Hello! I want to show how to make a Weighing Scales.
You know that one milliliter of water weighs one gram.
I poured a hundred milliliters of water in the first Cup. I weigh one hundred grams of lead in the second Cup.
Now I need a container of water, a cup should float freely in this container.
The water level in the container changed. And I put a mark on him.
Now I immerse the Cup with lead. The water level and the mark do not match, because I pulled one piece of lead weighing three and a half grams. And now all right.
You can weigh any weight changing quantity of water in the first cup if you want to weigh something bigger, you can to use a larger cup. it's all. Thank you for your attention. See you!
