What's Inside Your Blood - An Edible Model

This fun edible model of blood and what's inside blood is perfect for elementary, kindergarten, and even preschool kiddos!  And, since it's edible, when you're done learning and talking about blood and its contents, you can eat the model!



Building this model is a fun activity to do with your kiddos while you talk about blood and what's inside it.  I recommend preparing the "plasma" in advance, and then -- as you discuss the different components of blood -- let your children choose different food items to represent each type of cell or other items in the blood.

I made our "plasma" using a pudding mixture.  Since blood travels in blood vessels, I made a "blood vessel" out of a plastic baggie.  Then we talked about the plasma and different parts of blood.  The kids chose different items to represent each component of blood as we went along.

Here is a summary of the parts of blood we used.  You can get even more detailed with older children or only use a few of these with younger children:

What's in blood?

#1: Plasma: 
in the model: pudding
* Plasma is the light yellowish liquid that carries everything else in the blood.
* About 55% of blood is plasma.
* Plasma is a mixture of water, protein, sugar, fat, and salts.
* Plasma transports blood cells, nutrients, waste, antibodies, hormones, proteins, and more.

#2: Red Blood Cells (or erythrocytes):
in the model: raisins
* About 45% of blood is made of red blood cells.
* Red blood cells contain hemoglobin which binds to oxygen and carries it all over the body.
* Red blood cells also carry carbon dioxide back to the lungs.

#3: White Blood Cells (or leukocytes):
in the model: bananas & pineapple
* White blood cells protect the body from infections.  They find and destroy pathogens like bacteria and viruses.
* There are many different types of white blood cells.  Neutrophils are some of the first cells to find an injury or infection.  They can destroy bacteria and viruses while also summoning other cells to help protect the body.  Lyphocytes also attack pathogens, make antibodies, and regulate the immune respondse.

#4: Platelets (or thrombocytes):
in the model: appkes
* Platelets are fragments of cells that help form blood clots and scabs.
* Platelets make a base of cells that other cells can stick to when they need to create a scab.  Fibrin also helps this process.

It is also fun to point out that if you eat too much fat, your plasma turns a white, milky color, but this is reversible as your body cleans the fat our of your blood.  Also, if you have an infection you will have more white blood cells than normal since they will be on duty destroying infectious pathogens.  And finally, kids love to learn that blood is made inside your bones!  Red blood cells need replacing every few months and neutrophils only "live" for a day or two, so your bones (the inside, or bone marrow) are constantly making new blood cells!

I hope you have fun making your own edible model of blood and what's inside your blood!  This would go great with a "My Body" unit or a unit on your immune system!

Building Tens Castles (Preschool/Kindergarten Math)

Building Tens Castles is a fun and easy way to learn and review basic math facts (what adds up to ten/deconstructing ten).  My older preschoolers and kindergartener love building, so this is a perfect fit for playful math. You can also use it as an informal assessment.



Simple Supplies:

* building blocks (we use wooden blocks--affiliate link HERE--but you can really use whatever kind you have handy.

* 4-5 bowls

* table or floor space to spread out and work

* optional: favorite action or doll figurines


Easy How To:

You can set this up for a formal 1-on-1 activity, or just integrate it into your regular play.  I prefer to play.

1- To set it up, place your choice of blocks (between 1 and 10) in each bowl.

2- Explain to your child that Tens Castles can only be built with 10 blocks.  He needs to count the blocks in the bowl, figure out how many more he needs, and build the castle.  You can put out the figurine to wait for its castle to be built!



3- Repeat a couple times with different numbers of blocks!

4- Advanced/older kids can also subtract.  Put between 11 and 20 blocks in a bowl, and let your kiddo figure out how many he needs to take away to build a Tens Castle!




We are joining the Learning With Manipulatives team to bring you a great collection of building block learning ideas!!


Here are more great ideas for learning with different kinds of building blocks:

LEGO Engineering Preschool Challenge 1 (STEM): Cars

This LEGO Engineering STEM Preschool Challenge kept our crew busy for almost an hour!



First they worked on the challenge--making their own creations.  Then they made more variations.  Then they played with their masterpieces!

This challenge incorporates three of the four STEM components (science, engineering, and math) just by building.  You could easily add the last component (technology) by letting them drive their cars down a ramp and timing how long they continue to drive.  You could also let them make videos of their cars with a smart phone or camera.

I've always considered physics and engineering branches of science.  As your children work through this challenge, they are engaging loads of science processing skills, including questioning, observing, hypothesizing, experimenting, analyzing, problem solving, and evaluating.  They are using math skills like measuring, comparing, adding, and subtracting.  And, they are doing it on a level that is precisely adapted to their capabilities because they are leading the construction themselves!  At the same time, they are gaining confidence that they can be successful creators and problem solvers!

You can present this challenge to your children as the morning begins or set it up in a classroom as a science center. Or you could set out the LEGOS and see if they create the challenge themselves!

What is the challenge?

Build a car with LEGOS.

Older children may be ready for a bigger challenge:

Build a car that moves.

Or bigger still, build a car that moves by itself!

Give them the LEGOS  (which, in our case, is a giant LEGO / Mega Bloks combo bin!) and let them get started!






Do your kiddos love LEGOS?  Then check out my {FREE} Penguin LEGO counting mat and spelling/reading activity! Also, be sure to pop back and see our other LEGO preschool challenges coming up!

Ice Cube Igloo STEM Project!

Creating an ice cube igloo is a wonderful STEM project that gives kids practice in science, math, engineering, physics, fine motor skills, and patience! It is loads of fun for groups and/or individuals!


Igloos fit in perfectly with our Arctic theme this month, but you could also build them when you talk about winter, polar regions, or states of matter!

To make your own igloo, you need the following

Simple Supplies:

* ice
* salt
* water
* something to build on (we used a plate)
* blender
* freezer

Easy How To:

1- Make an icy "glue" to hold the ice cubes together by blending up about two cups of ice.  Add just enough water so that the ice is soft and moldable, but not liquid. I "cut" the water in with a fork.  It should hold it's shape (or a snowball shape!) easily when you squeeze it together.  When I was a kid living in Utah, we used to call this "slush," so as we built we talked about our "slushy" mixture!



2- Arrange the ice in your igloo shape around a plate or on another building surface.


3- Fill in the gaps between the ice with slushy!


4- Sprinkle salt on top of the ice cubes to encourage them to melt the tiniest bit.  The melted water will freeze to any ice that touches it.  Add another layer of ice and slushy.  My kids were fascinated by the way the ice cubes stuck together and how the slushy could change its shape as you molded it and then re-freeze.  I should add that we live in Houston, so my kids have had a lot less experience with ice and snow than some!


5- Put it in the freezer to harden.  Then repeat steps 2-5 until your igloo is as tall as you want it.  Check out my video to "watch" ours grow!  (If it doesn't load, you can watch it here.)

Working with the slushy and the ice and designing the igloo takes a lot of experimenting and trial and error.  Often, our kiddo would slap a piece of ice or slushy onto the igloo only to watch it break and fall off.  This is okay!  Let them engineer the perfect igloo!  They will figure out how much pressure is okay and how much is too much, and will love their igloo even more.




6- Use slushy to form the top of the igloo.  Also add slushy to the sides to make it air-tight and stronger!


7- Ta da!  Your igloo is done!  We took about two days to build ours and just did each step in between other lessons and activities, letting it freeze while we were busy.  My kids pointed out that a real igloo built in the arctic would have re-frozen as they were building it.  They were also very impressed with the amount of work it would have taken someone to build a life-size igloo, as our 14-inch tall igloo took quite a bit of care and effort!


You can play with your igloo, show it off, or just store it in the freezer for a while!  We had some arctic animals move in!



Your kids can also experiment with the ice and slushy to make different ice sculptures and creations!  
My son continued to grind snow, make ice, and experiment & play with it for two days after we finished!



I loved how the entire project modeled a real-life solution to a problem (housing in the artic), and gave our kiddos experience with the cold ice and snow while staying in a nice warm environment.  And, of course, we talked about how people living in the arctic now do not usually make igloos.  It was still a fun connection to the past and to an environment different than theirs!
The project also let them experience first-hand states of matter: how water freezes into ice and ice melts into water.  For more experiments with this, check out our Frozen Water Magic Science and Elsa's Ice Castle Science Play!


Would you make an igloo with your kiddos?  I'd love to see it!  Feel free to leave a comment, send me an email, or say 'Hi' on Facebook!

{FREE} Valentines Math Games for Preschool - 4th Grade!

It's Valentine's time!  Today I'm sharing our favorite math games with a {FREE} set of Valentine number cards!!




Our favorite math games are variations on "war," a game I used to play when I was a kid too!

Preschool Version:

Give each player 6-20 cards, depending on their age and attention span.

Each player places "his" deck in front of him upside down.  The game is played in rounds.  In Round 1, every player flips the top card of his deck right side up.  The player with the highest number wins the round and collects everyone else's cards.

Repeat in rounds until all the cards are used up.  Optionally, you can continue to play until one player has all the cards.

When two cards are the same or when the "Instant Battle" card is flipped over, the players "battle" by flipping four cards over, still upside down, and flipping one card of their choice over.  The highest number collects all the cards from the battle and the original two tying cards.

Kindergarten Version:

Divide the deck evenly between all players.

Each player places "his" deck in front of him upside down.  The game is played in rounds.  In Round 1, every player flips the top two cards of his deck right side up.  Each player adds the cards together and announces his score.  The player with the highest score wins the round and collects everyone else's cards.

Repeat in rounds until all the cards are used up.  Optionally, you can continue to play until one player has all the cards.

When two cards are the same or when the "Instant Battle" card is flipped over, the players "battle" by flipping four cards over, still upside down, and flipping two cards of their choice over.  The highest score collects all the cards from the battle and the original two tying cards.

3rd-4th Grade Version:

Each player places "his" deck in front of him upside down.  The game is played in rounds.  In Round 1, every player flips the top two cards of his deck right side up.  Each player multiplies the cards together and announces his score.  The player with the highest score wins the round and collects everyone else's cards.

Repeat in rounds until all the cards are used up.  Optionally, you can continue to play until one player has all the cards.

When two cards are the same or when the "Instant Battle" card is flipped over, the players "battle" by flipping four cards over, still upside down, and flipping two cards of their choice over.  The highest score collects all the cards from the battle and the original two tying cards.


Playing math games is loads of fun, especially when you combine it with seasonal themes like Valentine's Day!  It's a great way to review basic math facts, number recognition, and greater/less than skills!

Outdoors STEM: Build a Bridge

I was apprehensive about this project as it began, but the kids soon convinced me it was worth all of our time and the effort they were giving it.


If I had thought about it at all, I would have realized that it combined some of the subjects I am most passionate about: outdoor play, child-led education, science, problem solving, engineering, and math!  But, I'm afraid the first thing that I thought of when my kids started this project on their own was that there had to be an awful lot of germs in that murky water!

Building a bridge can be done in *so* many ways.  We drove a short distance to a beach near this ditch.  As we played in the sand, the kids were soon distracted by this ditch and they challenged themselves to build a bridge across it.  If you don't have access to a ditch like this, you can create your own "river" to build a bridge across.  It can be an actual tunnel-like hole with water in it or just a line in the dirt!  We also have a rock "river" in our yard with a real bridge going over it that our kids play on.  But, that's not the topic for today!

Today, I'm talking about letting your kids (or even challenging them) to build a real bridge outside.  It uses problem solving, scientific reasoning, and qualitative math to engineer a creation that they can actually use!  STEM activities are beautiful to watch unfold because you can practically see children's minds working as they solve problems:

The bridge project began when my son started taking piling rocks onto the edge of the ditch.  It only took a few minutes before he realized that he could build a bridge all the way across the water using rocks.


They piled up pretty fast.  This is wonderful "heavy work" for kids who have lots of energy or who need a sensory processing release.

He quickly recruited help from his sisters, and they had a very big pile of rocks at the edge of the ditch.


I love how they had to work together to move the"heavy" rocks that had a flatter top.  Projects that require teamwork help children learn ways to collaborate and cooperate.


Finally, the bridge was done!

It had to be crossed immediately!


We even came back a week later and it was still there!



Try building a bridge outdoors and watch all the STEM skills interact as your children use scientific reasoning to problem solve and find a way to cross their own bridges! On a bad-weather day, you can even try an indoor version where you cross blanket or pillow rivers!

Have your kiddos ever built a bridge?  I'd love to hear about it and see picures!
