Answer:
1.) Because matter is made up of molecules, the behavior of matter is dictated by the behaviors of the molecules. If the molecules were different, matter would be different.
Example: water expands when it freezes
2.) Engage the audience — get them interested, give them a reason to listen. How?
Describe a scene or a character.
Tell a story.
Share a personal experience.
Relate to a recent event.
Piggyback on a previous speaker's remark or theme.
Point out something important about the audience or the current setting.

They got eaten or died cuz the lake was too cold
Once when I was like 10 I was playing is my friend katies backyard and heard very faintly somebody yell my name. I figured it was my mom so i pretened like i didnt hear it so i could play a little longer. My concience got the better of me and i headed back like 10 mintues later to find my mom, bandeging my little sister who go stung by muptile wasps. She yelled my name that day and for the first time i realised i was responsible for her, for the most part. Maybe somethinglike that but more dramatic and stuff. Hope you use it
