May. 14, 2008 - Weather Study ~ Air Pressure
Posted in Weather Study

 

We’ve moved on to air pressure!

All those layers of atmosphere, pushing down on us, well that’s atmospheric pressure! Pretty cool, huh?! The kids asked why we can’t feel that on our heads. *snicker, snicker*

This was a great time to explain a little further why our ears pop as we drive further up the mountains here in Colorado. The higher you go, the less pressure there is. The air pressure pushing in on your eardrums from the outside drops until it’s less than the pressure pushing out from the inside. The imbalance gives us that funny feeling.

Air pressure is continually changing. We have low pressure ~ lighter warm air; & high pressure ~ heavier cold air. We used the experiment below to show that warm air takes up more space than cold.

We put a balloon over a soda bottle and put it into a pot of water. Here is  the balloon before going into the water.

But as the water is heated, the molecules begin to move faster and faster – just like what happens when air is warmed.

That makes the balloon stretch and blow up.  In the atmosphere, warm air takes up more space than the same amount of cold air—and weighs less.

We also made a barometer, the instrument used to measure air pressure. We've been tracking it over several days now. Very cool!

Yeah I'm figuring out things here and there. It helps that Kayla's in computer class and they are learning about HTML codes, web design, etc. And my friend Diane (a day in the life) helped me figure out the background thingy. So change is good. :-)

What I've started doing (when I have time to play around w/ a template) is to save the original in Notepad and then play around w/ the codes in the template on HSB. Then I can always return it to normal if I mess it up.

Where are you getting all these lessons, and ideas for experiments? How long does it take you to get your lessons together? Sounds so fun, wish I could come visit with you and see you in action.

Sorry about the bunny. We just got one last week for ds8 that's a great idea about reading and narrating how to care for a bunny.

It's neat reading about you guys learning and experimenting with air pressure. That's great stuff!

We're doing well, I've just been busy. I'm working on my MBA online with Baker College in Michigan. It takes up alot of my time. I didn't do so great on my last class, so I have to work harder on this one- accounting. I will post again soon, though. Thanks for reminding me.

We have done these and they are so fun, especially the balloons. It still amazes me how air pressure works. Air is everywhere and you don't really think about it much until you take time to study it. Well done.

Hey Kim, I do my own background mixes. I didn't make the actual background pattern on this set though.

We are making a windsock with the ribbons. : )

Hey there!

Those are two more great hands on weather projects. Great job!

We too, have slowed way down on schooling. It took us quite long to get through our cloud study too. But, as you may have saw on my blog, we are now finally finished. It's neat though that after learning so much, we still notice the clouds almost everyday and talk about them.

Hmmm, what's next for us? Well, that's a good question! lol I think we are all feeling like we're needing an extended break from "planned school". We will be taking a vacation in early June and I may not worry about anything else until after that. We are still doing bits and pieces of whatever the good Lord brings our way, so that's definitely school, but I don't have anything planned. I did want to do an oceans unit before going to the ocean, so I may think again about that, but honestly I'm thinking I need a break from planning and preparing too. AND I'd love to have some time to think up plans in more detail for after our vacation and going into the next school year; so I may use the next few weeks to do that.

You know, since we've taken this rather new emphasis and style in homeschooling I've got a lot to think about. I'll let you know as my thoughts start to come together. I'd love to hear of your plans too!

Blessings in Christ,
Melissa

P.S. I just posted about a neat art project we did today. Art is such fun for us, it's hard to call that school, but it is!

We aren't at this point in science, so we won't do it yet, but these are WONDERFUL experiments! I hope you are adding things like this to Pam's second blog for future reference for those of us who will need it down the road. Or, if they are easy enough to find here, that'll work, too. :')
