Writing variables and hypothesses
What about them?
i don't even understand them and i have to make up 4 variables and hypothesses about independent and dependent variables

Study this. If you still have questions, post a specific one and tell us exactly what you don't understand.

Variables and hypotheses are important concepts in research and experimentation. Let me explain them to you.
Variables:
In research, a variable is something that can change or vary. There are two main types of variables: independent variables and dependent variables.
1. Independent Variable:
The independent variable is a variable that researchers manipulate or control. It is the cause or the factor being tested in an experiment. This variable is often denoted as "X" or "IV" and is deliberately changed or varied by the researcher.
For example, if you are conducting an experiment to study the effect of different amounts of fertilizer on plant growth, the amount of fertilizer applied would be the independent variable. You could have different groups of plants receiving different amounts of fertilizer (e.g., 0g, 5g, 10g).
2. Dependent Variable:
The dependent variable is the variable that is measured or observed in an experiment. It is the outcome or the response to the changes made in the independent variable. This variable is often denoted as "Y" or "DV" and depends on the changes made to the independent variable.
Continuing with the fertilizer example, the growth or height of the plants would be the dependent variable. By measuring and comparing the plant growth in each group, you can determine the effect of different amounts of fertilizer on plant growth.
Hypotheses:
A hypothesis is a statement that predicts the relationship between the independent and dependent variables. It is an educated guess about what you think will happen in your experiment. A hypothesis is often written in the form of an "If...then..." statement.
For example, if you believe that increasing the amount of fertilizer will result in increased plant growth, your hypothesis could be: "If the amount of fertilizer applied to plants is increased, then the plants' growth will also increase."
To make up four variables and hypotheses about independent and dependent variables, think about a topic or scenario you are interested in studying. It could be related to any field or subject - science, psychology, sociology, etc. Choose two variables (one independent and one dependent) that you can manipulate or measure in your experiment. Then, develop hypotheses that predict the relationship between these variables based on your assumptions or prior knowledge.
Remember, the independent variable is the one you change or control, while the dependent variable is the one you measure or observe. The hypotheses should reflect your expectations about how the independent variable will affect the dependent variable.
