Grade 9: PBL Presentation

February 22, 2019

After a long but busy winter break, G9 students are back at school for the new semester! But before we start anything new, we must reflect on what we accomplished in the last semester. So today, February 22nd, during second and third period, 9 groups of students from 9 different PBL classes presented and explained the projects they conducted.

Several of the projects were experiments, including the fruit battery experiment, bacteria DNA extraction, anti-earthquake building design, and glow-stick creation! Many of the experiments required high tech tools and advanced procedures. This was especially true for the biology PBL. Jenny explained procedure of first checking soil for bacteria and then testing the bacteria for a certain disease. She had the privilege of extracting the DNA from the disease and showed color coded pictures of her results! It was all very impressive. In other PBL projects, students tried to solve issues like garbage disposal at SHSID or measure the quality of tea leaves. Leo gave an entertaining and impressive speech about his journey into finding how to measure the quality of tea leaves. Some projects were more curriculum based, such as behavior economics. The students in behavior economics first learned a lesson and then created a project. During their presentation, they showed some of their previous posters. There were very creative and artsy! As anyone can see, we accomplished much during the last semester. Let’s hope we achieve even more this semester!
