X= Students find the mass of a test tube of water, a fizzing tablet and a beaker. They add the tablet to the water, it bubbles and they collect the gas in a graduated cylinder. They mass the water and the beaker again and subtract this mass from the first. They divide the change in mass by the volume of gas they collected in the graduated cylinder
Y= Students mass an empty balloon, filled it with a gas and massed it again. They measured its volume by placing it in a full container of water that overflows. They collected the overflow and find the volume the balloon displaced. They find the mass by subtracting the mass of the balloon empty from it’s mass when it is full of gas. Then they divide the mass by the volume.
Which used the scientific method?

B. X, it used more accurate equipment
C. Y, it used the correct formulas
