Simulating the Effects of Water Pollution on Daphnia Magna

By: Joselyn G.Year: 2022School: Westminster High SchoolGrade: 10Science Teacher: Huy Pham The goal of the project is to determine at what concentration will Daphnia Magna (aquatic invertebrates) react to water pollution, specifically ammonium nitrate. We raised the daphnia in clear containers until they were able to reproduce. The negative control group was the optimal habitat

How Can We Clean Nitrogen Contaminated Water Organically and Sustainably?

By: Ethan L.Year: 2022School: Westminster High SchoolGrade: 11Science Teacher: Huy Pham There are a lot of farms that contain things like manure and fertilizer which contain a lot of water. The nitrogen rich runoff runs into nearby rivers. This is significant because these ultimately cause dead zones, or kill a lot of the biodiversity. The

The Effect of Carbon Dioxide on Plant Growth

By: Vy N.Year: 2022School: Warner MiddleGrade: 8Science Teacher: Travis Garwick How does carbon dioxide affect the growth of different types of plants? To test this question, Vy grew plants, which were neon pothos, giant white inch plants, and succulents. Vy built her prototype which needed to trap the plants and CO2 in a box, with

Combined Effects of Ocean Acidification and Malathion Insecticide Exposure on Oyster Shells

By: Ashley N.Year: 2022School: Westminster HighGrade: 11Science Teacher: Huy Pham Estuaries are one of the most productive natural ecosystems, providing habitats and food resources for many marine organisms. However, the rise of runoff nutrients such as nitrogen and phosphorus has been accompanied by increased ocean acidification, contributing to the problem of shellfish mortality and ecosystem

Assessing Grass Water Use Efficiency Through Smartphone Imaging and ImageJ Analysis

By: Aniyah S.Year: 2021School: University HighGrade: 10Science Teacher: Shannon Bunch Overwatering and underwatering are widespread issues with extensive consequences. Current approaches to assess water use efficiency (WUE) are inaccessible or indirect. Hypothesis: Smartphone imaging combined with ImageJ analysis is an effective method to determine ideal watering ranges and assess grass WUE. Aniyah examined how nine

Activated Carbon in Water Filtration

By: Stephanie Ph.Year: 2020School: Talbert (Samuel E.) Middle School, 8th gradeDivision: Junior The purpose of my experiment is to test out which plant fiber material would work best for making activated charcoal. For my experiment, I will be testing different types of plant fibers to make charcoal, which will then be made into activated carbon.

The Recycled Bottle House

By: Kelsey C.Year: 2020School: Talbert Middle School, 8th gradeDivision: Junior In this project, I will be building and testing a homemade water bottle house.This is a very important topic because plastic takes a very long time to decompose, and it is not getting recycled enough. This house will be an easy way to reuse bottles

Water Out of Thin Air

By: Audrey Sh. Kara N. & Evan M.Year: 2000School: Portola Springs Elementary School, 6th gradeDivision: JuniorAdvisor: Shannon Hayes The purpose of our fog catcher is to convert fog into clean drinking water. We built fog catchers and tested 3 different fog collecting materials to see which one produced the most water. Fog catchers can be
