Today in class we conducted 3 experiments with colored sugar, oil, water, and vinegar.

The 1st experiment we did was water and colored sugar, the solute was the sugar and the solvent was the water. Our hypothesis was: If we mix the water and colored sugar together the sugar will color the water, then the colored sugar would dissolve faster than in the oil. The first part of my hypothesis was confirmed because the colored sugar colored the water and the sugar lost its color, but the sugar did take a while to dissolve. The sugar all went down the bottom of the cup. The 2nd part of the hypothesis was unknown till the 2nd experiment.

In the 2nd experiment we mixed colored sugar water and oil together, the solute was the sugar and the solvent was the oil. Our hypothesis was: If we mix colored sugar and oil together, then the sugar will not color the oil, because it is thicker than water. The hypothesis was confirmed because the colored sugar did not color the oil. The sugar also did not dissolved in the water maybe because there is not enough water in the oil. In my 1st experiment, the 2nd part to my hypothesis was partially right, because the sugar dissolved in the water but not in the oil.

In my 3rd experiment we mixed vinegar and colored sugar, the solute was the sugar and the solvent was the vinegar. Our hypothesis was: If we mix colored sugar and vinegar together, then the sugar will not dissolve. Our hypothesis was denied because the sugar quickly dissolved into the vinegar a lot faster than the water. When the colored sugar dissolved it colored the water, but the vinegar made the color turn darker. These 3 experiment were really fun to do and I learned that liquids that are almost alike can have different effects on the same thing. I also learned that vinegar can change the color of things.

Isaac Newton was a great scientist. He made many invitations and discoveries most importantly he discovered gravity. Isaac Newton was born on January 4th, 1643, and lived in England. Sadly Isaac Newton’s father died two months before he was born. Isaac Newton’s mother got remarried when he was there years old and moved away, leaving him in the hands of his grandmother. Isaac Newton went to local schools, and at the age of twelve he got sent to King’s School in Grantham, England, were he lived in the home of a  pharmacist named Clark. Isaac Newton was interested in Clark’s chemical library, and laboratory and built mechanical devices for Clark’s daughter to enjoy, such as  a windmill run by a living mouse, floating lanterns, and sundials. Isaac Newton did very well in school.

Isaac Newton was trying to get into Trinity College, so when he tried to get into another school he failed, and went back to king’s school.  A huge point in his life was in June 1661 when he left home and went to Cambridge University, were Isaac newton entered a whole new life one were he was happy. When Isaac Newton arrived, the Scientific Revolution of the 17th century was already in full action. Isaac Newton was a british scientist at Cambridge University  for 16 years. In his first three years at the university Isaac Newton was taught the standard curriculum, but was more fascinated with the more advanced science and also spent a lot of his free time reading. He study hard and did hard work and that is how he became a world famous scientist.

How did Isaac newton discover gravity you may be asking, one day when he was playing he got tired and went to rest under an apple tree. Then before he new it an apple fell on his head. He wonder why it went down instead of up he studied for years until one day he figured out it was the force of gravity.

Isaac Newton was an amazing scientist who changed the world.  All though not everything has been discovered about him yet, from what we know he has done a lot that changed this world. From this project I learned a lot about him it has showed me that anything is possible you can  do anything you put your mind too. Because Isaac Newton did not come from much his father’s past away before he was born his mother left him but he achieved so much if you but your mind to it you can do anything you dream of.
