Concepts explained

Concept glossary ↗

Original explanations based on the cited sources.

Bacteria

Bacteria are single-celled organisms without a cell nucleus. Many are useful or harmless; only some cause disease.

Sources

Microorganisms

Microorganisms are organisms usually too small to see without a microscope, such as bacteria and yeasts. They are not all single-celled or disease-causing.

Sources

Lactic fermentation

Lactic fermentation converts pyruvate into lactate, allowing a cell to keep obtaining energy by breaking down glucose without using oxygen. Yogurt bacteria use this process.

Song lyrics
¿Qué esconde la tierra sobre mi mano? Vuelvo del jardín y me ruge la panza Yogur y frutas esperan en la mesa Pero quedan manchas oscuras en mi piel Al microscopio, hay bacterias en la gota Cada una es una célula que el ojo no ve Bacterias, células vivas diminutas Unas ayudan, otras pueden hacer daño Muchas solo viven a nuestro alrededor Mira su mundo, no temas a todas Ampliadas: puntos, bastones y curvas Viven en suelo, agua, comida y cuerpos Ciertas bacterias convierten leche en yogur Ese cambio es fermentación Otras pasan de manos sucias a la fruta Bacterias, células vivas diminutas Unas ayudan, otras pueden hacer daño Muchas solo viven a nuestro alrededor Mira su mundo, no temas a todas Agua y jabón hacen espuma en mis manos La espuma arrastra tierra y microbios Así pasan menos; no se van todos Bacterias, células vivas diminutas Unas ayudan, otras pueden hacer daño Muchas solo viven a nuestro alrededor Mira su mundo, no temas a todas Con manos limpias preparo mi merienda
Language version lyrics
What hides in the soil on my hand? Back from the garden, my stomach starts growling Yogurt and fruit are waiting on the table But dark earthy streaks still mark my skin In a drop, the microscope shows bacteria Each is one living cell, too small for eyes alone Bacteria — tiny living cells Some can help, and some may cause harm Many simply live all around us See their hidden world; don't fear them all Magnified: dots, rods, and bending shapes They live in soil and water, on us, in us Certain bacteria turn milk into yogurt That change is called fermentation From unwashed hands, others can reach the fruit Bacteria — tiny living cells Some can help, and some may cause harm Many simply live all around us See their hidden world; don't fear them all Soap and water bubble on my hands Foam rinses dirt and some microbes away Fewer can spread, though not all disappear Bacteria — tiny living cells Some can help, and some may cause harm Many simply live all around us See their hidden world; don't fear them all With clean hands, I make my colorful snack
