Water

Water is more than just what we drink or what we wash our cars with, it is a pretty complicated part of science. It is pretty well known that water covers 70 percent of the earth. What you may not know is that there is a little bit of water on any surface. Also, water is made up of two hydrogen atoms and one oxygen atom. Water has a high heat capacity and that’s why its valuable in a cars radiator. Water molecules are not linear but bent in a special way and that’s why the molecule is partly negatively and positively charged. Water can be found in three states. One being a solid, for example, frozen water(freezes at 32 degrees). Water can also be found in a liquid state which is pretty much common sense. Water can also form into gas like vaporization. Water is constantly changing, interacting and in movement. Also water molecules are cohesive and adhesive and that’s why its allowed to fill a tubular vessel. Cohesion allows water to run up veins in a tree. When doing the lab I learned water has a high surface tension and that’s why the water didn’t fall off the edges when we put drops of water on it. One thing I didn’t know is that water is a big factor in the warming and cooling of the earth, but it makes total sense when I think about it. Yes this is a lot of information but it is very good to know.

Double Blind Placebo-What I Learned

For the past few days we've been working on clinical trials. This is somethig i really had no idea of. This involved using the double blind placebo effect.  Therefore this meant that;

1-double blind meant the doctor nor the patient knew what medicine was being handed out, all they knew was that they either got a sugar pill or the actual pill that is being tested.

2-Placebo stands for the sugar pill that is recieved.

This type of experiment is done to help protect the results.  I say this because if someone is told they have the pill that will "cure" then they will do things in different ways and most likely have positive thoughts.  All this put together will affect the results because positive thoughts or acting in a happier way can literally get rid or help some problems that the pills are trying to cure.  An example of this is like when you hear of people recieving choclate pills for a diet and then when they come back, they"ve lost weight.  Its sometimes all in your head. 

I learned there are tons of new drugs being tested every day. I had no idea! There are seriously drugs being tested for anything i could think of.  It was prety crazy and cool.   In addition these tests affectly me greatly.  The drugs tested now are cures for tomorrows defects or diseases.  They may one day help me, a friend of mine, or a family member and this is very beneficial to me.
