Raise awareness on water issues among your students by showing them what a precious resource it is. Though our Earth's surface has a significant amount of water, 1385 cubic kilometres, only 2.5 per cent of this is fresh water available for plants and humans. Preserving and conserving this available water are important issues. Encourage your students to share their views and ideas about how to conserve water. Culminate your assembly by launching a school project.

The World's Water
Begin your school assembly with an activity that visually shows how much available water there is on the Earth and how scarce a resource it is. Start with all of your water inside of a large bucket to represent all of the earth's water. Take out a large bowl of water from the bucket to represent the available fresh water. Fill a large cup with water from the bowl to represent the fresh water available for plants and animals to use. Fill, as a final step, a smaller glass to represent the amount of water humans can use. Choose an appropriate medium for the size of your audience. Use a PowerPoint presentation with pictures. Use buckets and cups for a smaller audience.
Conserving Water Indoors
Ask the students what they do to conserve water in their own homes. Give some suggestions to start the discussion rolling. Turn the tap off when you brush your teeth, and turn it on only when you need it. Fill a bowl of water to rinse the dishes of soap instead of rinsing them under running water when hand washing dishes. Run dishwashers and washing machines only when they are full.
Conserving Water Outdoors
Wash your cars outside with a bucket of water instead of using the hose. Water your lawn or grass with a sprinkler for 10 minutes every other day. Make sure that the water from the sprinkler is for the grass only and that the water does not go on to the sidewalks or cement. Use brooms to wash your driveways or sidewalks instead of the hose. Turn the hose tap off after every use so that water does not drip from the hose.
Preserving Our Water
Encourage students to get active and learn about different ways to improve and preserve the water in your areas. Encourage the use of alternative cleaning products like vinegar, lemon juice and baking soda. Liaise with a local recycling plant to discuss what types of products can be recycled to keep them out of the waterways. Discuss suggestions that your students may have for a school project on clean water. Give examples such as raising money to build a well, purchase rain tanks or buckets for families in developing countries.
