At Miracle Learning Centre, we always try to make our lessons fun and interesting for our students. For that, we always look forward to implementing new teaching techniques in our classes. We teach with the help of various fun facts, videos, illustrations, models, games, etc. They are all focused to provide excitement and enriching knowledge for the students at each step.
Hi, and welcome back to your Science Tuition. We know how much of a science addict you are, and we are here to make sure you get your daily dose of science.
So in today’s Science Tuition, we are going to give you some of the chemistry facts which will leave you mind-boggling.
- We know all the metals are silvery. But do you know what the exceptions are? Well, there are only two non-silvery metals, and they are gold and copper.
Here are some of gold’s physical properties. Gold is a soft metal with a number of interesting physical properties. Gold is a heavy metal (density 19.3 g cm-3) and one gram of gold can be hammered out into a thin sheet of gold a metre in area. Gold is both malleable and ductile. Malleable means it can be made into sheets. Ductile means it can be made into wires.
- We are known to the fact that our pencils contain lead and you know what lead is. But did you know the human body is capable of producing the lead for about 9,000 pencils because we have enough carbon in our body? Well, now you do.
The cap covering the cork on most bottles of wine used to contain lead. Lead capsules were dangerous, and most agree that completely removing a lead capsule and wiping the top of the bottle before serving can help avoid possible lead contamination. Nowadays, most bottles have foil, tin-coated and plastic capsules, or even with none at all. Lead poisoning is a dangerous thing. There are many negative side effects that lead can cause. Leaded petrol is also banned in our modern day.
- Do you know how the earth’s oxygen is produced? Well, the first and most obvious answer that you may come up with is rainforests but that is not true. It is the marine organisms! Plankton, seaweed and other photosynthesizers produce over half of the world’s oxygen.
Well, we hope you were baffled by today’s class in Science Tuition. We wish to see you soon, till then stay tuned.
