Using word clouds as a pre-reading activity

I'm always looking for different ways to teach my students, so I decided to use word clouds as a pre-reading activity. 

So how could you use these word clouds as a pre-reading activity?  

Identify the topic:  Easy right?!  What is this text going to be about?  What makes you think that?  The kids need to go beyond just saying seeds or plants.  They should be able to figure out that the first word cloud is for a book about a tiny seed growing into a flower, for instance.

Make inferences about the genre:  Students should be able to figure out that the texts are non-fiction or informational once they identify the topic.  

Set purpose for reading:  Following above, once identifying the topic and genre, the next natural step is to set a specific purpose for reading (to gather information about how a seed grows into a flower or plant).  Likewise, ask students to determine the author's purpose (to give information).

Access prior knowledge:  We do KWL's or concept maps before reading all the time.  Students looking at a word cloud of a text before reading would have a little bit more to go off of versus just a single word (i.e. What do you know about plants?).  The presence of other words will tip them towards other concepts they may not have thought of and their responses will be more detailed.

Develop questions:  Have students ask questions that they have about the concepts on the word cloud.  Another idea is to have students ask questions  that they believe will be answered in the text, even if they already know the answer (such as, What is a seed?).  Sometimes kids just need practice developing relevant questions. 

Introduce vocabulary:  While doing the above activities, assess how familiar your students are with the shown words and pre-teach necessary vocabulary that your students are not familiar with.  

As a side note, I made these word clouds using https://tagul.com/ but there are  many other generators you can use.
