Lena zeros the scale with an empty bowl, then measures dry beans in steps of 100 grams. Children can count ten colorful tokens and see why 1000 g and 1 kg describe exactly the same mass.

Mass

Mass measures an object’s inertia, its resistance to a change of motion, and is measured in kilograms. Weight is the gravitational force on an object, not its mass.

Song lyrics
Combien de grammes dans un kilogramme ? Lena pose un bol en verre sur la balance Le bol vide, elle appuie sur zéro Puis les haricots secs tombent dedans À chaque cent grammes, elle lit l'écran Et pose un jeton coloré à côté Mille grammes font un kilogramme C'est la même masse, écrite de deux façons Le gramme et le kilo sont ses unités La quantité de haricots ne change pas Cent, deux cents, trois cents brillent à l'écran Elle verse jusqu'au palier suivant Dix jetons colorés forment une rangée L'écran s'arrête sur mille grammes Elle change d'unité : un kilogramme Mille grammes font un kilogramme C'est la même masse, écrite de deux façons Le gramme et le kilo sont ses unités La quantité de haricots ne change pas Les haricots glissent dans un sachet transparent Elle écrit : un kilo équivaut à mille grammes Puis Lena lève fièrement son paquet Dix fois cent, cela donne mille Mille grammes font un kilogramme
Language version lyrics
How many grams make one kilogram? Lena sets a clear bowl on the scale While it is empty, she presses zero Then dry beans patter into the bowl Each hundred grams, she checks the bright display And sets one colored token by the scale One thousand grams—one kilogram The same amount, written two ways Grams and kilograms are units of mass The beans stay exactly as they are One hundred, two hundred, three light up She adds more beans to reach each hundred Ten colored tokens now make a row The display stops at one thousand grams She switches units: one kilogram One thousand grams—one kilogram The same amount, written two ways Grams and kilograms are units of mass The beans stay exactly as they are The beans slide into a clear bag She writes: one kilogram equals one thousand grams Lena lifts her finished pack with pride Ten times one hundred makes one thousand One thousand grams—one kilogram
