Finding the amount of oxygen in room temperature water
Your teacher will have a bucket of aerated water at room temperature that you will use for your investigations. Your teacher aerated the water by bubbling (forcing) air into the water overnight with an aquarium air pump.
Create a spreadsheet for recording dissolved oxygen and varying temperatures including the room temp (water), warm temp (water), and hotter temp (water) . Refer to Technical Hints to see how to create a spreadsheet.
Obtain a Styrofoam cup of heated water from your teacher. Be careful to hold the cup so that it doesn't tip. The thermometer will make the Styrofoam cup top-heavy. Take the temperature of the water.
After connecting the dissolved oxygen probe to the computer, measure for thirty seconds the amount of dissolved oxygen found in the room temperature water with the DataLogger software. Refer to Technical Hints to see how to use the DataLogger software to measure dissolved oxygen.
Transfer the final dissolved oxygen measurement for room temperature water to your spreadsheet. Refer to Technical Hints to see how to transfer data to a spreadsheet.
