Ola and her dog discover why it feels cooler beneath a tree and how trees support people, animals, and the neighborhood. This cheerful children’s song also introduces leaves, oxygen, roots, and rain while showing that a sapling needs the right place, regular care, and time to grow.

Song lyrics
¿Por qué quema el banco bajo el sol?
El perro de Ola busca sombra en la plaza.
La copa del árbol frena parte del sol.
En tierra más fresca descansan los dos.
Canta un ave; un insecto visita flores.
La lluvia breve cae entre las raíces.
Sujetan el suelo; el agua se infiltra.
Arbolito, gran ayuda.
Crece despacio, año tras año.
Da sombra a la gente, refugio a la fauna.
Ayuda a todo el vecindario.
¿Cómo ayudan sus hojas a que crezca?
Usan luz y agua para hacerlo crecer.
También toman un gas que está en el aire.
Se llama dióxido de carbono.
Y al hacerlo, liberan oxígeno.
Arbolito, gran ayuda.
Crece despacio, año tras año.
Da sombra a la gente, refugio a la fauna.
Ayuda a todo el vecindario.
Ola y un adulto buscan un buen lugar.
Acomodan las raíces y echan tierra.
La riegan y cuidan en cada estación.
Arbolito, gran ayuda.
Crece despacio, año tras año.
Da sombra a la gente, refugio a la fauna.
Ayuda a todo el vecindario.
Años después, la familia come a la sombra.
Flores dan alimento; ramas guardan nidos.
La planta ya ayuda al vecindario.
Language version lyrics
Why is that sunny bench too hot to touch?
Ola’s dog seeks shade across the square.
The old tree’s crown blocks some of the sunlight.
Cool earth below lets both of them rest.
A bird sings; an insect visits flowers.
A quick shower runs down among the roots.
They hold the soil and help the rain soak in.
Little tree, such a big help.
Growing slowly, year by year.
It gives us shade and animals a home.
It helps the whole neighborhood.
How do green leaves help a tree to grow?
They use sunlight and water for its growth.
They also take a gas from the air.
Its name is carbon dioxide.
As they do, the leaves release oxygen.
Little tree, such a big help.
Growing slowly, year by year.
It gives us shade and animals a home.
It helps the whole neighborhood.
Ola and a grown-up choose the right place.
They spread the roots and cover them with soil.
They water and guard it through each season.
Little tree, such a big help.
Growing slowly, year by year.
It gives us shade and animals a home.
It helps the whole neighborhood.
Years later, her family picnics in its shade.
Flowers feed insects; branches shelter nests.
That little sapling now helps the neighborhood.
