• Tell the teacher right away

• Ignore it if the spill is small

• Continue with the experiment

What is the main difference between mass and weight?

• Mass is affected by gravity, while weight is not.

• Weight is affected by gravity, while mass is constant.

• Mass can only be measured in space, while weight is only measured on Earth.

• Weight changes with volume, while mass does not.

You are tasked with measuring the VOLUME of an irregularly shaped rock. Design a step-by-step method using laboratory equipment to determine its volume accurately.

• Use a ruler to measure all sides

• Place the rock on a balance and calculate the volume using its mass

• Submerge the rock in water using a graduated cylinder and measure the displaced water

• All of these
