Fire lab
For this experiment my class heat up different types of elements and see the color they emit.
The scientific Method
Question: Why do these element emit different colors?
Hypothesis: If the wavelength of blue fire is high, does the height of the wavelength determine how hot it is? .
Materials: Propane, Methanol, lithium, boron, Sodium, Potassium, Copper, Magnesium, Strontium, Spiderman, and Burner.
Experiment steps:
1. We first gathered all the materials
2. Set up the propane tank and the burner
3. Pour the element on a metal stick
4. Pour methanol on it
5. Place the metal stick between the flame
Questions:
-We gathered all the material and used a Bunsen burner to start the flame with propane. The first Bunsen burner was contaminated with some of the past element that were burn on it. For some colored flame we saw some colors that shouldn’t have been there. We started by getting students to choose an element to burn on the Bunsen Burner to see the color it releases. After they chose their element andrew placed it on a metal stick and drop methanol on it. Then the student place the metal stick inside the flame. Some elements took a couple of secs to react and others were instant. After we were done admiring the flame andrew place the metal stick inside a cup of water and then hearing a sizzle sound. For each element the color it emitted was different. We learned that this is a method for forensics to obtain clues.
-When the elements got energized they emit a specific light that, but what happen inside the element’s atoms is that the electrons would move up a energy level because of how excited they were. After the excitement the electrons calm down and are in the relax stage state where it give off a wavelength or emits a specific light. Each element emits its own unique light. When forensics use this method to see what element it maybe, it is like using a sample of hair to find out who it belongs to.
-I don’t prefer working this way because I learn better in smaller groups. I feel like the more people are in a group the less knowledge I get to grasp. In this lab there was more watching than touching and I am someone that likes to connect with the activity.Then I can get more of my senses to interact and get a better experience.
