All About Birds

As we’ve been having our little bird theme, I’ve seen M’s love and understanding of nature blossom.  He has been spending every spare second outside… enjoying being a kid.  He’s gotten more baths in the past 3 weeks than he has in his entire life.  Ok, that’s an exaggeration, but that’s pretty much how it has seemed to me. :)

The first thing he does each morning is look out his window to see if any bunnies or squirrels or maybe even deer are having breakfast:blog pictures 035and he can recognize the songs of cardinals, robins, blue jays, chipping sparrows, and chickadees.  He even does a good imitation of them!  He’s picked up the names of many flowers and trees just by… osmosis I guess?  Sometimes I just don’t know how he knows so much!

So – on to our bird activities…

Math Skills:

I found a cute little game here.  The birds are made by taping pennies onto the playing pieces, and there are 3 dice to choose from – easy, medium, and difficult.  We used the medium one which made us go back one space and/or lose a turn once in a while.  The first birdie to hop along all the clouds and make his way to the tree wins. :)blog pictures 022

Visual Discrimination:

I put out this bird matching game from Homeschool Share (it’s supposed to be a file folder game, but I just made it into mats).  M loves this and was very interested since he hadn’t seen it in a while.blog pictures 052
Here’s a better picture; you match up cards with enlarged details to the correct bird:blog pictures 055

Language Skills:

I made a set of bird picture cards of birds we have near our home.  I printed two sets, then cut the name off of one set.  We used these like Montessori 3-part cards.  blog pictures 056
M matched up the pictures first, then found the correct name for each bird too.  This was the first time we’ve tried something like this and it went really well.  Some were easier than others, like Mallard Duck and Canada Goose since they have two words in their names.  He usually looked for the first letter, then decided if the rest of the word looked correct.  I divided these up into smaller groups for him (there are 25 in all which would’ve been a bit overwhelming).blog pictures 021 I made an online list of these birds at enature.com so we could listen to their songs and sounds.  You can read more about the cards, as well as find the link for the enature list in this post.  M really enjoyed listening to the birds on the computer!


Science:

We looked through some old encyclopedias – old, as in I had them as a child and have kept them for some reason.  M was fascinated with all the exotic birds pictured. blog pictures 041
We also looked at some egg pictures and I pointed out the ones for “our” birds:blog pictures 040
The encyclopedia also did a great job of covering the various types of beaks and feet that birds have.   blog pictures 042
We made these pipecleaner bird feet…blog pictures 051 the one on the left has three toes in front and one in back.  Songbirds curl their toes around branches (M did this on his finger, and really liked it), and even sleep this way!  Birds of prey (eagles, hawks, owls) also have three toes in front and one in back like this, but they have very, very sharp claws on them (the better to catch mice with – yum!).   The foot on the right is like a woodpecker’s foot – two toes in front and two in back.  They use their toes to dig into a tree’s wood as they climb.

We also took a look at some information I found at the Fernbank Science Center website.  We learned more about bird feet and beaks and did the activity sheets pictured below…

Match the foot to the correct type of bird:image
And match the beak to the type of food it’s meant for:image
I was searching for ideas to make this a more hands-on learning experience for M, and the next time we do a bird theme, I will definitely use two great activities from The Adventures of Bear.  First, a great hands-on beak activity here, and a bird diagram puzzle here.

Other Bird Activities:

M cut yarn into small lengths (about 4") and we put it out on our doorstep for the birds to use in their nests:ts 300 (1)
Last summer he planted some gourds, specifically meant for wren houses.  Daddy drilled a hole in one, cleaned it out, and hung it up to dry all winter.  This spring M painted and glazed it and we hung it in a tree.  It looks like a cozy home, and we are waiting for you to move in, little wrens!  blog pictures 006
We did some super-fun bird crafts; click on the photos below to go to the post about each one…

We learned some new songs too!

And we finished it all up with a science experiment about air pressure.

Science Experiment – Battery Power

blog pictures 007M is obsessed with batteries and electricity lately.  I don’t know how many times he has come to me, screwdriver in hand, to see which kind of battery and how many of them a particular toy takes.  He is always trying to figure out how things “go”.

So you can imagine his excitement when I told him our experiment for the day would be trying to light a flashlight bulb with a battery and aluminum foil.

We had a little discussion about how metal is a conductor (his newest word now) of the energy stored inside a battery.  Wires can take this energy to working parts, as can almost any metal, even aluminum foil.

Interestingly, he asked me, “how do wires send the electricity?  There are no holes in wires!”.  It’s so neat to see his little brain working… the idea of electricity traveling inside a wire – well, it would have to have a hole to get into it, right?  So I explained that the whole wire – even the outside – is a conductor, and the energy runs along it.  He asks some tough questions sometimes and I’m not sure my answer entirely satisfied him.  Ah well, he has time to learn!

To do this experiment, take the small bulb out of a flashlight.  You want something like a 2 watt bulb, maybe 3 watts at the most.  You also need scotch tape, a D battery, and two lengths of aluminum foil rolled up tightly.  Ours were about 12” long I’m guessing.

Use the tape to attach one end of each foil “wire” to the battery.  One will be attached to the negative side:blog pictures 014 and one to the positive side:blog pictures 015

Next, take the opposite end of one of the foil “wires” and wrap it around the base of the bulb.blog pictures 016Get it as tight as you can, and use tape to secure it if you need to.  This was the toughest part for us… those tiny bulbs are a bit hard to manage.

Next touch the very bottom of the bulb with the loose end of the other “wire”.  Your bulb should light up!  M loved doing this part!blog pictures 002Energy from the battery circles through the foil and lights up the bulb.

No pictures of this, but we also used one length of foil and a AA battery.  We placed one end of the foil at one end of the battery and the other end of the foil at the other end of the battery.  Then we placed our fingers over the foil at the ends of the battery and could feel it get warm, then hot!  The energy in side the battery was going through the foil and making it and the battery very warm.   (Note… you don’t want to do this with much bigger batteries, at least with small children, because at some point it could burn.  These batteries are not going to electrocute anyone, but it’s always best to be safe!)  I wonder if this would be a good way to test batteries and see if they are still good?!

Have a beautiful and energy-full day! :)

Bird Craft #1

One of our little bird-themed activities was this shapes bird craft.  I cut out a few shapes (large oval, circle, heart, triangle, 2 tiny rectangles), and had them waiting on the table for M one morning.  blog pictures 031I quickly drew a picture for him to use as a guide, and added some foam stickers, a googley eye, and some decorating options (watercolor pencils, watercolor paints, glitter glue).


You know once he saw the glitter glue he was all over this, right?  :)  Mmmm… sparkly…

As he put his little bird together I guided him by naming a shape for him to pick out, asking him where that shape was on the picture I had drawn, and then talking about that particular part of the bird.  This was a more mama-led activity than most of our crafts, but I wanted a little shape reviewing, and I used it to talk about the parts of a bird.  They have wings, not arms; a beak or bill instead of a nose and mouth; feathers  instead of bare skin or fur, etc.  I was sneaking in a little biology. ;)
blog pictures 003
After he glued everything in place the decorating began!  Of course he went straight for the glitter glue first, then used a couple of the watercolor pencils (although he did not actually paint over them with water), then used q-tips in the watercolor paints to fill in some areas.  blog pictures 030
I just love how this little birdie turned out. :)  M named him “Easter Bird”.   He sure is a colorful one!

I made a template of the shapes we used, although it would be simple to do without them.  If you are interested you can download it here.

It would be neat to use feathers to decorate this little bird, but I. can. not. stand. feathers.  Uggh, the mess they make!  M can use feathers at Grandma’s house, hee hee.

Have a beautiful day! :)

Science Experiment – Shiny Pennies

This was a quick and fun experiment, with speedy results… which is what you want with a 3 year old boy whose name begins with M.  Although I’ve seen this experiment around, I actually decided to do it after seeing it in Play and Find Out About Science, by Janice VanCleave.

We found a handful of old, darkened pennies:blog pictures 030 (Eek!  Don’t look at my stained bowls throughout this post, please!)

M mixed 1/4 tsp of salt into 1/2 cup of white vinegar:blog pictures 058

Then we placed the dirtiest of the dirty pennies in the solution.  M spilled vinegar in the process and by the time I had it cleaned up and was ready to snap a photo of the bowl, they looked like this:blog pictures 031 It was about 2 minutes and they were already getting super-shiny!  We did this part over and over with all our pennies, and talked about how copper is a metal and oxidizes when it’s out in the air.  So now my 3 year old is walking around saying “oxidized”. :)  He has future nerd written all over him. 

Later we found a shiny paperclip and more dirty pennies.  We mixed up another salt and vinegar solution and placed the paperclip and pennies in it together:blog pictures 059 Then we waited.  A couple of hours later we checked and here’s what our silver paperclip looked like: blog pictures 067 The metal on the paperclip attracted the copper particles that the pennies shed in the vinegar. 

I’m not sure M took a whole lot of knowledge away from this experiment, but he really enjoyed it and had fun!

Birds – Picture Cards and Songs

clip_image002
We are so blessed to live where we do… with almost a full acre’s worth of yard and an abundance of trees, we have many different little feathered friends. :) The pretty one above is one of my favorites (that’s a public domain photo, not actually one of our goldfinches, but ours are just as sweet-looking).  Additionally, we have a handful of trails near a creek bed in a wooded area to our north, and a small lake to our south.  We see plenty of wildlife, including some amazing birds.  The lake often has bald eagles near it and we even saw one on a tall pine in our backyard a couple of years ago!  This is all despite being pretty near a major highway, the one drawback to our neighborhood.

Now that spring has sprung the birds are out in full force and we’ve been learning a lot about these little guys.  I couldn’t believe when I sat down to make a list of all the different species that I came up with 25!  I’ve learned all their names over the past 10 or so years thanks to my nature-loving husband.  And it’s so neat and fun to share this knowledge with M.

Another post about all our little bird-study activities will be coming soon (I hope!), but for now I wanted to share with you some little cards I’ve made.  These are the 25 species of birds we’ve encountered in our own yard or within a mile of our home.  I’m sure there are others, but really 25 is enough, don’t you think?  These could be used as Montessori 3-part cards if you made two copies of each.  They’d also be great for a matching game or “go fish” type card game.  We are using them simply to learn their names and talk about them.   And as long as I have them made, I might as well share them, right? :)  Click on the picture to go to the download page:image

One of our favorite activities has been learning the various bird songs.  I’ve made a list at enature.com of all 25 species… we use the list to learn more about each bird and most have an audio file to listen to the sounds and songs of each bird.  I’ve found it fascinating and M seems to really enjoy it too!  The link is here, and you’ll need to use BirdCards9 as the user name and blogger as the password. Along the top of the page (about an inch down from the top) you'll see a menu bar; under "Local Nature" click on "Personal Wildlife List" to go to the list I created.  Any questions or problems, contact me!  You'll need to click on the birds and then you'll see a yellow button labeled "listen".  Click on this to hear each bird!

If you use these and blog about them, please include a link back here.
Have a beautiful day! :)
