Bacteria: Tiny Neighbors Everywhere | Educational Kids’ Song

◷ 2:34

What lives in soil, water, food, and on our bodies but is usually too small to see? This curious kids’ song introduces bacteria as tiny single-celled organisms, explores how certain bacteria help make yogurt, and explains how washing with soap and water reduces the spread of microbes.

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
Co kryje ziemia na mojej dłoni? Wracam z ogrodu, brzuch już mi burczy Jogurt i owoce czekają na stole Lecz na skórze widzę ciemne smugi W kropli pod mikroskopem są bakterie Każda to jedna komórka, dla oka za mała Bakterie — maleńkie żywe komórki Jedne pomagają, inne mogą szkodzić Wiele po prostu żyje wokół nas Zajrzyj w mikroświat — nie każda szkodzi W powiększeniu: kropki, pałeczki, łuki Są w glebie i wodzie, na skórze i w nas Pewne bakterie zmieniają mleko w jogurt Ta zmiana to fermentacja Inne z brudnej dłoni mogą przejść na owoc Bakterie — maleńkie żywe komórki Jedne pomagają, inne mogą szkodzić Wiele po prostu żyje wokół nas Zajrzyj w mikroświat — nie każda szkodzi Woda z mydłem pieni się na dłoniach Piana zmywa brud i część drobnoustrojów Mniej ich przeniosę, choć nie znikną wszystkie Bakterie — maleńkie żywe komórki Jedne pomagają, inne mogą szkodzić Wiele po prostu żyje wokół nas Zajrzyj w mikroświat — nie każda szkodzi Czystymi dłońmi szykuję przekąskę
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
