Chemistry

Semester #1

Airplane Lab

For the airplane lab, I answered the question of how increasing the mass of a paper airplane affects the distance it travels. First, I created my hypothesis, which was that the more weight added to a paper airplane, the more drag there would be. After that, I gathered my materials, which were a paper airplane and 8 paper clips, and threw my paper airplane 5 times until all 8 paper clips were attached to the plane. I recorded my data each time, and the data showed that increasing the mass of a paper airplane doesn't change the distance it travels, making my original hypothesis wrong.

Smores Lab

For the smores lab, I answered the question of will chemical changes occur when making a smores treat. First, I listed the ingredients for marshmallows, graham crackers, and chocolate, and recorded them all. Next, I came up with my hypothesis, which was that there'd be a chemical change if I make a smores treat. Then, I started working through the lab procedures, which were breaking a graham cracker in half, unwrapping a chocolate bar and breaking it to match the size of the graham cracker, piercing a stick into the marshmallow and cooking it, and squeezing the marshmallow in between the graham cracker and chocolate to create the smore. For each procedure, I recorded if it was a chemical or physical change, and determined that there was a chemical change.

History of the Periodic Table

For the history of the periodic table project, we had multiple options on things to do like a tweet or a drawing, and I chose Mount Rushmore. I created a Mount Rushmore of chemistry, including Dmitry Mendeleev, Johann Dobereiner, Julius Lothar Meyer, and John Dalton. I picked Mendeleev because he ws the founder of the periodic table, I picked Dobereiner because he created groups, I picked Meyer because he created periodic law, and I picked Dalton because he created atomic weights.

Element Art

For the element art project, we had to create a drawing based off of an element that we picked. I created my drawing based off of the element aetinium, and I drew an X-Ray machine since aetinium is used in radioimmunotherapy and research. I also included the element number for aetinium, which was 89.

Bohr Model

For the Bohr Model project, I had to create a physical Bohr model based on an element. I created my Bohr model based off of the element Iodine, and I had to cut up 74 neutrons from straws and attach them to 4 rings using string.
