This space teaching activity will continue to be conducted through interactive methods between heaven and earth.

Three astronauts will showcase and introduce the work and life scenes of the Chinese space station's Mengtian experimental module in orbit, and carry out multiple related experiments.

The spherical flame experiment will demonstrate the phenomenon of spherical flames produced by candle combustion in microgravity environments, explain the influence of gravity on the combustion process, and the important significance of studying combustion in microgravity environments

The wonderful "ping pong ball" experiment will use a "specially made" ping pong ball to hit water balls, explaining the surface tension of water and the structural characteristics of hydrophobic materials

The momentum conservation experiment will demonstrate and explain the center of mass collision phenomenon of steel balls with different masses in microgravity environment

"Space turning" will also be reproduced, and the gyroscopic experiment will demonstrate the conservation of angular momentum in a microgravity environment using a metal gyroscope under both stationary and rotating conditions.

Looking forward to the presentation of the fourth lesson of "Tiangong Classroom"

Do you remember what exciting content was in the first three lessons

Let's review together

Tiangong Classroom

Experiments such as spherical flames are included in the curriculum, and the "Heavenly Palace Classroom" will resume today

Buoyancy disappearance experiment

On the ground, when a ping pong ball is placed in water, it will float to the surface of the water. So, when conducting the same experiment in space, will the ping pong ball float or not? The answer is - not floating!

Tiangong Classroom

Effervescent tablet experiment

After encountering water, effervescent tablets usually produce many bubbles. So what happens when effervescent tablets meet water balls in space? The answer is - to become a joyful "bubble ball", and fragrance wafts in waves!

Tiangong Classroom

Water Ball Optics Experiment

Injecting water into the water film results in a water ball. Then a bubble was injected into the water ball, and a magical scene appeared - through the water ball and bubble, two images, one positive and one negative, could be seen. What's going on?

Tiangong Classroom

Space "Ice and Snow" Experiment

In the Chinese space station, where the seasons are like spring, astronauts have created a crystal clear "ice ball" - a liquid ball crystal. The appearance looks like a "hockey ball", but it is actually a "hot ball"! What is the principle behind it?

Tiangong Classroom

Liquid bridge demonstration experiment

Under the gravity environment of the ground, the surface tension of water is negligible. So, how strong is the surface tension of liquids in the microgravity environment of space? The astronauts built a "bridge" with liquid!

Tiangong Classroom

Water and Oil Separation Experiment

On the ground, water and oil mix and naturally layer, with oil above and water below. Will water and oil naturally separate in a space station? The answer is - no!

Tiangong Classroom

Water Ball Becomes Lazy Experiment

When astronauts use a syringe to spray air into a water ball, the vibration of the water ball is very intense; After adding a steel ball to the water ball, the vibration amplitude of the water ball decreases with the same force of impact! What's going on?

Tiangong Classroom

Space fun drinking water

On the ground, if the straw is too long, it takes a lot of effort to drink the drink. In the experimental module, the astronauts not only successfully drank mango juice with a 2-meter-long straw, but also expressed that it was "very easy".

Tiangong Classroom

A wrench that can turn around

After the astronauts rotated the T-shaped wrench, a tool in the space station, in the air, the wrench actually flipped over on its own! Sometimes head up, sometimes head down, repeatedly. Even more miraculously, when two wrenches are rotated simultaneously, they exhibit completely different rotational postures!

The universe is vast, exploring infinity

Minister of Ukraine called it "unbelievable", foreign media: nearly half of Kiev's air defense tunnels cannot be used for time | inspection | Kiev

According to the report on the website of Singapore's Lianhe Zaobao on June 5, a preliminary inspection conducted by the Ukrainian government showed that nearly half of the air raid shelters in the capital Kiev were closed or did not meet the use standards. Ukrainian Minister of Strategic Industry, Kameshen, called this "unbelievable". According to reports, on June 4th local time, Cameron stated that out of the 1078 air defense facilities visited on the first day of inspection, 359 were not ready, 122 were locked, and only 597 were operational. He said on social media "Telegram", "The fact that only half is open and ready is unbelievable to me. When we and the Mayor of Kiev selectively inspected the air raid shelters in the Obolon district, the vast majority of them were closed." The report stated that Cameron said the inspection work would continue. On June 1st,

Taiwan media pays close attention to the "Incense Gathering": Taiwan related issues and speeches by the defense ministers of China and the United States are the focus of attention. China | Minister of National Defense | Incense Gathering

The 2023 Shangri La Dialogue will conclude in Singapore today, with representatives and scholars from more than 40 national defense departments, including Chinese State Councilor and Defense Minister Li Shangfu and US Defense Secretary Austin, attending the dialogue to explore ways to maintain peace and stability in the region. The speeches of the defense ministers of China and the United States and their movements at the conference have attracted attention from all parties, and the focus of Taiwan media has been on the Taiwan Strait issue. Taiwan media has been closely following the "Incense Gathering". Several Taiwanese media outlets have continued to report on the event, and Taiwan's United Daily News has focused on China's Defense Minister Li Shangfu's speech titled "China's New Security Initiative". The article cites the speech content and emphasizes that if anyone dares to split Taiwan from China, the Chinese military will not hesitate at all and will not fear any opponents. No matter how much the cost is, they will resolutely uphold it

What kind of grievance does the United States pretend to be?, Xiake Island | Termination: The defense ministers of China and the United States did not fulfill their request. US | China US | United States

The United States has been wronged again. Recently, the US Department of Defense has been complaining everywhere, saying that China has rejected the US request for a meeting between the US and China defense ministers. Subsequently, American media intervened and claimed that the US had made several weeks of efforts to ensure this meeting, Barbara... At first glance, it seems that China is not giving the US the opportunity and face, but since it is the US who is complaining, the matter needs to be pondered. At present, the 20th Shangri La Dialogue is being held in Singapore, with Chinese State Councilor and Defense Minister Li Shangfu invited to attend. The proposed "China US Defense Ministers Meeting" by the US aims to have US Defense Ministers Austin and Lee Sang fu meet in Singapore. Originally, the debut of the newly appointed Chinese Defense Minister's "Xianghui" was highly anticipated. But the Chinese side hasn't said much yet, and the United States has taken advantage of the heat first - on May 30th, the United States

Four Questions on the US Debt Crisis Observation | Xinhua News Agency | Crisis

Beijing, June 2 (Xinhua) - The United States Senate voted on the 1st to pass a bill on the federal government's debt ceiling and budget, which will take effect after being signed by President Biden. Although this round of US debt ceiling crisis has temporarily eased, the outside world has increasingly questioned the origin, capital flow, sustainability and huge risks of the huge US debt. These issues are intertwined with issues such as US dollar hegemony, US party struggles, and US corruption, becoming a "gray rhinoceros" that threatens global economic and financial security. In response to the four major concerns about the US debt crisis, which have been highly concerned by the outside world, Xinhua News Agency reporters have traced the root cause and clarified its origins.
