‘Tempo’ tissue paper is the toughest. Hypothesis
1.What is going to be changed? Brand of tissue paper (Tempo, Circle K, Vinda, Mannings) 2.What is going to be measured? The number of batteries that a wet tissue paper can support 3.What is/are kept constant? Same temperature of water Same size of tissue paper Same weight of batteries

1. Prepare 4 brands of tissue paper. Circle K Mannings Tempo Vinda
7. REPEAT Steps 2-6 for other three brands of tissue paper (Circle K, Vinda and Mannings). (2) (3) (4) (5) (6)
Safety precautions -Be careful not to spill the water out of the basin. - Put a towel under the tripod to avoid the drop of batteries to the bench.

From the table and the graph, we found that Tempo tissue paper can support eighteen batteries. So Tempo tissue paper is the toughest. Hence, our hypothesis is correct.
1.The time that the tissue paper soak in water was not exactly five minutes. 2.The force to put the batteries onto the tissue paper may not be the same.
1.We should pay attention to the time on the stop watch and take the tissue paper up when it reaches five minutes. 2.We should use the same force to put the batteries carefully.
