Hello!
Sensory details are details that appeal to a person's senses (smell, sight, touch, taste, and hearing). A possible way that we could add sensory details in the sentence is:
English class is fun because we can listen to the friendly teacher and write in our notebooks.
The word "listen" appeals to the sense of hearing, because the narrator is hearing the teacher speak. The word "write" can appeal to the sense of touch, because the readers can imagine how it feels to write with the pencil.
I hope this helps answer your question! Have a great day!
