Online labs provide your students with the possibility to conduct scientific experiments in an online environment. Remotely-operated labs (remote labs) offer an opportunity to experiment with real equipment from remote locations. Virtual labs simulate the scientific equipment. Data sets present data from already performed lab experiments. Please use the filters on the right to find appropriate online labs for your class. Labs can be combined with dedicated Apps to create Inquiry Learning Spaces (ILSs).

If you are looking for online labs especially suitable for the curricula of Benin, Kenya or Nigeria, please visit our Collections page.

## Density And Buoyancy(密度與浮力實驗)

No votes have been submitted yet.

This simulation models the process of putting an orange block of mass M (g) and volume V (cm^3) into a blue solution with density rhoS (g/cm^3) in order to investigate the concept of buoyancy.   此程式模擬將一個重量為 M 公克，體積為 V 立方公分的橘色方塊慢慢浸入密度為 rhoS (公克/立方公分)的藍色溶液中的過程，以探討浮力概念。

This simulation explores the effect of frictional force in a scenario where two objects stacked on top of each other are subjected to a an external force. Can you figure out the relationship between Ma and uab so that the present does not slide off the sled?

## Micrometer

No votes have been submitted yet.

This is a close visualization of a micrometer. It helps students to practice reading the measurements of this device.

## Buoyancy-Float Or Sink(浮力應用-浮或沉)

No votes have been submitted yet.

This simulation models the process of two sinking pieces of clay with equal densities and masses but different shapes. Here’s a question: When describing ship sizes, the term “displacement (tonnage)” is often used. Why?

## Pascal's Law

No votes have been submitted yet.

This lab helps to visualize Pascal's Law to understand the underlying principle.

## Perfectly Inelastic Collision(子彈測速)

No votes have been submitted yet.

This simulation models a scenario where a bullet is shot at a velocity Vb into a pendulum, based upon the ballistic pendulum devised by English mathematician Benjamin Robins in 1742. 此程式模擬一顆以速度Vb的子彈射入一擺錘的運動過程，同理於西元1742英國數學家羅賓斯所設計的子彈測速儀器模型。

## Glucose Dilution Problem

No votes have been submitted yet.

In this activity, students use the virtual lab to create a 0.025M glucose solution from a standard 1M glucose solution. First, they calculate the correct volumes of 1M glucose solution and water to mix together to create the final 0.025M solution.

## Dynamic Pendulum System

No votes have been submitted yet.

This simulation allows students to connect pendulum oscillations with the formula and the graph describing it.

## Resonance

No votes have been submitted yet.

This simulation visualizes resonance of a sound wave. Students can change the level of the water and hear the sound.

## Buoyancy-Submarine(潛水艇)

No votes have been submitted yet.

This simulation allows the student to control the depth of a submarine's submersion in water. The submarine has a mass of 30000 grams and a volume of 52500 cm^3 and is floating upon the surface of the ocean at the start of the simulation (density of seawater: 1.03 g/cm^3).
