Monday- I went over the important reminders as seen at the bottom of this post. Students were split into four groups #1-4. Each group outlined a different section of Chapter 16 on Sound and Light (sections #1-4. After about 20 minutes, the students were put into new groups so that each group had a student who outlines each section. The students started with section 1 and had 5 minutes each to share the important points from their section. Everyone was adding to their outline as they covered all 4 sections so that each student had an outline for the entire chapter when they were done. Outlines were turned in at the end of the period.
Chapter 16 Sound and Light
1. Properties of SOund
2. Musical Instruments
3. Hearing and the Ear
4. Ultrasound and Sonar
S.2 The Nature of Light
1. Waves and Particles
2. The Electromagnetic Spectrum
S.3 Reflection and Color
1. Reflection of Light
3. Seeing Colors
S.4 Refraction and Prisms
1. Refraction of light
3. Dispersion and Prisms
Tuesday- Students will be participating in a Spectrum Demo.
Spectrum tubes concentrate a gaseous discharge in a narrow tube to produce a brilliant line source of light for spectroscopic work. Current is sent through the tube and this excites the electrons in the gaseous sample. When the electrons get excited, they jump up to a higher energy level away from the nucleus, but after a while, they lose energy and jump back down to their original level. When the electrons jump back down, they give off energy and we see it as a certain color of light. During this demo, you will be recording the various elements gas spectra.Students will using a spectrum to look at Argon, Neon, Oxygen, Hydrogen, Water Vapor, Krypton, Helium, Xenon, Nitrogen and Air. Students will be recording the element symbol, Color, and the Color with spectroscope. Students will also be answering hte questions:
Why does the sample of air match closely with the sample for nitrogen gas?
Why does the sample of water vapor match closely with the sample for hydrogen?
Wednesday- Bellringer #47 Students will observe a Rube Goldberg Machine (the gmae mouse trap) and write down four chain reactions that they observed. Students will take notes and have a discussion about who Rube Goldberg was and what he is known for. Students will watch some video clips about Rube Goldberg Machines- 1. Mythbusters Christmas Machine, and two Purdue University Machines (they try to break the world record every year).
Thursday- Students will be in the libaray using a website to build a Rube Goldberg Machine.
Friday- Students will be in the library using a website to build a Rube Goldberg Machine.
1. Journals are due on Monday April 30th with Bellringers #35-47
2. Binders are due in order on Thursday May 3rd. If your Binder is not in order I will not grade it.
