The more acidic a substance is the less oxygen it will produce when going through a chemical reaction. During the Lab “How Do Changes in pH Levels Affect Enzymes Activity”, the researcher conducted an experiment to test the effects that an acidic, neutral, and a base substance will have when combine it with hydrogen peroxide. The data table shows that HCL (acidic substance) barley produced any oxygen at all when it was combining with Hydrogen Peroxide. The pH level for HCL was 2.5; this level indicates that the substance was very acidic. When the H2O and NaOH were tested they produced more bubbles than HCL. NaoH produced a little more bubbles than HCL. The pH that NaoH produced was a 9, which is a base. H2O produced more bubbles than both substances;

To start out with a research where we use the experimental method, we first have to state what will be studied in our experiment. In this case, we will look at the problem of does sugar affect attention in small children. My hypothesis is that sugar will interfere with small children’s attention. The operational definition for affect attention will be measured by a learning lesson with the children. Where at the end of the lesson, children will complete a test from the subject that has been discussed during the lesson.

The value of 82.5mg per 250mL serving will then be divided by 10 in, order to have the serving size to be equal to that of the experiment (25.0mL), resulting in the amount of Ascorbic Acid in the juice to be 8.25 mg, which is less than the observed and calculated value of 10.73mg. Thus there appeared to be random error within the

crucial aspect to the experiment and the results such that the participants are to have

To make the experiment a fair test I will use the same amount of acid

The experiment will have the raw (original) data which could be qualitative or quantitative and it will most likely also have reworked (totals, %’s, averages, SD/SE) and organized data (tables, graphs, maps, charts). It might also include modeling (constructing a representation of an object, system, or process to show relationships) and a statistical analysis to show the spread of the data and establish the degree of significance.

The experimental method revolves around four main areas, which are participants, materials, procedures, and measures. Choosing participants for a study are

To keep this a fair test I have made sure that the acid used is the
