Friday: Trace your plate

At lunch, Rocket stares at his plate: rice, scrambled egg and orange slices.

"I can see the Sun in the rice and the orange," he says. "They are plants. But the egg?"

Raven thinks. "What do you notice about where eggs come from?"

"Hens," Rocket says. "And hens eat grain. And grain is a plant." He grins. "Still sunshine!"

Nova does a happy loop. "Great discovery," she says.

Every bite started with the Sun

Some foods come straight from plants, like rice, oranges and beans. Their energy came from sunlight the plants captured.

Other foods come from animals, like eggs. Those animals ate plants, or ate animals that ate plants.

Either way, the energy traces back to the Sun.
