The document is a presentation on chemistry that includes an opening prayer, objectives, and activities. The opening prayer thanks God for the day and asks for guidance in learning. The objectives are to demonstrate understanding of the particle nature of matter and explain properties of solids, liquids, and gases based on this. Activities include a word hunt and determining whether samples are matter or not.

world around us.
Amen
