In this Teachers TV video, Dr Mark Loughlin, a molecular biologist, looks at some demonstrations which relate to the human body and can provide the wow factor for pupils without the need for expensive equipment. Demonstrations include the digestive system, enerry in food, the circulatory system, reaction time and eye dominance.
This Teachers TV video shows an engaging way of demonstrating how quickly a virus can spread. The demonstration uses a harmless, invisible, fluorescent dye. A dusting of the dye is sprayed on the resources the pupils use which transfers to their hands. Role play is used to add excitement.
In this Teachers TV video, Dr Nigel Collins at Kings Charles 1 School wows his Year 9 class when he uses a pig's entrails to demonstrate the digestive system. This demonstration requires a lot of preparation and good hygiene procedures, and an awareness of the sensitivities and religious issues around exposing animal organs.
This tutorial, from Bristol University’s Let’s Dissect, includes a video of a heart dissection with accompanying narration describing the anatomy. Following this, there are slides which highlight the position, structure and function of the main parts of the heart, including chambers, vessels, valves and heart wall. A diagram of the circulatory system allows students to watch a blood cell as it travels around the double circuit.
This tutorial, from Bristol University’s Let’s Dissect, highlights the structure and function of the kidney and includes a video of a kidney dissection with accompanying narration describing the anatomy.
Curriculum links include the excretory system and homeostasis. The process of kidney dialysis is also explained in a clear animation, together with the key advantages and disadvantages of dialysis and kidney transplant
This tutorial, from Bristol University’s Let’s Dissect, highlights the structure and function of the digestive tract, including the salivary glands, oesophagus, stomach, duodenum, liver, gallbladder, pancreas, small intestine, villi, large intestine and rectum
