Engineering Project Team: el Polo Loco

What are we doing?

Design/ Equipment

• Equipment: Two solar panels, a portable radio, Lab Pro, and a microphone

• We sent up a lab pro with microphone attached to ear phones that were attached to the solar paneled radio.

Expectations/ Hypothesis

• We expect that as the balloon climbs to greater heights the radio will begin to get louder

• We also expected that at every altitude stop we will receive better frequency.

Today’s Procedure • We attached our wires from the

solar panels to the radio• Then we hooked up a microphone

with the Lab Pro • We taped the microphone to the

earphones • Then turned everything on and sent

it up
