GEOGRAPHY Ask a class what deforestation means and almost every hand goes up. Ask what afforestation means and the room usually goes quiet. It is one letter different, but the difference between deforestation and afforestation is actually the difference between destroying a forest and creating one from scratch. This topic comes up constantly in GCSE … Read more
GEOGRAPHY Whenever I introduce this topic in class, I ask students a simple question. Can a country have too many people, or too few? Most assume more people is always a problem. The truth is more interesting, and the difference between overpopulation and underpopulation shows that both too many people and too few people can … Read more
GEOGRAPHY Stand at the base of the Himalayas and then stand at the base of the Sierra Nevada in the United States, and you are looking at two completely different stories written in rock. Both are mountains, but they were not built the same way. The difference between fold mountains and block mountains comes down … Read more
SCIENCE Every living thing on Earth is built from cells, but not all cells are built the same way. I ask my classes this every year: is a bacterium built the same way as a cell in your own body? Almost everyone guesses yes. The real answer is no, and the difference between prokaryotic and … Read more
Geography Both floodplains and deltas are found in the lower course of a river, both are formed by deposition, and both are flat, fertile areas of land. It is no surprise that students mix them up. But they are actually quite different landforms that form in different ways and in different locations along the river. … Read more
Geography Picture a river snaking lazily across a flat flood plain, looping back and forth in giant curves. Those curves are meanders, and they are a key landform in GCSE Geography. But over time, something interesting happens to those loops. The river cuts through them, leaves them behind, and they become something completely different. That … Read more
Geography Switch on any news channel and within minutes you will likely hear one of these two words. Politicians debate immigration policy. Journalists report on emigration from conflict zones. Economists analyse the effects of both on wages, housing, and public services. Yet despite how frequently these words appear, a surprising number of people use them … Read more
Geography Pick up any Geography textbook and within the first few pages you will encounter the terms developed and developing countries. They appear in discussions about wealth, health, education, trade, and climate change. Yet most students who can use these terms confidently struggle to explain precisely what makes a country developed or developing, what the … Read more
Geography In 2011, an earthquake struck off the coast of Japan with a magnitude of 9.0. The shaking lasted six minutes and triggered a tsunami that killed nearly 20,000 people. Japan sits on one of the most volcanically and seismically active regions on Earth, and understanding why requires knowing exactly what earthquakes and volcanoes are, … Read more
Geography Look at a world map and you will notice something striking. The eastern coastline of South America and the western coastline of Africa look like they could fit together like puzzle pieces. That observation haunted scientists for centuries before anyone could explain it. The theories of continental drift and plate tectonics emerged decades apart … Read more
