"Liquid density tower"
Grade 7-9
By: Kaylee Prasad
Abstract:
The objective of this experiment was to compare the densities of different liquids to understand why different types of liquids do not mix when stacked on top of each other. Five liquids were poured into a jar and the liquids with a higher weight have a higher density, so they stayed below the liquids with a lower density. The same quantity for each liquid was used in the experiment. The liquids did not mix with each other because of their density which resulted in a tower.
"electrolysis"
Grade 7-9
By: Amory Crandall
Abstract:
This project is about separating water into hydrogen and oxygen. Water will be separated using electrolysis.
"mangrove model"
Grade 7-9
By: K’moya Boyea, Sophnack Duverger, K’mauni Ronan
Abstract:
A model of the mangroves was made to display the order in which the mangroves are found on the land. The model is 3d and contains the Red Mangrove, Black Mangrove, and White Mangrove.
"Water cycle"
Grade 7-9
By: J’sani Rhymer, Azania Glasgow
Abstract:
Water is one of the key ingredients to life on Earth. About 75 percent of our planet is covered by water or ice. The water cycle is the endless process that connects all water bodies. It joins the Earth’s oceans, land, and atmosphere. The Earth’s water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans. The rain came from water vapour that escaped the magma in the Earth’s molten core into the atmosphere. Energy from the sun helped power the water cycle and Earth’s gravity kept water in the atmosphere from leaving the planet. The oceans hold about 97 percent of the water on Earth. About 1.7 percent of Earth’s water is stored in polar ice caps and glaciers. Rivers, lakes, and soil hold approximately 1.7 percent. A tiny fraction, just 0.001 percent exists in the Earth’s atmosphere as water vapour. When molecules of water vapour return to liquid or solid form, they create cloud droplets that can fall back to Earth as rain or snow, a process called condensation. Most precipitation lands in the oceans. Precipitation that falls onto land flows into rivers, streams, and lakes. Some of it seeps into the soil where it is held underground as groundwater. When warmed by the sun, water on the surface of oceans and freshwater bodies evaporates, forming a vapour. Water vapour rises into the atmosphere, where it condenses, forming clouds. It then falls back to the ground as precipitation. Moisture can also enter the atmosphere directly from ice or snow. In a process called sublimation, solid water, such as ice or snow, can transform directly into water vapour without first becoming a liquid.
In its three phases (solid, liquid, and gas), water ties together the major parts of the Earth's climate system: air, clouds, the ocean, lakes, vegetation, snowpack, and glaciers. The water cycle shows the continuous movement of water within the Earth and atmosphere. When it rains and the sun comes out evaporation takes place and then condensation. When it rains, water is released from the clouds and precipitation takes place.
"Water Filtration system"
Grade 7-9
By: Kaliq Jennings, Michael Findlay, Ethan Faulkner
Abstract:
The objective of this project was to filtrate and purify dirty water to clean drinking water by using resources in the environment. We expected that after completing this project, the contaminated water would have been purified and we would be able to drink it. This project is important as it allows a cheaper and more organic alternative to be used which works just as well as a higher-end water filter. A filter funnel was created using a plastic bottle. Fine and coarse sand, charcoal and gravel were layered on top of a piece of cloth (which plugged the mouth of the plastic bottle) to create a filter for the contaminated water. From what was observed, the contaminated water was filtered and turned into almost drinkable water. Completing this project gave us a clearer understanding of the water filtration process and that environmental resources like gravel, sand, charcoal and plastic bottles can be used to purify water.
"durability for batteries"
Grade 7-9
By: Karissa Scatliffe, Miriam Bempong, Jason Dunkley
Abstract:
The objective of this project is to test the durability of different brands of batteries (Duracell, AcDelco and Kodak). We believe that the Duracell battery will last the longest because we see it being advertised more and it has 29% of the market share in sales. The hypothesis was tested by inserting a pair of batteries of each particular brand into three different flashlights. Each flashlight was powered on all at once and the time was noted. The flashlights were monitored until each light completely faded. From our observation, the hypothesis was inaccurate because AcDelco, and Kodak lasted much longer. The Duracell battery lasted 2 hr 50 mins. The Kodak Battery with an expiration of (2018) lasted 7 hrs and the AcDelco with an expiration date of (2020) lasted 13 hrs. In conclusion, we have learned that ‘we can’t judge a battery by its cover’ because Kodak and AcDelco were founded to be more durable than Duracell batteries.
"solar irrigation"
Grade 7-9
By: Eylin Santana
Abstract:
Solar Irrigation is a solar-powered irrigation system that is environmentally and budget-friendly. The lack of water during a drought is a major problem, especially for small farmers. A solar irrigation system solves this problem by using the sun’s energy to charge batteries which could power a water pump to get water to a farm. This project will be turned into a model of a solar irrigation system that can actually work in real life.
"growing crystals"
Grade 7-9
By: Kande Richardson, Rashuana Dixon, A’nyah Thomas
Abstract:
A crystal is a solid substance in which the atoms are arranged in a repeating pattern that is highly organized. For this project, we will be making crystals using everyday items such as Epsom salt, Borax, Table Salt, and Sugar. Once all the processes are complete, the best crystal will be judged by which substance grows them best.
"water energy"
Grade 7-9
By: Caleb Stoutt
Abstract:
This project is displaying a working model showing how wave energy works and how it can power a country. Wave energy is a renewable energy source taken from the waves as they move across the water. Wave energy doesn't require land unlike wind and solar energy. Every day we use electricity and for a cleaner and greener earth, this is an excellent choice.
"Fossils"
Grade 7-9
By: Kenique Jones
Abstract:
Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes, and rivers. Fossils also include any preserved trace of life that is typically more than 10, 000 years old. There are two main types: body fossils represent all or part of the organism's body and trace fossils show evidence of the organism's behaviour.
"dna model"
Grade 7-9
By: Abigail Smith
Abstract:
The abbreviation DNA stands for Deoxyribonucleic Acid. It contains the genetic information responsible for the development and function of an organism. The purpose of this life sized model is to demonstrate how the DNA model works. DNA is full of information about your genetic makeup. It explains why certain things about you look the way they do and function the way they do. It can also provide information about your health. Through DNA, genes are passed on from generation to generation.
"rainbow fire"
Grade 7-9
By: Tyasia Cameron
Abstract:
My project is on Rainbow fire, this experiment demonstrates the changes in the colour of fire when metals or metallic salts meet the flame. These chemicals which are metal compounds burn when exposed to flame. The burning of the compounds is what produces the colour changes to the flame.
"making plants move with light"
Grade 7-9
By: Shamoy Joseph, Jaime Molyneaux, Zevieh Abraham
Abstract:
Our project will be an experiment on how light manipulates a plant's direction of growth. In the experiment, a plant was grown and observed for one month. During that month the plant’s direction of growth was monitored. Then, after the month was over the direction of the plant was documented on a table in seven-day intervals.
"traffic light experiment"
Grade 10-12
By: Auri-Ana El Shabazz, Nikeideon Melville
Abstract:
In this experiment, the redox reactants undergo several colour changes, hence, the name traffic light experiment. For example, when indigo carmine is mixed with oxygen, it turns green. Chemical reactions known as redox reactions occur when the oxidation state of a substrate shift. Redox reactions have two classes: electronic transfer and atomic transfer. In this experiment, the chemical components undergo electronic transfer. An electron transfer is the movement of electrons from one location to another.
"invisible fire extinguisher"
Grade 10-12
By: Jeremiah Penn, K’mori Walters
Abstract:
The experiment is about putting out fires by using a homemade fire extinguisher. The way the homemade fire extinguisher works is by putting baking soda and vinegar into a beaker and covering it, until there is enough carbon dioxide inside to put out a fire. The reason why we are doing this project is because we would like to show others how they can put out fires by cutting off oxygen or how fire extinguishers are made.
"all in one organic agriculture"
Grade 10-12
By: Tanesha Hushman, Amanda Penn
Abstract:
A farming system that is attached to a supermarket and is the same company/ operates as one in a vicinity. People go to the supermarket and see, first hand, the organic and fresh agricultural foods being produced and exported to the supermarket; therefore causing more customers that all want the healthiest and freshest produce.
This farming-system supermarket aims to provide fresh, locally grown food for the community. Having a supermarket where all your farming foods are organic and healthy and fresh is the best way to go. Produce is carried straight from the farm to the processing building and then finally to the supermarket. Exporting ports are found on the compound which allows products to be exported to other supermarkets and stores. All produce and items are organic and none are made artificially. This benefits the health of the customers and it is super easy to start and maintain a healthy diet and lifestyle.
"tooth decay"
Grade 10-12
By: Davida Chinnery, Xarion King, DeJanea Maduro
Abstract:
It was critical that we made decisions regarding our nutrition that were beneficial to our health. It was very important for us to have been aware of the effects that the various beverages that we consumed on a regular basis had on our dental enamel over the long term. Over time, consumption of an excessive amount of sugar was detrimental to our oral health. Consumed beverages with a high sugar content had been linked to a number of health problems, including tooth decay, gum disease, and a variety of other dental difficulties. In this experiment, we replicated the effects that sugar caused on the enamel using eggs. The experiment illustrated how prolonged exposure to sugary beverages might have an effect on dental enamel.
"carbon sugar snake"
Grade 10-12
By: Amani Brown, Denae Scatliffe
Abstract:
In this presentation, we will conduct the carbon sugar snake experiment and discuss the results. The Carbon sugar snake is an experiment that demonstrates the concept of combustion. This carbon snake is made by burning a mixture of sugar and baking soda. This reaction happens when sugar combusts (burns) in the presence of oxygen producing carbon dioxide gas and water vapour (also a gas), which pushesmore of the sugar/baking soda mixture upwards. Some of this additional sugar heats up but doesn’t have access to any oxygen, so instead of burning, it undergoes thermal decomposition, producing solid carbon and more water vapour that now gives the snake some shape, and also gives the snake its black colour.
"mosquito trapping technology"
Grade 10-12
By: Jaiden Isaacs, Xhayne Pemberton, Anthony Innis
Abstract:
There have been periods of rise and fall of diseases by mosquitoes such as dengue caused by Aedes aegypti. The aim of this project is to trap mosquitoes in three selected urban locations in Tortola with and without lures [scents] to get a rough estimate of population size. The specialized mosquito traps have been loaned to us by the researchers at Green VI. At the end of this comparison of mosquito counts with and without lures, the data will be forwarded to Green VI for the sex, and species of mosquitoes to be analysed. Further actions can be taken by this organisation as they have a data-driven- vector biological control programme for this particular species of mosquito.
"solar oven/cooker"
Grade 10-12
By: Jada Peters, Christopher Peters, Marvin Thomas
Abstract:
This is the use of a simple technology that has already been developed to harness the sun’s energy to warm food. The oven is all made of cardboard with the cutout cover of the box, covered with aluminum foil as the solar panel. The principle of operation is that the light from the sun is reflected off the aluminum onto the black paper which lines inside the box, absorbing the heat by radiation.
The cover of the box will be adjusted at different angles to reflect the sunlight into the interior of the box which contains a small beaker of water. The temperature of the water will be measured every half hour for three hours. The experimenters will pay careful attention to variables to ensure validity and reliability.
"solar oven"
Grade 10-12
By: Jayden Glasgow
Abstract:
This project was designed to allow us to utilise natural resources in a creative yet efficient manner. Using items that are easily accessible, one is able to create a functional household necessity, an oven. Using sunlight to generate heat, one would be able to either warm up or cook something in this self-contained space that is designed to reflect and refract light and contain heat.
"water powered generator"
Grade 10-12
By: A'Zaria Martin
Abstract:
My project is about a water powered generator. It is about using a safe, sustainable substance (water), instead of gas, a substance that is now expensive because gas production was low. Hydropower is a large source of clean renewable energy being used nowadays. Hydroelectricity has zero pollution so it is also better for the environment and makes it safe to be anywhere.
"improving water retention in soils"
Grade 10-12
By: Makeda Gumbs, Shinique Robin, Chikae Stoutt-Igwe
Abstract:
This experiment will investigate the soil amendments that will improve water retention as sandy soils which are common in the BVI are not very fertile because they drain water too quickly. We will add different materials to the soil samples to see which works best at water retention.
