What? That sounds insane, but remember there is a load of crazy stuff in science that we can learn and enjoy from. I do not mean burning your money is fun, neither I would give in to the challenge if I am not confident I could actually have it back in exactly the same condition as it should be. You can practice this using ordinary white paper or filter paper cut into note-like sizes, that is to build up your confidence that it truly works. So, have fun and burn your money away. (more…)

As much as possible, science teachers would want to do activities in the class, which are exciting but less expensive. Especially when the kids are asked to bring the materials needed and turned out to be difficult to find or too much for the wallet, the thrill to do it would eventually fade.
There are many lava lamps available in the market but why not make your own and use of materials that one can easily grab in the cupboard or take out from the medicine drawer or buy from the nearest supermarket. Today I am sharing to you how to make a LAVA LAMP which I have done myself several times in science club activities or classroom demonstrations. (more…)

One of the most challenging tasks of a science teacher in a chemistry class is how to show that gases exist and it can be collected from simple reactions. Most common amongst these gases are OXYGEN, HYDROGEN, and CARBON DIOXIDE.
Yet there is a simple activity that could be done as a demo or class experiment to confirm those scientific explanation about acid-metal reaction. Be sure the materials are readily available in your laboratory. There are other processes to produce these gases but these are the ones helpful and practical in a school setting. (more…)

Recently, I talked about demonstrating firework effects using common salt compounds available in our chemistry laboratory. These compounds can also be used to make other exciting science activities like the COLOURFUL CRYSTAL GARDEN.
This is a simple, but exciting practical/demo that teachers can do in the laboratory. Again, just be careful with the salt compounds for they maybe corrosive, irritant, or toxic. Before you start, you need to secure the following things: (more…)
