WATER CONSERVATION Water conservation encompasses the policies‚ strategies and activities to manage fresh water as a sustainable resource to protect the water environment and to meet current and future human demand. Population‚ household size and growth and affluence all affect how much water is used. Factors such as climate change will increase pressures on natural water resources especially in manufacturing and agricultural irrigation. The goals of water conservation efforts include as follows:

sodium hydroxide solution. This will make it possible to measure the depth to which the color has penetrated and will demonstrate the relationship between diffusion and volume. Materials: -agar -scalpel -spoon -two large beakers -ruler -timer -Potassium manganate (K2MnO4 ) -Hydrogen chloride (HCl) Methods: -Make two trays of Agar Gelatin. One pure and one dyed pink. -Use the scalpel to cut three agar cubes of each tray: a 3cm cube‚ a 2cm cube and a 1cm cube (total of six cubes).

until we saw that the bottom of the water line reached closely to 1 mL. Next‚ we took the four tubes with the scoop of yeast and added to each the corresponding 1 mL of water from tubes A-D. As soon as each tube had the 1 mL of water we put the timer for exactly ten minutes and waited for the yeast or our enzyme to “activate”. During the ten minutes‚ my partner and I started preparing our 0%‚ 25%‚ 50% and our 100% Hydrogen Peroxide solution.

Motivating an organization’s employees is not amongst the easiest of tasks for a manager to accomplish. Even more challenging is motivating part-time employees whom are usually forgotten and ignored by the organization (Inman & Enz‚ 1995‚ p. 1). According to Statistics Canada‚ nearly 19% of the workforce constitutes of contingency workers who are not being utilized to their full potential (Statistics Canada‚ 2008). It is noticed that the number of contingency workers is almost one fifth of the workforce

Microwave oven saves time . The important benefit of a microwave oven is the ’time efficiency’. As compared to the traditional methods of cooking‚ microwave ovens take very little time to cook. A microwave oven has a timer which enables us to set the time for cooking food. When timer runs out‚ the oven turns off automatically. Different times are set to cook different types of food items. For instance water can get boiled in one minute; cookies will take longer time to bake. Easy to clean .Microwave

Problem: Which hand can tolerate cold better: dominant or nondominant? Background: Handedness is dominance of either your right or left hand over the other‚ which means that generally one hand is better at motor skills than the other. It involves the coordination of large muscles carrying out smooth motions‚ such as throwing a ball. These actions use many neurons‚ and require concentration. The left side of the brain controls the right hand‚and the right side of the brain controls the left hand.
