PYP Grade 4 Explores Body Systems 探索人类身体中的小秘密

This past Wednesday, Classes 4.1 and 4.2 went on a field trip to the Beijing Natural History Museum. The purpose of the field trip was to explore the various components and functions of the human body systems.


Prior to leaving for the field trip, students wrote down some burning questions they had about our current unit. These questions included inquiries like:


– How many body systems are in the human body? (Eva, 4.1)


– Are the organs of people now the same as the organs of people in the past? (Wei Wei, 4.1)


– What do the body systems look like? (Domi, 4.1)


– Which body system is the most important? (Kevin W., 4.1)


– Why do we need a digestive system? (Grace, 4.1)


– How can lymphatic system help us? (Nancy, 4.2)


– What does red blood vessel and blue blood vessel do? (Olivia, 4.2)


– What does a human bone look like? (Solomon 4.2)


– How does our body system work together? (Sunny, 4.2)


– What is the function of a nervous system? (Peggy, 4.2)


Students left the school with questions and a mindset ready for learning.


During the field trip, students explored two key exhibits. One exhibit featured the human body systems in various, exciting ways. There were posters, diagrams, models, and interactive games on many body systems. The other exhibit explored the evolution of humans and included models that displayed how the human body structure has changed over time. Grade 4 students visited these informational areas and used a worksheet to take notes and record information. Students had the freedom to record the information that interested them and was related to our unit. Students were also encouraged to use note-taking strategies we learned in class, such as summarizing main points and organizing information in different ways.



After the field trip, students used their notes and their learning to write a reflection on the day. Reflection is important because it gives teachers the opportunity to see what aspects of the field trip and learning made an impact on students.


The field trip relates directly to Grade 4’s currently ongoing Who We Are unit. Both classes are exploring several different key body systems, including the skeletal system, circulatory system, nervous system, muscular system, respiratory system, and digestive system. The students are also briefly exploring other systems such as the lymphatic, endocrine and reproductive systems.

这次体验活动与四年级国际班主题为“Who We Are? 我们是谁?”的探究单元相结合。我们探讨了几种不同的重要身体系统,包括骨骼系统、循环系统、神经系统、肌肉系统、呼吸系统和消化系统。学生们还简要地探索了其他系统,如淋巴系统、内分泌系统和生殖系统。

Currently, students are synthesizing all the information they’ve collected into a flipbook where they demonstrate their understanding by labeling and writing about each body system. In the next few weeks, students will also explore the interdependence of body systems and how lifestyle choices impact human health.
