Benefits
Interactive Experiments
So much can be learned when we study opal: The way light changes as it passes through a certain structure. How structure can be the only difference between a piece of schoolroom chalk, a pearl and an abalone shell. Duplicating the process by which opal is built, can lead to a better understanding of building nanostructures to save lives.
Light Diffraction
Light diffraction and refraction are phenomena that occur to light when it meets an obstacle. Diffraction is light bending slightly around an object or passes through a small opening. It is the phenomenon that occurs when we look at a CD under a light. The closely spaced tracks on the disc create a diffraction grating. Refraction occurs in the case of opal, when diffracted light changes directions many times while within the opal structure. Bragg’s law of Diffraction explains the exhibit of spectral colors.
Science Curriculum
Interactive curriculum keeps children interested. There is no chance of falling asleep at their desk and no chance for their mind to wander when their hands are at work. Interactive class work is fun and interesting, engaging multi-sensory stimulation for learning
Opal is formed in the earth
Opal is formed in the earth when a rich solution of silica and water filter through the Earth’s layers and the fill voids and hollows within. Over time, the silica settles into the bottom of the voids assembling into a very unique structure that can manipulate light.
