The only difference is two photogates will be used to find the change in velocity.

After we were finished, we discarded the used glucose test strip. The pre-lab usually includes an objective, references, answers to pre-lab questions, table of reagents and an experimental plan. We could have gone over the time or behind. That one is not as puzzling as you might think.

Experimental Plan In order to help make your time in the lab more efficient, you are required to formulate a flow chart to summarize the key points of your experiment. The formula for water potential is: Were your errors random.

What should go into a lab report. Your goal for this part of the report is to allow anyone reading the report to duplicate your results. The conclusion section should be in paragraph format and discuss the success or failure of each airbag design. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence.

But you also must record here any changes you made, or variations in that procedure you chose to do, or had to do based on your equipment. The relationship of the curve down is not consistent. We then cut a hole into the bag large enough for a glucose test strip to enter.

Appendices — include your additional data tables and other related materials. Where n is the moles of CO2, what you are solving for, P is the pressure of the room be sure to convert it to atmV is the volume of your airbag in L, R is the gas constant 0.

Punch 15 holes by the hole puncher to make 15 equally sized paper disks catalase. In this labs case, a picket fence is placed on top of the cart and is positioned to pass through the photogate while the cart is in motion.

Place the paper disk using a pair of tweezers at the bottom of the beaker.

Plot ALL graphs manually. The conclusion should just be a few sentences that relate to whether or not you met your objective. Only report what you observe.

This can be done using the molarity equation below: If you need additional help with these calculations see the procedure.

If your lab handout includes questions to be answered, include those answers here. Each slat will block the photogate momentarily as the picket fence passes through. For the density of the metal cylinder section be sure to report the density and identity of the unknown metals.

I only want you to have more information about the different parts of a lab report so that you can better instruct your student about labs and possibly give them a lab critera sheet at the beginning of the school year. We were to indicate initial locations of molecules and predict in which direction they would move in diffusion into the bag, out of the bag, both into and out of the bag, or none.

If you just followed the procedure from a laboratory manual or experiment handout, you can say that the published procedure was followed. In the discussion, you are correlating all your results and showing how they relate to your objective. This was not that hard of an experiment, I did not find one part to be more difficult than the any of the other parts.

Hypothesis is rejected or accepted based on the data. Repeat steps with 2 other paper disks then calculate the results average the results. Glucose was initially in the dialysis bag and is predicted to flow in and out of the dialysis bag and exist in both the cup and dialysis bag.

The final volume of the submarine is determined using: Raw data will probably be most effective in table format, with the highlights summarized in graph form. theoretical percent recovery from the crystallization of g of acetanilide from ml water.

(assuming the solution is chilled at 0 oC). 3. If your experiment yield of acetanilide is greater than %, how could this occur? 4. Describe how would you separate a mixture of acetanilide and sand. 5. Experiment 3 Limiting Reactants Introduction: Most chemical reactions require two or more reactants.

Typically, one of the reactants is used up before the other, at which time the reaction stops. The chemical that is used up is called the limiting reactant while the other reactant is present in excess.

As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students%(6).
