Development of a Science Demonstration Laboratory in National University of Singapore

Science demonstrations are a good way of promoting, teaching and learning science. This is provided that there exists carefully crafted “software” and communication methods to go along with the hardware. During the past few years, we have developed a Science Demonstration Laboratory at NUS aiming to play an active role in science outreach, science communication and science education. Our approach has evolved from an initial “show-and-tell” model to a more engaging “minds-on” approach where participants are consistently required to make predictions of the outcomes of scientific phenomena before witnessing the demonstrations. We also learnt that the education and development of talented science educators and communicators are crucial to ensure and project the effectiveness of a “hands-on”, “minds-on” approach to science education.

The Neon Fruit Illusion: A Fresh Recipe for Colour Science Demonstrations

At this year’s European Conference on Visual Perception, we debuted a novel colour science demonstration—and visual illusion—for the Un mare di illusioni exhibition. Under carefully curated lighting conditions, cycling through different illuminant spectra, certain fruits and vegetables appear to glow and dim in an unchanging environment. Encouraged by the positive reactions it received, and the numerous and specific questions from conference delegates, we here describe what this illusion is, why we believe it may work, and how this particular low-cost setup may be assembled and demonstrated for the amazement of your friends, students, and members of the public.

Planning of Botanical Garden on Saline-Alkali Soil

The planning of Botanical Garden on Saline-alkali Soil has important forward-looking and strategic significance for urban in saline-alkali soil district to explore the core value of saline land as a regional land resources. The core principles include the ecological priority, scientific repair, science demonstration, rational use and sustainable development.
