This was the second day of hands-on science with our energy unit. While light will be covered in depth in January upon returning from the break, I am still tying it all in since there is a relationship, or correlation, between light and heat. This is what we did today and will also do tomorrow. With light, it involves absorption though I didn't mention it yet.
Then we did the experiment involving a correlation between light and heat. The class was split up into pairs of students. Each pair got a flashlight and a blank sheet of paper. I went around with my IR non-contact thermometer and took an initial temperature reading. The students recorded the number (to the tenths place....for example if the temperature was 71.3° then 71.3° was recorded rather than rounded to the nearest one).
Then, I went to an online countdown timer and set it for five minutes. When it was time, the students turned on their flashlights and held them about a fist's length above the paper, shining the light. The light had to be continuous and consistent with the distance. Partners switched off when needed.
After five minutes, I went around the room and took the temperature where the light is shining. They again recorded the exact number as a decimal and compared the results. Except for a few cases, almost every group saw an increase in the temperature. They then wrote a brief reflection on it.
This activity will be brought up in January when we go over the property of absorption. Below is a slideshow of the activity.
In social studies I had the students work on their brochures. Tomorrow we will get the use of the Chrome Books so that will help. I also set up a Google Classroom account. The url is classroom.google.com and my code is 8muc37t.
