Airplane Lab

This lab was about testing the distance a paper airplane could fly with weights. The weights we used were paper clips and were perfect size and were able to be attached easily. We did 5 tests, we started with no paper clips and as the tests went on we add more weight. The results of the test was that we found a sweet spot of where having 4 paper clips made the plane fly the longest.

Smores Lab

In this lab we learned about physical and chemical changes. The main idea of this lab was to cook a marshmallow to the brown that you liked. We did this using a heater and some tin foil wrapped around the marshmallow. The tin foil is used to conduit heat. This took quite a while, mainly because the heat took a while to transmit through the foil.

History of the Perodic Table

from this project I created a diary entry about a element and it's properties. The element I had was oganessian which has the atomic number of 118. This element is not found naturally and can only be created in a lab. It belongs to the noble gases, yet it is still radioactive. I was created by 245 million electron nuclear reaction when combining to other elements.

Element Art

For this project I created an infographic about an element called Rutherfordium. My main idea for this to recreate the place it was made. For the information it has the element symbol and and it's properties. In total I liked how it turned out and I found this project quite fun.

Bohr Model

For this assignment I created the Bohr model of Rutherfordium. Each of the pieces of plastic straw is an electron, and the black string represents the rings. In the center is where all of the protons and neutrons are held, which is represented by the circle in the middle. In total I liked this roject even if it was simple.

How might cultural and historical contexts have shaped scientific discoveries in making the periodic table?

Cultural and historical contexts significantly influenced the development of the periodic table, shaping scientific discoveries through advances in chemistry, the evolution of scientific ideas, and the context in which these ideas emerged. The periodic table was shaped by the work of scientists like Dmitri Mendeleev, who is often credited with creating the first widely recognized version in 1869. Mendeleev's understanding of the periodicity of elements was influenced by earlier discoveries, such as John Dalton’s atomic theory, and the development of new technologies, like spectroscopy, which allowed scientists to study the properties of elements in more detail. Thus, the periodic table was not just a product of individual discoveries but of the historical and cultural currents that shaped the scientific community at the time.
