Primary School Grade 4: My Body System

In 4th grade science, our students were challenged to research a body system, build a model of the system, and present their models to peers. This year, students added more components to the project than in previous years. Their teachers uploaded various books and videos for each system to a file sharing website where the students could then download the materials for their research at home.

The students investigated the following topics related to their system:

·the system's parts and functions

·diseases associated with the system

·medical specialists and the instruments they use to treat the system

·Western or Chinese medical practices used for maintaining health in the system

Many students visited pharmacies and doctors to personally interview professionals and get acquainted with various types of medicine and medical tools.

The students record the sequence through which the system functions step by step onto note cards. For each step, they were encouraged to find an interesting fact to draw the attention of the audience. The note cards were checked by the teacher and then sorted into the best sequence. Information the students collected for their topics were written into sections and planned for the poster.

The students then compared their notes with the notes of other students researching the same body system. Students found this part of the PBA especially helpful, as they could see gaps in their knowledge and practice explaining the body system to their knowledgeable peers. Additionally, each group made a simple poster listing the facts they had learned about the system.

Finally, the students presented to groups of peers and every student had ample opportunity to ask questions and answer any questions that the presenter posed. All in all, our Body Systems PBA was a great success!
