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…)

Many practical classroom activities could be carried out, when teaching the concepts of conduction, convection, and radiation. These are simple yet relevant, and would allow students to understand the topic easily. The concept has to be taught in the first 15 minutes of the 1-hour class and then proceed to show some of these demos.
The teacher prepares the materials needed and see to it that safety precautions are observed.
- Prepare three different rods such copper, glass, and iron (or whatever is readily available, except of course plastic rods).
- Place them on a tripod and fix a small nail near one end of each rod using candle wax or Vaseline as ‘glue’. (Make sure the rods are not touching each other).
- Using a bunsen burner, heat the other ends of the rods evenly.
- Record the time it takes for each nail to drop off from the respective rods? (more…)
Are you still struggling to reconcile the disparity between Darwin’s evolution theory and the Divine Creation? Perhaps most of us are recurrently, mystified about the feasibility of time travel and time machines. How about the existence of parallel universes, do you find it amazing or rather irrational? Still interested around alien invasion or you may be more engrossed reflecting the issues of global warming and its menace that we are already living through. Plus, the revolution of technology that has affected every single aspect of our life, we may continue to ask these questions: Why do we have to learn Science? Is there an end to Science? (more…)

This activity investigates the rule of reflection, which focuses on obtaining, collecting, and considering evidence. The students should learn and remember the basic terms that are associated with the law of reflection.
When you look in a mirror, you can see a reflection of yourself. If you look at texts on the newspapers or magazines, they appear to be reversed, which is the way light is reflected by a mirror. How can we investigate this phenomenon? What is reflection? What is the law of reflection? (more…)

An activity that can be done as a class experiment. Just make sure materials and equipment are available for the students. If not readily accessible in your school, ask groups to bring in materials.
This activity can be used when discussing about the importance of water. As a springboard of the topic, prepare pictures or powerpoint slides on water pollution, water scarcity in different parts of the world, sources of water, and etc. When it rains, water penetrates into the ground and as it passes through it, the water is filtered by the rocks, and sand, and soil, and eventually comes out as clean water at a spring or wells.
