Homogeneous and Heterogeneous Materials Experiment Reflection


I examined sand, orange juice, soda water, lined paper and cloth. When observing the sand, I noticed that there were different shapes, sizes and color of the little bits of rock (sand). This became even more clear under the microscope, and I recognized that there were different types of rock in the sand. And the different types have different properties. Therefore, I classified sand as heterogeneous.
When observing orange juice, I noted that there was a mixture of pulp and liquid in the orange juice. Both the pulp and the liquid (juice) would have a different set of properties therefore, I classified the orange juice as heterogeneous.
When I observed soda water, I noted that there were many bibles on the sides of the container in which  it was contained. What was oddabout the soda water, is that is looked about the same when under the hand glass and the microscope. There fore I classified the soda water as homogeneous.
When observing lined paper, I noted that there were both the paper itself and the ink on the paper. Each having a different set of properties, I classified the lined paper as heterogeneous.
And lastly, when observing the cloth, U noted that there were both the cloth itself and a line of ink on the cloth. Both having a different set of properties, I classified the cloth as heterogeneous. However, when exempting a small piece of cloth without the line of ink on it, it appeared to be homogeneous, as I could see the fibbers of the clothier and it all looked the same.
Through the data I've collected, I can draw a few conclusions regarding the differences f homogeneous and heterogeneous materials. The heterogeneous materials are sand, orange juice and lined paper. The homogeneous materials are soda water and cloth. When examining the different materials, I noticed that the homogeneous materials looked the same throughout, while the heterogeneous materials looked different.
