Science: Hot Air Balloons

In the beginning, God created the heavens and the earth. ~ Genesis 1:1

Last week Gabriel learned about air.  Discuss with your child how air is all around us.  You can not see the air.  But you can see it move things.  You can smell the air at times.  You can feel the cold or hot air.  Air is a gift that God made for us to breathe.  God blew air into us when he made us.  Plants help by producing air for us to breath.  It is important that we teach our little ones that they can be good stewards of the air that God blessed us with.  When the air is dirty, we call it polluted.  Cars and factories pollute the air.  Encourage your child to help you think of ways that together you can keep the air clean.  Our ideas were: try to walk when we can, ride your bike when you can, share a car when you can, or take the city bus!  Gabe is very sensitive about this topic now which I find very cute!  Every time we get into the car he asks, "Can we ride our bike instead to help the air?"  I love hearing him recall things that I am teaching him.  Makes it all so worth it.

Experiments to do about Air:

Hot Air Balloons!

Show your child a video or clip about hot air balloons.  I like this one from Youtube.   Explain to your child that the heat from the fire heats the air inside the balloon, which in return causes the balloon to inflate and rise into the air.  Hot air rises and pushes the cold air down.  Now for the experiment...

What You Need:

plastic water bottle {little ones}
balloons
baking soda
vinegar
safety goggles {it's just cute and really good precaution}

How to Execute:You simply put baking soda in the bottle and vinegar in balloon....then place the open end of the balloon onto the water bottle.  The warm gas created causes the balloon to inflate!
