High-altitude balloon is a balloon,
filled usually with helium or hydrogen that ascends into an area called “near
space” or stratosphere. The most common type of high-altitude balloons are
weather balloons. Other purposes include use as a platform for experiments in
the upper atmosphere. Modern balloons generally contain electronic equipment
such as radio transmitters, cameras, or satellite navigation systems, such as
GPS receivers.
The mission of the
High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate
enabling technologies, and resolve critical acquisition, tracking, and pointing
(ATP) and fire control issues in support of future space-based precision
pointing experiments. The use of high-altitude balloons offers a relatively
low-cost, low-vibration test platform, a recoverable and reusable payload,
worldwide launch capability, and a 'near- space' emulation of the future space
systems operational scenarios.
More recently,
several university educators reported that they have been adapting
high-altitude balloon experiments for middle school and high school students. Launching
a high-altitude balloon is fun and exciting. The authors of this paper introduced
that they had been launching high-altitude balloons to engage students in
science since 2013.
In this paper, they
provided a brief discussion of their high-altitude balloon kit, the typical
data collected by their system, and discussed how the high-altitude balloon
experiment had been used to engage students in specific chemistry topics using
inquiry-based learning, as well as constructing knowledge using the collected
data from the balloon launch.
Through their
experience interacting with high school students, the authors have found that
the high-altitude balloon experiment is an effective tool for inquiry-based
learning to introduce chemistry topics including gas properties, elements and
molecules, heat capacity, thermochemistry, electromagnetic radiation, bond
breaking and formation, and atmospheric chemical reactions. Examples are given
to demonstrate how to incorporate the experiment in high school science
classrooms.
In conclusion,
through their interactions with high school teachers and students, they have
found that we can enhance the impact of the high-altitude balloon experiment by
incorporating the project into science classrooms.
