Creation Week: On the Second day

Genesis 1: 6-8  6. And God said, Let there be a firmament in the mist of the waters, and let it divide the waters from the waters.  7. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.  8. And God called the firmament Heaven. And the evening and the morning were the first day.

Water is everywhere!  Oceans, rivers, ponds, and lakes are just the most obvious places we find water.  There is also water under the ground and there is also large amounts of water found in the air.  One of the most obvious places water is found in the air is clouds.  Clouds are made of mostly water and air.  A single cloud may contain one hundred to one thousand tons of water.  ( Just for fun identify the clouds: Cirrus clouds, Cumulus clouds, Stratus Clouds and Fog.)  Just for fun you can look up YouTube videos on cloud formation.

The air surrounding our Earth is called the atmosphere.  Our atmosphere is made up of many gases: 78% Nitrogen, 21% Oxygen, 1% other gases.   God created our atmosphere to sustain life.  The air around us provides life, protection from the sun, and keeps the earth from getting to hot or to cold.

Moving air is called wind.  When air’s molecules heat up they spread out.  When warm air expands it becomes less dense than the cool air which causes the warm air to rise.  As warm air rises cooler, denser air flows into its place.  Air is continually being warmed, and that warm air continually rises.  So cool air is continually taking its place.   This continual movement of air is what causes wind.

 

Here are some fun experiments to try:  1. The rain jar.  Set several jars throughout your yard in different spots.  After your first rain, measure the rain water right away.  You need to measure the rain water everyday and record your findings so you can tell how much water evaporated back into the air.  We do this during the Spring and Summer months.  This is a fun way of studying the water cycle.    2.  Make your own wind.  Find how many wind sources you can find in your home.  3. Make your own wind mill out of construction paper.

If you have any ideas you would like to share please share them in the comment section.
