Balloon Zipline – Grade 4 and 5

Students in Ms. Tia’s grade 4 & 5 class were challenged with transferring a coin across a string using a balloon zipline. The students were given a plethora of materials, some they needed and some they didn’t. Then they had to eliminate the unnecessary materials, and build a zipline using the energy of the balloon to push the coin down the string. Afterwards, the class had a discussion on potential and kinetic energy and how both were used during the experiment.
