Hello everyone,
Would anyone mind sharing your experience in teaching about principle of biotechnology and concept of DNA to high school students? I am planning to do a community service in that topic, but I have no experience in this kind of activity before. What kind of learning media should I use?
I am looking forward for your answers and suggestions. Thank you very much.
Hi,
I would suggest you to use Kahoot. This platform is quite easy and intuitive and is perfect for kids from 10-13 years old. It helps them to remember quite easily basic concepts such as introduction courses and the interactiveness of it makes the lecture more appealing.

They just need a computer or a mobile phone to start playing the game.
Best regards
I would also suggest hands-on experiments, which are quite easily and cheaply replicated in a classroom:
DNA: 1) Extaction of Student DNA, Fruit or Vegetable DNA (detergent, salt, alcohol) and show how long they are by pulling the DNA out of the cup with a pencil before the alcohol precipitation (got the thread to almost 1 meter.)
2) Principles of Genetics and Inheritence then test div. Phenotypes: curled tongue, attached ear-lobes, thumb extension, etc. (dependent on genetic diversity of region)
Biotechnology: 1) Lactose Free Milk (how its made) 2) Insulin (how its made) 3) Round-up ready seeds sprouting (farmers, seed distributors) and Round-up (glyphosate shouldn't be used indoors, possible carcinogen) 4) the original Biotech: beer, wine, vinegar or cheese.
Alot more ideas could be found in the internet. My tip: kids learn the most by combining hands-on activities (dependent on budget and resources) combined with teaching the concepts behind them. Depending on where you are from some of these suggestions might not be relevant, for different reasons.
Have fun, and kids always like when someone has fun with what they are teaching, that's when they learn the most.
Best Regards,
David
Hi,
I think you can easily read some papers as follow:
A study of certain biology and biotechnology concepts in secondary
school and high school course books in terms of scientific
competency

Istanbul University, Hasan Ali Yücel Faculty of Education, Department of Science Education, Vefa, Istanbul, 34070, Turkey
and also the following sites:

If you want to teach them biotechnology you should start from the basics, definition, types and application, as for the DNA, you need to teach them the 20 basic amino acids and it's structures first, then the sequence and paring method of proteins associated with DNA. It will make their comprehension of further studies easy. (*that's my method any way)
