SCIENCE HOMEWORK SKILL BUILDER SEPARATING AND CONTROLLING VARIABLES SCIENTISTS PAY CLOSE ATTENTION TO CONTROLS, DEPENDENT VARIABLES AND INDEPENDENT VARIABLES WHEN THEY DESIGN EXPERIMENTS. DO THE CHAPTER 3 SKILL ACTIVITY ON PAGE 844 TO LEARN HOW TO IDENTIFY CONTROLS AND VARIABLES. SUPPOSE YOU DISAGREE WITH A FRIEND ABOUT WHICH SPORTS DRINK CONTAINS THE MOSTS FLAVORING SWEETENER AND OTHER DISSOLVED MATERIALS YOU CANNOT ACCURATELY FIND OUT BY TESTING EACH SPORTS DRINK BECAUSE EVERY INDIVIDUALS SENSE OF TASTE IS SLIGHTLY DIFFERENT TO SETTLE THE MATTER YO TRY TO FIND SOME METHOD OF TESTING THE SPORTS DRINKS THAT IS FAIR OR UNBIASED.

SCIENCE HOMEWORK A helium–neon laser or HeNe laser , is a type of gas laser whose gain medium consists of a mixture of 85% helium and 15% neon inside of a small bore capillary tube, usually excited by a DC electrical discharge . The best-known and most widely used HeNe laser operates at a wavelength of 632.8 nm, in the red part of the visible spectrum. Bronze is an alloy consisting primarily of copper , commonly with about 12% tin and often with the addition of other metals (such as aluminium , manganese , nickel or zinc ) and sometimes non-metals or metalloids such as arsenic , phosphorus or silicon . These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness, ductility , or machinability. An ice cube is a small, roughly cube -shaped piece of...

FINAL TERM
THE NATURE OF MATTER ? All atoms have the same number of protons (positively charged) and electrons (negatively charged). Therefore all atoms have a neutral charge (the positive and negative charges cancel each other). Most atoms have approximately the same number of neutrons as they do protons or electrons, although this is not necessary, and the number of neutrons does not affect the identity of the element. WHAT IS SCIENCE ? Science (from Latin scientia , meaning "knowledge") [1] [2] :58 is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe . [a] Contemporary science is typically subdivided into the natural sciences , which study the material universe ; the social sciences , which study people and societies; and the formal sciences , which study logic and mathematics . The formal s...
