MOST IMPORTANT SAFETY RULE I think the Most Important Safety Rule in the lab is not to play around with chemicals. Why? Anyone can be seriously injured including yourself.



IRENE JOLIET-CURIE FACTS Irene Joliet-Curie was born in Paris, September 12th, 1897. She first studied science in Paris and also worked as a nurse in World War I. Then, in 1925, she became a doctor of science. She did work on natural and artificial changes in the nuclei of atoms of the element, transmutation of elements and nuclear physics which proved to be important. After winning the Nobel prize in 1935 for chemistry, she made another discovery in 1938 which led to the discovery of uranium fission. Although her discoveries were good enough to win the Nobel prize, her discoveries do have a negative effect. Her work on nuclear would have helped armourers to build a more destructive weapons.



DEFINITIONS FOR SCIENCE EQUIPMENTS Experiment: A test on your hypothesis Hypothesis: An educated guess Beaker: A cup-like lab container Test tube: A cylinder tube that you test chemicals in Measuring cylinder: A cylinder tube that has accurate mL measurements so you can measure liquids Conical flask: Cone shaped bottle with a wide body

BEST THING I HAVE LEARNT The best thing that I have learnt is probably learning how to light a bunsen burner. I have learnt how to light a bunsen burner before because I have participated in Science Lab CCA but i never really remebered it. Now that I know how to light the bunsen burner, I can do some experiments at home and show off to my family. With the bunsen burner I am sure their are many more experiments that can be done. By learning science I can improve my knowledge and I am sure that will help me in the future. Lighting a bunsen burner is fun as well because it is really fun lighting matches, twisting the air hole and making heating flames/saftey flames. I don't think science is that hard but I know it can be very dangerous. I thought the exam was a bit hard but it was all about what we have learnt so it wasn't challenging. So far I am liking science.
