1. Medium Priority
1.1. Bunsen Burner
2. Sources
2.1. Substances Collected individually
2.1.1. Water and salt
2.1.2. Water obtained from broken water pipes. Water is contaminated with salt and sand.
3. Apparatus Used
3.1. Low Priority
4. Filtration
4.1. Sub Idea 1
4.2. Sub Idea 2
5. Aim: As an aspiring science researcher, you are the given the challenge to purify the sample of water that the Haiyan survivors have collected from various sources. In order to help the survivors to bounce back in their economic aspect, you are to collect some important substances that the survivors can sell to earn a living or use for their own consumptions.
6. Concave dish is made to hold the polluted water
7. Procedure
7.1. 1. Cut a piece of aluminium foil about 30 cm long and fold it to a concave dish.
7.2. 2. Position the cloth bag above the aluminium dish. The cloth bag will act as a filter where the the large sand particles will not pass through the small holes of the bag.
7.2.1. We want to filter out the sand particles so the end result collected is a salt solution. salt solution is needed later
7.3. Cut another piece of aluminium foil and fold it to become a concave cover of the dish.
7.3.1. The concave cover allows the water vapour that is evaporated to condense and form water droplets
7.4. Place the cover above the dish
7.4.1. To increase the rate of evaporation and condense faster
