mini-lab: Identify Compounds

Here is what different compounds look while heated up under a flame.

Here is a picture of our results:

I think that in order of the pictures, 1 is copper, 2 is Strontium, 3 is Sodium, 4 is Rubidium, 5 is Zinc, and 6 is Calcium.

Question 1: Each element has a different amount of electrons in its shells, and when they are heated up, they produce energy in the form of color, each element producing a different color.

Question 2: This color that is produced is related to the colors it produces in the form of a light spectrum. The colors that are apparent from the element’s spectrum are the same as the one in the flame test.

Question 3: See Above

Error analysis: I think that there could be left over, or residue of the previous elements on the wire which could have altered the overall color.

Questions

1 and 2 are on my table.

3 This is taken as an average and divided.

4 Many of the ones that I found were very similar. The only major difference I saw was that one group only had 57 pieces. (I think they ate most of theirs!)

5 They are taken as the average of the isotopes.

6 Most elements have isotopes, but not all of them. They range to 3 to 36 isotopes.

7 Some people ate the snacks which led to an error. This led to a difference of the isotopes. Next time, let’s hope our classmates try to stay on task and eat during their break.

let’s make a spectrometer!

Here is a pretty cool picture of my partner Jack Condrey looking into our spectrometer!

Here are our Light Sources:

Based on this experiment I have concluded that different light sources have different types of spectrums. In the first spectrum, the fluorescent light one, I identified red, orange, purple, yellow and green. This is different from the LED light spectrum, which is mainly green, red and yellow-orange. And lastly, the Sun’s spectrum is very different from all of them, because it is a blend of the colors of the rainbow. Based on this information, I can conclude that different light sources composed of different elements emit different types of light, that can be represented in our spectrographs. Because of this lab, I can further understand light and the properties that it has.

Dimensional Analysis, Derived Units and Density

When I was reading the modalities and doing the activities, I very much enjoyed the interactive Buoyancy Lab. I learned that different factors can change the buoyancy of an object. If you increase the mass and decrease the volume, the fishing lure will sink. If you decrease the mass and increase the volume, the fishing lure will float.

Another thing that I learned was a better understanding of how to convert units of measurement using Dimensional Analysis. This method is very efficient and takes little work to get an answer. For example:

One thing that really was impressive was in the video. Some person calculated how much force the atomic bomb was by just looking at a picture with a scale of 100 meters on the bottom. This person used dimensional analysis to calculate how much Tnt would equivalate the atomic bomb.

I also found it interesting that you can find the density if you have its mass and volume, you can find the mass if you have its volume and density, and finally, you can find the volume if you have its mass and density.

I also learned that these are the derived units for the metric system:

Intro to Chem Blog Entry

While I read the ck12 modalities I learned several pieces of information about chemistry.

I learned that there are many types of chemistry such as physical chemistry, organic chemistry, inorganic chemistry, analytical chemistry, and biochemistry. All of these fields of chemistry that cover a wide spectrum. I thought this was very cool because I did not know there were types of chemistry.

I also found out that the two worlds of the chemist are the macroscopic world and the microscopic world. I thought chemists only focus on small/microscopic things.

Another thing I found interesting was that dynamite was invented by Alfred Nobel in 1866. I didn’t know that dynamite was invented so early. I figured that it was a relatively modern invention. Below is a picture of dynamite back then, and a modern type. Related image

One thing that really caught my attention was that Robert Boyle started studying and making discoveries in chemistry in the 17th century. I couldn’t believe that people started making breakthroughs in this field as early as the 17th century.

Lastly, this page reminded me that chemistry is in many parts of our life. From the clothes that we wear, to the medications we take, and even in our food, chemistry and evidence of it are present throughout our lives.

Observing Dye Separation Lab

1 We can observe 4 different dyes/pigments: yellow, pink, purple and blue

2 I think some of the dyes have different properties such as the amount of dye, the densities of the dye, or the chemical that is in the dye. This may cause the dye to separate into different categories.

3 Many of our peer’s chromatographs are the same. I went beyond the normal experiment and tried using a Vis-a-Vis pen to examine what colors it had. It had a different color scheme than the dyes of the food coloring.
