• Place each seashell on a balance to see if they have the same mass.

• Measure the length of each seashell with a measuring tape to see if they are the same length.

• Drop each shell into a graduated cylinder with water to see if they raise the water level equally.

Thomas and Julie wanted to find out which material would insulate their teacher's coffee cup in order to keep

the coffee hot for the longest period of time. First they wrapped her cup with bubble wrap and recorded the

followed the same procedure. After analyzing the data, they concluded the results were the same for both

materials. What could they do to make sure their results are valid?

• Use all the steps of the scientific method.

• Change the procedure and repeat the investigation.

• Use a different thermometer to measure the temperature.

• Keep the procedure the same and repeat the investigation.
