compounds with the Bunsen burner and also by mixing compounds in the twenty four well plate. The experiment found that the liquid compounds reacted to form milky liquids. Also that the heated solids caused condensation that put the fire on the splints out. The experiment could have been flawed due to measurements.

the tube. Reaction 3- My hypothesis for reaction 3 is that the moistened litmus paper changes color. The odor will be a chemical odor that smells bad. The burning splint will be extinguished. Reaction 4- My hypothesis for reaction 4 is that adding hydrochloric acid to solid calcium carbonate produces bubbles maybe. When burning the splint is placed on the test tube‚ the flame is extinguished. Reaction 5- My hypothesis for reaction 5 is that mozzy zinc in the test tube will make smoke come out of

About 1g of the solid was placed in a dry test tube and the test tube and its contents was heated in a burner‚ gently at first the strongly. During the heating the test tube was sloping slightly downwards. 2. Gases were tested and evolved with moist blue and red litmus and with a glowing splint 3. The results were tabulated noting carefully all that happens to the compound when it

categories of bone fracturing‚ they are: 1. Hairline fracture- a thin small stress fracture often occurring in the leg. In the case of this injury‚ a splint and cast are the only medical means necessary for repair. 2. Greenstick fracture- A thin fracture‚ often appearing in the bones of children‚ which are more flexible due to immaturity. A splint and cast is the sensible tactic for healing in this case‚ to keep the bone immobilized and protected. 3. Closed fracture- A fracture

until 1970 (Lieberman 531). So what did people do when the modern running shoe wasn’t around? More and more people have been asking themselves this very question. Injuries are almost unavoidable when running. Stress fractures‚ pulled muscles‚ shin splints‚ the list is endless. Every runner has experienced an injury at least once. Some injuries are nagging and can ruin peoples running career. Could it possibly be that the modern day running shoe is causing injuries in many athletes today? Humans

Several materials were needed for the conduction of this experiment. Bunsen burners were used to generate heat. The process also required elements in liquid state‚ LiCl‚ NaCl‚ KCl‚ CaCl2‚ SrCl2‚ CuCl2‚ BaCl2‚ nichrome wire(or remove a pre-soaked wood splint)‚ small test tubes for the metal ion solutions‚ safety goggles‚ and tabs to absorb the liquids. Containers were labeled to identify each element. Observations were recorded on a data table. Safety: You must wear your goggles at all times

CLUBFOOT Clubfoot is defined as a congenital foot deformity characterized by a kidney shaped foot that turns inward and points down. The forefoot is curved inward‚ the heel is bent inward‚ and the ankle is fixed in planter flexion with the toes pointing down. Shortened tendons on the inside of the lower leg‚ together with abnormally shaped bones that restrict movement outwards cause the foot to turn inwards. A tightened achilles tendon causes the foot to point downwards. The medical term
