Little do we realise it, but one of the finest laboratories exists in each and every one of our homes! The kitchen, where your parents prepare your meals – and hopefully you do too – is a live lab with a host of “ingredients” (in chemistry, we call them “chemicals”!) to prepare what your tongue and nose like most. The act of cooking is a marvellous lesson in biology and chemistry, with physical and chemical changes literally happening under your nose, as you convert plant and animal products into something tasty and nutritious. The kitchen is also filled with all kinds of magic ingredients: chemicals that are salts, acids, bases, indicators, and what not!
In this Theme of 3 Open TACtivities, we will delve into this marvellous home-Lab by discovering how turmeric is a lovely acid-base indicator; see how you can make a fire extinguisher with things that you eat; and even use our favourite humble table salt to make a base with the help of a simple AA cell! Materials in the kitchen will never cease to amaze you: each has its use and many are essentially simple chemicals that can be used for a host of experiments!
