Is Science important? The answer lies right in front of our eyes. Think about a world without technology. No computers, no cars. No vaccines or cures for diseases. Life would be joyless and extremely hard. It was not long ago that this was the case. How ever, now with science on our side it’s a whole new story.
The scientific information we studied in Unit 1 – “Setting the Standards” is important to everyone. We have learned about identifying Substances using properties, Safety around us (WHMIS) and Physical and Chemical changes. Scientific research has helped us establish many different physical and chemical properties. Appearance, Texture, Colour, Solubility, Combustibility and taste are just a few to name. These have all been discovered through scientific research and experiments. These properties help us describe and identify matter when required. They can also be used to describe and differentiate substances. That is not all; scientific research has helped us describe the effects of these different substances. WHMIS symbols have been created from scientific research to represent caution or a hazard in a substance. Without these symbols, we could seriously hurt our selves when handling substances not identified.
Materials in our daily lives need to be identified for our safety. Who knows when you’ll touch something highly corrosive or toxic? That just might be the end of your repertory system! Ever wondered how and why these substances change? Science has the answer. There are two different types of matter changes. One is called Physical change and the other is called Chemical change. In a physical change, the substance remains the same but it changes its state or form. An example of this would be water freezing into ice. The substance has remained the same but its state has changed. A chemical change is when the substance changes into one or more different substances with different properties. The substance can not be changed back to how it started. All of this information is discovered through scientific research. Think about how much a loss it would be to ignore this info by thinking Science is a waste.
Without science, we would not advance in our technology. The thermometers we use to find the temperature of substances or our selves would not have been created. We would be struggling. We use diverse machines to measure and investigate different physical and chemical properties. Microscopes, heating devices and stylus’s are all used to find physical properties of substances. We use computers to predict what we believe will happen. Using computers, labeling of different WHMIS symbols is also done. These labels tell us what precautions to take before using the substance. Remember this is for OUR safety. So without science, we would not be safe at all.
