Hello my wonderful students!!! Listen closely...are you listening??? This is your science teacher Ms. Yates. I know, I know. I just saw you a few hours ago. Remember the awesome reminders, updates, and fantasticness that I promised you?? It is here. Yep!! Right here. Remember to check it out daily. The rewards will be worth your time. Assignments that you forgot about or were absent for? Here!! Notes you may have missed?? Here too!!! Announcements?? Yep!! And, fantastic reminders of all the cool stuff we did today...All here and more!! See you tomorrow. Or Monday, if you are so awesome that you are reading this over the weekend.

Chromatography, Distillation and Filtration: Methods of Separating Mixtures
After watching the video...how would you separate a mixture of sand, salt, and iron filings??
jacob, to seperate the iron you use a magnet, to dissolve the salt you puthe sand and salt in water, and to seperate water from the sand use filter paper.
In this video it explained different techniques on how to separate mixtures, these included magnetism, distillation, crystallization, and evaporation. This sight gave very useful information, and helped me understand mixtures. I also learned about chromatography, more into detail, and I liked all of the examples, and "pictures/mini clips" that this sight gave. Over all it was very helpful!
First filter the salt water from the sand and iron. use a magnet to separate the iron from the sand. evaporate and condense the water into a separate container.
First you want to use a magnet to get the iron fillings out. then you put the sand and salt in water(in a container) and then use filter paper for the sand
In order to fully separate the mixture, use a magnet to take out the iron. Next, you should put the remaining mixture in water. Sand dissolves in water, so take out the sand with a porous drainer, but make sure the pores are not too big nor small. When the sand is removed, distill the salty water to remove the salt. Andrew
This video was very helpful because i actually had no idea what they were going to do to separate the things in the sand. It first caught my attention when they showed jelly bean.:)
Today we watched this video on getting metal out of sand and lots of other ways to separate materials. We also learned filtration, distillation, and evaporation. I can't wait to look at the lab. :)
To sperate the the iron filings from the mixture of salt and sand you would use a magnet

Use a magnet to get the iron out then put water in the sand + salt and pore it through a filter paper then evaporate water
