Can tomorrow be our last day?

Can tomorrow be our last day?

I am counting down the days with you, but sad at the same time. Yesterday we continued our unit of light waves by discussing how our eyes interpret light. Today we continue this journey by playing tricks on these “eyes” using optical illusions. These will seem like magic, but follow the laws of light. Before we enjoy this activity we have a few things to get done. Let us begin:

dots

  1. Last week we took a small survey on the Apple in the Dark. Please try this Again with your knowledge of light and light waves.
  2. Please take out your Homework and start working on Part C with your group. 
  3. When instructed we will be taking a small survey about this year and the use of iPads. We will work through each question together so please take your time.
  4. When you have finished with the survey and Part C you can meet me at the demo-table for some color tests and optical illusions.
  5. Homework tonight is to finish the following and bring a pencil tomorrow.

 

School is coming to an end!

School is coming to an end!

Only a little more than a week to go before the year comes to an end. We have had a lot of fun this, and you have actually learned both about Physics and Chemistry. This week we will finish our last unit on vision and light waves before ending the year. Even though school is almost over, you still will have grades this week so try to give 100%. Let us begin:

closeupeye

  1. Since we have been discussing both light and sound waves, I think it is time we compare the two. Please take out your Light Wave notes and take attempt part C
  2. Today we will be continuing our unit of light waves by discussing how the human eye and brain interpret light.
  3. When you have finished this you may obtain a copy of the Biology of the Eye Notes and start working on part A, B, and D. 
  4. When everyone is finished we will go through the answers as a class and watch the Brainpop video on Eyes.
  5. Homework tonight is to finish part A, B, and D and the following labs (if you have not finished already)
Ray Box?

Ray Box?

Yesterday we observed how focal point works with convex lenses. As you may or may not know, focal points occurs in both lenses and mirrors. Today you will have to the opportunity to observe this using a tool called a ray box. Hopefully by the end of the session today you will have a better understanding of how light travels and interacts with lenses and mirrors. Let us begin:

  1. If you did not complete the Lens Lab from yesterday please do so now with your partner. This would also be a good time to finish your Homework if you forgot.
  2. When you have finished with this we are going to do a little activity to practice with the ultraviolet spectrum of light. Read this Article with your group and be ready to discuss the topic. If you are done you can do the following: (answer as a group of 4)
    • Obtain a beed from the cup on the demo-table (one per person)
    • Observe the beed and physical characteristics
    • Hold the beed to the light around you. What happens?
    • Bring the beed near the window and let the sun shine on it. What happens to it?
    • Why do you think this occurred?
    • How is this related to the Electromagnetic Spectrum?
  3. If you would like you may create a bracelet using 3 (including your own) beads and the pipe-cleaners or string on the demo-table. Please do this while reading the refraction section of the Page.
  4. When ready you may login into the Ray Box Lab. Please come up to Mr. Holmer for the secret word. I will be doing this to check if you have completed the other steps.
  5. If you do not finish that is okay, you may finish on Monday. Your homework this weekend is to enjoy the 3-day weekend. Hopefully everyone has a good time and the weather is swell.
Working with lenses!

Working with lenses!

Even though we had shortened periods yesterday we were able to review both reflections and the electromagnetic spectrum. These are new concepts and will take some time to understand, but hopefully by the end of this unit you will be able to explain the topics. Today we will continue our discussion of light waves by discussing more about lenses. As mentioned earlier, lenses allow light to pass through them instead of reflecting. Today’s lab will introduce some new concepts while also bridging the concepts. Let us begin:

focal point

  1. To continue where we left off yesterday, open a Google Doc/Drive and share it with your group. You will answer the following questions about the Lazer Tag lab. 
    • What was most difficult about this activity? 
    • What did you find most interesting about this activity? 
    • What concepts have we been discussing are connected to this activity? 
    • If you could change one thing, what would you do to improve on your mirror layout? 
  2. When you have finished with the questions from yesterday you may do the following:
    • Read the Section on lenses then start working on the Lens Lab with your partner.
  3. When you have finished you may work on the following Homework Assignment (Notes)covering the topics of lenses. If you have not finished the lab you may do that tomorrow in class.
Lazer Tag!

Lazer Tag!

Yesterday you were all very talkative and a little off task. Hope we see a slight/major improvement today. With that in mind, today we will be continuing our unit on light waves by discussing the Electromagnetic Spectrum and reflection of light. Hopefully by the end of this session you will have a better understanding of the spectrum and how light reflects off of mirrors. Let us begin:

  1. Since a few of you forgot this yesterday, please take out a new page of notes (or your page titled Electromagnetic Spectrum) and include the definition of these two terms/concepts:
    • 7 levels of the Electromagnetic Spectrum
    • Draw the Electromagnetic Spectrum with the appropriate labels (for visible add the specific colors in the correct order) 
    • Definition of the Electromagnetic Spectrum
  2. When you have finished with this we will be going over the homework from last night and the information in this Document on the Electromagnetic Spectrum.
  3. Once finished we will begin with our Lazer Tag challenge. For this challenge you will be working with your group of 4 to hit your target (# 1-8) on the board using a laser pointer and 4 mirrors. These are the following criteria:
    • At least 4 mirrors used
    • Work in groups of 4
    • Laser pointer must hit target
    • Laser pointer must begin from group-table
  4. When you have finished discuss the following questions together as a group in a Google Doc. We will go through the answers when everyone has finished.
    • What was most difficult about this activity? 
    • What did you find most interesting about this activity? 
    • What concepts have we been discussing are connected to this activity? 
    • If you could change one thing, what would you do to improve on your mirror layout? 
We shall learn about the spectrum of light!

We shall learn about the spectrum of light!

Yesterday we investigated mirrors by building make-shift kaleidoscopes and observing the Law of Reflection. Today we will continue talking about mirrors, but also introducing the spectrum of light. Many of you have hard the term spectrum in regards to light from previous classes or when discussing technology. Today we will learn about this spectrum and how only a small fraction of light is visible. Let us begin:

EMSpec

  1. First thing is first, we need to complete the lab from yesterday. Take out the kaleidoscope sheet from yesterday and open up this Lab. If you have not finished, please do so now. 
  2. Open to a new page in your notes or notebook and title it Electromagnetic Spectrum. For the first set of notes I want you to write down all waves you know about. (example: water waves and radio waves)
  3. When everyone is done we will be making a kaleidoscope for you to take home. Try to make one using the following supplies: (I will help after you have attempted it)
    • 3 microscope slides
    • Electrical tape
    • Scissors
    • Brain
  4. While you are working on this we will begin watching a few videos to help with light and the electromagnetic spectrum. You may find your own, or use the following:
  5. Once finished with the videos in your notes (Google Doc or Notability) add the following information and correct titles:
    • 7 levels of the Electromagnetic Spectrum
    • Definition of the Electromagnetic Spectrum
  6. When we have finished the videos you will begin working on this Activity. You may want to use this Document for help.
  7. Help wanted: we are filming a music video clip for the talent show this Wednesday during lunch. If you would like to participate please bring in a pair of sunglasses and hoodie. If you have any questions please let me know. 
Hope everyone had fun at the dance

On Friday we continued our investigation of light waves. Hopefully many of you are starting to realize that both light waves and sound waves are similar, but at the same time different. Today we will finish up the light stations lab and practice using mirrors with kaleidoscopes. Some of you may know already, but kaleidoscopes use mirrors, which reflect light. Let us learn more about this now by following the directions blow:

tough

  1. Take a look at this Article and read through it. When you have finished take open a new page in Notability or Google Docs with 8-10 facts that you learned in regard to light, waves, or mirrors. 
  2. When you have finished doing this, open the Light Stations Lab from Friday and continue working on the questions with your group. When everyone has finished you may get up and use other stations.
  3. While doing this we will be showing a video about Light from Brainpop, any takers?
  4. When finished with this will be starting the Kaleidoscope Lab, which you will be completing on the back side of the paper you used in the beginning of class.
  5. Homework tonight is to finish the following questions:

    • Explain the reason for multiple images while looking through the kaleidoscope.
    • Explain the relationship between the angle of the mirrors and number of images viewed.
    • Predict how many images you will see at an angle of 10 degrees.
    • What is the equation/rule for figuring out the number of images for each angle? 
    • Write down 3 facts you learned from this lab you did not know from the reading or previous knowledge in regards to mirrors and light waves.
Stations that contain light!

Stations that contain light!

Yesterday we began our introduction of light waves by taking a small survey and reading through the notes. We will continue this journey today by taking a more depth look into how light travels and interact. Part of the class we will be finishing up the notes, while the other we will be interacting with mirrors and light at 4 stations setup around the classroom. The main goal of today’s activities is to better understand how light interacts with matter. Good luck!

Today we will begin to “see” the waves.

Today we will begin to “see” the waves.

Yesterday we finished the unit on hearing and sound waves. Today we shall continue our unit of waves and begin learning about light waves. Hopefully after last night’s homework all of you have a basic understand of how light works and how it may be different than sound. The main objective of today’s activities will to introduce light waves and how they interact with the world around us. Let us begin:

waves

  1. When we stared discussing hearing and sound waves you filled you wrote how you though hearing occurred. Right now I would like for you to take out your Biology of the Ear Notes and complete Part E. Please work by yourself, and you may use your notes sheet to answer. If you have lost your sheet, please write this down in either your notebook or type it up in an app on the iPad.
  2. When you have finished explaining how hearing occurs, take this small survey on the Apple in the Dark. You will be completing this on your own without any help.
  3. Now that you have finished the survey, you may obtain the Light Waves Note sheet from the demo-table and work on part A You may either use this PowerPoint or the Internet to answer the questions.
  4. Your homework tonight is to finish part B as a group of 4. You may either separate the workload or email answers. Tomorrow we will be doing a lab, so please have your homework done so you understand the topics. 
  5. Help wanted: we are filming a music video clip for the talent show this Friday during lunch. If you would like to participate please bring in a pair of sunglasses and hoodie. If you have any questions please let me know.

Did you “hear” about the quest today?

Did you “hear” about the quest today?

Hope everyone came prepared for today’s quest. Today we will be taking both the quest and common assessment on waves. Both will be graded and entered into the grade book……so please check your answers. Before we take the quest today we will do a group review and give you time to study with your partner. If you have any questions don’t be afraid to speak up. Let us begin:

  1. Before we take the quest you will have some time to review and study with your partner. You want to use the following to do so: 
  2. When everyone is ready we will take the Quest. You will need to clear off your desk and obtain a study-buddy from the demo-table.
  3. When you are done with the Quest you will be taking a common assessment on waves. This will cover both waves and sound waves. If you have any questions please speak up. For this assessment you will obtain the question packet and a scantron from the demo-table. Please fill out your name, instructor, grade, school, and student ID on the form. PLEASE DO NOT WRITE ON THE QUESTION DOCUMENT! 
  4. When you have finished both the quest and common assessment you may begin working on the homework. You will need to read/watch the following before answering the questions.
  5. After you have read and watched the video you may attempt this Activity. You may attempt the assignment as many times to reach the desired grade. You may need to reread or watch the video again. If you do not have Internet at home, you will need to come in before school, during lunch, or after school. Please talk to me if you have any questions.
  6. Help wanted: we are filming a music video clip for the talent show this Friday during lunch. If you would like to participate please bring in a pair of sunglasses and hoodie. If you have any questions please let me know.
