Here is a reading on states of matter along with its accompanying vocabulary-building and comprehension worksheet.
Once again from the Intellectual Devotional series, this is a good general introduction to solids, liquids, and gases, and their molecular behavior. The reading and worksheet are in Microsoft Word, so you can edit and manipulate them for your needs. I’m not a science teacher, so I’m not sure why I wrote this. Probably because I had a couple of, uh, free days during the pandemic.
If you find typos in these documents, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
