[Q]: Johnathan is trying to find two blocks of wood with the same mass for a project he is working on. He doesn't have a balance, so he makes a crude one out of materials he has on hand. He put a block of wood on either side and the block on the left side was at a lower level than the block on the right. Sarah is using a traditional balance to estimate the mass of her peppers. She wants to make 1 kg bushels to sell at the farmers market so she puts a 1 kg weight on the right side and the peppers on the left side. If the 1 kg weight is higher than the peppers does Sarah need to add more peppers or remove peppers?
