Your conclusion paragraph should logically conclude your essay, just like your conclusion sentences logically conclude your body paragraphs. The conclusion paragraph should begin by restating your thesis, and then you should broaden back out to a general topic. End with a closing statement.
Restate your thesis
The first sentence of your concluding paragraph should restate your thesis.
Example: Restated thesis
Thesis: Some of the most impactful inventions of the nineteenth century that changed the way we live were the telephone, the bicycle, and plastic.
Restated Thesis: It is obvious that these three nineteenth-century inventions dramatically changed our lifestyles.
The thesis changed by implying the main points, instead of stating them directly. Even though the words were changed, the overall meaning did not change. Other ways to restate a thesis include reversing the order of the clauses or using different word forms (e.g., adjective to noun: essential>the importance).
Apply your thesis to general contexts
Connect your thesis back to the general topics you mentioned in your introduction.
Give a closing statement
Your concluding statement is very similar to the concluding sentence of a body paragraph except that you will not restate your main idea at the very end of your paper. Your closing statement can be a prediction, suggestion, or opinion.
