This film is from the series Biology Bites available on BBC Teach. Science presenter, Jon Chase, investigates the effects of temperature, water and oxygen on seed germination. He finds out that seeds germinate best in warm, moist and well-oxygenated conditions. He also looks at the effect fertiliser has on the rate of germination and plant growth. Teacher Notes Students could repeat the experiment seen in this short film using cress seeds. Do the students’ results reflect Jon Chase’s findings? Are temperature, water and oxygen the key factors? The scientist interviewed says that water is the most important factor of the three. The scientist also says that fertilisers (nitrates) speed up germination (as well as plant growth). Does this match your students’ findings? Students could then look at the fertilisation of plants, by placing pollen onto a stigma and observing it grow into a pollen tube.

This film is from the series Gastro Lab available on BBC Teach. Paralympic athlete, Jordanne Whiley, explains why carbohydrates are important in her diet. Meanwhile, Stefan Gates uses a ‘sugar shotgun’ to illustrate how energy is released from food and creates heat. We hear about the difference between complex and simple carbohydrates, their food sources, their function in the body and the energy they release. We are advised to get 55% of our calories from carbohydrate rich foods, particularly complex carbohydrates such as wholegrains, wholemeal bread, rice and potatoes. The links between simple carbohydrates, or sugar, and the risk of tooth decay, heart disease and weight gain are explained. The idea of balancing energy in and energy out is highlighted. Teacher Notes You could ask your students to compare the amount of calories per 100g or per portion found in a selection of carbohydrate-based foods, by examining food labels or using nutritional analysis. These foods could be placed in rank order and evaluated as to which would be the best to eat before a marathon.

This assembly framework is part of a series of School Radio assemblies, which can be found on the BBC Teach website. On 1 December 1955 Rosa Parks refused to give up her seat on a bus to a white passenger, contravening local laws. Parks’ actions made her a figurehead of the Civil Rights movement and an inspiration to those fighting for justice and equality. The purpose of BBC’s content is to inform, educate and entertain.
