoes, the human digestive system, or our Solar System becomes easy using ICT tools. For Prediction: Since collection of data becomes easy using ICT tools, we can use this data to predict events. The existing data can be extrapolated to understand things for which there is no direct information available. Example: ICT is used extensively in Weather Prediction and Remote Sensing applications. For Interactive Education: Understanding scientific concepts becomes easy when interactive methods are used. Students can interact with the software and easily grasp complex scientific topics. Example: Most educational software provides teaching in an interactive way. 

2. Write a short note on role ICT in Mathematics with
examples.
Since the computer is capable of performing a large number
of complicated calculations in a short time, it is easy to use ICT in
learning Mathematics. ICT is used in Mathematics in the following areas.
Use of GUI: The use of a GUI provides a quick way to visually study the effect of changing values or parameters in a given calculation. Example: 3D image of graphs, cuboids, etc. Observing Patterns: Using a Mathematics software allows us to observe the effects of changing values. These varying values can be then studied for invariance and covariance. Example: Using Geogebra, we can draw a geometric figure and then study the effect of changing the lengths of the sides or of the angles. Observing Links: The Mathematics software allows formulae, tables of numbers and graphs can be linked readily. By changing values we can observe the connection between them. Example: In Geogebra we can input two equations and plot them in the Graphical View. The connection between these two equations will then be shown graphically. Visualizing images: ICT has several tools which allow one to manipulate diagrams dynamically. This encourages them to visualize diagrams or graphs as they develop. Example: A 3D image of a Cuboids can be used to solve Pythagoras’ theorem. Exploring Data: By using Computers a student can work with real data that can be represented in different ways. Students can take part in online surveys for collecting information and exploring it in a graphical way. 

3. Define Modeling.
What is
Modeling? Explain with suitable examples
Modeling is a computer program that attempts to display a real life system. It is a virtual version of something in a real world.
It is the representation of three dimensional objects on
the computer, using software designed for the purpose.
Examples:
·
War
Games and Disaster management in which computer offers a safe, inexpensive
means of creating or recreating events without the loss of life or property.
·
Computer
Models of a ship can be built. This can be viewed in 3D on the Computer with
a facility to Zoom and rotate in selected areas. This allows us to study
which Computer Model is best and then decide to build a real ship.
·
Computer
car model is used to investigate its engine life.
·
A
weather system model can be used to predict storms.


4. Define Simulation.
What is Simulation? Explain with suitable examples
Simulation is the technique of studying the behavior of a real world system by building a computer version of it. The use of a simulator also begins with building a Computer Model of a Real life system. One or more Variable of the Model is changed so that we can study its effect.
Simulation can be used to show the
eventual real effects of alternative conditions and courses of action in a
particular system.
Examples
·
Testing
of Explosive materials
·
Simulation
of Nuclear explosion
·
Pilot
training system
·
Games
of War, Racing, etc..
·
The
laws of physics relating to fluid dynamics can be programmed in the Model of
a ship. The user can then change variables such as speed or weight of the
ship and study the stability of the ship under different situations.


5. Compare modeling and
simulation.
Differences:
Similarities:
(A) Both computer modeling and simulations are computer applications which represent a real world or imaginary system. (B) Both computer modeling and simulations help designers to save time and money. 

6. Explain the benefits of
Modeling and Simulation.
·
Since
both modeling and simulation involves building Computer Models, rather than
real ones, they result in a huge savings in cost.
·
Modeling
and Simulations are cheaper, faster and easier than making and testing
different real life models.
·
It
can be used at any time and tested for number of times.
·
It
is fast, easy to use and improves the efficiency of the user.
·
It
has having many different aspects or features and is flexible and dynamic.
