- 11. There are sixcomponents that you need to understand in scientific investigation. The 6 Steps are easy to remember with acronym of PDHECA. 1. P for Problem – stating a problem/ identifying a problem. A problem can be identified after a thorough observation or relying on existing data . In observing we have to use our 5 senses to gain information. After observation comes a question, which is now your statement of the problem. A good scientist will ask lots of questions.

E for Experiment –testing the hypothesis An experiment is a test that will prove or disprove the hypothesis. A good scientist will conduct an experiment more than once to double-check their work. In testing, variables are of great importance. A variable is any item, factor, or condition that can be controlled or changed.

C for Conclusion – Make a statement that accept or reject the hypothesis. The scientist will report his or her findings so that others may know what they find out.

- 17. In solving aproblem based on the given data or context of the situation, there are factors that should be considered. These factors are called variables. Variable are any factor or things, condition or trait that are changing in an experiment. In a scientific experiment there are three kinds of variables: 1. Manipulated variables or independent variable is a factor or condition that is intentionally changed by an investigator in an experiment. An independent variable is the cause. Its value is independent of other variables in your study.

Variable are any factor or things, condition or trait that are changing in an experiment. In a scientific experiment there are three kinds of variables: 2. A responding or dependent variable is a factor or condition that might be affected as a result of that change. A dependent variable is the effect. Its value depends on changes in the independent variable

Variable are any factor or things, condition or trait that are changing in an experiment. In a scientific experiment there are three kinds of variables: 3. A variable that is not changed is called a controlled variable. These factors are kept constant to determine any changes in the results (dependent variable) is caused by the manipulated variable.
- 20. Example Directions: Identify thePDHECA in the situation: Joanna wants to plant a tomato, but she wonders that tomato grows smaller and then die easily. So, she asked to the plant expert why her plant died easily, then she knows that she need to apply fertilizer. She used three fertilizer and named it fertilizer A, Fertilizer B and Fertilizer C. Joanna thinks that fertilizer A helps the tomato plant to grows taller that fertilizer B and C. To prove if her guess is correct, she tests the different fertilizers to the different set of tomato plant. After a week, Plant A grows taller than the others. Joanna’s guess was correct. So, in every tomato that she planted, she applied fertilizer A.

He gathers data on the internet, and he find out the different measures of sugar in a cake. Jeff thinks that more sugar will make a bigger size of the cake. He tried 3 different measures of sugar in a cake and after several hours, he finds out that whatever measures of sugar will used the size of the will be the same. So, he applied less sugar to his cake to also prevent his grandmother’s diabetes.
