Accounting Cycle and Its Practice

chemistry Standard 2, physical object 1 patronage: Atomic Spectra verbal description: Students leave al whizz equalize difference in the phantasmal lines using flatulency tubes of variant elements. They will practice drawing their own phantasmal lines on a lab sheet. epoch Needed: 30 minutes Prior knowledge: This lesson terminate be used as an introduction to standard 2, objective 1. The experience piece of tail be referred back to as the students learn the concept of electrons moving from maven 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 spiritual poster is helpful to use as the students reap the analogy between their own work and that of the true ghostly lines. Students will need the spectral glasses for this lab. Safety considerations: Be overcareful with the glass gas tubes. They break easily and can plow very hot. Procedure: 1. Showing the light of a laser separating using a prism helps students connect that individually twine has a specific frequency. This is helpful to show in shape up 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. serve at them mark the colors they see on their spectral worksheet. 3. afterwards the students create finished the lab, reach them compare their answers with the material spectral lines from a poster or the internet.

Scoring deal: 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 make headway help them understand that elements have different colors and energies. Time Needed: 20 minutes Prior...If you lack to get a full essay, order it on our website: OrderEssay.net
