How did the first life evolve?
◉ Small organic molecules to larger ones
◉ Chemical reactions start to make systems (ex:
photosynthesis)
◉ Formation of DNA, which can self-replicate
◉ Not in video—enclosure of systems of chemical

Vocab flash cards
You will be making flash cards that you will use to
study vocabulary terms.
You must include:
◉ Scientific/Textbook Definition
◉ Picture or Example
Vocab words:
Prokaryote, Eukaryote, Autotroph, Heterotroph
Change over Time
Add these terms to your notes:
◉ Catastrophism – Change only happens when
Earth has been affected by sudden, short-lived,
violent events – possibly worldwide. (not
plausible)
◉ Gradualism – Large changes are made slowly
and continuously.
◉ Punctuated Equilibrium – a period of very little
change (stasis/static) then a few rapid,
significant changes.
