Today the 5th grade investigated topics of interest.
Here are some of the explorations that took place:
* Identifying and classifying rocks and minerals
* Researching elements and putting together the 1000 piece periodic table puzzle
* Observing and learning about the monarch, viceroy and swallowtail butterflies
* Understanding what makes food "organic" and if organic food or locally grown food is better for the environment
* Researching climates of the world
* Making sense of the physics equation for acceleration
* Researching penguins and pandas
* Learning about holograms
Congrats to all the students who participated in HCES Pigeon Watch. All of the presentations we have seen so far have been amazing. So far, the most elusive pigeons in NYC seem to be the REDs!
Worms loosen soil and are called, "Nature's Plowers."
Worm poop is called castings. Castings help fruit and veggies grow bigger and better.
Worms are invertebrates.
Worms are annelids.
Worms can eat newspaper.
An adult worm can have 120-150 segments.
Each segment of the worm has small hairs called, setae (see-tee).
Here are some of their observations and wonderings!
4th graders compared the mass, volume, and density of unpopped and popped popcorn.
Adam, Daisy, Simone, Sidney and Isha shared their conclusions.

In the wild, all members of a species usually look similar. Robins, for example, all have gray backs and red-orange breasts. All crows are black. But the pigeons we see around the world are a different story. They show remarkable color variation, just like cats and dogs. Why? They are all descended from the blue-bar Rock Pigeon (see “color morphs” page). For hundreds of years humans bred pigeons just for their colors, homing instincts, or racing abilities. 400 years ago many of these special breeds escaped into the wild and became the ancestors of the pigeon flocks that we see today.
Wild pigeons adapted to life in cities, in parks, on beaches, and on farms, and their populations continued to have individuals of many different colors. Take home challenges are completely optional and we invite anyone to participate. Anyone who completes all of the challenges this year will receive a special science prize. The challenges can be found hanging on the science room door!
