Transcript of Science Experiment
2) Place a tripod on op of the bunsen burner.
3) lace a gauze mat on op of the tripod.
4) Get the 150ml beaker and put the 50g mass into it
5) Get the 400ml beaker and out the 150ml beaker in the middle.
6) pour 100ml of the dirty water into the 400ml beaker.
7) Carefully place the watch glass on top of the 400ml beaker so the middle of the glass is on top of the small beaker.
8) Make sure the bunsen burner's nozzle isn't directly under the small beaker, and then turn it on.
9) Bring the water to a boil and watch it evaporate.
10) After a while, turn off the bunsen and wait for the beakers to cool before picking them up. Description - while doing the experiment The water is boiling and the watch glass is all steamy
Water is starting to form on the watch glass. It is really boiling. Steam is coming out of the beaker
After we turned the bunsen off, the water continued to boil and evaporate.
The water in the 400ml beaker is yellow and dirty and it smells like oil.
The water in the 150ml beaker is a bit cleaner than the other one, but its still dirty. Possibility : The water in the beakers are dirtier than the few water droplets left on the watchglass. How did our equipment purify our water? It purified the water because when you boil a liquid up, it evaporates. So when we put the Bunsen under the beakers and boiled the water, it evaporated. The watch glass stopped the steam from escaping. When the gas hit the wact glass it turned into water. The watch glass' bump in the centre made the water droplets drip straight down into the middle of the beaker. Would this be a good method to use for a city full of people? Explain your answer. This wouldn't be a good method because it takes time to evaporate. People use a ot of water so then there might not be enough water for everyone because the evaporation process is slow. Introduction Results Method Equipment In this experiment, we are going to see if we can turn a dirty sample of water into a clean sample of water. We are going to use distillation. just facts : The chemicals that are added to Sydney's drinking water are Chlorine, Fluoride, and Ammonia.
Chlorine is added to the water to kill any of the harmful bacteria in it To see if we can turn dirty water
into clean water by boiling it in
the distillation process. I think that we may be able to make
a clean sample of water using
distillation. 1x Watchglass
1x 400mL Beaker
1x 150mL Beaker
1x 50g Mass
1x Bunsen Burner
1x Gauze Mat
100ml Of Polluted Water I think that the water in the beaker is dirtier because I didn't evaporate all the water in the beaker. Because all the water did not evaporate, there would still be some dirty water left in the beaker. Therefore, when the clean water drops back down, it falls into the dirty water, making it ( once again ) dirty. PUZZLE BUSTED Discussion Suggest how we could speed up the process. We could speed up the process by putting more water into a bigger container and use a bigger and hotter fire Experiment - Purifying our water with the distillation process. COMPLETE By Beatrice Tran
