Scholars and professors from Beihang University and other universities and research institutes have prepared interesting science and technology activities for students. After learning some prior knowledge, students will complete challenging tasks under the guidance of teachers, such as designing various science projects, building scientific instruments or coding computer programs. Finally, science competitions will be held to evaluate their learning outcomes.

A1-Investigation on the use of nanosilver in consumer goods and silver health risk assessment to adult consumers

Nanomaterials refer to materials with at least one dimension in nanometer size (1-100 nm) in three-dimensional space or composed of them as basic units, which have been widely used in many fields. Due to good antibacterial properties of nanosilver (AgNP), the Woodrow Wilson Center reported that about 24% of all known products containing nano materials contain AgNP.

The research of this project includes two aspects:

(1) You will investigate which consumer goods around us (such as personal care products, electronic products, household products, etc.) contain AgNP. Please list their brand, name, purpose, form (including status such as solid or liquid, color, etc.), usage mode (external or oral), price, etc;

(2) When cleaning consumer goods, AgNP in them will release silver ions, which would make potential risks when human exposure through skin contact or oral administration. According to the human exposure health risk assessment model recommended by the U.S. Environmental Protection Agency and relevant parameters, please assess the health exposure risk of silver in consumer goods containing AgNP. The results would provide a reference for the scientific management of AgNP in the future.

A2-A virtual robot who can write and draw

There are many kinds of robots in the world that play important roles in our lives. Some can help people do housework, some are used in production lines and some can even be used to explore Mars. In this activity, we will acquire an intuitive understanding of the robot who can write and draw through a virtual robot platform. First, the mechanical structure and operation process of an acupuncture robot will be introduced. Then, I am going to demonstrate how to control the robot to write and draw. Lastly, you will choose a Chinese Character (such as“中zhong”、“平ping”、“直zhi”、“美mei” ) or design what you like within the specified time to make the robot draw.

Materials to prepare: A4 paper, pencil, ruler, eraser

A3-Virtual Simulation of Aviation Emergency Rescue Systems

Virtual Simulation of Aviation Emergency Rescue Systems is led by Beihang University, guided by 999 emergency rescue center of Beijing Red Cross Society and jointly developed by Beijing KeyRays Interactive Technology Co., LTD. It is the first part of a series of virtual simulation experiments about Exploration and design of Aviation Emergency Rescue Systems. The series of experiments focus on the major needs of the construction of national aviation emergency rescue systems. It is divided into aviation medical, maritime rescue, forest fire fighting, earthquake rescue and other topics. The purpose is to make students through virtual rescue task master and use the method of systematic design and to train students ability to solve complex problems based on system analysis.

The experiment of "exploration and design of aviation emergency rescue systems " includes two stages. The first stage is exploration on aeromedical rescue scene and tasks. Students can not only roam virtual ice and snow sports scenes, but also experience aeromedical rescue scene and task "in person" by playing the role of the captain of the rescue helicopter, medical staff and other roles. Thus students can have an intuitive understanding of the elements of the aviation emergency rescue systems. The second stage called the design and optimization of aviation emergency rescue systems is the main part of the experiment. Students can form teams, comprehensively consider the terrain of the stadium constraints on the type and number of search-and-rescue helicopters and combine with rescue rules to complete the selection of takeoff and landing points , the design of system elements such as aircraft configuration and deployment and form a variety of alternative system design schemes. The team can carry out multiple rounds of simulation deduction for each scheme. Under the influence of various possible rescue needs and uncertain factors, the team comprehensively evaluates the response process and task time-consuming evaluation indicator of different schemes, forms the research report and selects optimal scheme finally. The optimal scheme of different teams can be used as the basis for further competition.

The research and design of aeromedical rescue system has been used in undergraduate teaching of Beihang University, and was a part of the MOOC in the English version of Aerospace Technology. Through the English version of MOOC platform, it is planned to explore a new online teaching mode of international MOOC+ virtual simulation experiment.
