This report is almost comprehensive, but i notice a few vocab words missing that were in this chapter of the text book. There were a few spelling errors, but really it's a very good report. The examples are well chosen and helpfull, though perhaps there is a video of the distillation process that would be clearer than the photo.
rahim says: Good progress Waseem. I see some spelling errors that should be fixed for example you wrote "indepentend" instead of independent. You also mentioned that the gas molecules bounce off eachother and the container walls however in your drawing the molecules are not touching the walls of the container.

You cited our chem book so I was wondering why didn't you explain atom, element, molecule, compounds, mixtures (you know...the words in bold in the book), etc. What you did was skip to the "States of Matter" section WITHIN the "Classification of Matter section." So you kinda missed the other important concepts. I think that if you added those things it would make your module more comprehensive and kick ass. -Phat Posted 22:40, 3 Mar 2009 <form action="/index.php?title=Analytical_Chemistry/Quantifying_Nature/Classification_of_Matter&action=comment" method="post"></form> lduong says: A couple spelling errors, but other than that everything looks good. I loved your examples. It'll be helpful if you added the answers for the practice problems Katherine Williams says: Your images are very good at illustrating you point. However, the first diagram that you have is slightly confusing. You have the over arching subject of "all matter" but then have a sub- category of "matter". What is the difference between all matter and matter? Also, there are a few typos that make your page difficult to understand. You wrote in the introduction "In order to differentionated the state of matter..." I think you meant differentiate. Also, under the section of gas you wrote " it becomes into the gaseous state matter..." I think you mixed two thoughts of "it become a gaseous state of matter", and it turns into the gaseous state of matter". Also, when talking about liquid water, you said that the volume has to do with the bottom of the container. Don't the sides of the container have an affect as well?

I think another chart would be great to help show the break down of matter as described under the section "Classifying Matter." Also, you have an example for every mixture except colloidal mixtures. An example of a colloidal mixture is cow's milk. Also, your table of contents is a little awkward. Why are there dashes? Name those sections instead. When you are talking about the three states of matter, give examples outlining the importance of these states. What if water was a solid at room temperature? How would that change the world as we know it? |
1. Synopsis: This module is about matter. It gives information on the three main states of matter: solid, liquid, and gas. It also talks about substances and how it can form homogeneous and heterogeneous mixtures, and methods that could be used to separate these mixtures.
2. Keywords: matter (Google), states of matter (Google), solution (Google).
Note: your diagram on separating matter is similar to Figure 1-4 (p.6) in our textbook, but you did alter it a bit so it should be fine.
3. Review Details: The information in this module is very good, and the pictures really help the readers understand the module’s facts. However, I think that two of the module’s parts could be organized differently to make it easier for the readers to comprehend the topic. First, the first paragraph under “Classifying Matter” should be organized in terms of magnitude. Maybe go in the order of: 1) matter, 2) atoms, 3) electrons, neutrons, and protons. Then show how a group of atoms form molecules, which then forms compounds. The order does not really matter, but stick to either increasing magnitude or decreasing magnitude for better organization. Also, under “States of Matter,” I think it would be better if you talk about solids first, and gases last. Furthermore, I think it would be more useful if you add questions regarding solutions on top of questions regarding the states of matter, and also provide an answer key. Other than that, I like the information, pictures, and examples that you provided.
1. Synopsis:
This module talked about the components of matter, different classifications of matter, and different states of matter. It talked about how all matter is made from atoms ( electrons protons and neutrons), and it also distinguished between molecules and compounds. Then, the module talked about different substances (heterogenous, homogenous). Finally, the module discussed the three main states of matter (gas, liquid and solid)
2. Keywords:
Matter (Yahoo)- appears to be no copyrighting
liquid gas solid (Yahoo)- appears to be no copyrighting
classification of matter (Yahoo)- appears to be no copyrighting
The diagram with "all matter" on the top is extremely similar to the one in the book, I would change it more, or come up with an original idea that shows this classification process.
3. Review Details:
Mostly, the information is good and accurate but I would add a few things. When you talk about mixtures, you only talk about colloidal mixtures, so I would include the other two types that we learned about in lecture. Also, I feel like the module is a bit out of order, you may want to talk about solids, liquids, and gasses before you discuss things like mixtures and separation of mixtures. In the solids, liquids, and gases section, I feel like you were only talking about water as a solid, liquid, and gas. So maybe you shouldn't make that section so specific, because not all compounds freeze at 0 degrees C, for example. Lastly, the last bit of info about unusual states of matter is good to have at the end, and i dont think you need to go into it further, but maybe organize that section a bit because it kind of seemed jumbled with too long of sentences to it appears confusing to the reader. Other than that, you have some good, original pictures, and the info is helpful!

1. This article, using many examples, flowcharts, and pictures, describes and teaches how matter is classified. It begins with classifications of mixtures, then ends with states of matter. I really liked the pictures.
2. I think that this modules is ready to move on, it is very well organized.
3. It is a good length, the ideas are presented in good order, and the pictures are representative of what the article is talking about. I think that the images could be better formatted though, the spacing and sizes are irregular, and the left/right alternating justification is a bit jarring to read and connect back to the label or text. Also, references to Fahrenheit may be converted to Celsius.
4. Spelling mistakes were corrected.
5. No text copyright violations were detected.
6. The images were all legal for use, and some were clearly taken by the student!
Synopsis: The module gives the basics of the several ways to classify matter. It provides the distinction between heterogeneous, homogeneous, and colloidal mixtures. In relation to that, it explains ways to separate mixture, such as filtration and distillation. It also distinguishes between the solid, liquid, and gas states of matter while also discussing the rudiments of matter i.e. protons, electrons, and neutrons.
Detail Review: Flowcharts help in explaining the classification of matter visually. Picture examples of the different types of mixtures are appropriate and sufficient. Where it says “The image on the right is water being poured out of a glass. This shows that water has no shape,” the font is arbitrarily different, and should be changed to agree with the rest of the module. The overall length of the module is appropriate and the grammar and spelling are accurate.
Fix mistakes in the module:
From: “A homogeneous mixture is one in which the compositions is uniformly mixed throughout.”
To: A homogeneous mixture is one in which the compositions of its constituents are uniformly mixed throughout.
From: “Everything that is familiar to us in our daily lives from the land we walk on, the water we drink, and the air we breathe are states of matter called gases, liquids, and solids.”
To: Everything that is familiar to us in our daily lives - from the land we walk on, to the water we drink and the air we breathe - is based upon the states of matter called gases, liquids, and solids.
