Science Demonstration Series


Programme Title: "Scientists Symphony" Science Demonstration
Please click here for video.
Programme Description:

Have you ever seen the "rainbow flame" created from burning various metals? What are liquid nitrogen and liquid oxygen? Will materials behave differently under extremely cold temperatures? How do we make fluorescent liquid? Dr. Chan and Dr. Tong will show you the interesting worlds of chemistry and physics. To bring an exhilarating experience to your senses of sight and sound, the demonstration uses a new approach to unveil the mysteries of science through a series of experimental effects such as explosion, fluorescence, magnetic levitation and simulated lightning.

Speaker: Dr. Jason Chan (Assistant Professor of Science Education, Department of Chemistry, The Hong Kong University of Science and Technology) and Dr. Dominic Tong (Senior Lecturer, Department of Physics, The Chinese University of Hong Kong)
Language: Cantonese
Remarks: Jointly organised by the Hong Kong Science Museum, Department of Physics of the Chinese University of Hong Kong, and Department of Chemistry of the Hong Kong University of Science and Technology.

 


 


Programme Title: "Technologies of Gyroscope and Robotics" Science Demonstration
Please click here for video.
Programme Description:

Did you know that robots use gyroscopes to maintain balance? Gyroscopes have "very special properties" which makes them important in navigation among other things. Come and explore the amazing powers of the gyroscope and learn about its applications in robotics!

"The Elements of the Periodic Table" International Year of the Periodic Table of Chemical Elements Science Demonstration Lecture Series

The Periodic Table of Chemical Elements is one of the most significant achievements in science, capturing the essence not only of chemistry, but also of physics and biology. The year 2019 marks the 150th anniversary of its creation by Russian scientist Dmitry Ivanovich Mendeleev. The Year was proclaimed by the United Nations General Assembly as "International Year of the Periodic Table of Chemical Elements 2019" (IYPT2019). To support IYPT2019, Hong Kong Science Museum has invited Prof. Jason Chan, Assistant Professor of Science Education from the Department of Chemistry at The Hong Kong University of Science and Technology, to perform a series of extraordinary science demonstration, namely "The Elements of the Periodic Table". In the demonstration, he will showcase spectacular experiments and unique element samples, by which you will be taken into the world of the elements to explore their individual properties and listen to their fascinating stories.

 

Demonstration 1
Programme Title: Demonstration 1: Alkali and Alkaline Earth Metals (Group 1 and 2 Elements)
Please click here for video.
Programme Description:

The Group 1 and Group 2 metals are the most reactive metals. These metals can be rather unfriendly if they got wet, which could end up in pretty impressive explosions. The compounds of these elements, however, are very common in everyday life and can be found abundantly around our homes and within our bodies. In this demonstration, the properties of the groups 1 and 2 elements and their compounds will be demonstrated, featuring some of the famously reactive metals, such as Rubidium and Caesium!

 

Programme Title: Demonstration 2: Transition Metals: Part I (Group 3 to 12 Elements)
Please click here for video.
Programme Description:

There are so many interesting elements among the transition metals that two lectures will be devoted to their stories. In this first lecture, our attention will focus on the first row of the transition metals (Scandium to Zinc), and some of the most well-known metals are among these ten, such as iron and copper. These metals can display very beautiful and vibrant colours in their compounds and they will surprise us by their chemical reactions! We shall explore some daily life uses of these metals as well.

 

Programme Title: Demonstration 3: Transition Metals: Part II (Group 3 to 12 Elements)
Please click here for video.
Programme Description:

In this second lecture on the Transition Metals, we will focus our attention to the second and third row transition metals. Here we find some of the most expensive metals such as Gold and Platinum; some of the rarest metals such as Iridium and Osmium and some of the most elusive metals such as Mercury! In this demonstration, we will perform chemistry experiments with these expensive noble metals, these experiments are seldom performed – well, because not many are willing to give away their gold for Chemistry! Join us and be surprised by the properties of these heavier transition metals!

 

Programme Title: Demonstration 4: Boron, Carbon and Nitrogen Group Elements (Group 13, 14, 15 Elements)
Please click here for video.
Programme Description:

The common feature among groups 13 to 15 is that going from top to bottom, they switch from non-metals into semi-metals and into metals. As such, we can find rather diverse behaviours among these elements. How can carbon appear as sparkly and attractive diamonds, while the next element up, nitrogen, passes by only as a common gas that is in the air surrounding us? This demonstration will explore the chemical properties of these elements.

 

Programme Title: Demonstration 5: Oxygen group elements, Halogens and Noble Gases (Group 16, 17, 18 Elements)
Please click here for video.
Programme Description:

In the last three columns of the periodic table, are some of the elements with strongest personal characters. For example, the group 18 elements are noted for their nobility and inertness, while the halogens in group 17 are some of the most reactive and dangerous non-metal elements. While oxygen is breathed by all to survive, you may wish to stay away from the other oxygen group elements as they could bring about unpleasant effects to your body. Learn all about them at this demonstration!

 

Programme Title: Demonstration 6: The Lanthanides: Rare Earth Metal Elements
Please click here for video.
Programme Description:

The lanthanide elements are often listed as a separate block on Periodic Tables alongside the Actinides. These fifteen members (La to Lu, 57 – 71), known as the rare earth metals, are not very well known by most; but they do have many unique and beautiful properties, making them highly useful in the modern society. In this lecture, we will take a look at these rare earth metals' properties and reactions. We will also explore why they can be found in a variety of useful applications.

 

Programme Title: Demonstration 7: The Actinides and other man-made elements
Please click here for video.
Programme Description:

The Actinides starts with Actinium (Ac, element 89) and all elements beyond them are radioactive elements. Their atoms are all too unstable that they naturally decay into smaller, more stable atoms. Some of these radioactive elements are found naturally, but many of them are made synthetically in the lab. In this lecture, some items containing these elements will be shown to allow us to appreciate their uses; and we would also discuss how new elements are made by scientists in the lab. At the end we will explore what's next for the Periodic Table after element 118.
