“The heavens declare the glory of God; the skies proclaim the work of his hands.” Psalm 19:1
We don’t for sure what the sky was like in the days of creation. Scientists speculate that the atmosphere was a lot thicker because of what it says in Genesis 1:6-8 about there being water above the expanse called sky.
Even so, I wanted to teach my children about what the sky is and why, today, the sky is blue.
First, we made a rainbow because part of the reason the sky is blue is because of light. Light has a combination of all the colors of the rainbow. You can also explain a little bit about the different layers of our sky with this craft too. I really like how it combines aspects from our Day 1 of the creation story.
We used Q-tips to paint our rainbow. It really helps cut down on mess and is easy to clean up. I had the children put another piece of paper over their copy-work sheet and start painting with one color at a time. We moved the paper down to reveal a clean spot on our sheet and added another color until our paper was filled with the colors of the rainbow. Yes I forgot green, but stuff happens 🙂
Why is the Sky Blue Experiment
Then I explained what happens to all those colors when the light hits the sky with an experiment. We used my science experiment printable that you can find here to record our findings.
We used milk to represent the gas and particles that are kept in our sky because of the atmosphere. I explained that if we didn’t have an atmosphere, the sky wouldn’t be blue. It would be black. Just like you see pictures taken on the moon, even with the sun shining.
We dimmed the room so the light from outside wouldn’t shine on our water. First, we shined the light on the water without adding any milk to see what it looked like. Then, we added a very small amount of milk to the water and shined a light on it. We tried looking at it from all different angles. When you looked at it from the side with the light shining to the right or the left, you could really see the blue tint.
When you looked right at the light, you could see a little blue tint above the light, but also some yellow and orange. You can learn more about this experiment here.
Watch a Video about the Atmosphere
This is a great video that we watched about the different layers of the atmosphere. It is truly amazing how complex the atmosphere is.
To end our lessons, I gave praise to God for making the sky and providing everything that we need to breathe and stay safe. I prayed for God to help us understand and remember the science behind His amazing creation so we can glorify Him.
