Science Experiments

Because of capillary action, the water flows or “walks” up and over the paper towels right into the empty cup. The empty cup fills up with water until the water levels of every one of the cups are equal. The original colors will mix creating a new color.  

Dissection of a cow's eye can explore the anatomical layers from the outside in.   This includes: Optic Nerve, Choroid with tapetum lucidum, Iris, Pupil, Sclera, Cornea, the Retina, Lens, and the Vitreous Humor.

Distillation of oranges allows separation of the components using a method to vaporize and remove water from the liquid.   Heating up the liquid allows the young scientist to observe: color, aroma and flavor, what is Volatile(turns to gas) vs. Non-Volatile (remains a liquid or solid).

 As the food coloring is drawn up the paper towel, the different pigments separate. The reason is the pigments are different weights, travel at different speeds, and thus end up in different places. Chromatography is the technique of separating mixtures.
