First Week of School!

We had so much fun during our first week of school!  Let’s see what we did this week…

✓  Colored in a box

✓  Made necklaces with circles

✓  Transferred red items with tongs

✓  Explored lentils and apples in our sensory bin

✓  Did a science experiment

✓  Learned to recognize our names

✓  Learned the months, days, color red and the shape circle

✓  Counted to 10

✓  Did some basic adding and subtracting

✓  Learned some Spanish

✓  Learned the letter “Aa”

✓  Listened to letter sounds

✓  Jumped

✓  Read books

✓  Played outside

✓  Made alligators

✓  Made paper airplanes and flew them

Whew!  No wonder Ms. Taryn is tired!!!  See you next week 🙂



Science is Exciting!!!


A preschooler’s world is one huge science exploration!  From learning about how to roll a ball to what the wind feels like on your to making fizzy letters!!!  Children are learning constantly about their world.  At Square Roots Preschool, we fill our days with fun science projects all the time.  With this particular experiment, the children learned about cause and effect and combining materials when we reviewed letters by making them bubble and fizz!

Follow these easy instructions:

  • Mix baking soda and water in a bowl.   I do a 3:1 ratio of baking soda to water.  You do not want the mixture too runny or too pasty, you want it almost like an oatmeal texture.  You could add food coloring to your mixture too.  I did not for this particular activity but I have added food coloring or Kool-Aid in the past for color and scent.
  • Pour the mixture into any mold you would like to use.  I used a letter mold (I believe I found them at Hobby Lobby) since we were reviewing our letters for this activity.
  • Put the mold with the mixture in the freezer overnight.  The fact that this is freezing cold when you start your activity is exciting in itself!
  • Pop your mixture out of it’s mold.  I put them on paper plates here or you could use a bowl to catch the liquid…
  • Here is where the liquid comes in!  Pour some vinegar (I use white vinegar) in a bowl and let your child squirt the vinegar on the frozen mixture you took out of the mold.  You can use an eye dropper or I like to use turkey basters for many different reasons…this is a whole post all on it’s own!
  • The reaction of the vinegar mixing with baking soda makes the mixture and in our case, the letters bubble and fizz AND a lot of squeals of delight!!!



For preschoolers, daily life IS discovery!  There are so many ways to foster children’s natural inquisitiveness.  Here, we painted our letter B with baby oil as a new medium and the children discovered with amazement that when they held it to the light that the sun shone through.  They made a Sun Catcher!

Teaching the Concept of Volume

Our class recently did a seemingly magical experiment to teach the concept of volume.

Ms. Taryn presented the students with four containers of water, each container a different size and shape. One container was short and fat, one was tall and thin, one was a pint glass, and one was pinched in the middle, vase-like. The students looked at the containers full of water and predicted which container held the most water, and then the next most…


They were all in agreement and very confident. Then we brought out the measuring cup. Each student had the opportunity to pour a container of water into the measuring cup. What were the results?

Container one had exactly one cup of water in it.

Container two had exactly one cup of water in it.

Container three had exactly one cup of water in it.

Container four had exactly one cup of water in it.

Wait. What? How could that be?

We talked about how even though the containers were different sizes and shapes, they all held the same volume! The students were shocked and amazed, much like a magic show. They learned by seeing for themselves the importance of measuring, how things may not always be as they seem, and the concept of volume.

Learning About Our Senses by Doing

Each day at Square Roots Preschool, we work on a group project that requires the students to work together. Sometimes we focus on phonics, sometimes science, or gardening, or cooking. We recently learned about our five senses through hands-on exploration and observation, which is much more effective for preschool-aged children than simply discussing the concept.

We used a familiar object that would intrigue the students so that they could look at it in a new, detailed way: the marshmallow! By passing around one marshmallow and allowing each child to have a turn to make observations, the students were able to listen to one another and absorb all of the information. We saved the sense of “taste” for last so that each of the students could have their own, fresh specimen. The children made some insightful (and sometimes funny) observations:

SIGHT: “I see bumps,” “looks like a lofty snowball,” “lots of white dots”

SMELL: “smells like good,””smells like nothing,” “smells like gluten-free bread”

TOUCH: “feels soft and silky,” “sticky,” “squishy,” “feels like bread and white chalk,” “powdery”

HEARING: “I hear touching,” “a gerbil scurrying around,” “nothing”

TASTE: “vanilla,” “not spicy,” “good”

By observing, experimenting, and discussing the marshmallows, our preschoolers learned all about their five senses by doing. We asked our parents to reinforce these concepts at home by finding objects to explore and describe.
