Science Fair is so much fun!
My first experience with Science Fair was in a London school, my head of department said she had been sceptical at first but found that she could teach much more efficiently after the cohort had gone through the experience.
When I started work in a Danish school, I decided to have an annual Science Fair for my 7th and 8th graders. I am so glad that I did! I have some great photos and videos to remind me of their hard work and engagement with science. In that school, there was no way of setting up a hall with poster boards of results, so we just had to demonstrate the experiments to the younger students in the lab. This worked well but of course, students were able to blend in the crowd a little too much and were not put on the spot as much as I would have liked.
Now I am working on Science Fair in my current school. We have a hall that I can use, so I am keen to have them present their results in a more public way. We also have links with the local business and academic community, so I am hopeful we can involve them.
