On Thursday 21 February 2019, during school half term the Walley group were at the Victoria Gallery and Museum (VGM). We took with us a display of cultivated brassica crops, and their crop wild relatives to demonstrate how over many years the weedy Brassica oleracea crop wild relatives have been domesticated and bred into so many different vegetables through selection.
Visitors had a go at performing crosses between different brassica crops by transferring pollen between flowers using paint brushes and, inspired by how new vegetables can created, such as flower sprouts or ‘Kalettes’ (crossing a sprout with a kale plant), designed their ideal or fantasy brassica plants for us to display.
The methods of modern plant breeding that we are using within the BRESOV project (Breeding for Resilient, Efficient and Sustainable Organic Vegetable production) were discussed and compared to conventional plant breeding.
Visitors had the opportunity to taste many of the different vegetables derived from wild Brassica oleracea, including cauliflower, sprouts, kale, kalettes, red cabbage, pak choi, chinese cabbage and broccoli- they were very popular!

On Wednesday 31st October 2018 IIB and SoLS held the first Institute-wide School Engagement event within the Life Sciences Building. 82 children from Banks Road, Litherland Moss Primary Schools and home-schooled pupils from the local area attended the morning session with 128 Secondary school children from Notre Dame Catholic College, Prescot School, Kings Leadership Academy Hawthornes, Academy of St Nicholas, Archbishop Blanch and St Michaels High attending the afternoon session.
Pupils took part in a range of fun spooky science activities:
- exploring relationships between skulls and other features of animals (e.g. diet and faeces!) with Michael Berenbrink and PhD student Kelly Ross
- finding out about blood flow and gravity, how holding your breath slows your heart and which animals that make your heart race with SoLS Terry Gleave and Rachel Floyd
- making zombie proteins out of magnetic beads with Luning Liu and Fang Huang, assisted by many students
- looking at model organisms under the microscope with the Centre for Cell Imaging (CCI – Violaine See, Dave Mason, Jen Adcott, Daimark Bennett, Anne Herrmann, Marco Marcello and PhD students Kit Sampat, Hammed Badmos, Rebecca Kelly)
- finding out how much protein is in the foods we eat including fishing in cauldrons for the answers from the Centre for Proteome Research (CPR – Kimberley Burrow, Jos Harris, Victoria Harman and PhD students Max Harris, Rosie Maher, Iris Wagner, Natalie Koch)
- pupils could also get up close and find out more about a range of animals kindly provided by staff from World Museum and from within SoLS with Carl Larsen
Additional student and staff helpers including Alice Clubbs Coldron, Lauren Tomlinson, members of Jill Madine group (Hannah Davies, James Torpey and Alana Maerivoet), Louise Colley and Laura Winters were invaluable in organising the day and logistic arrangements on the day.
This month, a group of research students and postdocs developed an interactive workshop exploring the world of plants. This workshop was taken to two events: one with a local Brownie troop and then to a Meet the Scientists event at the World Museum in Liverpool. We came up with the activities by first identifying interesting facts about plants that we wanted to communicate, and built the activities up from there. The three key things that we highlighted were circadian rhythms, leaf adaptations, and the importance of soil pH.
Circadian rhythms are an internal mechanism that acts like a body clock, which plants use to survive. To introduce this complex concept to a young audience, we created a card pinwheel that showed the times at which different flowers open. This idea was based on the concept garden designed by Carolus Linnaeus in 1751. The pinwheel contained outlined drawings of flowers that could be coloured in by visitors whilst the demonstrator chatted to them about circadian rhythms. Our card Linnaeus clock is available to download here.
To demonstrate that plants can recognise the pH of the soil that they are in, we brought some pH indicator that had been made using red cabbages. Red cabbage indicator is purple at a neutral pH, but can change to bright yellows and pinks on the addition of household substances such at lemon juice or washing powder. Visitors were encouraged to test the pH of a selection of different items, as well as testing soil samples. Photographs of hydrangeas were on display to show how drastic an effect soil pH can have on plants.
To demonstrate leaf adaptations, we took a two pronged approach. For older children and adults, a microscope was available to look at details such as veins and stomata on leaves from a variety of plants including local deciduous trees, an ornamental conifer, and a Christmas cactus. While some of the visitors enjoyed looking at the leaf structures, it became clear that some aphid eggs found on a sycamore leaf was more interesting! For the younger visitors, materials for making leaf rubbings were provided. By making leaf rubbings, we were able to encourage the younger children to look at the leaves more closely and to examine their different shapes. We then cut their leaf rubbings out and attached them to headbands, something which helped draw more people to our table.
