In this lesson we'll watch how adding weight changes what it takes to make the scale balance.
We start with nothing on either side. Write down what you see, and it goes into a table.
Then we'll add one g block to the left pan at a time. Each time, use the weights on the right to make the scale balance. When it balances, write down what's on each side in the boxes under the scale. When you get it right, we'll add it to the table.
At the end, we'll look at what the table shows.
