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.

## Transverse Wave-Wavelength And Period(橫波波長與周期)

No votes have been submitted yet.

This simulation models a transverse wave traveling toward the right with a speed of V cm/s. Students can change the amplitude, wavelength, and period of the wave to observe their effects on the waveform. 此程式模擬一以波速 V (公分/秒)向右行進的橫波。學生可調控波的振幅，波長，與周期觀看此橫波隨時間波形的變化。

## Get Wetter If You Run E2(淋到多少雨E2)

No votes have been submitted yet.

A giant runs at velocity V in the rain from underneath roof m to roof n. His velocity (V) and the density of the rainfall (rho) can be changed. 此程式模擬在雨中以不同速度 V 奔跑的巨人，從屋簷 m 跑至屋簷 n 過程中淋雨的狀況。可調參數為奔跑速度(V)與降雨密度(rho)。

## 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.

## 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).

## 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。

## Role Of Carbon Dioxide During Respiration

No votes have been submitted yet.

This lab, through an experimental set-up, shows that carbon dioxide is released during aerobic respiration. This lab can also be used to study the effect of temperature on the rate of respiration.

## Study Of Plasmolysis

No votes have been submitted yet.

This simulations aims at demonstrating plasmolysis in peels of Rhoeo plant in hypotonic and hypertonic solutions using salt solution. Students can vary the concentration of NaCl and identify the type of solutions.

## Projectile Launcher(滑車接拋體)

No votes have been submitted yet.

This simulation models a situation where a sliding cart traveling on a flat surface launches a ball straight up after 1 second of travel. Assume that when the ball is launched, the net internal energy of the system does not change. Will the ball land back on the cart?

## Projectile Motion-Where Will It Land?(落在哪裡)

No votes have been submitted yet.

This simulation models a situation where a red ball is dropped or launched from the top of a moving truck. A truck travels with constant velocity Ve = -200 cm/s (moving to the left).

## Free Fall(誰先落地?)

No votes have been submitted yet.

This is a simulation of 4 objects with different forms and masses free falling from a height, either in air or in vacuum. 此程式模擬四種形狀，重量不同的物體，在空氣中與真空中於等高處自由落下的運動過程。
