7. Procedures Devise a system to place the camera on so that it takes a picture from the same place every time. Attach a piece of graph paper to a 15” x 20” pressboard, make sure you can see graph lines with the camera. Place a flat surface above a dish and adjust it to eye level of the camera. Using hot tap water fill both jars almost to the top. Add one half cup sodium carbonate to each jar, stir until no more will dissolve.

16. ANALYSIS OF DATA My experiment didn’t test my hypothesis. Both times I did my experiment neither a stalagmite nor a stalactite formed, so I don’t know which would grow faster.

18. Some questions I have: How do the big rooms in caves get so big? Do other planets have stalagmites and stalactites like earth?
