LabsLand is a global network of real laboratories available online. Students (in schools, universities and life-long learning platforms) can access the real laboratories through the Internet, using their laptop, tablet or phone.

The laboratories are either real-time (Arduino, FPGAs...) located in different multiple universities all over the world. In certain fields (Physics, Biology, Chemistry) the laboratories are LabsLand Ultraconcurrent Laboratories, so the university has recorded all the potential combinations of what can be done in the laboratory (in some cases, several thousands) and make it available in an interactive way.

In every case, the laboratory is always real (not simulated), and available through the Web (you do not need to obtain any hardware, deal with shipping, etc.).

Check how a typical user session works in the following video:

Study how alternating current (AC ) works by experimenting with several bulbs connected in series and / or parallel. Opening or closing the switches you want, you can see the effect on the intensity of light of each of the bulbs of the created circuit.

Experiment with buoyancy, the Principle of Archimedes, and similar physical laws. Take related measurements, conduct experiments, and start doing relatively advanced calculations to draw conclusions.

Summary

The Boyle's Law laboratory allows students to determine the relationship between the pressure and volume of a gas at ambient and constant temperature. Students can choose from two different volume syringes and measure the pressure of the gas as they reduce the volume. The experiment is reflected in a graphical analysis in the form of an isotherm. In this way, they can verify Boyle's Law and learn about the behavior of gases in a practical and accessible manner.

 

Boyle's Law

Boyle's Law states that at a constant temperature, the volume of a gas is inversely proportional to its pressure. This means that when the pressure of a gas increases, its volume decreases, and vice versa. Boyle's Law can be mathematically expressed as:

V ∝ 1/P

Where V is the volume of the gas and P is the pressure of the gas.

The Boyle's Law laboratory allows students to put this law into practice and verify it in an experimental context. By measuring the volume and pressure of the gas at different times, they can plot an isotherm graph that shows how the volume of the gas changes based on its pressure. If the isotherm graph fits Boyle's Law, then the students have experimentally verified the law.

Performing experiments like this is an excellent way to learn about the behavior of gases and how different variables are related. In addition, hands-on experiments can be more accessible and memorable for students than simply reading about the law in a textbook. The isotherm graph clearly visualizes the behavior of the gas and verifies if the predictions of Boyle's Law are met.

 

Application in Secondary and University Education

The Boyle's Law laboratory is typically applied in science courses at the high school level and in chemistry courses at the university level. At the high school level, the laboratory can be applied in a science course where the basic concepts of chemistry and physics, such as the pressure and volume of gases, are studied. At the university, the Boyle's Law laboratory can be applied in a more advanced chemistry course where the study of gases and their behavior is delved into.

Summary

The Multi-Phase Flowloop laboratory lets you carry out experiments to visualize flow patterns of multi-phase systems that develop in production tubing in possible real-life scenarios. Through variation of the water flowrate and the angle of the tubing itself, you can appreciate the forming of different flow patterns or “cuttings” depending on the chosen values.

 

Further details

Multi-phase systems are found in various industrial scenarios, not being an exception the oil and gas industry. The prediction and determination of the flow pattern in the production tubing is of great importance since this is directly involved with the optimization of the production itself.

Mixtures of hydrocarbons, water, sediments and gases found in reservoirs manifest different behaviors during their transportation to the ground’s surface. Predicting such behaviors enable a better understanding for adequate choice of pumping machinery and pipeline setups for a successful transport to their final processing facility. The Multi-Phase Flowloop test unit helps achieving a better predictiveness of how multi-phase systems behave in real life for further investigation. This enables the user a better comprehension and visualization of how multi-phase transportations react under variable production rates and mixture proportions.

Summary

The remote laboratory offers a convenient way for schools and universities to conduct experiments on gravity and energy conservation. Students can choose from a variety of objects with different masses and release them using an electric switch.

Free-fall

Free-fall is a phenomenon that occurs when an object falls under the influence of gravity alone. This can be observed by dropping an object from a certain height and watching it accelerate towards the ground at a constant rate. In schools and universities, free-fall experiments are commonly used to help students understand and explore the fundamental concepts of gravity and energy conservation. These experiments typically involve releasing an object from a known height and using a receiving device to measure its time of fall, allowing students to calculate the acceleration due to gravity and conduct other experiments related to free-falling objects.

In a free-fall experiment, students can carefully measure the initial height of the falling object and the time it takes to reach the ground, allowing them to calculate the acceleration due to gravity. Students can also experiment with different objects of varying masses to see how the acceleration due to gravity changes based on the mass of the object. In addition to helping students understand the basic principles of gravity and energy conservation, free-fall experiments can also be used to explore more advanced concepts in physics. For example, students can experiment with objects that have different shapes and densities to see how these factors affect the rate of free-fall. They can also use the results of their experiments to make predictions about the motion of objects in real-world situations, such as the motion of a skydiver or a satellite in orbit around the Earth. Overall, free-fall experiments are an engaging and effective way for students to learn about the fundamental principles of physics.

Radioactivity is the process in which an atomic nucleus loses energy by emitting particles and radiation. This can occur naturally in certain elements, or artificially through the use of nuclear reactions. In the context of physics at schools and universities, studying radioactivity can provide valuable insights into the fundamental nature of matter and the laws of physics.

One common experiment in this area is the measurement of radioactivity using a Geiger counter.

By varying the type of radioactive source, the distance between the source and the detector, and the type of absorber material placed between the two, students can explore a wide range of phenomena and gain a deeper understanding of the underlying principles.

In addition to its educational value, studying radioactivity also has practical applications in fields such as medicine, energy production, and environmental protection. As such, it is an important topic for students to learn about, both for its intrinsic interest and for the many real-world applications it has.

 

Real-world applications of radioactivity

Radioactive isotopes are used in medical imaging techniques such as PET and SPECT scans, which allow doctors to see inside the body and diagnose diseases. Radioactive isotopes are also used in cancer treatments, such as radiotherapy, where they are used to kill cancer cells.

Radioactivity is also used in industries such as oil and gas exploration, where it is used to measure the permeability of rock formations and the flow of fluids through them. Radioactive isotopes are also used in smoke detectors and in the production of luminous watches and instruments.

Overall, radioactivity has a wide range of applications in fields such as medicine, industry, and even everyday consumer products. It continues to be an important area of study in physics and other sciences, and its uses continue to expand as new technologies are developed.

 

Radioactivity experiments at schools and universities

The use of a geiger counter in a radioactivity experiment allows for a wide range of possibilities. By varying the radiation emitters and absorbers, students can observe the effects of different sources and materials on the detected particle collisions. This can help students understand the properties of radioactivity and the behavior of different particles.

Additionally, experiments involving the determination of the type of particle being radiated can be conducted by observing whether the particle is absorbed or not. By placing different absorbers between the source and the probe, students can determine the properties of the emitted particles and gain a deeper understanding of radioactivity.

Lastly, experiments involving the determination of the geometric form of radioactivity emission can also be conducted using a geiger counter.
