Science Stop: A Colorful Science Lesson

Last week,  Mrs. Yollis' and Mrs. Ranney's second and third graders teamed up with Mr. JR's high school chemistry students via a Google Hangout.   The high school students gave a fabulous science demonstration about color and light.
Mrs. Yollis met Mr. JR at the Google Teacher Academy in NYC,
  and they planned these science segments when there.
Mr. JR. welcomed the class! Everyone loved his new colorful hairdo!

 First Mr. JR. and his students taught the elementary students a great song about the rainbow. The seven colors of the rainbow are also know as the spectrum.

Have you ever heard of ROY G BIV?
What does ROY G BIV mean?

Next, the high school students demonstrated how to mix color pigment to make new colors! Watch and learn!

The students used a prism to split white light into the 7 colors of the visible spectrum. They used the word refract

What does refract mean? 

We ended the call with a chant about light!

Do you know any additional facts about light that you can add? 

What was your favorite part about the science lesson? 


  1. Thank you so much for letting my students hangout again! We hope you all had a lot of fun and learned something about light and color as well. Take care and happy holidays!

    Mr. JR

  2. @Mr. JR,

    My name is Daniel and I am in the second grade. There are third graders in my class, too. Did you like the third grade chant? Sadly I was not there. :-(.This how I make a sad face. I hope we can skipe with you and your class again.

    1. Hi Daniel! I'm sorry you weren't there. :-( I can do the sad face too! You taught me something new.

      I hope I get to see you when we talk again soon. We all can't wait!

      Mr. JR

  3. Dear Mrs. Yollis and class,

    What a fascinating post! It started me thinking and that can be dangerous because my comments can become too long to add here. Here is a link to an Extended Comment I write for you...

    Have a great winter break. I look forward to your shared learning adventures in 2013.

  4. Dear Mrs. Yollis and Mr. JR,

    Hi, I'm Chloe from Mrs. Yollis' class.

    I think light is exciting. One day I saw an incredibly light rainbow. I could see the begining and the end.

    The third graders light chant was really interesting. I can remember it, even though I'm in second grade.
    Her it is:
    "Light, is a form of energy. That travels throgh space, in a straight line."

    Are you interested in the third graders chant?


  5. Dear Mr. JR,

    My name is Bryce, and I am in Mrs. Yollis' class. I went to Hawaii over the break. While there, I saw seven rainbows! It was really neat to see them. I saw one every day! I had a very easy time seeing the color green in the rainbow, but yellow and surprisingly red were hard to see.

    I also saw lots of Hawaiians playing the ukelele in Hawaii. However, the Hawaiian songs were very different from the song you played on the ukelele.


    1. Hi Bryce. I love rainbows! They make me smile. You can't help but smile when you see a rainbow.

      The red color is hard to see because of the light from the sun. It's sort of like when you turn on a flashlight during the day. It's hard to see the light from the flashlight if the sun is shining brightly.

      The ukelele is so fun to play! Plus its easy for small hands like yours. Maybe one day you can learn how to play it.

      See you again soon!

      Mr. JR
