Models of scientific objects are needed

-  By Maricar B. Capurcos, Teacher II David Moises Memorial High School, Balit, Mambusao, Capiz

A s ci e nti f i c mode l represents an object or concept related to science. Its three main types are physical, mathematic­al, and conceptual. However, it is very likely that it would not be the exact replica of an object.

Not every student can have the time to use a microscope especially if there is a lot of them and there is only a few of the microscope­s available and functionin­g.

What if they need to see what an atom looks like and they would have to know its exact features but it is too small for them to see these features?

T h i s i s w h e n m a k i n g scientific models come in. We can make a physical model of an atom and its different parts through using styrofoam.

People might question the use of styrofoam when an atom can be visually represente­d through a picture on a book or a video. Well, there are people who learn through being able to physically exert effort to remember something like touching a replica resembling the said atom and pair that with trying to remember the different parts through rememberin­g what they see and saying it repeatedly. In simpler terms, they learn better by using their hands.

Another use of scientific m o d e l i n g i s u s i n g a mathematic­al representa­tion of the concept. Some might say that speed is about being fast or slow when it can be represente­d as something equivalent to the quotient of distance over time or the time that it takes to cover a particular distance or when things like the free fall speed of gravity per second is mentioned.

The conceptual model is about using concepts to describe something like how animals are grouped together because of certain physical features that they have in common.

There are times that our own understand­ing of things is not enough to teach the students, so we need the rely on scientific models to help us get the job done.

Before we resort to fancier means of teaching such as going to the museums, exhibits, question and answer with the experts, and using computers, we need to consider what models we can use to help us discuss the lesson so we can save ourselves time and effort as well as spare ourselves from an increased likelihood of danger if we go on location. There are times that the best solutions are the simpler ones or the ones that are already there, already accessible, something that is a paragraph or sentence away. ( Paid article)
