Science
Ariana watched YouTube videos about how atoms rearrange during phase changes and then she observed three hands‑on experiments. She saw liquid ice lollies freeze into solid sticks, watched an ice pole melt back into liquid, and observed water boil into steam that condensed on a cold mirror, forming water droplets that fell. Through these observations, Ariana recognized that temperature influences the movement of atoms and that matter can shift between solid, liquid, and gas states. She articulated the sequence of changes and linked the visual evidence to the scientific explanations she had seen.
Tips
1. Conduct a temperature‑tracking chart where Ariana records the exact temperature at which each state change occurs using a kitchen thermometer. 2. Create a story‑telling activity where she personifies water particles and narrates their journey from solid to gas and back, reinforcing the concept of energy transfer. 3. Set up a simple condensation collector (metal lid with ice) to capture water droplets, then measure the amount collected and discuss real‑world applications like cloud formation. 4. Explore the role of pressure by gently squeezing a sealed bottle of warm water vapor and observing how it condenses faster, linking it to everyday phenomena such as steam irons.
