Perfect as the wing of a bird may be, it will never enable the bird to fly if unsupported by the air. Facts are the air of science. Without them a man of science can never rise. In science the credit goes to the man who convinces the world, not the man to whom the idea first occurs. It may set limits to knowledge, but should not set limits to imagination.

We attended the last Science Fair held in CABEIHM at Batangas State University, Main Campus. When I enter the Science Fair together with my friends, I’ve seen the different activity. I felt the curiosity behind the “Colored Shadows and Van de Graff Generator”. Colored Shadows shows that not all shadow that we can see is black. We can learn about human color perception by using colored lights to make additive color mixtures. In Van de Graff Generator which makes our hair stand on end. The device looks like a big aluminum ball mounted on a pedestal, and you can see its effect in the accompanying image. And also the brain shocking “finger Tingle”. In this, electricity is generally invisible, inaudible, tasteless, and odorless. We normally have no way of sensing its presence except with some kind of instrument. This exhibit allows us to experience the flow of electricity directly as well as through the visual indication of a meter. We hope that this experience tends to make one more appreciative of indications one encounters on meters in this exhibit.

The investigation and study could lead to an interest and passion which we can carry on for many years. Discovery is fun and exciting, we learned more about science and the scientific method, we able to exercise and build upon our research techniques, build self-confidence, learned how to follow step-by-step directions, learned about cause and effect and how things really work.
