Topic: What are the advantages and disadvantages of setting up a civilization near bodies of water. (Rivers, lakes, seas, e.t.c.)
There are both advantages for setting up a civilization near water and disadvantages. I think the biggest advantage of setting up a civilization near bodies of water is that you have water to drink. Another advantages is that you can have clean clothes by washing them in the water. There are lots of more creative and helpful things you can use with water. Some more advantages are that you can use the water to grow crops and you could also catch fish and eat it or trade it. Trading is a advantage for living near bodies of water because you could trade it for things that are hard to get around bodies of water, for example clothing, wood, meat, and more. Another advantage is that you can use if to transport, examples are using a row boat.
On the other side, the disadvantage is that if there’s a natural disaster that involves water like tsunami, typhoon, flood, and more. People will have a hard time during the natural disaster and after the disaster. Also people will have a hard time repairing after the disaster, and during the disaster, they have to protect themselves from the bodies of water. In example if all the bodies of water joins the civilization is more likely to flood the civilization. But when the place flood, houses will be destroyed, some people will eventually die and building , plants will be destroy too. It would take a lot of work to rebuilt the progress of the civilization and to plant back all the trees. This is a huge disadvantage since the rebuilding takes a lot of time and energy. In conclusion, there are both disadvantages and advantages of building a civilization near bodies of water. An example is that you can easily get food and water but it would eventually flood heavily some day.
How do(es) the evaporation of how slow or fast affect the size of the evaporated Copper Sulfate crystals?
If the evaporation is fast,
then the Copper Sulfate will evaporate and make bigger crystals.
I think that is the evaporation is fast the copper sulfate will evaporate and make bigger crystals, because when burner is on a higher level the Copper Sulfate with the salt will saturate faster and leave behind only copper sulfate salt. I think this because salt does dissolve in water and because when salt is put in water the atoms of the salt will be pulled away from each other but on the other hand if the water is taken away the atoms will rejoin. And they will rejoin faster in boiling water. In conclusion I think that fast evaporation will make bigger crystals. Variables:
||Method of Management and/or Measurement
||Different burner’s level of hotness
||by the setting (ex. 1, 2, 6)
||How slow or fast evaporation is depending on the burner’s setting
||1. Same size beaker
||Small size beaker
||2. Same burner
||Butterfly (Company’s name) Burner
||3. Same amount of Copper Sulfate
Include a detailed list of materials needed to carry out the experiment.
|1.) Small Beakers
|2.) Copper Sulfate
Include an easy-to-follow, step-by-step, set of instructions repeating the experiment.
- Take 2 small size beakers and fill both of them with Copper Sulfate each with 20 ml
- Put the first one on the burner with setting 1 until fully saturated
- Put the second on the burner with setting 6 until fully saturated
- Take out 1 microscope and look one at one fully saturated copper sulfate first
- Record which one is bigger and which one is smaller
In conclusion my hypothesis was inconclusive. This is because it took too long for the slow setting burner took too long. Which means that my hypothesis was rejected.
I learned from this lab that you should put less copper sulfate because it takes too long for the slow setting burner to saturate the copper sulfate. So next time I would put 10 ml of copper sulfate instead of 20
In math we had an assignment to choose a subject and draw a scale drawing of it. I chose the Eiffel tower because it is somewhere I really wanted to go to. I also chose this subject because it is a beautiful place and I thought it would be cool to draw a scale drawing of it. The math I needed to use was scale factor, measurement conversions including meters to centimeters. I also used multiplication, division, and measurement. Something that was challenging for me was finding the scale factor. I still worked through the challenges by asking a few questions and trying to do the best I can by searching the definition, using paper and pencil, and more.
