"Scientists use tools and careful observations—like robot explorers, trail cameras, and cooking changes—to learn about worlds, wildlife, and how food works."
Ask the class before watching:
"What is one tool (a camera, a robot, a thermometer, or even your senses) that could help you investigate something you’re curious about, and what would you try to find out?"
A crater is a big, bowl-shaped hole in the ground often made when something hits hard.
If a rover drives to the edge of a crater, it can look down at the rocky layers like a giant science bowl.
Minerals are natural materials in rocks that scientists can test to learn clues about a place.
Scientists hunt for minerals on Mars because they can hint that water once changed the rocks long ago.
A sanctuary is a protected place where animals can live more safely.
A wildlife sanctuary can help rare animals by keeping their habitat safe and giving them space to find food.
Starch is a kind of energy in some foods that your body can break down for fuel.
