Conditions of Use
On Thursday the 11th of August 2011 Cienna’s grandpa come to Oberthur Primary School to show area 11 some science experiments. He got us to call him Doctor Pa. Some of the chinese home stay students from Xing Zie Primary School came as well.
One of the experiments he showed us was one where he got a small strip of magnesium (abbreviation on periodic table: mg) and a lighted candle. First he rubbed it in sandpaper to make it silver. Next he got a student to pick up the magnesium with some tweezes and hold it a few centimeters away from the fire. Surprisingly, it went up in flames. Bart got selected for the experiment once but he placed it in the fire and the whole piece went up in flames. This one was my favorite experiment.
Another experiment was when Doctor Pa had a wooden stick to show that you were taller when you lying down than when you are standing up. Doctor Pa selected four students to measure. Chelsea was chosen first and she was the smaller than the stick so she was used for the experiment. She was about 1cm taller than when she was lying down. Next he chose Fanny, a chinese home stay student. Fanny was taller than the stick so she couldn’t be used for the experiment. The same thing happened to me but I was the same size of the stick. Next he chose Andrew C who grew 1 and a bit centimeters when he was lying down.
Another experiment was where Doctor Pa rubbed a comb though his hair and stuck it to a plastic spinning plate with blue-tac. He rubbed another comb though his hair and tried to push the comb with the comb without making them touch but it didn’t work so he gave up. He used magnets and they worked really well. He called lots of people up to do this one.
The science experiments were really fun and exiting but the learning experience was great. I would defiantly do it again!
