Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Should the state have the power on how much water we use and finalize it as a law? I strongly believe‚ we should have a law when it comes down to water.This drought that California is having is really effective. For example‚ Pete Rodriguez a retired dock worker says‚ “I don’t know how long we can stay here”(Source 2). Meaning because we are running out of water he has to take one and a half hours out of his day to haul water because the well behind his modest rented home went dry.

theories is the behaviorist theory‚ the cognitive theory‚ the critical period of hypothesis‚ and Natural order hypothesis. First of all is The Behaviorist Theory which the theory it is believed that the second language learning learner tries to imitate what he hears and practices the second language regularly to develop habits in the language. This theory also believes that learners try to relate their knowledge of the native language to the second language and this could lead to positive as well as negative

My Science Project Can water float on water? My Prediction I predict that water can’t float on top of water. Simply because it sounds impossible‚ but it will be interesting to find out if however it is possible. The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they
