Recognize dragonflies as formidable aerial and aquatic predators - Answer✔one of first to fly,
massive 3 ft wingspan, larvae live in water for 3+ years
Identify dragonflies as ancient insects (when, what, why) - Answer✔carboniferous (300-360
mya), a long time, have evolved over time, larvae fearsome predators bc of invisible mask that
grabs things... first animals found 600 mya but all tiny marine so one of first bigger animals
Identify huge body size as the outstanding characteristic of animals (including dragonflies) in
the carboniferous - Answer✔possible: more carbon, o2, prey was bigger, no predators, more
energy demands, natural selection
why: more o2 in air allowed to get bigger and no other predators in air
Describe the life stages of dragonflies - Answer✔egg> larvae> adult dragonfly
Develop more than one hypothesis for why dragonflies were so big - Answer✔1. More oxygen
in atmosphere during the carboniferous
2. More prey available and less competition (less predators)
3. Large size helped them hunt?
Evaluate these hypotheses based on your explorations in EarthViewer - Answer✔-changes
during carboniferous: o2 goes up in the carboniferous then decreases after
Dragonfly size - Answer✔-high O2 levels in carboniferous allowed them to grow big
-later in history predators constrained the max size
Rank the importance of team-working skills, content knowledge, communication skills, learning
skills, ... for employers and graduate school admission - Answer✔most: team-work
least: content knowledge
