Exploring the Conservation of Mass in a Terrarium

Curtis Bowy introduces the concept of conservation of mass, highlighting public misconceptions. He demonstrates a simple experiment with seeds in a jar to show that mass is conserved, explaining that plants use existing matter like carbon dioxide to grow. The video emphasizes the interconnectedness of nature, illustrating how atoms from the past, like those from dinosaurs or Einstein, could be part of us today. Curtis concludes by inviting feedback to improve his channel.
