Chemistry. chemistry: ( kĕm ' ĭ-strē ) n. The study of the composition, structure, properties, and reactions of matter (everything that makes up the universe). Standards. Physical Sciences: Elements & their combinations account for all the varied types of matter.

How an element looks, feels, smells, sounds,
or tastes that includes:
(e.g.: H20 = 32o F or 0o C Freezing Point).
Freezing Point =32oF or 0oC
Boiling Point = 212oF or 100oC
Chemistry is exciting for students and many times the matter used in the elementary classroom may be found at home. Please advise students that these experiments have been carefully created for their health (reactions and new products are known).
PLEASE DO NOT MIX MATTER AT HOME WITHOUT AN ADULT’S SUPERVISION AND A RECIPE FROM A REPUTABLE SOURCE.
Many families do not know that ammonia mixed with Clorox releases deadly gas. Also, many glues when mixed with salts release deadly gas. The “Flubber” experiment – Boraxo + Elmer’s Glue - should not be used with other glues.
Fructose - the main sugar in fruit, Sucrose, also known as "table sugar," lactose - found in milk, and so on.
The suffix – ose means “full of”
Glucose and fructose are monosaccharide or one “sugars”. Lactose, sucrose and maltose are disaccharides - containing two “sugars”. These are called simple carbohydrates and they enter our blood stream at about 30 cal/min.
Physical property: they all taste sweet. Glucose is colorless. When you look at a "Nutrition Facts" label on a food package and see "Sugars" under the "Carbohydrates" section of the label, these simple sugars are what the label is talking about.
Complex carbohydrates (starches) made up of “chains of glucose molecules”. Starches are the way plants store energy. Most grains (wheat, corn, oats, rice) and vegetables like potatoes are high in starch. Your digestive system breaks these carbohydrates has to back down these molecules before the glucose can enter your bloodstream. This takes time. They enter the blood stream at 2 calories per minute.
Plants make starches through a process called photosynthesis. They take in CO2 through their leaves and H2O. Chlorophyll and sunlight create a chemical reaction that releases O2 andcreates sugar.
