polluted water so the water will have a clarity of 0%. If a filter is built for the polluted water‚ then the waters clarity will be 0% and the pH value will be 7. The purpose for this lab is to get the polluted water to a clarity of 0%. Water pollution is playing a major role in today’s ecosystems because the water is becoming unsafe to live in and unsafe to consume. “Water pollution is any physical or chemical change in water that adversely affects organisms” (Chiras‚ 2015).

project is to determine whether river water or lake water is cleanest as it relates to tap water. The independent variables being tested in this experiment are the different waters being tested which are river water‚ lake water‚ and tap water‚ which is the control. The dependant variable is which of the three waters are the cleanest as it relates to unfiltered tap water. The purpose of this experiment is to determine what the different aspects of the three types of waters are and how that relates to cleanliness

Water quality is determined by three major classes that are biological‚ chemical‚ and physical. The biological class has to do with the organisms that are living in the water and how many organisms that there are. Some of the organisms that live in the water have certain physical and chemical

First‚ the matting was placed on the four slides‚ cover-slips as well as the container of blood on top. Blood containers are in dropper bottles. Number each slide with a wax pencil. A drop of blood was placed on a slide and numbered it slide #1. Slide #1: 1. With the wooden applicator stick‚ dip the end into the blood and place a tiny drop onto slide #1 and put cover slip over it. Slide#2 1. Place 1 drop of 0.9% NaCl with the drop of blood (use the filter paper to absorb excess liquid). 2.

Take the 100ml glass beaker and place it under the water tap’s opening‚ the place where the water comes out from‚ then turn the tap on. Do not turn the tap off until the water inside the beaker reaches the 50ml mark‚ to ensure that there is only 50ml of water in the 100ml beaker. Then take the beaker and place it somewhere safe on the table. After that take the scale and plug it’s wire in the socket‚ then

The formula for‚ s(t)‚ for the function that models the height of the water balloon at time t‚ in seconds‚ is s(t)= -16t2 + 350t + 4. We can determine how long it takes for the rocket to land from the graph where the function intercepts the x-axis because this is the value where the height of the rocket is 0 feet. From the
