STEAM Education Fibonacci Numbers

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.

~ Albert Einstein

Leonardo Pisano Bogollo, aka Fibonacci rediscovered the number pattern that is now generally referred to as the Fibonacci sequence. Fibonacci recognized that certain numbers seem to occur in nature more frequently than chance would allow. The number sequence is also used to calculate the golden mean or golden ratio, known in mathematics by the Greek letter phi.

You can easily calculate the sequence in your classroom or at home by adding the last two numbers to make the next.

Here is the sequence:

0,1,1,2,3,5,8,13,21,34…

The first two numbers in the sequence are added and the sum creates the next number.

0+1=1. 1+1=2 2+1=3 3+2=5

We usually open our Fibonacci math enrichment unit with posting the number sequence on the board as a challenge. We ask the class to find the pattern. Surprisingly enough even the first graders usually figure it out.

One of our favorite activities is to go on a Fibonacci number hunt walk. We take the kids for a walk and try to find natural items that show numbers in the Fibonacci sequence.

Here are some example from our last walk

Bougainvillea
Bougainvillea

The Bougainvillea shows three bright pink leaves.

This California native has 5 petals.

Daisy_January_2008-1

We had to count a lot of petals to find a perfect daisy.

We wrote in our journals and drew some of the flowers after the hike. A great way to introduce kids to the Fibonacci sequence.

 

 

 

Baby Chicks in the Classroom

IMG_5410

The chicks have hatched! After 22 days in the incubator the big day finally came. We had been worried because the incubator was left open on day 14 as the class went on a field trip to the Zoo. The eggs were left in the cold for more than 6 hours! A quick internet search revealed that chicks can survive several hours without incubation. We candled the eggs but there was not much to see on day 14. Since we had two duck eggs we candled those as well and the little ducks were paddling in their eggs!

On day 21 we came in on a Sunday to make sure the chicks were doing fine. Nothing was happening. What in the world could we tell the kids? We sang to the chicks (really) and finally we heard a faint chirping. The next day things started to get going. We first saw a small hole.  The eggs started shaking and rolling. We could also hear them chirping in their eggs pretty loudly, but no chicks yet. It is very tempting to help a chick out of the egg at this point. You can see the beak through the pip. Their struggle seems so real. However helping a chick hatch is usually fatal. It really makes you think about struggle in general. Maybe there is more purpose in it than we realize.

It took an additional 24 hours for all of them to hatch and it took all of our restrained not to intervene and help.  Now they are chirping and running around in their nesting box and our yard. We take them into the school garden and let them peck in the dirt and fluff their feathers in the sun. What a treat for the end of the school year!

If you are interested in incubating your own chicks you can find more information right here.

 

 

Classroom Egg Incubation Project Day 1

It is time to incubate again! Here are our beauties happily situated in the incubator. This year we have five chicken and 2 duck eggs. We weren’t really counting on ducks. They have a different incubation time than chickens. We will see how it all works out in the end.

We use a fully automated incubator. It turns the eggs and keeps the temperature at a constant 37.5 degrees Celsius.  The kids still turn the eggs by hand once a day. The automated turning is an amazing feature. Without it we would have never attempted this project. Letting the kids hand turn the eggs once a day helps keep them involved. Keep your fingers crossed for some healthy chicks and ducklings!

Play With Nature

Play With Nature

How much time do your students spend interacting with nature?  Think about it.  What once was an everyday occurrence for kids is now rare and sometimes even non-existent.  Students used to walk to school, climb trees and even got dirty.  Today children only spend about 1% of their time outdoors. They are usually corralled behind a chain link fence on a  concrete surface.  We allow them to have a jungle gym and a ball but they are completely removed from nature…

Why does nature matter?  Nature allows children to play and interact with the physical laws of the world.  To play with a pillbug means to explore the world of crustaceans.  To observe water and sand is to get experience with erosion and how substance change when they are mixed. Sticks are great for building (and sword fights).  When we give children toys, their function and purpose has been predetermined.  Nature provides an open-ended game, wakes curiosity, and has a generally calming effect on the mind and body.

When children are allowed to experience nature it is often within the context of a park or other area altered by man.  We tell them, ” Don’t touch this, don’t pick the flowers, please don’t pick up the rocks.”  We get upset when they want to interact with their environment in a tactile way.  Children’s brains are still developing and so the elementary grade student has to touch her environment, just as much as a baby has to mouth objects, in order to establish the brain mapping of our three-dimensional world. It is a child’s job to make mud pies, throw rocks, and play with sand and water.

Research has shown that playing with nature is an important contributor of healthy development in children.  The benefits of reconnecting with nature seem endless:

  • Increased concentration
  • Better performance on standardized tests
  • Reduction of ADD and ADHD symptoms
  • greater academic success
  • greater impulse control
  • stronger immune response

What can be done right now in our classrooms and homes to give children experiences with nature that are so vital to their well-being? One way to bring nature into your classroom is to create a nature center.  It could include shells, pinecones, sticks, pebbles , and other interesting things.  Allow children to build with the natures center. They will build little worlds of their own right in your classroom.  The center can be used for many academic activities but sometimes it helps to just use it as an area of play.  Even in our world of high pressure academics, our children sometimes need to be able to do what they were meant to do-play.
