Stalactites and Stalagmites Experiment

 Stalactites and Stalagmites Experiment

Have you ever done a Stalactite or Stalagmite experiment before?

Yesterday Kea did a science experiment for writing,the science experiment was about seeing if we could create Stalactites or Stalagmites.

First we got given our ingredients. My group was given two containers and one cup. After we got given our cups,we added a few drops of food coloring.

Next Mel carefully poured hot water into the cup.Then we poured it in,we did 1 cup full per container.Then Whaea Sam came and put two heaped Tablespoons of Baking soda/Epsom salts.Then we stirred it to dissolve it.

Afterwards we twisted wool together, then put the two ends into the two containers. After that we put a piece of cardboard with our names on it then put it in between the two containers.

Finally we wrote our hypothesis on what we think would happen or not. Then we took our two containers and cardboard on the table in Waka tahi. My hypothesis was that I think that the baking soda will attach to the wool  when you pull it out.Two days later in the morning i checked on the containers and little crystals were appearing on the wool!
