A hypothesis is a tentative solution or explanation to test a certain idea. Thus it should be based on existing theories and knowledge. It has to be testable which means a researcher can support or refuse it through experimentation and observations. Also, hypothesis can propose a connection between unables

A good hypothesis must have these elements

1. Independent variable (IV) 2. Dependent variable (DV)

3. A prediction of what kind of eflect the IV will have on DV

In order to write a good hypothesis, you should take these steps

1. Read and collect observation about the problem 2. Look for possible causes of problems from your readings

3. Qutline possible explanations that you might want to study. 4. Evaluate whether your hypothesis could be confirm or disprove through experiment.

Here are some drafts that will serve as your guide in writing your hypotheses:

Example: If the speed of planaria reproduction is related to temperature, then planaria in lower temperature will reproduce mure slowly than thoxe in higher temperature.

2. If the

Example: If the temperature of a planria's environment is lowered, then the speed of planaria reproduction

Exmaple: A decreased temperature of a planaria's environment will decrease the speed of planaria

Directions:

1. Formulate a hypothesis on the given statements (3points). 2. Then, identify the independent variable (IV) by underlining it and underline twice the

dependent variable (DV). (2 points)​
