A food chain is a single path, which help us to work out who eats whom in a habitat, in order to get the energy and materials required for nutrition. Typically food chains involve around four steps. It is unusual for them to be longer...

In this video we are will look at mitosis, including the names of the key stages: interphase, prophase, metaphase, anaphase, telophase and cytokinesis. Mitosis is the process of cell division that produces identical copies of cells, and...

Mitosis produces identical copies of cells, and is involved in growth, cell repair and asexual reproduction - which is how simple organisms reproduce. When cells divide by mitosis, two new cells form and each cell is identical to one...

I want to investigate how population has changed in these cities…but these numbers are just numbers. They don’t mean anything to me. In this video, we are going to discover how great bar graphs are for providing us with a clear visual,...

In this video, we are going to look at a food chain and the different roles within that. So we will discover exactly what each of these words mean: food web, food chain, trophic level, producer, consumer, herbivore, carnivore, omnivore,...

Learn about how predators are specially adapted to hunt, and how prey are adapted to not get eaten.

Learn the basics about the problems with plastics and biodegradable plastics as part of the recycling topic within environmental chemistry.

As populations have grown, farming practices have become more intensified to maximise crop yields and ensure we can feed the ever growing population. Fertilisers and pesticides are used on crops, and animals may be kept inside in more...

This girl has six fingers on her left hand. She has a condition called polydactyly, which causes extra fingers or toes. Her father and grandmother as well as some of her cousins also have the condition. This should give you a clue about...

All living organisms are made up of cells - they are the basic building blocks of life. There are two important categories of cells: plant cells and animal cells. In this video we look at animal cells in more detail. Animal cells are the...

Sometimes animals and plants cannot get enough oxygen to respire aerobically, such as during intense exercise, but they still need to respire to survive. After all, everything relies on respiration for energy. Luckily there is a back-up...
