Course: Active Chemistry Grade Level: 10-11 Class Period Length: 49 minutes Teacher: Kirsten Brink School: Klein Forest High School District: Klein ISD E3 Project Instructional Plan Day 1 Topic Properties of the periodic table: Noble Gases Excitation of electrons Instructional Activities Student warm up will be about the characteristics of Noble Gasses. Students will be asked what they know about Neon. Teacher demonstrates the neon light bulb. Students will be asked to describe: ‘What does the neon look like before/after’? Then asked, ‘what happened’? Brief explanation of excitation of electrons (YouTube video 40 seconds). Students asked to summarize in their notebook. Students will then be asked about what they know about Helium, then what would happen if the Helium electrons were excited. Students make predictions. Show image of Helium light bulb. Ask students about the other noble gasesany predictions with what might happen. Ask students to use their own computer to look up the periodic table website to see the other Noble Gases. Ask students ‘what else might excite electrons’? Students then are asked to brainstorm a list of what might be example of excited electrons. (Hopefully fireworks, lasers, etc might come up.) If time permits, ask students about how exciting electrons may be useful. STAAR/ EOC/TAKS IPC 7 TEKS 112.35.c.2.H The student is expected to organize, analyze, make inferences, and predict trends from data Resources Neon light bulb Helium balloon(s) http://youtu.be/L 0UJhSvPE5A Student computers and www.periodictab le.com Course: Active Chemistry Grade Level: 10-11 Class Period Length: 49 minutes 2 Fire as a method to excite electrons 3 Excitation of Electrons Biologically Inspired Engineering 4-5 Student work time Teacher: Kirsten Brink School: Klein Forest High School District: Klein ISD IPC 7 Students will be informed that the light bulb from the previous day is an example of how electrons are excited by electricity. This day, students will be exciting electrons in a different way. Students do a typical flame test and asked to record data in their notebooks. Students will be asked at the end of the lab for practical uses of the salts in the flame tests (most common is fireworks). Students will also be asked how the electrons within the salts were excited Connecting with the previous day’s activities, students will then look at DNA gel electrophoresis (just the end result) as a demonstration of another way in which electrons can be stimulated.
