Science Sunday: where we rescue a bat

 

We went to a new park in the area on Friday and as we were leaving I saw something crawling across the road to leave the park.  I had to stop and rescue it.
070
Isn’t he cute, in an unbelievably ugly sort of way?  That’s certainly what my kids kept saying over and over again.
071
We kept guard over him (without touching, I know that much for sure) all the way to the side of the road.  Then we talked about what type of bat he is and where he lives.
075
Austin is home to a colony of Mexican Freetailed bats, it’s even one of the “things to see in Austin.”  I personally like the bridge up in Round Rock better to watch the bats come out, but either way it’s a fun site.

After looking up at the bridge above us (the picture above) to remind ourselves where he probably sleeps, then we talked about what he eats.  MOSQUITOES, lots and lots of them.  That’s what we love bats, they eat bugs.  This is good.  I haven’t figured out what use there are for mosquitoes yet in God’s Creation.  I can figure out uses for most other things I don’t like or find annoying, but haven’t found one yet for those.

We also caught a quick video of the bat crawling so you can see it in action.  I wasn’t aware bats could move so well on the ground, but then I remembered that young bats do that.

Let’s see what others did this week:

Wine Cup Christian Academy did a variation on the volcano experiment I’ve never seen before.  Can you guess what she used?

Lionden Landing created a fun model of the solar system (this isn’t the actual model, I just really loved the illustration).


Switching gears, Almost Unschoolers has a great anatomically correct cookie making experience about ladybugs.


Highhill Homeschool had a lot of fun trying to find the best way to make an electrical circuit.

Come back tomorrow to check out my contribution to Around the World in 12 Dishes!  We’re going to Russia!

Science Sunday: owl pellet

Science Sunday

 

I have to admit, I probably had time to write my post earlier this week, but I decided I NEEDED to sew a dress.  Yes, and I wore it to church today, but it was so cold inside I wore a sweater the entire time, so no one saw my pretty new dress.  WAAAHHHHHHH.

 

Okay, enough pouting.  Now to relieve your wondering about the rat skull, for those who were wondering.

 

I picked 3 of these up at Hobby Lobby a few months ago and have been waiting for just the right time to let them have at it.

 

Now, these are not real owl pellets, nor is it a real skeleton (I discovered after buying them), but the plus side is you don’t have to worry about the kids remembering to wash their hands, and you know for sure it’s a complete skeleton.

dissecting an owl pellet

 

I set them each up with a spot at the table and some bamboo skewers to pull it apart and observe the different parts in it.

 

Very quickly we discovered and decided the skewers were not necessary, because it came apart fairly easily (the gray outer material felt like dryer lint to me).

018

 

Than we spent some time carefully pulling everything off of the bones and talked about why the owl would spit all of this up.

 

And finally we looked at the bones and decided what parts of the animal it was, and what type of animal it was.  The boys and Princess switched.  She really wanted the bird one and they wanted the “rat,” though in reality it was a mole.  I guess a mole is rather like a rat.

 

In theory we could have glued it onto a piece of cardstock and shown off our completed skeleton, but the kids were having way too much fun figuring it all out.  And like I said, Superman carried around that silly skull in his pocket for several days.  He wants to take it to the Nature Center so he can trade it in for another skull…….

 

Boys.

 

By the by, I’m loving that I can get emails now from linky tools whenever someone links up, which means I’ll be visiting everyone’s links sooner!  I love hosting because I see so many great ideas, if you don’t take the time to visit all the links you truly are missing out on some amazing discoveries and ideas.

Science Sunday: Prepare to be grossed out…..

Science Sunday

 

This is the cry I heard as I innocently sat at my computer last week, “Mom!  There’s a dead bird in our back yard and Mac’s chewing on it.”

 

Now, I hadn’t fully woken up yet, and was still blinking at the computer screen.  But, I was galvanized into action, and immediately said, “Put the dog inside, and follow me.”

043

 

Yes, I said that.  I grabbed my camera, and a handful of bamboo skewers because I sure as heck wasn’t going to let them pick up the dead bird or touch it.  But, think of what we could observe!

 

 

048

Equipped with our handy dandy bamboo skewers we proceeded to gently examine the bird.  I tried to treat it with as much respect as possible, so we didn’t really poke it, just used the skewers to move feathers and point to things.

 

 

044

 

First we noticed that his toes pointed different ways.  After much discussion we decided this was to help him grab onto branches and balance better.  It’s rather like how our thumb points a different way from the rest of our fingers.

 

046

 

Then we talked about how the bird was missing feathers, and what could have caused that.  I personally think the bird was old, and just couldn’t survive much longer.  The kids of course blamed various different animals for killing the poor bird.

 

050

 

Then we looked at his other side and noticed his feathers were different colors there and talked about how that is a form of camouflage because someone looking up when he was flying would have a harder time seeing him against the bright sky.

 

We also noticed there was a bit of blood around his eyes.  Which really was quite disturbing.  Then I took away the poor bird and disposed of him properly before any other animals tried to eat him more.  Poor guy.

 

And before I could stop them the kids ran around and collected a rather large number of feathers they found all over our yard.  I gathered those up into a bag that “I’m keeping somewhere special” and sent them in to wash their hands 5 times with soap and hot water.

 

Because yes, it was gross.  And yes, there was a definite oogey factor, but I also knew they were going to be talking about it and wondering about it anyways.  Might as well get a science lesson out of it.

054

 

Afterwards I set them to drawing something they observed about the bird.  They were quite sure they wanted to bring in the feathers to the Nature Center so they could trade those in and get “an animal skull.”  Yeah…….  We’ll see.

 

We did not however get a science lesson from the partially pulverized dead snake we found in the yard.  That went straight into the trash.  I was more weirded out by that one because I had started off thinking it was a discarded skin, only to discover it wasn’t.  EWWWWW!

Oh and, if you only check the linky on Sunday, I highly recommend going back later in the week and seeing the posts added in later on.  There’s always some fun ones added in as the week goes on.

We’ve crossed another state border

But of course we had to stop at the Monroe zoo, which is AWESOME.  If you’re ever in Monroe, LA and you have a few hours to spare stop in and wander around.  It’s the perfect size for little guys, and it has a super neat train and boat ride, which sadly weren’t working when we went there.

The coolest part for the teacher in me was their “Small World” exhibit.  I know that’s not what they called it, but it had great explanations for how different insects make their sounds, and all sorts of other hands on ways to learn about insects.

 

My kids loved the nocturnal animals exhibit because they got to see all of the bats and other night animals.  Batman is currently quite obsessed with bats (which is ironic considering his nickname).

IMG_0992

 

We traveled on for all of an hour and crossed the Mississippi.  Incidentally, I accidentally put the wrong initials in my phone to check the distance and was quite shocked to learn we had 19 hours to go, and then realized it was taking me up to Michigan……

 

I didn’t get my usual picture at the state line, but instead got a picture of us in front of the river.  The kids were suitably impressed by the size of the river.

We stopped in Vicksburg at the Coca-Cola museum there.  Coke was first put in  a bottle by the drug store there, and they helped with a lot of the early advertising campaigns.  Batman, who loves Coke, was quite happy to go through there and pose in front of the Santa coke ads.  And by the way keep an eye out next week for a post about Coca-Cola and Georgia (it was invented in Georgia, so it was one of our Georgia activities).  Batman was very disappointed he did not get to drink a Coke from the Coke Museum.  Poor guy.

Of course the kids favorite thing about Vicksburg is an awesome park that is a block South of the Coke Museum.  I mean look at it.  It’s got a couple of awesome playscapes, wonderful water play area, and there’s a whole art area that I didn’t get a picture of.  Or, as my kids called it “Mommy, that’s the labyrinth.”

 

And now we’re in Jackson, MS and at our hotel for the night we’re about to leave and go to my grandparents house.  I can’t wait to see everyone.

Science Sunday: eggs

Science Sunday

We’re getting closer and closer to finishing up our bird study.  And then it’s a chapter or so on flying reptiles and we’ve finished our study of flying creatures.

009

 

As we read what’s in an egg I realized they weren’t getting it, so I cracked a few eggs open and we looked at it to figure out the different parts of an egg.  Hmmm, that reminds me I need to go look up a graphic of an egg……  Excuse me as I dash off to Homeschool Share.

 

Okay, found almost exactly what I need: here.

 

012

 

Then I pulled teeth to get descriptions of what the egg felt like and what the different parts are for.  Really you’d think I was torturing them with how they were acting.

 

 

 

It’s mainly Superman talking there, with me pulling better descriptions out of them.  But, sometimes to truly learn something (like the parts of an egg) you have to get hands on and gross.

014_thumb3

 

And then you need to cook said science information.  It’s very scientific.  And yes, you do need an oven mitt the size of your arm to cook an egg.

 

 

Then happily devour any evidence.  A little later this afternoon (when they’re done eating lunch/watching Veggietales Easter Carol) we’re going to test their egg holders…….

Science Sunday: Migratory life forms

Science Sunday

Back when I was dating Jeff I gave him a bumper sticker that said, “Caution: Migratory life form with a tropism for bookstores.”

 

Yes, it had way too many big words, but it amused both of us.

 

008I briefly mentioned this one a few weeks ago, but since hadn’t had a chance to post about it, well now I am.

 

We read all about how birds migrate in fall and spring to follow the weather (that is much simplified, but I’m feeling lazy right now).  In the fall many birds will travel South, and go to warmer climates.  Beforehand they have to stock up and eat a lot.  So, we did just that before setting out on our migration.

009

 

When they get there the birds are very hungry, because many of them do not stop to eat along the way.  So, we stopped and ate our lunch.  We had to watch out for any hungry predators who might try to steal our lunch (Mac was hungry too).

 

043

We spent the “winter” at the park, which probably isn’t really South of us, more of West.  They prepared places to sleep, and went about their normal park like activities.

 

Then, we headed back North, after eating one more snack.  It requires a lot of snacks to migrate.

 

041

It also requires sticks to be swords and guns…..

 

Afterwards as we walked back and they were super duper tired, we talked about how hard it is to migrate.  It takes a lot of energy and everyone was tired and wanting to ride in the wagon.  But, to truly get the effect, I wanted them to understand how hard it is and so they walked.

 

Yet another example of how mean a Mom I am.  Truly mean.  I’m told this on a regular basis by my kids when I make them do hard manual labor, like cleaning their rooms.

And, if you want to see how someone else talked about migration head over to Mouse Grows, Mouse Learns, because right as we learned about it Anna was talking all about it too.

Science Sunday: Comparing Bones

Science Sunday

 

Our science book went into flying and migration this past week or so, and of course we had to look at the bones of a bird and compare it.

 

So, when I went grocery shopping I bought a t-bone steak and a whole chicken (though I suppose I could have just bought a chicken drumstick, achieves the same purpose).

 

Then we had a couple of very delicious meals, and I was a happy Ticia getting to eat steak, and confusing the heck out of Jeff when I told him not to throw away the bones.  But, he’s getting used to requests like this, and he just requested I get the experiment done soon.

 

015

The kids happily examined the bones and looked at them.  They declared the chicken bone to be smoother, and the cow bone to be more rough.

 

I directed them to think about which felt heavier, and they noticed the cow bone did.

 

Ah ha!  They played right into my hands, so I got to remind them how our book said birds bones are hollow.  Okay, it says there is a web of interconnecting to keep them lighter, but which is easier to explain.017

Then I got out my carefully concealed chicken leg bone I’d cut in half.  And I apologize for it being blurry, but do you have any idea how hard it is to get a close-up picture of a bone when the kids are wanting to look at it as well?

 

So, the inside of the chicken bone is mostly hollow, there’s a rather dried up bit in the middle, which I’m guess to be the marrow.

016

 

The kids thought this was fascinating and had a lot of fun exploring and playing with the bones.

 

I did have to caution them they couldn’t feed them to Mac.  Which was rather disappointing to them.

 

They were also very disappointed when I said I would not cut the cow bone in half for them to see inside it.  I didn’t feel like explaining this was an already cut cow bone.  I did explain that it was too thick for my knife to cut and there was no way I could cut it.

 

That was suitably impressive.

 

But, to get back to actual science, then we theorized what did this mean, and finally after much talking and leading they realized the hollow bones helped the birds fly.

 

I’m a bit behind in making it around to everyone’s posts.  So, if I haven’t commented on your post yet, I’m catching up, but it’s been a busy few weeks.
