Video clip - Muriel Wheldale and complex gene interactions
This video clip from the BBC (from the TV series Botany: A Blooming History) looks at how geneticists in the early 20th century investigated the puzzle of the inheritance of characteristics. This can be used to introduce more complex patterns of inheritance to more confident students. These can include ideas of co-dominance, epistasis etc.

Video clip - William Bateson and patterns of inheritance
This video clip from the BBC (from the TV series Botany: A Blooming History) continues the story of the pioneers of genetic research, showing how William Bateson used logic and patience to explain patterns of inheritance, and the ideas of dominant and recessive genes. Students can then be given experimental data to interpret and develop the skills of showing simple inheritance patterns using punnet squares.

Video clip - The binomial system of classification
This video clip from the BBC (from the TV series Botany: A Blooming History) introduces the binomial system of classification, through the story of pioneering scientist Carl Linnaeus. Use as a starter for a lesson on the different levels of naming and classification of living organisms.

Video clip - Plant adaptations to overcome environmental limitations
This video clip from the BBC (from the TV series Botany: A Blooming History) introduces the idea of limiting factors in photosynthesis, and the way in which plants are adapted to their environments. Students can watch the clip and pick out the factors which would limit the rate of photosynthesis. This can then lead to experimental work.

Video clip - Genetic engineering to increase productivity in rice
This video clip from the BBC (from the TV series Botany: A Blooming History) discusses the importance of genetic engineering for feeding a growing population, introducing a group of research scientists working on rice. It can be used in the context of global warming and the ecology of LEDCs. It can also be used to discuss limiting factors and photosynthesis.

Video clip - Linnaeus and the first system of classification of plants
This video clip from the BBC (from the TV series Botany: A Blooming History) introduces the ideas underpinning classification, through the work of Carl Linnaeus. The emphasis is upon using observations in order to group organisms. It can be replicated in the classroom using flowers, shells, leaves etc.as an introduction to the making and using of keys.

Using Cress in the Lab
Cress seeds are cheap and easy to grow, and offer a useful way to look at the germination process.
|
Using Onions in the Lab
Onions are easy and cheap to source, and make a great resource for looking at cell structure, particularly stomata, and for extracting DNA.
|
Using Venus' Fly Trap in the Lab
One of the SAPS Star Plants, Darwin called the Venus' Fly Trap 'one of the most wonderful plants in the world'. Great for teaching about adaptation and interdependence.
|
Using Garlic in the Lab
Garlic can provide a useful and easy-to-source resource for the biology lab, for looking at topics including mitosis and the cell cycle.
|
Using Broad Beans in the Lab
Broad beans are quick and reliable to germinate in the lab, and an excellent example for topics including nutrient cycles, nitrogen fixation and mutualism.
|
Using Elodea in the Lab
This pondweed is widely recommended for photosynthesis experiments, as it can be used for demonstrating oxygen formation during photosynthesis. It is easily available from aquarium shops and science suppliers.
|
|
Using Green Algae in the Lab
These algae make a great resource for demonstrating photosynthesis, particularly with the 'algal balls' activity.

Using Pelargoniums (Geraniums) in the Lab
Geraniums are often found in the school lab, but they're rarely used to their full potential as a scientific resource. Follow our guidance and care tips to ensure they flourish in your lab.
