About this listen

In this episode, we explore three curiosity-building stories designed for families and classrooms. Story 1: Mars rover “shadow selfie” • What a rover shadow can show about where it’s exploring • What craters are, and why rock layers inside them help scientists study Mars • How rover missions look for clues about Mars’ watery past Story 2: A rare northern quoll on a trail camera (Australia) • What a northern quoll is (a small marsupial) • How motion-sensing trail cameras work without bothering animals • How sightings help scientists understand and protect habitats Story 3: Cook a Sweet Potato Day (food science) • Sweet potatoes as storage roots (plants store energy underground) • How heat can change starches into sugars during baking/roasting • A simple observation game: notice changes in color, smell, and texture Parent/Teacher Corner These stories support conversations about how scientists observe the world (robot missions and field cameras) and how food connects to plant growth and energy. Discussion Questions 1) If you could send a robot anywhere to take pictures, where would you send it and why? 2) What’s one new way you’d like to try cooking a sweet potato, and what do you think it would taste like?
