What happens to the weight of a piece of paper that is cut in half, then fourths, then eighths, then sixteenths?

• It weighs less the more times you cut it.

• It weighs the same even though it's getting cut.

• It weighs more because you're making more pieces.

• The paper is going to fly away so why try and weigh it.

Water is being boiled in a glass beaker. Eventually the water appears to disappear. What happened to the water?

• It absorbed into the beaker.

• The water didn't disappear, it changed forms.

• The water disappeared because the beaker weighs less

• We need to find a truck that can haul sand to prevent damage

• We need to design a solution and we only have $500 and 1 week.

• We need to first study the effects of erosion in other towns.
