Mission Log 2:
1. Review camera angle(s)
1. Brainstorm guiding questions to
help design and build microexperiment.
2.Explore the 4 aerodynamic forces
of Lift, Weight, Thrust, and Drag
3.Define Buoyancy
4. Build a model of a weather balloon
to launch into the Troposphere.

Guiding Questions
● Looking carefully at
each groups
Thinking Maps from
the last lab, what
are some common
themes/ideas for
our experiment?

* Using the above question as
inspiration, start thinking about a
unique micro-experiment we could
build to help answer that question!

Explorations
in Buoyancy...
* What happens when we
place objects in water?
* Water and Oil...
* What are the implications?
Explorations in Buoyancy...
* Gas, Gas, Everywhere!
* ‘Weighing’ our options
* Creating buoyancy
Buoyancy in Action!
* What will happen if I
attach a payload to
my balloon?
* Lift and Weight
Team Challenge!
Each team has a kit full of all the
materials needed to launch a model
weather balloon!
Your team’s mission:
1. Fill balloon with Helium
2. Load Payload
3. Attach Payload and Parachute
4. Modify to create buoyancy
