Station 4 In station number 4, in that respect was a cast down bulb screwed into this contraption that had deuce black poles, called terminals, abeyance down from it. This contraption, called a conductivity meter, was plugged into an outlet in the wall. There was also three beakers of irrigate labeled A, B, and C. We had to trial run each beaker by determineting the terminals into the weewee and seeing if the wakeful bulb lights up. When we tested the beaker labeled A, zippo happened. So we act beaker B and the light lit up. It wasnt that bright, just it lit up. finally we tested C, and it was so much brighter than B. At first we werent positive(predicate) why the light lit up differently, only when consequently we thought that it had to do with what was in water supply. We remembered that brininess in water can affect the movement of electricity, which is currency. In beaker A, on that point was no salt, in beaker B there was little salt, and in C there was a chew of salt. You see, when you add salt into water, the salts molecules cleave and combine with the water molecules. This allows the electric current to eat from unitary terminal, through the water, and to the other terminal. Thus creating a duty tour to light the light bulb. This has to do with marine biology because the oceans ar make copious with salt. Scientists test the amount of salt (salinity) in the oceans using a salinity meter.

They are now attempt to find ways to produce energy using the oceans and indite the atmosphere. Station 5 At station 5, there was a beaker, a golf earth, a s poon, and salt. We had to fill the beaker wi! th water and get a line to get the golf en to stay in the kernel of the water. Now from past experiences, I know that golf dinner party dresss sink when dropped into water. So, we started to pour salt into the water, dropped the ball in and secret code happened. So I poured a lot more salt in, and dropped the ball in again and it floated, but it was at the acquit and not the bottom. So I put more water into the beaker to make it less concentrated and the ball stopped in the...If you want to get a full essay, order it on our website: BestEssayCheap.com
