Pure Substances and Mixtures Chapter Vocab

Atom – Are the smallest unit of an element that maintains the properties of that element. – (“A A” like universe)

Element – is make up of one or more of the same kind of atom chemically combined – http://www.youtube.com/watch?feature=player_detailpage&v=X5pSnBLfGnI

Compound – is made up of different kind of atoms chemically combined. Compounds have different properties from the elements that make them up. – http://www.youtube.com/watch?feature=player_detailpage&v=8vLnn274r3c

Mixture – contains a variety of elements and compounds that are not chemically combined with each other. Mixtures can be separated by Physical changes. – http://www.youtube.com/watch?feature=player_detailpage&v=cq9gLT9H-vY

Pure Substances – is a substance that has definite physical and chemical properties such as appearance, melting point, and reactivity  (elements and compounds are pure substances)

Homogenous  – Substances are evenly spread throughout – (SAME SAME SAME)  http://www.youtube.com/watch?feature=player_embedded&v=-PnPrlF7zgs

Heterogeneous – mixture is one that does not have a uniform composition (DIFFERENT DIFFERENT DIFFERENT)   – http://www.youtube.com/watch?feature=player_embedded&v=mvx5Vb7wg3k

Suspension – are mixtures in which the particles of a material are spread throughout a liquid or gas but are too large to stay mixed without being stirred or shaken.  If a suspension is allowed to sit, the particles will settle out. – http://www.rit.edu/ntid/sciencesigns/ (Wiggly fingers mixture)

Solutions – one substance is dissolved into another substance. – http://www.rit.edu/ntid/sciencesigns/ (like Tea)

Colloids – falls between suspensions and solutions – the particles in a colloid are spread throughout a liquid or gas. (They are heterogeneous) – http://www.rit.edu/ntid/sciencesigns/ (MIXTURE + DIFFERENT many times)

Self Check…

Every once in a while I forget what my job is… I get way more involved in what’s going on in the classroom than I should. I’m human, it’s allowed.  Anyway, after those days I end up feeling lousy and have to take a day or two to get myself in check.

Thankfully, Classroom Interpreting has many reminders for me to review.  I believe I have a good self-realization thing going on so that I know when I tend to cross the lines and can reign in my actions quickly.

Professionalism is important.  Not only towards the teachers in the classroom but for all students as well.  Without that we can be labelled a troublemaker and find ourselves without a job.

When I feel those breaking points about to boil up and out, I’m going to count quietly to myself to calm down before I let any unprofessional-ism leak out.

If you have any suggestions or comments please feel free to leave them.

Super Bowl “Deaf” Facts

Two former Super Bowl players had hearing loss??

• ·         Reggie Williams, Cincinnati Bengals, played in two Super Bowls, 1982 and 1989!  His hearing loss was identified when he was in the third grade.
• ·         Mike Singletary, played in the 1986 Super Bowl (XX) with the Chicago Bears defeating the New England Patriots.  He wore a hearing aid all his life.
• ·         Kenny Walker and Bonnie Sloan were both NFL football players who were profoundly Deaf.  Although played in the NFL, they both never had the opportunity to play in the Super Bowl.
• ·         Art Modell, the late owner of the Baltimore Ravens had a huge scoreboard built in their new stadium.  He had the scoreboard made with closed-captioning!  His son, John Modell was honored by the Maryland Association of the Deaf for his work in setting up the scoreboard with captions.  Currently, several stadiums provide captioning for football (and baseball) fans who are Deaf/HH.

 

Be safe and enjoy you Super Bowl Weekend!
