This week in our Inquiry lessons, we explored the fascinating process of how clouds are formed. Students were highly engaged as they moved from learning the theory to observing the process in action through a hands-on experiment.

One of the highlights of the week was our “Cloud in a Jar” experiment. Using simple materials—a glass jar, hot water, aerosol (hair spray), and ice cubes—we recreated the conditions needed for cloud formation. First, we poured hot water into the jar to create warm, moist air. Then, we introduced aerosol spray, which acted as tiny particles in the air. Finally, we placed ice cubes on top of the jar to cool the air inside.

As we observed closely, a cloud began to form inside the jar. This helped students clearly see how clouds are created when warm, moist air rises, cools, and condenses around small particles in the atmosphere.

To deepen our understanding, we also tested what would happen if one of the key elements was missing. In our second trial, we removed the aerosol spray. Students were surprised to discover that without these tiny particles, the cloud did not form. This led to meaningful discussions about the importance of condensation nuclei—small particles in the air that water vapor needs to condense into clouds.

Through this experiment, students not only observed cloud formation but also developed their scientific thinking by making predictions, testing ideas, and reflecting on the results.

In addition to this, we also created our own mini water cycle using a ziplock bag. Students poured a small amount of water into the bag, placed cotton near the opening, and then sealed and taped it onto a sunny window. This setup allowed us to observe how heat from the sun causes the water to evaporate into water vapor. Over time, students noticed tiny droplets forming inside the bag, and the cotton becoming slightly wet—just like clouds in the sky.

Overall, it was a wonderful week of inquiry-based learning. Students practiced observing, asking thoughtful questions, and reflecting on what they saw. We are looking forward to continuing our observations after the weekend and seeing how our mini water cycle changes over time. It will be exciting to discover what new patterns and results we can observe next week! 🌦️

Ohanami!

Beyond the classroom, we also took time to enjoy the beautiful sakura blossoms before they began to fall. Students had lunch under the cherry blossom trees alongside other grade levels, enjoying the fresh air and gentle spring breeze. It was a wonderful opportunity to relax, connect with others, and appreciate the changing season together.
