This resource provides a hands-on investigation into the relationship between gas temperature and volume through a series of engaging activities that explore cold and hot temperatures' effects on a balloon. Students are tasked with observing quantitative changes as the balloon is placed in ice water and hot water, allowing them to visually understand how gas particles' kinetic energy influences their behavior in different temperature settings. Additionally, insights on making predictions based on scientific reasoning and comparing those predictions with observed results encourage critical thinking and a deeper understanding of gas laws. The activities promote student inquiry through sketching, describing observations, and connecting theoretical concepts to practical experiments.
