WATER & ALCOHOL : # 1
the first thing we did in our water lab is to drop one small drop of water in one hand and in the other hand we drop alcohol and alcohol was cooler. alcohol is cooler than water because alcohol doesn't have the chemicals bonds like water, so water evaporates faster then alcohol so it cools your skin.
water tension/cohesion:# 2
for the second water lab we had to figure how many drops can it take on top of it before it overflows my friend predict six and i predicted nine and the material we were using was pipette and i was using the pipette and my friend was counting and we were going one by one it took so long and apparently it took sixteen drops to overflow. The reason it took so long was because the water molecules were sticking to the other molecules the molecules are called cohesion and if you look closely in the side of the penny you see semi-sphere and another name is dome and that process is called cohesion.
SURFACE TENSION/PAPER CLIPS ON THE SUFACE OF WATER (CUP): # 4
station number four was trying to get a paper clip on the surface with out it sinking and the material were beaker,paperclip the point of this is to figure out a strategy so we could make the paperclip we weren't successful at it but we manage to make one paperclip to float. The strategy was putting a paper on to the other paperclip and slowly putting it down you don't want to go to fast or it well sink and gently slide it to the side bring it up with out moving the beaker.
ADHESION STATION GRADUATED CYLINDER: # 5
If you are doing a water and you are using material called meniscus if you pour water in it you will see curved line instead of straight line and if you don't know what's happening its
because there's a property called adhesion and the reason it stick's to the meniscus is because it stick's to the molecules and try's to climb against gravity
CAPILLARY ACTION STATION ROLLED UP PAPER TOWEL: # 6
the final lab i did was me and my friend daniel we were told that we were suppose to use two beakers and fill it up of with water and put a blue stain so the water was blue so we were also told to put a rolled up paper and to put one side of the paper on one side were the beaker is empty and the other with blue water and wait tomorrow and we could see the water climbing up that shows us how the water gets up on the tree and thats how it grows.
