The purpose of the lab blog is to do the thought processesing that goes along with the experiences that you had in the experiment.
Your blog post should be outlined as follows:
- A quick summary of the experiment, tell me what you did (a procedure) and what happened (your results). I am usually looking for roughly a paragraph here, you need to provide enough so that I can tell that you understood what you were doing.
- Answers to the lab questions, in this case they are:
- Explain how you can determine if a property of green stuff is a physical property, or a chemical property.
- Describe the different phases of matter of the chemicals (water is a chemical too) used in this experiment. Make sure to tell how solids, liquids and gases are different.
- Describe how the material relates to what we have been completing in class. Also this is where you can pose questions that the lab made you think about, I like to see this stuff and respond to it.
- Enrichment Questions: I will at times pose enrichment questions, if you want to get 5/5 on all categories all the time, you will need to answer these. For this experiment, come up with an experiment that you would like to try with green stuff. Its name is copper (II) chloride if you want to do a search.
In the lab Properties of Green Stuff we 1. observed the green stuff, 2. Put the green stuff into about 23ml of water, 3. Put a few drops of the solution we made while adding and mixing the green stuff together onto aluminum foil. 4. we tore but pieces of our aluminum foil and stuck it into the beaker of the solution we made. Some of my observations I made during this lab were, that the green stuff looked like little pieces of grains, various sizes of the particles, and it was greenish tanish color. While in the water the water turned blue and became one liquid together. Green stuff on the foil: the solution fizzes on the aluminum foil, the solution dissolves through the foil, black, and eats the paper and leaks through the foil.
ReplyDeleteThe green stuff is a physical property because it changed color in front of my eyes. Also, because it didn't have in changes that would make it chemical along with a PH level change etc. And if you were wanting to test this, you could separate each compound and nothing would change the chemical matter. The green stuff was the solid in our experiment because each little grain of chemical was compacted together and the form of it doesn't change. The water was our liquid in the experiment because the water doesn't have a specific shape, the shape change change depending on the container it is in. The gas of the solution burning through the aluminum foil was the gas in the experiment because the molecules in the gas can move in a random state of motion.
How can one chemical form all the 3 stages of matter in the matter of minutes? The material relates to what we have been completing in class by our unit that we are working on. We are working on the properties,types, and changes of matter and this is the perfect lab for that.
One experiment i would like to try is using a couple liquids to see if they copper (II) chloride would react differently. Maybe try using vinegar, water, and Salt water.
The procedure for our first lab Properties of Green Stuff wwent like this:1. Observe green stuff(My observations: it was flakey, greenish brown, organic looking, fine grained, no smell) 2. Put green stuff in no more than 25mL of H2O(My observations: water turned green, water is cloudy, flakes that didn't dissolve fell to the bottom) 3. Use dropper to put solution onto aluminum foil(My observations: the solution dissolves the aluminum) 4. Put the aluminum foil in the solution.(My observation: the aluminum fumed and dissolved, it also turned red)
ReplyDeleteThe property of Green Stuff is physical because when it hit the water it dissolved right away with no physical change in matter. Liquid: water, Solids: aluminum, and green stuff, Gases: when the solution had the aluminum placed in it the foil turned into a gas.
How are certain mixtures of chemicals able to change matter and others do nothing? This lab relates to what we are learning in class because we are on Unit 1: matter- it's properties, types, and changes.
I would like to experiment with different amounts of H2O and see how it effects the chemical reaction among the aluminum foil and solution.
In the lab, "the properties of Green Stuff", we had to follow a set of procedures like 1. observe the properties of the green stuff, 2. place the green stuff in about 25 ml. of water and make observations on what happened, 3. place a few drops of the green stuff and water solution on aluminum foil and make observations on what happened there and 4. place bits of aluminum foil into the actual water and green stuff solution a and make observations on what happened there. The original green stuff was very small grained, had no smell and was a greenish brown color. When i put the green stuff into water, the water changed colors from colorless to blue, most of the green stuff dissolved but the particles that didn't dissolve fell to the bottom. When placed on aluminum foil, the foil began to fizzle and it eventually dissolved where the green stuff hit and left behind brownish powder. When pieces of foil were dropped into the solution, they also fizzled and it dissolved down to a softer, brownish red ball.
ReplyDeleteThe green stuff itself was a physical property because it alone didn't change anything chemically. It alone was small grains of physical matter and when placed in water, it only dissolved which is a physical change. The solids in the experiment were the original, undissolved green stuff and aluminum foil. The liquid was the water and the gas the fumes that were produced when the green stuff was placed on the aluminum foil.
This has to do with what were doing in class because in the lab, we witness all three stages at some point, ( a solid which is a solid object that's not flow-able and has molecules tightly packed together), a liquid (which can flow and its molecules can pass through each other), and a gas ( which whose molecules ore the furthest apart from each other and move the fastest constantly) and how you can change them physically and chemically.
I would like to experiment to see weather or not copper 2 chloride would affect any other metals like it affected aluminum foil.
In my first lab, Properties of Green Stuff, I experimented with a flakey green substance also known as copper chloride. The first step in the procedure was to obtain all items needed for the experiment including safety supplies such as goggles. The second step in the procedure was to observe your copper chloride throughout the whole testing process, beginning and end. Third, you had to put the green stuff in the H2o; approximately 25 ml, and then stir it until it turns a cloudy, light blue color. Next, you had to suck up some of the blue liquid using a dropper and put it on the aluminum foil. Once this happens, you begin to see the foil dissolve and turn a red/magenta color. The last step is to take the foil and put it in the blue water. Over time, the water begins to change to a light brown color and begins to fiz causing the foil to dissolve completely.
ReplyDeleteThroughout this lab I learned numerous things, the properties of Green Stuff to be more precise. I learned that just a small amount of the copper chloride added to a piece of aluminum foil can burn right through it, creating a hole. Also, although it's a greenish brownish color when you first get it, when added to the water it changes to a light colored blue instead of a green and or brown color.
Some questions I had during this experiment was why at the beginning, did the water not change to a green or brown color instead of a blue? and what specifically is the copper chloride used for in real life?
My first lab was called Properties of Green Stuff.Green Stuff is copper chloride which is a green flakey substance. To start the procedure we had to get all the needed supplies: beaker filled with 25mL of water and a beaker with a little bit of copper chloride. We also needed aluminum foil and we needed to wear some safety goggles. So next we put the copper chloride in the water and stir it. The water turned to a blue and cloudy mix. Next we took some of the mixed water and copper chloride and used a dropper and put some on the aluminum foil. As soon as that happened the aluminum foil started to dissolve, turn a redish color and make a fizzing noise. The last step was to put pieces of foil in the beaker of green stuff. When this happened the foil started to dissolve and the water turned a red cloudy color. The foil dissolved completely as well.
ReplyDeleteThe property of Green Stuff is a physical because when it hit the foil it burned right through it. The solids in the experiment was the green stuff and the foil. The liquid was the water. The gases were when the aluminum foil was placed in the solution and it turned into a gas.
The material in the experiment relates to the stuff we learned in class. Such as, taking observations and safety. Also seeing the three stages from liquid to solid to gas. Some of my questions during the experiment were what happens if you add to much water? or if you add to much copper chloride?
An experiment involving copper chloride could have something to do with the temperature of the water. Maybe the hotter the water the faster the foil dissolves or if its ice water it doesn't dissolve at all.
The first lab was called properties of green stuff. The green stuff is a substance called copper chloride whish is a light brown and green powdery substance. Next we used 25 ml's of water. we put the copper chloride in the water and stirred it and the water turned blue. Then we poured some of the liquid onto the aluminum foil. The water started to fiz and started turning redish color.
ReplyDeleteThe green stuff was a solid because each grain of the chemical was compacted together and its form doesnt change. The water was the liquid because it doesnt have a shape, the shape changed depending on the container.
The first lab We did was the properties of green stuff. The green stuff was brown and green flaky/powdery substance that reacted with water in a unique way.We mixed 25 ml's of water with the green stuff which then turned the water blue then we used liquid droppers to put a drop on a small sheet of aluminum foil.It began to fiz and smoke. We then put pieces of the foil into the cup of water that was mixed with the green stuff and the foil dissolved and the water became a brown color. This was a chemical change because the foil was broken down and can not be changed back.
