Add a draw question
With the Draw question type your students can express their creativity, as they can draw whatever they want to answer the question. This type of question is not auto-graded, so you will have to correct it manually when the student sends their answers.
You just need to add the question statement and set the size of the drawing field (small, medium or big) to add this field to the worksheet.
Here you can see the question on the final worksheet and how the student can draw on it.
