Volcano experiment writing

 Have you ever done a Volcano experiment before and tried to make it erupt? Well… on Monday Kea did a Volcano experiment, everyone was so excited. First we had to fill out a piece of paper on what ingredients we need and how to build it, also to write some hypotheses about what we think will happen. In my group were Sulia, Manu, Fane and Faaseina. Later on, when we went outside the weather was colder than ice. It was like we were in Antarctica.

Next, we filled the tub with sand then we molded it into a Composite Volcano ours was really tall it was taller than the sky tower. Then Sulia, Manu, and Fane went to get some water because we built our Volcano really fast so we still had some time left so they went to get water so we could build a moat around the volcano it was hard to make because our sand was turning as hard as a rock.

After that, we put the water around the volcano and put a container at the top of our volcano. Then on a sticky note and a snapped pencil and made a mini flag. The mini flag represented the first kea volcano of term two because we were the first ones to finish building. 

Finally, we added a few drops of Food colouring. It looked greener than grass. Next, we added Dishwashing liquid and baking soda then we put in the vinegar and it started to bubble like a bubble bath. After that Mr To'oala did a science experiment for us with Diet Coke and mentos and it exploded. I wonder what would've happened if we used more of everything?

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!
