ALKALINE EARTH METALS what are alkaline earth metals? Alkaline earth metals are elements that are in the second group of the periodic table. the elements have two electrons on the outermost shell. the elements include Beryllium‚ magnesseum‚ calcium‚strontium‚ barium and Radium.The alkaline earth metals are all silvercolored and soft‚ and have relatively low densities‚ melting points‚ and boiling points. In chemical terms‚ all of the alkaline metals react with the halogens to form the alkaline earth metal halides

Osteoporosis is a bone disease in which the bones become very brittle and weak. Even a little cough could fracture your bone. Causes: when you’re in your younger ages you constantly make new bone how much you store when you reach your peak can determine whether or not you develop osteoporosis. Risk factors of this disease are: • Your Sex‚ in which women are most likely to get it than men. • Your age‚ as you get older your body stops making “new bone”‚ so you will have a greater chance in getting

Title: Determination of Water Hardness Using a Titrator Purpose: To become familiar with the concept of water hardness‚ practice a titration technique using a titrator‚ and determine the hardness of the local water supply. Procedure: 1. Gather the test tube holder‚ small stopcock‚ 10-mL syringe (titrator)‚ and 2 thick textbooks and the LabPaq box or 5-6 thick textbooks. 2. Remove the plunger from the titrator and place it back in your LabPaq box. 3. Attach the stopcock to the tip of

gain in order to live a healthier‚ happier life. Osteoporosis & Strength Gain 101 1. What Is Osteoporosis? Your bones are a living tissue. A certain amount of bone is always being broken down and reformed‚ in order to help the body balance its calcium levels. Normally‚ these two processes happen at the same speed‚ so there’s no overall change in bone mass. When a person develops osteoporosis‚ their bone tissue is breaking down faster than it can be reformed‚ so the bones start become brittle and

How does the Amount of CO2 Affect the Rate of Photosynthesis? There are a number of variables that can affect the photosynthesis rate of Canadian water weed (Elodea). They are as follows:  The amount of light: an increased light level increases the rate of photosynthesis to a certain point where at another factor limits the photosynthesis rate.  The temperature: Increased temperature increases the rate of photosynthesis to a certain temperature‚ after which‚ essential enzymes

Build a Fizz-Inflator Purpose of the project: * To know if water temperature affect how fast the balloon fills up. * To know if the size of the bottle affect how much the balloon fills. * To know if the amount the balloon fills-up can be controlled by the amount of vinegar or baking soda. Materials: * 1 small empty plastic soda or water bottle * ½ cup of vinegar * Small balloon * Baking soda * Funnel or piece of paper Hypothesis: * Yes‚ the higher the temperature

LIGHT IN PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place
