About This Activity

Zoe unearthed fossilized corn shells beneath her family's taco stand.

Teacher Tip

Stack eight sheets of colored paper to model rock strata — label each sheet with one vocabulary word and its matching geologic time event, then have students 'erode' the top layers by tearing edges to visualize unconformity; connect each layer to a taco ingredient to reinforce the theme.

Vocabulary Words

STRATUMA single flat layer of rock, like one tortilla in a stacked pile.

FOSSILA hardened print or remains of an ancient organism preserved inside rock.

EROSIONWind or water slowly wears rock away, like salsa dissolving a crispy shell.

SEDIMENTTiny bits of sand, rock, or soil that settle and pile up over time.

EPOCHA named chunk of geologic time shorter than a period, like a lunch rush.

SUPERPOSITIONThe rule that older rock layers sit beneath newer ones, like taco toppings stacked up.

IGNEOUSRock formed when melted magma cools and hardens, like cheese solidifying on a hot taco.

UNCONFORMITYA gap in rock layers where missing time shows Earth's history was interrupted.
