⚡ Kuliso Cognate Callouts — Science Words You Already Know

Science has some of the strongest cognate connections between English and Spanish — many terms share Latin or Greek roots. Spanish-speaking students can use these shortcuts to crack science vocabulary faster.

Biology→Biología Same root, add accent

Organism→Organismo Swap -m for -mo

Energy→Energía Same root + accent

Hypothesis→Hipótesis H→Hi, add accent

Experiment→Experimento Add -o at the end

Classification→Clasificación -tion → -ción pattern

Adaptation→Adaptación -tion → -ción pattern

Ecosystem→Ecosistema Nearly identical

Why Bilingual Science Vocabulary Matters for Test Performance

59%

of ELL students score below proficient in science on NAEP

80%

of science words in English have Latin or Greek roots — shared with Spanish

better retention when new terms are anchored to known home-language cognates

Science exams test both content knowledge and academic vocabulary. A Spanish-speaking student who knows what fotosíntesis means has a head start on "photosynthesis" — they just need to recognize the connection. Without that bridge, they have to learn the concept and the foreign word simultaneously.

The -tion → -ción pattern alone unlocks dozens of science words: evaporation, condensation, classification, observation, adaptation. Once a Spanish-speaking student recognizes this pattern, vocabulary acquisition accelerates significantly.

Kuliso's AI tutor teaches science concepts in Spanish, then explicitly shows these bridges — turning cognate recognition into a learnable skill rather than a lucky accident.
