Teach Basic Lab Techniques

As both student and Art Educator, I support the idea that we all should be free to practice laboratory pedagogy. Just like how Leistyna and Woodrum mentioned that learners from the younger generation are more eager and demanding than the previous generation, they don’t want uniform healing/teaching or unknown spirit and want meaningful knowledge. If I were in my student’s shoes as a learner, I would demand the same thing and with my needs and opinions are valued and acknowledged by my teachers, I would be more engaging in learning and encourage to make the best out my education.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

I took the graduated cylinder and started filling it up with water until the bottom of the meniscus was to the the 100.0 mL mark with the assistance of a dropper pipet. I then took the 13 x 100 mm test tube and slowly poured the water from the graduated cylinder into the test tube until it was full to the top. I then poured the water in the test tube out into the sink and put the graduated cylinder on the counter so I can get an accurate measurement of the lower meniscus to record on my data table. I once again followed the same procedure again filling a second test tube with water from the graduated cylinder then setting it on a straight surface to get an accurate measure of the volume to

5. Calculate the mass of the water by subtracting “Mass A” from “Mass B.” Record the mass of the water in Data Table 4.

2. Read and record the temperature of the gas using the thermometer attached to the container.

Place the beaker on the hot plate, place the thermometer in the beaker and set the hot plate to 5oC.

Since a graduated cylinder is usually used for liquid measurement, students think they need to put water in the cylinder. This is not

-The more dissolved oxygen in the water, the more fish is observed in that area of water.

Volume of water This was kept constant by using a 200 ml beaker to fill up the jars used in the experiment. The uncertainty of the volume of the water was: +/- 10 ml

Then obtain the mass of the two flasks with the deionized water in them. If the mass of the water is between 9.9 g and 10.1 g then you can continue. If the weight of the water does not go between that range then get two flasks with water that reach that range. Record all trials in data table.

Rinse the beakers and fill both with 125 ml of water each. Place one egg in a beaker and place the other egg in the other beaker. Record the density by subtracting the current reading of water in the cup by the original amount of water in the beaker.Leave both eggs in their beakers alone for 48 hours. After the 48 hours, take both eggs out of their beakers. Clean both beakers for reuse. Fill one beaker with 125 ml of corn syrup. Fill the other beaker with 125 ml of water. Lave bother eggs in their beakers alone for another 48 hours. After the 48 hours, take both eggs out of their beakers. It is time to take measurements and collect data. Take a ruler and measure the height of both eggs. The take a bit of yarn (enough to wrap around the eggs) and wrap the yarn around both eggs separately to get their individual circumferences. Then place both eggs on the grams scale individually to get their weights. Observe their color and shape to get some qualitative data. Rinse the beakers and fill both with 125 ml of water each. Place one egg in a beaker and place the other egg in the other beaker. Record the density by subtracting the current reading of water in the cup by the original amount of water in the beaker. Clean up and the experiment is

This lab is all about measurements and recording them properly. The lab first introduces to use the measurement of centimeters, millimeters, and meters to measure different household objects in our everyday life. We were given the task to use the provided ruler and measure a CD, key, spoon, and a fork in centimeters and then convert our findings to give us the appropriate units of millimeters and meters for each object required in the exercise.

Procedure: This lab starts off by making sure the logger pro and temperature probe are in proper condition. Then, the data collection must be adjusted to 15 minutes and 12 samples/ min. After that a Bunsen burner must be set up by assembling a ring-stand, ring, and wire gauze, and a crack-less beaker is used to boil some water. First the beaker and the large watch glass need to be weighed and the mass has to be recorded using a triple beam balance. Next, the beaker with 200g of ice is placed on the ring stand, and immediately heated over medium flame. An important note is to make sure the flame is perfectly adjusted so the ice does not melt on the counter while trying to adjust the flame. Furthermore, place the temperature probe in the ice so it is not resting at the bottom of the beaker, it is best to secure it with a small clamp. Additionally, click the green start button on the computer and stir continuously with a glass rod until the ice is completely melted. Once the ice has melted which is somewhere between 3-5 minutes, the stirring rate will slow

A 100 mL graduated cylinder should be used to measure out ~40 mL of water.

In this experiment, The purpose of this experiment is to investigate the measurement of the actual volume contents of volumetric glassware. In the beginning of the experiment, the volumetric glassware should be clean and dry before used. The volumetric glassware, measuring cylinder and pipette should be handled with care and all the precautions were be taken during the experiment was held. This was to ensure to avoid any errors such as parallax error especially while reading water meniscus. This experiment must be repeated three times or more and take the average reading to get more
