Separating Mixtures LAB

9/23/2011

A mixture is any situation when two or more substances are mixed together. In a mixture, the different particles are close to each other but they are not joined. This means it should be possible to separate most mixtures out into their component parts. To do this, you need to look at the physical properties of the different parts of the mixture to work out a method for separating them.

In the comments section, describe your experience and summarize the key learning you gained by doing this lab. Be specific, tell exactly what you learned.

You get to see what it all looks like. You also get to see what they look like when you mix them all together. When you boil it all the ater dissolved.

You can try and find out things when someone else goes and mixes them.

I learned that you can't be exact all the time, because material may be lost or a different material may be gained. I also learned that you can seperate a mixture.

You learn to sepertare materials. when you mix then you observe and see if you can tell the substances apart. You have to be careful so you are accurate in your measurements.

You learned well doing the experiment no matter if you were experimenting or just waching.

I liked the lab, too. we should do more labs like it, only much more comlicated with more elements and compunds.

the lab was ok and you separte different matrerials in differnt ways

It was hard, because i didnt listen but wheni finally understood it, it was easy.It was cool and I learned what a mixture is...I feel SMART!!

You learn how to seperate different substances in different ways so you can understand things alot better and how they work.

The lab was alright, we learned how to seperate materials and compounds in different ways and that you can evaporate water to see what get lefts behind.

The lab was ok, I guess, it's better than doing normal stuff.I guess I learned how to seperate mixtures.

i learned how to seperate mixtures. you observe them and see if you can tell the substances apart from other. during the experiment you have to be careful with the substances so you dont lose them. if you lose your substances your result wont be as accurate.you also learn how to seperate the mixtures.I thought this experiment was fun we should definately do more experiments like this ! :)

When you did this lab you found out what is magnetic like the iron. We learned how to seperate and mixture the substances together. You also learn which mixtures stay together when you pull them apart.

You learn how to seperate meterials. After you mix them you can observe and see if you can tell the two or more substances apart. You are supose to make your measurment as close as you can to be accurate.

The lab was easy at first, but then it got harder as you needed to separate the mixtures because I didn't understna dthe tricks you can use to separate them.

Mason Redwing (Chives)

I learned how to take apart a mixture by performing four steps, magnetic attraction, filtration, distillation, and evaporation. We also learned what the differences between compounds and elements. CHIves

I learned that the materials that you are experimenting with can be lossed so you have to be careful. I learned how to seperate materials carefully by magnetic attraction, filtration, distillation, and evaporation.

Tatiana

I learned that you can seperate different materials by doing something simple. And what pure substances, compounds, and elements are.

Sierra Tarabetz

I learned how to seperate all the materical back to how it was before. We use magnetic attracion, filtration, distillation, and evaporation.

Lucy

9/26/2011 05:51:25 am

I learned about magnetic attraction, fillration, distillation, and evaporation. We learned how to tell the difference between a compound and an element. I also learned about homogeneous and heterogeneous mixtures.

I learned that it is not the easiest task to remove one substance from a mixture. Also about how accurate you can get if you are careful enough.

Allison

During the seperating mixtures lab, I learned some new things. The first being that once you contaminate a substance it is very hard to get it pure again. The second thing I learned was how to seperate mixtures in a concise manner.

you learn how to seperate different materials, we learned the difference between compounds and elements

In this lab, I learned about the different methods you can use to separate the materials in a mixture. With materials that are magnetic, like iron, you can use a magnet to separate if from the mixture. For materials that are grainy, chunky or course you can filter out of the mixture. Finally, with materials that dissolve, you can boil the mixture so that the water evaporates and leaves the final material.

I learned in this lab that it is extremely important to follow instructions and to be careful with the expirements.

I learned how to seperat minerlas even if they are small. After you experiment them, and then figure what they make

I liked the lab, I learned how the pure substances can be separated from a mixture. I also learned about how each element reacts, whether you combine or subtract it from the other mixes.

I learned that You should not spill and if you do tell a teacher. Also you should read all the directions.

Raelynn

I learned that you should follow direction and what happens when you mix different matierals

morgan valandra

I learned that you should always follow the directions that your teacher gives you and listen to them to. Also how to mix different substances together. And also how to get them seperated from each other.

it was a very different experience when we had to mix and then seperated them. it was a very hard endaver working on this assignment with my partner Mason "the scared llama" Hoffer. It was also interesting to see masons method of doing this assignment. We also recieved help from Rachel" Big Money" Reuer and Haley "Big Mo" Stewart. Anyways, it was a very fun experiment.

Rachel :)

I learned how to seperate different types of things that took four different steps. i thought it was run becuase we got to use a filter and i thought that it was neat to be able to screen the sand away from the water and then the salt would go with the water and then when we boiled the water we got the salt back out of it ;). Also when we used the magnet on the iron it was really cool to see what the iron would do when you moved it,m it just looked really cool:)

Haley :)

9/27/2011 12:02:35 am

I learned how to separate different substance. It was fun but also kind of long becasue you had to wait forever for the filtering part. I also learned that when you combine some substances you can't get all of it back.

I learned that when you mix mixture some materials can be left behind and by doing that changes the mass. I learned that when you mix materials it changes the way it all looks and when you mix like sand and salt together you can see the diffrent layers. When you boil the salt water when all the water evaporates the salt comes back but not all of it comes back so the mass changes.

i learned what homogeneous mixtures are and also what a which elements are compounds and which ones are mixtures.

Candace patricia

9/27/2011 12:04:14 am

In this lab, i've learned that you need to follow the directions the teacher gives you,the difference between compounds and element also how to seperate mixtures.

Kyran

9/27/2011 12:04:55 am

I learned that u shud read all the directions first and to get all your work done while you do your lab.

Leahanna

9/27/2011 12:05:11 am

i learned that mixing different substances together you can separate them back to their original materials by using their propertis.

Lena :)

9/27/2011 12:06:33 am

i learned that when you seprate the sand the salt does just dissovoses and look like water that was cool.

JaTonne

9/27/2011 12:07:12 am

the lab was kewl i gess, it was klinda fun that i learned how to mix and measure stuff

Kohner

9/27/2011 12:10:47 am

I learned that you always have to follow directions or else you won't do the lab correctly. If you do the lab incorrectly, you possibly won't get a good grade. And I'm pretty sure we all know how to seperate mixtures now...(:
I also learned the difference between homogeneous mixtures and heterogeneous (Spelling? Haha) mixtures.(:
