A Experiment One
In our science lesson this week we did three experiments.
In the first experiment we had a bowl of water. We put an egg in it and it went to the bottom of the bowl. Then we put some salt in the water. The egg went to the top! It was really easy to do, so the teacher didn’t have to help us. When we got home, we taught our brothers and sisters how to do it.
B Experiment Two
In the next experiment we wanted to see how strong eggs are. We put some eggs in some sand. The teacher helped us because we had to be very careful. Then we put some books on top of the eggs. I was worried. I thought the eggs might break but they didn’t! It was amazing. After the experiment we wrote some instructions for it at home.
C Experiment Three
In the last experiment we didn’t need eggs, only sugar and water. We put cold water and sugar in a glass. Then the teacher gave us a glass of hot water with sugar. The sugar in the hot water disappeared more quickly than the sugar in the cold water. I knew why this happened because my brother did it last year. For our homework next week, we have to prepare a talk about it to the class.

I think Marie Curie was an important scientist. She didn't invent anything, but the discoveries that she made and wrote about have changed the world.
Her parents were teachers. They both helped Maria with her studies, but it was her father who was especially good at Maths and Physics. He let Marie use his microscope to look at microscopic beings. This made her very interested in science too. When she went to University, she met a man who was also studying Chemistry. His name was Pierre. After university they got married and spent most of their time in their laboratory.
Marie was very interested in medicine and wanted to make new medicines that would help treat diseases. Her sister, mother and father died when she was still young. This made her want to find better medicines. After lots of hard work she discovered two new chemicals which doctors were able to use as medicines. The chemicals she worked with were very dangerous. She kept working even though these chemicals made her very sick.
