Using the Earth's Resources: Potable Water in...

This episode details the key ingredients in fertilisers: nitrogen, phosphorus, and potassium. It outlines the chemical production of nitrogen-based fertilisers, specifically ammonium nitrate, highlighting its rich nitrogen content due to its dual sources. We explain that phosphat ...  Show more

In this episode, we look at plants and nitrogen.Plants require nitrogen to produce proteins necessary for growth. While the atmosphere is full of nitrogen gas, plants cannot directly utilise this form. Instead, they absorb soluble nitrates from the soil. Crop harvesting depletes ...  Show more

Why would people want to remove salt from water? To solve the world's water problem, that's why. Learn all about the efforts to desalinate H2O in cheaper and more efficient ways.

In this episode, we look at transportation in cells. We will explain how substances move into and out of cells, highlighting three key mechanisms. Diffusion is described as the movement of particles from high to low concentration areas. Osmosis is presented as a specific type of ...  Show more

In this episode, we will discuss ion deficiencies in plants.

Healthy plant development relies on mineral ions extracted from the soil. A lack of these ions, particularly magnesium and nitrates, leads to deficiency disorders.
