Abstract The abstract is a one or two paragraph concise, yet detailed summary of the report. Tables and Figures - Should be used when they are a more efficient ways to convey information than verbal description. Accept or reject your hypothesis. In this experiment we will first calibrate our thermometers using ice and water, whose normal melting and boiling points are well characterized as 0. Figure out what you are attempting to solve or test. It should be sufficiently detailed for anyone to be able to repeat your experiment.

Just summarize the main points, calculate averages, or give a range of data to give an overall picture to the reader. There are rules in place to protect your health, the safety of others, and ensure the lab protocol has the best chance for success. The 25 mL graduated cylinder is where the water will be displaced into as the carbon dioxide gas enters the water chamber from the reaction chamber and displaced the water. It will also be conducted with everyone in the lab using safety goggles and everyone wearing closed toed shoes. Put the calcium carbonate aside until you are ready to react it with the 1.

First, place a piece of weighing paper on the balance and tare it. Second, lab reports are easily adapted to become papers for peer-reviewed publication. Another purpose is to understand how fireworks work. To displace the water and measure the amount of time it takes to displace it we will use a water displacement apparatus that will allow us to take the carbon dioxide gas produced to enter a water chamber and displace the water from that chamber into a 25 mL graduated cylinder, and we will use a stopwatch to time how long it takes for 15 mL of water to be displaced. Your abstract needs to be able to stand independent of your lab report.

To demonstrate how changing the temperature at which a reaction takes place affects the rate of the reaction, the reaction between calcium carbonate and 1. Of course, you can use the structure we have provided above and write a lab report yourself. Why is the amount of water that is added to the flask during the titration not measured accurately? Composing lab reports is not only a difficult thing to do but also time-consuming activity. Notes: For references we used our textbook, lab manual, and the Chemical Handbook found on shelf 2 of the library behind the reference desk. One of the most common activities in chemistry is doing experiments in the laboratory. For students serious about pursuing a career in science, a lab report is a stepping-stone for submitting work for review.

Titration, an analytical technique, allows the quantitative determination of a dissolved substance being titrated, known as an analyte. Check for grammar, punctuation and typing errors. Stick the thermometer into the hydrochloric acid and wait until the temperature of the hydrochloric acid drops to about 10? Changes include any change to the procedure written in the lab manual, this includes glassware and concentrations, as well as chemicals. While waiting for the temperature of the 1.

Another purpose was to understand how fireworks work. We understand this because we know it is not an easy thing to do. Decide on an appropriate style of abstract for your lab report. Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. You would highlight every tool that you used. The report is used to demonstrate what has been learned, and it will provide a way for other people to see your process for the experiment and understand how you arrived at your conclusions.
