How is it moving?

     Over the past few weeks in the classroom we have been looking at how light moves and how we can manipulate the movement of light sometimes.  We took a disco ball light that ran on batteries.  When it was turned on, the ball would light up and spin and the children were able to see how the white light moved along a surface.

     We tried the same thing again but with a colored light.  This time we covered the table with paper and offered the children crayons that were similar colors to the light pieces on the spinning light.  We wanted to see if the children would make the connection between the crayons and the motion of the light spinning on the table.

     The children immediately started to draw large circles on the paper over where the light was spinning.  We noticed they were not making lines or dots, just circles and circular motions.  One of the children began to get frustrated when he tried to draw on the light on the table because the light continued to spin.  It might be interesting to repeat this lesson to see if he finds a strategy to use while tracing the light.        

  

     In the future, it will be interesting to see if the children would be more inclined to trace a light projected onto the wall or table that is stationary.  It will be neat to compare the actions of the children with a spinning light, and a stationary light.

Colored Light

     Over the past few weeks the children have been looking at light and how it can be various colors.  They have also been looking at how they can manipulate those various colors of light.  We have been working with flashlights a lot this term so I brought them out for the children again to use.  This time I put different colored cellophane over the light and taped it on so the children would be able to see different colors in the light beams when they used the flashlights.

     It was neat to see the reaction of the various children.  Some of the younger children were excited to just see that the light was different colors.  They would look at the light, and then look at how it shone on the mirror and wall.

     Some of the other children would take two different colored flashlights and shine them at each other.  I think some of them were doing this to see if they could get the colors to change or mix.  One of the children took two different colored flashlights and shone them on the wall next to each other, again, I think she was trying to see if she could change the colors somehow or get them to combine.  

     Because of these observations, I think it might be neat to use little sphere lights, meant for water arrangements, and use them with paint.  The children would still be able to see the light under the paint, but it would also give some of those children who were interested in mixing colors the opportunity to do so. 

November 2013

Hello Families,

                It is hard to believe November is already here!  We have been so busy in the classroom and have been learning so much.  We wanted to take a minute and invite all of our families to our Curriculum Night on Wednesday, November 13^th from 5:30-7pm.  Children are invited to come to school with their families to participate in hands-on investigations and look at documentation we have collected over the past few months.  Mrs. Stone, Ms. Rodegher, Ms. Salame, and Ms. Dunbar will be in the classroom to explain our investigations over the past semester.

                We also passed out a survey this week called Ages and Stages.  We are asking parents to fill it out and return it to school by the end of November.  This will give us and idea of what you are seeing at home and we can compare what we see at school.  At conferences in December we will talk about the survey.  If you have any questions about it please let us know.

                Thanksgiving this year is on Thursday, November 28^th.  There is no school this day, or the next day, which is Friday, November 29^th.  Have a wonderful few days with your families.

               As always, if you have any questions or comments please let us know.  Have a great day!

Origin of Light

              This learning group was inspired by our students interest in the observing the moon in the sky both at night and during the day. We then showed them a projected image of the moon in the sky on the wall, and this led to exposure to movies of the sun, stars and comets in space that were projected onto the wall. During other explorations, the students were also very interested in turning different lights on and off. These two observations of the children’s thinking has formed the big question, “Where does light come from?”

                When first introduced to the image of the moon, Casey and Mustafa identified it but were not as interested in it as they were when on the walks with their parents. So then I projected a video of the sun onto the wall and they were intrigued by the movement, the colors that they saw. At first, Casey identified it as the moon, and then he placed his hand on the wall and said, “Hot!” Jad made the connection between the projected video and the red cellophane that he then placed over his eyes to look through at the image. It wasn’t until we projected a video of stars that the children made the connection that they all give off light. When Connor saw the stars, he pointed up at the projected video and said, “Light!” When Abigail saw the projection, she looked at the wall and said, “Wow,” in soft whisper. 

                After this exploration, we went on a search around the building for different lights. We walked into the art studio and observed where the lights were and then in the teachers office. When the lights were turned off, it became very dark and the children found flashlights that they turned on and pointed at each other and on their bodies. When we explored the lights in the seminar room, they were very interested in where the light went and where it came from when the light was turned on and off multiple times. They would turn their heads in search for how it happened. This showed us that they the children knew the light came from somewhere, so the next exploration we decided to have them explore light sources that they can directly manipulate.

 We brought out the tap light that created stars on the walls and ceiling when turned on along with the other tap lights and flashlights. We had them in the darkest part of our classroom so when turned on; the children were able to focus directly on the light source that they manipulated. As Mustafa turned the tap light on and off, he would look around the room to observe what was happening when he turned it on and off. When a teacher would turn a light off, Mariana would say, “Turn light on!”

The children have explored how they can control where the light comes from and whether there will be light or no light. I wonder what their ideas are of how they get the light and where it comes from? Do they associate it with the on and off switches? Are they curious how light can come from all of these different things? I intend to further explore these questions with the children to gain a better understanding of their thinking.

                

Reflection of Light

We have been exploring with light using the flashlights and tap lights. We have been using these materials with mirrors and reflective surfaces to observe how the light changes when on a reflective surface. We have been observing how our reflection changes when light is on a reflective surface and how the light appears on it.

       

    We first placed the tap lights inside of the triangle along with the flashlights. The children sat next to the mirror and shone the flashlights inside the triangle, while others would sit directly inside of it. They seemed very excited about their reflection from the three different perspectives and would shine the flashlight onto the mirrors and on to their bodies.

          Another exploration that we did was we taped foil to the underside of the table so the children would crawl underneath the table with the flashlights and look up at their reflection. Some of the children crawled under the table without the lights and would bang on the foil. Others lay under the table on their backs and held the flashlight against the foil, then shone it onto the floor and back 
to the foil again. They were comparing how the light looked different on the two surfaces.

  

          Next, we stood the table up on its side with the foil still taped to the underside of it providing a new perspective. The flashlights were placed next to it and the children explored holding the flashlight onto the foil, then moving it so the light shone on their hand that was also on the foil. Again, they were comparing the appearance of the light on the two different surfaces.


      We would like to explore light next week on the surface of water using submersible mini tap lights in the water table. The students will be able to see the light reflected off of the surface of the water as well as underneath it. Students will be encouraged to manipulate the tap lights with the water.

Motion of Light

            The children in the classroom have been very interested in light and concepts related to light.  We have noticed while using the flashlights that the children were interested in how they could move the light from one location to another.  We wanted to expand on this idea and see what would happen if the children were introduced to a light beam they couldn't alter themselves.

 We found a neat video of a laser show.  During the video, the children were able to see laser beams that changed.  The colors changed, the amount of laser beams shown changed throughout the video, and the pattern and direction of the light changed also.  We wanted to see how the children would react to this since they themselves would not be able to change how the light was moving – they would just be able to respond to what they saw.

At first we tried the video on the large projector and showed the children on the wall.  The children seemed interested in the video but their attention did not last as long as we would have liked.  We think maybe since they have seen images and videos on the large projector in the past possible the novelty has worn off. 

We then tried the video on the laptop in our classroom.  This was much more interesting for the children and adults alike.  The children began to trace their fingers on the screen along the beams.  We wonder if they were trying to feel the beams or if they thought they could alter the direction and motion of the beams with their fingers, like with an IPad.  Their engagement was sustained for a very long time and the children were much more engaged in how the light was moving.  We also think that when the children saw the video on the computer the images were more clear and more engaging.

It might be interesting to see how the children would react to something on the IPad that they would be able to alter themselves.  We would like to explore this avenue with them and see what they think.

October 2013

Dear Families,

            Welcome to October!  We are so excited that all of the children seem to be adjusting to the classroom and our school day.  It has been nice to see happy faces not only during the day but when coming to school too!

            Ms. Dunbar and Ms. Salame have been working with Mrs. Stone and Ms. Rodegher to plan and implement lessons in the classroom.  We have noticed an interest in ideas surrounding light.  This is seen in shadows, how light moves, and even in the sun and stars.  We would really like to continue exploring and expanding on these ideas with the children.  To help with these investigations, we would love any donations of flashlights, rope lights, disco balls, or Christmas lights. 

            We are also inviting parents to check out our communication board and idea web at the front of the classroom.  We are collecting ideas here of what the children are interested in and what we want to pursue with them.  We would love if you had ideas to contribute or things you notice at home that might be related to what we are exploring in the classroom.  We will be updating our learning group information also which is located at the front of the classroom.  We will keep documentation of what the children are saying and doing related to specific ideas we are pursuing with the children.

            At the end of the month, we will have a Halloween Walk.  More details will follow as to specific times but we will be asking for donations of candy and other trick-or-treat items (pencils, playdough, goldfish crackers) which will be collected near the front desk. 

            As always, if you have any questions or comments, please don’t hesitate to let us know.  Have a great month!
