Can you please help by providing an example to help my understanding of the question?

Description of the activity

Include as much detail as is needed for the reader to be able to imagine what was occurring. This section is descriptive rather than analytic. It is about recording what you saw rather than what you thought about what you saw. As a result, it is important not to include inferences about how the children felt or about the quality of the activity. For example, you might say,"The three girls continued to build a block tower. They talked about it being as tall as a Dad, smiling at one another." As opposed to"The children had fun building a block tower. They thought it was as tall as a Dad, but it must have been a short Dad." You will likely include a reference that supports the mathematical content you observed. Please include photos to support your description.

I was considering doing an observation on a child who was building a block tower alongside another child. I am unsure if I am on the correct path.
