APPENDIX

a) Observation : Salt dissolves easier in boiling water.

b) Inference : The amount of salt dissolvedincreases when the temperature

of the water increases.c) State the variables in this experiment

i. Manipulated variable :Water temperature

ii. Responding variable : The amount of salt that will

be dissolvedd) Identifying the problem:

Does increasing the water temperature affect the amountof salt that will be dissolved?
