Effect of Aeration on Self-Sustaining Aquatic Ecosystems

Kyle G, Anthony Centeno G

Self-Sustaining Aquatic Ecosystems are glass jars used in classroom projects that attempt to keep fish, plants and other living things alive, often for a set amount of time.  We know that fish and other animals need oxygen to survive and their gills take in oxygen from the water.  We want to know if aerating the ecosystems will help the fish and other animals survive for 30 days.   We are comparing aerated ecosystems to non-aerated ecosystems and checking for numbers and variety of aquatic animals.  Results pending.

How Does Erosion Work?

Losfim V, Txong Ntong L

The purpose of this erosion experiment is to see the effects of soil erosion to better understand its impact to the world’s agriculture.  We are comparing rocks and sticks and how well they resist erosion.  We set up an erosion table and tested rocks vs sticks, and measured how much material was eroded away.  Results pending.

Investigating the Microclimate of a Courtyard Garden

Steve Landaverde C, Landen L

We have a small garden in a courtyard in our school and we want to know if its climate is better for gardening than outside in the school grounds.  We compared temperature, humidity, soil tests, sun exposure and rain and or snow accumulation.

Our results will tell us if our courtyard is good for gardening, or if it’s good for certain plants.  Results pending.

The Effect of Shared Feeding Spots on Chicken Pecking Rates

Joe W, Natalie W

Abstract: As more chickens are being raised in urban settings, people are beginning to take interest in these fascinating birds and their behavior.   Chickens are experts at pecking quickly and accurately at their prey.  We wanted to know what factors affect the rate that they peck.  Do they speed up their pecking in the presence of other chickens?  We tested three chickens as solos, duos and a trio to arrive at some answers.  Results pending.

The Feeding Rate of Cellar Spiders

Jonathan R, Tommy Y

Cellar Spiders are common long-legged spiders often found in hanging upside-down in webs in moist basements.  We were interested in finding out how often these spiders catch prey to eat.  We collected three Cellar Spiders and monitored their behavior amongst very small crickets.  Although we are still gathering data, these spiders appear to be able to go for days and weeks without eating.  Results pending.

Where's the Best Place to Put Bird Feeders on our School Grounds?

Deborah H, Amaya W, Iren S

Birds are interesting to study, and we know that bird feeders will attract them, but where are the best areas to put the bird feeders?  Our project is about finding the best place on our school grounds to put the bird feeders so more students can see more birds.  We are making observations of bird numbers around our school grounds.  We will also survey our school grounds for trees and find what areas are easy for students to get to or see.  Results pending.
