A better word
Students often begin framing concepts in the simplest possible language. Offering those opportunities to use more specific words, as well as new words with which they are gaining familiarity, reinforces the crucial literacy goal of developing vocabulary.
Teacher: Why did the runner’s heart rate increase?
Student: As the runner started to sweat they lost fluid from the blood making it thicker.
Teacher: Can you answer with a word different from thicker, one that shows scientific knowledge?
Student: As the runner started to sweat, some of the fluid they lost was from the blood making it more viscous and therefore harder to pump around the body.
Teacher: Very nice.
