New Preschool STEAM Activity: Liquid or Solid?

Liquid or Solid?

Let your child play with the slime, and put it into the containers and see if it becomes the shape of the container.
This helps your child learn...
· Science Skills (non-Newtonian fluids)

*To do the preschool activity, simply ask for the activity at the Early Learning Center desk. When you have completed the activity, return it to the desk and you will receive a sticker.

¿Líquido or Sólido?

Deje que su hijo juegue con el limo, y ponlo en los recipientes y observa si toma la forma del  recipiente.
Ésto ayuda a su niño a aprender…
· Habilidades de Ciencia (fluido no Newtoniano)

*Para hacer la actividad preecolar de STEAM, simplemente pide la actividad en en escritorio del Early Learning Center (Centro de Aprendizaje Temprano). Cuando hayas completado la actividad, devuelve la actividad al escritorio y recibirás una calcomanía.

STEAM - Magical Math

STEAM/Magical Math

Ever think of MATH as FUN?  Not many do.  It can be tricky and hard to do, but during STEAM we learned MATH CAN BE MAGICAL.

Try these games at home and see if it truly is magic or math 

Find magic number 9:  
 Use a calculator and answer these questions:
a.      Start with your age
b.      Add the number of your house (1229, 270, etc.)
c.       Add the last four digits of your phone number (2201, 5813, etc.)
d.      Add the number of pets and the number of brothers and sisters you have
e.      Then multiply the result by 18
f.        Add the digits of the answer together.
If the answer still has more than one digit, keep adding the digits together until there is only one.
              The answer is always 9.             

Bet you CAN!  Through a series of games and challenges, we will make MATH FUN.

  Foot Feat:  Bet you CAN tell shoe sizes without looking at feet!

Your forearm and your foot are the same length. Try measuring the length of your forearm (from the crook of your elbow to your wrist) and compare it with the length of your foot. You'll be surprised that they are the same length.

Up against the wall:   
Bet you CAN’T pick up a dollar bill
that’s right in front of you
Have your friend stand against a wall with his heels touching
the wall.  Place the dollar on the floor in front of him.
Ask your friend to lean down and pick the dollar
bill up without bending his knees and without moving
his feet.Your friend can’t do it. He’ll fall over if he
tries too hard!

Here's why you can't get it without falling:
When you stand straight against the wall your center of
gravity is over your feet (base) as it should be.
When you bend forward, you move your center of
gravity forward.  In order to keep your balance, you
must move your feet forward too.This maintains the
base under the center of gravity needed for stability.

  On paper the odds look good…but:  Bet you CAN’T fold a sheet of paper in half more than seven times.

What is the Seven Fold Limit?

It’s commonly accepted that you cannot fold a single sheet of paper in half more than 7 times, no matter what paper finish, size, or basis weight you’re using, for two main reasons:
  • Every time you fold your sheet, you reduce your total surface area by half, so eventually you simply run out of surface area to fold.
  • Every fold also increases the strength of the paper. Think about it this way: when you try to tear a page out of your phonebook (if you still have one), it tears easily. But when you try to rip the entire phonebook in half, it takes a lot more effort. The same principle applies to folded paper.
Paper Folding Limit
If you’re a numbers person, think about the seven fold limit exponentially:
2x = total layers of paper, where x = number of folds
Number of Folds Layers of Paper
1 2
2 4
3 8
4 16
5 32
6 64
7 128
8 256
9 512
10 1024
11 2048
12 4096
128 layers of paper? No wonder it’s hard to fold a single sheet of paper more than seven times.

Fact or Fiction?

So is the seven fold limit real? Yes and no.
The seven fold limit holds true for every sheet of paper the average person could get their hands on. You can increase the number of folds with a larger sheet of paper, but as you fold more, your folds get stronger and it gets harder. Plus, you’d have to massively increase the size of your sheet before you can even think about making just one more fold.
Guess the domino
Use some nifty math to fool your friends into thinking you are psychic by guessing which domino they have in their hand.  This trick is simple, but it works every time!
1.       Give a set of dominoes to a friend.  Ask her to choose a domino at random without letting you know which one she has picked.

2.      Ask her to pick one of the numbers on the domino and then do the following calculations.  She should multiply the number by 5, add 7, multiply by 2, and then add the other number on the domino.

3.      Ask your friend to tell you the answer she arrived at.  Subtract 14 from this and you will be left with a two-digit number, which will correspond to the two numbers on your friend’s domino.

STEAM - Art Science

Art Science

 Ever see art and think, "What in the world is that?"

Edvard Munch (Expressionism)

Pablo Picasso (Cubism)
And then there is the Pop Art and Logos we have come to know and recognize instantly-
This month in STEAM we learned about lots a different artists and their styles and then we got to try out our own ideas  

Mosaic Puzzle Art: 

Rubber Bands Tangrams Art

Balance Bots

Sometimes you just need a buddy to keep your whole life in balance, and this one's a quickie!
And for the aspiring tight-rope walker, this bot is your new role model.  Balancing on fingers, noses, or ledges, this bot knows no balancing bounds.

  2 wood skewers
  1 toothpick
  2 balls of plasticine (any clay will do)
  2 google eyes and glue
This is a wonderful balance toy to make, and then change around, iterate, and learn from!
You can do tons of center of mass experiments with this buddy, or just play! 

Step 1: Insert Sticks and Add Clay!
First, insert the two wood skewers so that they are angled down. 
    (You can play around with the position later to get all sorts of different balancing angles.)

Next, insert the toothpick on the bottom of the cork facing down. Then add balls of clay to either side. For the most part, balls about half the volume of a ping-pong ball work great! Experiment to find the best for you.
We need Balance Bot's center of mass (clay masses) to be below the tip end of the toothpick by at least an inch or two. 

Step 2: Add a Face and Let It Rip!

Every bot can use a little personality. Googly eyes can make it come to life, and a mouth isn't bad either.  It can lay flat on the table, but this bot is made to spin upright. Let it rip!
Great things to change to get different results include:

  • The length of the toothpick (cut it)
  • The angle and length of the skewers (cut them), and re-poke them
  • The size of the clay balls
*I used beads and clay for the weights. The kids loved seeing how many ways they could balance the bot: on the eraser of a pencil, on their ear or nose, on the end of a skewer, on the edge of a sheet of paper.


All objects behave as though their mass (the matter from which they are made) is concentrated at a point called their center of gravity.  A simple spherical object, like a ball, has its center of gravity located at its center.  In a more complex object can be located somewhere else.  In your body, the center of gravity is typically slightly higher than your waist, because more weight is in the top half of your body than in the bottom half.

To create this toy that plays with gravity and equilibrium, we will move a cork’s center of gravity away from its center, causing our “Balancing Buddy” to rock and sway, but remain standing upright.

Here are some other experiments to try also:
