Last Friday a group of HNI students including me went to EIT to explain our projects to judges. We entered our projects into school to get judged and my one got through. We all did different projects such as apple heat radiation, or smaller funnels lifting bigger objects. My one was about Cape Kidnappers Concretion Creations. so on Friday last week HNI set up their posters and were ready to talk to the judges.
The judges walked into the room and started judging the high schoolers then progressing onto the year eight's. Finally it was the year 7's turn they walked down the aisle finding the projects that they were allocated to. They asked questions and asked us to talk about our project. One of the questions were for me.... "How did the concretions form?" My answer was.... "Well 400 million years ago underneath the seabed were oil deposits and hydrocarbon gases bubbled through the cracks in the seabed. While doing so the hydrocarbon bubbles deposit calcite around the cracks forming the tube like concretions. Over time tectonic plates lifted the seabed up forming Cape Kidnappers. Then by weathering the concretions fell out of the cliff face and into the sea."
That was 1 of the things that I wanted to find out. I found by asking a geologist called Dr Bue. He explained how the concretions were formed. My other experiments were to replicate and measure how fast the concretions and mudstones found out at Cape Kidnappers were decrease. I used 2 sorts of weathering for my experiment: Physical & Chemical. The judges came back and asked us again about our projects.
Men started to come round stapling pieces of card board to our projects. One went to Oscar's the one next to me then mine then to Hannah's. We all looked at ours and the cardboard had Prize Winner on ours. The judges congratulated us.
I find out what get tomorrow on Thursday. Hopefully I'll do well!
