CAT - Measuring the pH of common household substances 1. Predict the pH value of substances & estimate the pH value by using the universal indicator. 2. Use the indicator to identify acidic‚ basic‚ and neutral substances found in any home 3. Classify household items as acids and bases 4. Collect organise and analyse results in tables and graphs (if necessary) 5. Analyse results and explain the reason the substances have the pH obtained. Aim – To use a universal

pollution and preserving the resources. In many cases the important sector of public health has been left alone when major upgrading projects improved the water supply systems in many countries and provinces. This basically ignored the downstream effect of improved water supply‚ that of increased discharges into rivers or aquifers. Two reasons appear to be the major cause for that: firstly‚ wastewater collection and treatment is costly and their benefit often hard to show; and secondly‚ even if low-cost

PLANTS AND HUMAN BEINGS Plants and humans are living things that constitute part of the environment. These two depend on each other for their survival. But as plants can live without humans‚ humans can not live for long without plants and this essay explains why this is possible. Plants have the capability to build up organic substances they need from inorganic substances. They only need carbon dioxide‚ water and salts to make their essential substances. Glucose for example is produced from these
