You should always consult your assignment guidelines to see if your instructor has specific requirements for the acknowledgments section. However, there are some common elements that are typically included in acknowledgments.
First, you might thank any individuals who have directly contributed to your work. For example, you might thank a mentor or supervisor for their guidance, or a friend or family member for their support.
Secondly, you might mention any organizations or funding bodies that have supported your work financially.
Finally, you might thank any other individuals who have indirectly contributed to your work, such as colleagues or fellow students.
If you're unsure about what to include in your acknowledgments, it's always best to err on the side of inclusion. Acknowledgments are not usually very long, so you don't need to worry about making them too detailed. Just a few sentences expressing your gratitude will suffice.
