Now we are back on track at school and i hope everyone had a great vacation! When we came in today Mr.Finley told us about the new website updates! If you look over at the school website somethings have changed. Its not a big deal but the URLs have changed. So if you put Mr.Finley's(or any other teacher's) web page as a favorite/bookmark, you are going to need to change them. Sorry for the inconvenience. Now lets start the science!
Yesterday we talked about ACTIVE TRANSPORT and some of us were lost because we don't recall learning about ACTIVE TRANSPORT. So today in class we read page 60 in the Science Text books. We read a little bit about ACTIVE TRANSPORT. What is ACTIVE TRANSPORT you ask? Well ACTIVE TRANSPORT is the process of using energy to move materials through a membrane. After we read one page and took notes we put the books away. Afterward, Mr.Finley told us to take out our homework. Last nights homework was to explain/draw examples of ISOTONIC, HYPERTONIC, and HYPOTONIC.
What do those words mean highlighted in blue??!!?Well here are the definitions of ISOTONIC HYPERTONIC and HYPOTONIC.
Isotonic-a liquid solution that has an equal concentration compared to something.
Hypertonic-more concentration; higher concentration than something else
Hypotonic-low concentration compared to something else.
Remember when you are talking about the 3 new words above they are ALL LIQUIDS!!!!!!!!!
Now, an example of hypertonic and hyptonic is when you don't mix ice tea correctly. When you don't put enough ice tea mix/powder then it is hypotonic because it has less concentration and it just tastes like water. But then, if you put too much powder/mix then its hypertonic because it has more and tastes super sweet! An example of isotonic would be the perfect ice tea that isn't too sweet and isn't too bland. Its equal!!
Here is an example of ISOTONIC. Lets say you have two cups of tap water and one was in a big cup and another was in a small cup. The big cup of water had 0.2 grams of salt per 1 ounce. Then if you pour the same water into a smaller cup its isotonic because it has the same concentration, nothing has changed about the ratio of 0.2 grams of salt per 1 ounce.
After explaining isotonic, hypertonic, and hypotonic and hopefully almost everyone got it, we were dismissed.

Hey! thanks for the help for letting me understand what actice tranport is- it was oober confusing! But now i understand it well. But a question i had was what exactly is passisve transport?? it seems a little weird to me because if active transport is the process of using energy to move materials through a membrane, then is passive transport like the oppisite? i have no idea! but thanks anyway claudia for the help!

Passive transport: transport of a substance across a cell membrane by diffusion(Diffusion: the process in which there is movement of a substance from an area of high concentration to a lower concentration); energy is not required
