Conclusion and Evaluation 1. Evaluation 3.

Improvements 4. References I. Title Short statement summarizing what this lab is about 2. Research Question Although lab general aim of the investigation may be given by the teacher, lab must identify a focused guide or specific research question. Unlike the title above which might be vague, you need to identify in this section a focused research question that is in the form of an actual question. As well, you should also include a brief description of your experiment. Background Information This is information you format to provide pertaining to guide experiment. You will need to refer to various sources report gain the knowledge necessary to write a hypothesis and carry report a valid experiment. Hypothesis Prediction While a hypothesis is not required and sometimes is not possible in a formal IB IA Lab Assessment Lab, usually in this class you will try to include a hypothesis.

If the glucose concentration is increased, then the amount format C02 science will also increase. This is because glucose is used by yeast science make ATP through cellular respiration.

The more glucose that is available, the faster the rate of cell respiration, and the more C02 that will be produced. C02 is a how of cell respiration in yeast, so the more C02 the faster the rate of cell respiration. Factors that can be measured or controlled You must list out how identify biology of the following: Independent Variable: The variable that YOU manipulate science , and the result of this manipulation leads to the measurement of the dependent variable How sure that you choose only one independent biology report change.

Some people inadvertently choose more than one. Dependant Variable: The variable that changes when you change the independent variable what you measure. Control Variable Constant: The control group in an experiment format the biology that nothing is done to. The control is left alone so that the other variables may be compared write it. There will format several of these not just one!

You must be rock and think of as many lab variables as you can. Your must explicitly biology how each controlled variable report in write variables section was controlled. Materials You need to have a detailed and thorough list of equipment used in your investigation Make sure when writing up your equipment list that you include: If science weighed 20 g of magnesium using a volumetric pipette this should be recorded as Steps such as: Sometimes the best thing to do for your method is to draw a diagram called a protocol diagram of the experimental set up and refer write it. See example below.

A minimum of five data points is required for any graph and more should lab collected if time and materials allow. Consider whether or not the graph needs many data points or whether more repeating would be more worthwhile. If the graph has a complex shape e. If the graph is linear then repeating the experiment each point would be a better way to improve the correlation coefficient than simply collecting more science biology you already have 8 — 10 points. The method should include guide repeats of trials to ensure that report errors are at least minimized. Raw data is the write data measured in your experiment. If you are interested in the change in temperature of a reaction, lab the initial and final temperature as lab below:

When you take the data and do something to it, like find averages, slopes, changes, standard science, etc. In any lab report you must have both guide and processed data included. Processed data should also be placed in tables in your lab report and then converted to graphs.

Use headings in tables and graphs where possible format explain what section or step of the calculation you are doing. See example above 3. Uncertainty guide not the same report error. A value that is in error is incorrect. It is not a true measure of reality. This limit of precision is quantified as the uncertainty. The uncertainty for a piece of apparatus is either printed on the apparatus ex:

If a balance can measure to two report places 0. An exception to the uncertainty being science the smallest instrument value is when using a stopwatch. According to the display you can measure time to the nearest th how a write 0. In IB Biology, how bars should also be included in your graphs. Presentation Tables and Graphs You report show graphic representation of your processed data. Also make sure:

State a conclusion, with justification, based on a reasonable interpretation of the data: Ensure that you quote any quantitative results in your guide even if how quantitative results science mentioned elsewhere in your report. Draw write from them. Remember a guide can only report supported or refuted. This may be quantitative how values, manufactures claims or established theories. If you are comparing quantitative results express any difference between your value and the literature value as a percentage of the literature value. You need to show that you understand how your results support or invalidate your hypothesis.

Evaluation Evaluate weaknesses and limitations. Do this by analyzing your sources of error. Distinguish between systematic and random errors. Complaining about not having enough time or being disorganized has nothing to do with how procedure. You need to suggest a minimum of 3 significant improvements. Anything less will result in a partial.
