Light Wave Videos

Here are some supplemental videos about light waves that we did not have a chance to watch in class. One video includes an experiment you can try at home.

February 26th

Students took a quiz and we discussed and took notes on light manipulation. After discussing how light is manipulated by reflection, refraction, diffraction and absorption, students related those terms to how sound waves operate. During the final part of class students received an introductory lesson on dj-ing.

At this point of the Light and Sound unit, students have gone over the basic components of what they are required to learn (the GPS standard is listed in a previous post). Moving forward, students will start working on projects that will deepen their understanding of what is required in the standards.

Homework: None

**Today is the last day for students to take home their graded projects**

February 25th

Today students finished the Wavy Motions lab and we conducted a review session for Friday's quiz.

Homework: Study for the quiz.

Announcement: FRIDAY IS THE FINAL DAY FOR STUDENTS TO TAKE HOME THEIR GRADED PROJECTS. ANY PROJECTS THAT REMAIN AFTER SCHOOL IS OVER ON FRIDAY WILL BE RECYCLED!

February 24th

Today we finished discussing the human eye and we started a lab titled "Wavy Motions." During the lab students used slinkies to observe different types of waves and they recorded their observations in their lab books. We will conclude the lab tomorrow.

Homework: Study for Friday's quiz. The quiz will cover the electromagnetic spectrum and mechanical waves. Students should also know the definition of the following terms:
Reflection
Refraction
Transverse
Longitudinal
Medium
Wavelength
Crest / Trough
Compression
Rarefaction
Law of Conservation of Energy


Reminder --> Students have until Friday, February 26th to take home their graded Science projects.

February 23rd

Core 1 & 2 completed the Light & Sound worksheet in class and began taking notes about the human eye. Core 3 & 4 watched introductory videos and took notes about the human eye.

Homework: Students who did not complete the Light and Sound worksheet in class need to finish it as homework. Due Wednesday.

February 22nd

Today we continued learning about mechanical and electromagnetic waves. Students took notes and watched several videos* regarding the different types of waves. Students also took an assessment regarding the energy concepts they learned in previous units. I will review how each class did and begin review sessions as necessary.

Last Friday I announced to the students that I was organizing the room and that they could take home their graded projects. Students have until Friday, February 26th to take home their projects. Any remaining work will be recycled this upcoming weekend.

Homework: None

*the videos are attached in previous posts.

February 19th

In Cores 1 & 2 students finished viewing the introduction to Light & Sound powerpoint. In Cores 3 & 4 students completed an activity worksheet about electromagnetic and mechanical waves.

Homework: Students who did not finish the in-class work need to complete it this weekend. Due Monday.

February 18th

Today I introduced the new unit: Light & Sound. We discussed the GPS associated with the unit (listed below), students wrote down the unit vocabulary (also listed below, and we briefly talked about electromagnetic and mechanical waves. During the last part of class students used their textbooks to locate definitions of the unit vocabulary words.

Homework: None

Unit GPS
S8P4. Students will explore the wave nature of sound and electromagnetic radiation.
a. Identify the characteristics of electromagnetic and mechanical waves.
b. Describe how the behavior of light waves is manipulated causing reflection, refraction, diffraction, and absorption.
c. Explain how the human eye sees objects and colors in terms of wavelengths.
d. Describe how the behavior of waves is affected by medium (such as air, water, solids).
e. Relate the properties of sound to everyday experiences.
f. Diagram the parts of the wave and explain how the parts are affected by changes in amplitude and pitch.

Question: What are some of the characteristics of electromagnetic waves?

Standard:
S8P4. Students will explore the wave nature of sound and electromagnetic radiation.
a. Identify the characteristics of electromagnetic and mechanical waves.

February 17th

Today the students took a cumulative exam that covered the content they learned over the first 18 weeks of school. I will use the data from this exam to see what concepts we need to review over the next two months.

Introduction

Hello! My name is Ms. Black and I am the new 8th grade Science long-term substitute teacher at Inman Middle School. I earned my undergraduate degree in History at the University of Washington and I recently graduated from Georgia State University with a Masters in Teaching (specializing in middle school education). I have been living in the Atlanta area for almost 10 years, I have two children, and in my spare time I enjoy working with music.

Each day I will update this blog with a brief summary of what we did in class. Additionally, if there is any homework, it will be posted here as well.

Have a great day!

Ms. Black
