#2 Origin of Life

Scientific Reviewers: Professor Inge Loes ten Kate and Dr. Jim Ottelé.

If life found a way to begin on Earth, could it find a way somewhere else too? This investigation invites young explorers to tackle one of the most challenging questions in science: how did life actually begin?

Big Questions Your Child Will Explore:

The Difficulty of Clues: Why is it so hard to find evidence of life’s birth from billions of years ago, and why do fossils only show us part of the story?

Defining Life: What are the three essential parts—Boundary, Metabolism, and Evolution—that something must have at the same time to be considered truly alive?

Life’s Ingredients: Can simple gases and electric sparks create the building blocks of life before any living thing even exists?

The Chicken-and-Egg Loop: Which came first: the "recipe book" instructions (DNA) or the "machines" that read them (proteins)?

The Replication Threshold: How fast must a molecule copy itself to stay ahead of natural damage and stay "in the game"?

Evaluating a Birthplace: Which environments on early Earth—from primordial soup to deep-sea vents and volcanic pools—pass the scientific checklist for starting life?

Life from Scratch: We know many planets are habitable, but can life actually start from scratch on worlds like Mars or the moons of Jupiter?

The Big Challenge: In the finale, children design their own original planet, choose its hazards, and apply their scientific checklist to explain why life could begin there.
