Grade 7
Science Fair

Welcome to the 2021 virtual Science Fair!

This year 26 amazing Grade 7 students worked diligently over a period of six months developing a science project. During the first phase of this activity, students explored topics of their interest and came up with a specific research question. More research was then carried out to devise a suitable method to answer their question experimentally. They then conducted a series of preliminary experiments to test their methods and adjusted them accordingly. 

Throughout March and April students independently carried out their experiments and started to organise and process the data collected. They analysed their results to see if these supported their initial prediction and wrote a conclusion. Due to COVID measures we were unable to have a live fair at school, but we are still very happy to present to you the five minute videos where each student guides you through his/her project.

The Science Fair is an opportunity to teach Grade 7 how to use the Scientific Method to answer questions. This is the first time in Secondary School where they have to independently devise and conduct an experiment. The process is challenging, but will be tremendously helpful for all the future laboratory work they will complete in the coming years. 

I would like to thank all the Grade 7 students for their consistent effort and perseverance, and all the parents who supported them at home to successfully complete their projects.
