Environmental Science – Water Pollution

Any harmful substance towards water quality and aquatic life is considered a pollutant. They can be diseases, carriers, inorganic chemicals, sediments, radioactive chemicals, heat, or feces. There are multiple ways to measure water quality, especially the water quality index (WQI) that compiles several different measurements. Biological oxygen demand (BOD) is the amount of dissolved oxygen [...]

Bees in Crisis

  Ever since the first bees evolved into existence, they have played a vital role in maintaining a healthy ecosystem. They pollinate several types of plants and flowers, helping them to grow, breed, and eventually produce food. However, recently beekeepers report their industry is on the verge of collapse, and farmers relying on honey bees [...]

Killer Mosquitoes

Mosquitoes have been around in our planet for around 90-100 million years. Not only are they very annoying, but they can also transmit a whole host of dangerous viruses such as dengue, yellow fever, and zika. But now, mosquitoes are on the front lines in the fight against- believe it or not- other mosquitoes. Recently, [...]

Environmental Science – Energy Use

Hey everybody this talk is about energy use. Everything requires energy, and energy exists in multiple forms (read last post). There are two categories of energy: renewable and non-renewable. Renewable energy are replenished by the Earth, and we will not run out of this energy. Examples include biomass. Perpetual energy is a form of renewable [...]

Environmental Science – Basics of Energy

Hey everyone, this talk will be focused on the basics of energy. Energy is the ability that something has to do work. Energy is used all around us and by us. There are several forms of energy: Potential energy is stored energy that is positional. Examples include: Gravitational Energy: the energy of a placeChemical Energy: [...]

Environmental Science – Impact and Worldviews

Hey everybody! Welcome back to our third talk on environmental science. We will be talking about our environmental impact and multiple worldviews that people have on our planet. Environmental impact is the impact that humans have on the environment. Whatever impact we have on this planet, good or bad, is our impact. To measure the [...]

Environmental Science – Population Dynamics

Hello everyone! In the last Environmental Science talk, we began talking about sustainability. In this talk, we are going to be moving on to the topic of population dynamics. Briefly, population dynamics encompass all the changes in specific or multiple populations, and relating the population to its environment. To understand this and dive deeper into [...]

Introduction to Environmental Science – Sustainablity

Welcome to our very first Environmental Science blog in the series on STEM Talks! Throughout this series, we are going to focus on how our planet functions to support life, how we interact with nature, our human impact on nature and incorporate many connections between topics in the science. Environmental Science is defined as the [...]
