Teacher Model: A prewritten, genuine response for each of these might clarify the prompts for students and show how much you expect them to write in a response. Consider for your model using one word that has a science connection and one word that does not have an explicit science connection to encourage students to think broadly. The big idea is that everyone is a language learner and everyone has schema for noticing and working with words that have multiple meanings (multiple denotations and even multiple connotations).

Just Because: It may be important here to talk about why and how meanings change. Change may come in the form of a better understanding of that word. Or it may be a more nuanced understanding of the different meanings the same word can have in different contexts. This may be helpful to explore in the teacher model that is used.
