Taking Science To The Public Is Addictive –DNA detectives at the 2018 Brighton Science Festival

My interest in science was fed by occasional documentaries and the hands-on activities at The Science Museum and Natural History museum. Accessible information is now available on every platform, but where do the the youth of Sussex get to join in with hands-on activities?

The Brighton Science Festival

Just under three weeks to go until the Bright Sparks weekend provides hands-on activities at the Brighton Science Festival. And we get to join in! The DNA Detectives – a group of researchers, students and faculty from the University of Sussex School of Life Sciences will be extracting DNA from strawberries and making models of viruses with 100’s of young people.

Thank you to The Royal Society for Biology for sponsorship.

Thank you to researchers, students and faculty for their time.

Thank you to Brighton Science festival for giving us the opportunity to have fun undertaking this important outreach.

Short Burst Activities in Lectures Part 1. Herd Immunity

Short Burst Activities – Introduction.

My teaching philosophy is that the most effective teaching fosters an active participation in learning and in my roles as a University professor and as a leader of outreach activities I consider myself primarily as a learning facilitator.

A worked example makes it easier for others to understand how readily this can be achieved and so I am compiling a series of ‘how to’ guides for ‘Short Burst Activities’ within lecture theatre teaching teaching of Bio-Sciences. Some are very specific but others could be readily adapted to other topics.

I would be greatful for feedback and if you would like me to add your activities to the blog, or add a link to them please contact me.

Part 1. Herd Immunity

Learning Objectives: to illustrate the value of herd immunity (year 1 BSc)


In advance bring a method of identifying a set of students eg napkin on head.

  • Give a set (approx half the class) of napkins to some students in middle of the front row
  • Instructions are to take one and pass backwards (2 minutes)
  • If available give a toy to two students on left hand side to represent vunerable people
  • Set an infection going in one corner of the class (right hand corner in illustration)
  • Instructions are to stand up when infected and to pass the infection by shaking hands with anyone you can reach easily
  • After a couple of minutes you will see that the majority on the right hand side are infected and none on left hand side are
  • If your lecture/teaching space is not full then the immunization will be patchier and the results less clear (as in life)
  • Watch the spread of infection and pause transmission at an early stage to illustrate some herd protection then let it continue to show a poor outcome
  • Then either cluster the students together to re-run or show the diagram of the outcome with good coverage
