Greenhouse Effect



  • Jar with a tight lid
  • rocks, weeds, dirt, and water


This was a great way to demonstrate the climate of the world before the flood. The girls took their jars outside and filled them with dirt, weeds and rocks from outside.

Once they had a decent amount of outside elements in the jar we added water and sealed the lid. We placed the jars outside in the sun and observed them for a week.


Above you see the jars once they were filled and below you see them a week later.


The sun cause the water to condensate and stick to the sides of the jar. The water vapor can’t escape because of the lid. The vapor cloud over the earth was much like this. It created a canopy effect over the earth which prevented water vapor from escaping into the atmosphere. This gives you a good representation of the lust and moist earth that we would of had back then.
