We launched into Day 4 by applying the scientific method to observe the water cycle in action. Students measured water temperature, poured equal amounts into two sealed bags, and placed one in a sunny window and the other in a shaded area. They developed hypotheses about what would happen and began recording their observations in a graphic organizer. This hands-on experiment helped students connect Earth science to space science, reinforcing how water behaves in different environments—an important concept for understanding life on Earth and beyond.

Next, we revisited our closest star—the Sun—by watching a video of fiery solar loops and discussing fascinating facts about its power and influence. Then, we shifted our focus to the moon, learning about its phases, surface features, and the historic moon landing. A favorite moment was our demonstration using a flashlight, soccer ball, and mirror to show how the moon reflects the sun’s light. This interactive activity helped students visualize how moon phases occur and deepened their understanding of light and shadow in space.

Our Cosmic Cadet expedition continued with visits to Mercury, Venus, and Mars! Students learned that Mercury is the smallest planet and watched a video of its rocky surface. They were fascinated to learn that it’s named after the Roman messenger god, which led to a discussion about mythology and how ancient cultures explained celestial phenomena. Students then wrote their own myths to explain a space phenomenon—each story was imaginative and unique! We then explored Venus, the hottest planet, and watched a video of its thick, cloudy atmosphere.

While learning about Venus, students explored the Golden Record, a real NASA project that sent messages into space for potential extraterrestrial life. Using the NASA website, students listened to greetings in many different languages and reflected on what messages they might send to space.

Finally, we landed on Mars, learning that its red color comes from iron in the soil. Students watched a video of the Mars Rover Opportunity and examined a model of a rover before beginning to build their own mini Mars Rovers using makerspace materials. Their creativity and engineering skills were on full display!

Day 4 was packed with science, storytelling, and space exploration. From experimenting with the water cycle to building Mars rovers, students are developing a deeper understanding of our solar system and the tools scientists use to explore it. We can’t wait to wrap up our journey tomorrow and celebrate all that we’ve learned!
