Separating Mixtures

1. 
   
   1. 1. First, drain water from plastic cup into flask using the spoon and the funnel.

2. Remove the toothpicks from the plastic cup (with fingers) and place them on the tray.

3. Remove beans from cup with the scooper and place on filter paper.

4. Pour water from flask into graduated beaker and place on the hot plate after plugging it in.

5. Remove excess water from the plastic cup with pipette and drop into graduated beaker while it is on the hot plate.

6. Remove marble from plastic cup, with fingers, and place on filter paper.

7. Remove black grain-looking substance from the plastic cup and put on filter paper.

8. Use magnet to see if the substance is metal. It is attracted to the magnet, which means the items iare metal filings.

9. Try to remove all iron from the magnet. (Using your fingers works the best)

10. Identify the substance that is left in the cup: sand.

11. Remove the graduated beaker from the hot plate. Unplug hot plate.

12. Wash the scooper with water.

13. Remove the result of the heated water from the beaker using a scooper and identify. (We identified the substance as being slat that was dissolved into water.)

14. 
    14. Clean and wash all your materials.

                                                                               golden door of freedom."

                                                                                             - George Washington Carver 

                      This quote has many meanings to consider when you think about it, but there a few that stick out above the others. First of all, I completely and utterly agree with this quote. The first meaning that came to my head when I saw this quote was probably the most common one. Freedom is a luxury that not many people have, and it s very much golden. Education is one of the most important necessities in life. Without it, life won t be easy. If you lack an education, you are pretty much trapped in a range of jobs that probably don t place very high in society or ones that have a big salary. Since this is what I would consider as being trapped, being educated is definitely the key to having freedom in your selection of jobs and many other things. Another meaning to this quote could be that having knowledge gives you the freedom to compete in different types of competitions or get into advanced careers. It could even help find new friends and meet new people depending on what you know and your interests. If you took it to another level, this could also apply to law. If you were accused of committing a crime of something of the sort, your knowledge in law (if you studied it) could help you be cleared and found innocent. Education not only opens a door of freedom but it opens many other doors: great careers, amazing people, and being able to support a family. All in all, freedom and education go hand in hand.
