Standard 2, physical object 1
Title: Atomic Spectra
Description: Students leave al whizz compare difference in the phantasmal lines using flatulency tubes of various elements. They will practice drawing their own phantasmal lines on a lab sheet.
Time Needed: 30 minutes
Prior knowledge: This lesson terminate be used as an introduction to standard 2, objective 1. The experience can be referred back to as the students learn the concept of electrons moving from one energy level to another.
Materials needed: Element gas tubes for argon, neon, mercury, hydrogen, iodine, oxygen, and air. new(prenominal) tubes can be used (just change the elements on the worksheet). An nuclear religious poster is helpful to use as the students reap the comparison between their own work and that of the true spectral lines. Students will need the spectral glasses for this lab.
Safety considerations: Be careful with the glass gas tubes. They break easily and can become very hot.
Procedure:
1. Showing the light of a laser separating using a prism helps students connect that individually color has a specific frequency. This is helpful to show in advance this lesson.
2. Show each of the gas tubes and give the students a s to put on their spectral glasses to see the lines. look at them mark the colors they see on their spectral worksheet.
3. afterwards the students create finished the lab, have them compare their answers with the real spectral lines from a poster or the internet.
Scoring Guide: wee-wee the students points for participating in the lab and finishing the worksheet.
Chemistry
Standard 2, Objective 1, Lesson 2
Title: Flame Tests
Description: After learning intimately spectral lines, the students will have fun lighting polar compounds on fire. This will further help them understand that elements have different colors and energies.
Time Needed: 20 minutes
