Term 3 Science Observation

In Term 3 week 4,Room 8 we’re studying plants,we decided to go further in our research .So we created an experiment of our own. My group was given a kumara  to observe for weeks. We made sure that the Kumara had water each morning and afternoon.We also made sure the water was clean. We gathered the appropriate materials:Two kumaras (one small and one large), four bamboo sticks(depending on the size of the cup and Kumara), one cup, and a plastic bowl for the big kumara .We poked all four bamboo sticks through the large Kumara and propped it on top of the plastic bowl.We put the small kumara in the cup without the bamboo to support it.We poured in water just enough to submerge the bottom of each of the kumara.We left the wet kumara near the window to indulge in the sun.The next day, we noticed that the big kumaras water had somehow vanished .So we watered it some more.On the way, whilst carrying the large kumara in it’s bowl we realised the bowl  was leaking.We grabbed another  bowl and sat the kumara with its leaking bowl inside.The day after that we noticed... it didn't change at all.It was a few weeks after that,that the miracle happened.I walked into school that morning and went to observe  the Kumara.Like a doctor with a patient .I screamed “Hallelujah”  !” “It’s grown fur.”Oh, wait I can see one small root sprouting.” This was exactly what me and my friends hypothesized.A few weeks later ,the root grew bigger and bigger.I discovered that it is possible for a small plant to produce more roots than a large plant.I also learnt that kumara can not only grow in soil and dirt.It can also grow in water too.The ending result was fur and one root sprouting.I felt shocked and delighted with the final outcome

  1. Very interesting and informative. Its very odd and awesome that kumara can grow under water.

    Keep up the great work Mavis.
