The intention of the “Foul Water” lab was to purify a sample of sewage water and conserve as much as possible. The water should be clean enough to wash your hands with. My hypothesis is that the water will be cleaner than the initial water sample‚ but not to the standard that I would wash my hands with. Significant terms to know include purification‚ filtration‚ adsorption‚ volume‚ clarity‚ dissolved‚ filtrate‚ impurities‚ pipette‚ clay triangle‚ funnel cone‚ iron ring‚ beaker‚ and Erlenmeyer flask

Steel Wool Scissors Ruler Lemon Juice Orange Juice Vinegar Distilled Water Four Small Bowls Thin Towel Tall plastic cup Graph Paper Procedure: Before beginning your experiment‚ make sure that the distilled water has been opened and exposed to the air for at least a few hours. This will allow it to absorb some carbon dioxide from the atmosphere and lower its pH from a level of about 7 to about 5.8. The distilled water will act as a model for "normal" rainwater‚ which has a pH of about

Introduction: This lab investigates the question‚ what is the water quality of the U-High creek based on micro invertebrates found in the creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater

1. Put your safety goggles and lab coat on. 2. Gather all the necessary materials in order to conduct this experiment such as boiled water‚ distilled water‚ calcium chloride‚ distilled water‚ glycerin‚ test tubes‚ nails‚ test tube rack‚ graduated cylinders‚ tongs‚ scoopula‚ erasable marker and parafilm. 3. With the erasable marker‚ label the ten test tubes from 1 to 10. 4. For Test Tube 1‚ drop an iron nail in it without adding anything else. Place the test tube into the to-be-heated rack (50⁰F)

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).

temperature affect radish germination. The original hypothesis was if temperature affects the tail length of the germinated seed‚ then a higher temperature will lead to a significant decrease in the tail length of the germinated seed. This hypothesis is true‚ according to the collected data. After 6 days of letting the seeds germinate‚ the ones that germinated in room temperature were quicker to germinate and with a lot more tail length compared to the ones in the incubator. In fact‚ the seeds from the incubator
