AN: People, just so you know, this isn’t exactly my typical post. This is a post about science and not science fiction. I will not be hurt in any way if you don’t read this. I just thought it would be cool to share this experiment.

On the last day of school, I was asked to do a science experiment and record some results over the summer for an after-school program called Schüler Experimentieren (Pupils Experiments). I decided to do an experiment on how the color of water can affect the temperature of it. My father will be helping me in some parts.

What we need:

  • Brains (if you didn’t know this, you obviously have none :p )
  • Food Dye (you can choose the amount of dye and as many different colors as you would like(be creative and tell me the results; I love your guys’ stories))we choose the rainbow)
  • Water
  • Containers (if you use glasses and set it outside, the water could evaporate at different rates)
  • Water Proof Temperature Sensor
  • Sparkfun ESP8266 Thing Dev Board
  • The Sun (you might not be able to pick it up at the store…) or a light

Our first experiment will be to fill multiple containers with the same amount of liquid but dyed different colors. We will plug the Temperature Sensor into our Sparkfun ESP8266 Thing Dev Board that comes with an app that, if you program it correctly, will show you your data, so that way we won’t have to record it on paper. Of course, I will share the results with you guys, hopefully, but no promises, every day. (I’m going away in August for almost the entire month in a week and when we get back there are only 2 days until school starts again. Sadly, we can not start the project before I get back, and this whole post will be at least a month in advance to when we start the project, so…)

My hypothesis for experiment 1: Blue or purple will absorb the most heat. I say this because black absorbs the most heat and blue and purple are very close.

Project number 2 will be 5 containers with the same amount of liquid and the same color except with different amounts of food dye. The point is to see which one absorbs the most heat. There is a lot of science that goes behind this, but I will explain as simple as possible.

Light waves create color and vibrate at different frequencies. They go up and down in the span of a second. If they go up and down a lot in the amount of a second (say, 1,000,000 times) then it creates more energy then a light wave that travels maybe 1,000 times per second. And with more energy comes more heat. Set that aside.

When you put dye in water, the water and dye are separate. If the color of the water is blue, then it vibrates at a different frequency then other colors. If a colored light wave that isn’t blue hits it, it’s absorbed into the color, and because of the energy, it becomes warmer (the added heat depends on the number of times it went up and down per second). The blue light waves, however, are reflected off to your eyes and your eyes go “It’s Light!” and your brain goes “It’s Blue!” and your eyes say “Okay!” and everyone is overwhelmed and you live happily ever after.

You think that was a long explanation? Ha! There a probably scientists that could go on about the subject for hours.

My hypothesis based on the information I just told you is the more food dye, the warmer. I say this because if there are more dye blobs, then there are more possibilities for it to absorb, and it can absorb more, so…

 

When we get the results I will definitely post them. It’d be cool if you guys would also try the experiment and comment about it.

Love y’all,

Chloe
