05 Sep Science Tuition
There can be no learning without fun. Science is all about having fun. Why? Well, we all have had various questions in our mind out of curiosity during our early stages like why is the sky blue? Why should we drink water? Why everything that goes up, comes down? And many more. Well, all of these are answered and explained by Science. Students often feel encouraged and excited to learn new things when they are taught using various modern teaching models. At Miracle Learning Centre, we teach our students by using various modern methods in which we implement various video lectures, illustrations, games, facts, models, etc. This makes them learn difficult concepts of Science easily and also makes them score more grades with lesser efforts.
If you feel difficulties to understand Science and feel like it is not your cup of tea then we would like to invite you to join our innovative classes of secondary science tuition, primary science tuition, IP science tuition in Singapore.
Hi and welcome back to your Science Tuition. We are glad to have such inquisitive students like you. Hope you are learning and practicing your everyday science.
Today, in your Science Tuition we are exploring the element called chlorine. As we all know chlorine is denoted with the symbol Cl and has the atomic number 17, so let’s start with our digging:
