Investigative Question
What is effect of different purification methods on water using boiling, filtering and purification tablet?
Hypothesis
The more processes done to purify the water the better the water quality for example beaker 5
Apparatus
• 5 beakers/containers
• Filter paper
• Purification tablets
• Pot
• Dirty dam water
Method
1. First collect five containers or beakers. Fill them with 200ml dirty water from a dam.
2. Put a piece of filter paper on top of each beaker except the first beaker this is the one that you are not going to purify.
3. Put a purification Tablet In the second beaker
4. Take a pot filled with the 200ml of water and set it on the stove until it starts to boil.
5. Once boiled place the water into the third beaker.
6. Wait until the tablet had dissolved in the water.
7. Then test each beaker and record your results in the form of a table.

Safety Precautions
Do not drink the water before it has been purified
Make sure you are in a safe environment
Observation
It was noticed that the more things done to purify the water the clearer...
Put one water flea in a cavity slide and used filter paper to remove the excess water.
4. Pour about 300mL of tap water into the beaker. Set up a hot-water bath using a hot plate, retort stand, and thermometer clamp. Alternatively, use a Bunsen burner, retort stand, ring clamp, thermometer clamp, and wire gauze.
§ Pour water from the kettle into the beaker until it is half full and
The water will be heated to 40°C using a kettle. 3. When the water reaches 40°C it will be poured into a test tube. 4. A thermometer will be placed in the test tube to measure the amount of heat lost.
As the bottled water becomes more popular, people prefer to drink bottle water over tap water. According to them, it has a better quality and taste. Unfortunately, people are being fooled by the water industries. The “purified” water, as its label, comes from municipal reserves. This research will discuss:
Remove the metal object from the first beaker and insert it into the second one.
Plan 1. Collect 4 different sized beakers 2. Boil some water in the kettle 3. Pour 50ml into each beaker 4. After 1 minute check temperature 5.
In a Styrofoam cup, record the temperature of the 200 ml of cold water. This is 200 g of water, as the density of water is 1 g/ml.
Comment on class result with respect to differences in filter types, differences in filter assemblies, and overall on the confidence you would have in using this type of sterilisation process in preparation of pharmaceutical products. List the factors that may cause contamination during filtration. (20 marks)
Rinse your beaker thoroughly to wash any excess powder. 12. Repeat steps 7-11 3 more times for reliability. To make sure the temperature still stays hot by continue heating the water a little bit using the hot plate. 13.
Fill another test tube with 200 mL of plain water and label it Negative Control.
2. In the large beaker, put water and boil it completely. After that, remove the beaker from heat. 3. Sample tubes (A-D) should be labeled and capped tightly.
The consumption of contaminated water can be dangerous for health reasons and several people have passed away from these water-borne diseases. Some of these diseases include Cholera, Typhoid, Dysentery, Giardiasis, and Malaria. These unfortunate diseases are currently the cause of numerous deaths, especially in small children. The availability of clean water can prevent many problems in low-income communities. The available resources for clean water are very rare, so these water sources need to pass through a process of water sanitation in order to just be sustainable to drink, “The world’s surface is made up of approximately 80% water, which is an indestructible substance.
Water plays such an important role in our daily lives. 70% of our body is composed of water. 70% of the earth surface is also made up of water, but out of the 70%, only 1/3 of water is consumable. In fact, this amount has been continuously to decrease as more and more industries began to pollute and damage the water. For example, many toxic chemicals may be released into the water thus making the water impure. Such pollutions and damages lead the water to be contaminated and inconsumable as it may cause severe diseases. Water purification can remove all the unnecessary bacteria and viruses from the water that is hazardous for our health. Water purification may also improve the flavor and appearance of water. It removes the unpleasant odor. Therefore, water purification became one of the most useful and popular process used by people all over the world today. It is by far the most recommended and safest water treatment that is commonly used to purify damaged water into consumable water. Water purification provides us with safe, pure and clean water to consume and use.
Distilled water is popular and has been around for thousands of years. Distilled water is a form of purified water whether by the ways of the past or the technology of the present. This purified water is what we, as humans, mainly drink. "Water is a clear, odorless, tasteless liquid which is essential for most animal and plant life and is an excellent solvent for many substances" (National Center for Biotechnology Information, n.d.). Water is the most common and useful substance in the world.
