北京君誠學校為學前班至十二年級的學生都提供了豐富的科學課程。君誠的課程標準根據美國的下一代科學標準(Next Generation Science Standards)或NGSS而設定。教師會建立以科學探究為基礎的課程，并制定適當的目標，以加強學生對于科學原理和技能的學習。低年級的學生會有充足的時間來獲取科學基礎的概念，并開始自行探索世界。

　　SIBS offers a robust science experience from KG to grade 12. Our guiding standards are drawn from Next Generation Science Standards or NGSS from the United States. Teachers are encouraged to build inquiry-based learning experiences with appropriate targets to enhance the learning of science principles and skills. Early childhood students have adequate time built into their days to explore basic science concepts and begin to investigate the world around them.

　　學前班至五年級的教師們使用的是Reading Street系列的課程和書籍。隨著君誠在逐步實施PYP(IB課程的小學階段)的課程內容，教師們將參與并重新編寫IB課程體系PYP階段的單元課程，所需的教學資源在美國和中國都可以被找到。小學的學生需要大量的資料來支持他們對于科學的探索。從四年級開始，學生就會在教師引導下，正式接觸1對1的電腦程序，該計劃支持學生進行科技研究，以及探索電子電路和工程學。君誠學校中學部也開設了STEM課程，學生可以開始嘗試編程以及一些基礎的操作，例如操縱機器人和無人機等等。

　　KG3 - Grade 5 teachers use a Reading Street series in order to deliver some of the material. However, as the school moves towards PYP units of inquiry, teachers will be engaged in writing units with a PYP framework for IB implementation. In the interim, resources that are required are found in the US and within China. Students in ES utilize a large range of material to support them in their scientific quest within the classroom. Currently, grade 4 is piloting a 1 v 1 laptop program that has allowed students to use these devices to support investigation and electronic circuitry and engineering. This will be essential as we move forward in establishing our STEM program in Middle School. Students experiment with programming and beginning to establish the basic levels to manipulate devices such as robots and drones.

　　STEM課程是君誠學校中學部的發展重點，我們的目標是開設一個基本的綜合科學課程。學校理科教師團隊一直在探索如何在未來的兩到三年內建立MYP課程(IB課程的初中階段)，努力為十年級學生順利完成DP課程(IB課程的高中階段)的過渡做好準備。

　　Middle School employees a basic integrated science program with an emphasis on STEM. Our science department has been exploring how to establish MYP over the next 2-3 years. Our teachers are working hard to establish understandings in this area in hopes that students will enter grade 10 ready to successfully complete DP science courses. 君誠高中部擁有著寬敞的現代化的實驗室，十分適合開設IBDP課程。君誠已經為建設北京的實驗室設施投入了大量資源。在君誠任教的老師都是在國際學校任教多年的經驗豐富的優秀教師。他們在協同工作，為君誠學子提供的學習體驗。 SIBS High School science labs are modern, spacious and fitting for successful courses for the IB DP. SIBS has dedicated a great deal of resources to state of the art lab facilities. Our teachers are experienced international school science teachers who are working collaboratively to support the best educational practices regarding science instruction.
