Heart rate66 bpm Pump it yourself

Watch a heart work, then pump it yourself.

Spin the live 3D heart and follow the blood round the body. Made for Sec 1-4/5 biology.

Open simulation

Three simulations, ready to use

Each one ends with a quiz. Pick an activity to jump straight to it.

Interactive Heart

Click through the heart on a cross-section or a 3D model, follow the blood, and slow one beat down on a live ECG.

A conical flask of Universal Indicator solution A glass conical flask part full of liquid. The liquid colour follows the pH slider: red at pH 0, orange, yellow, green at pH 7, blue and then purple at pH 14.
pH 3, weakly acidic

Acids, bases and pH

Read the colour of Universal Indicator, run a titration to its end point, and test how acids react.

A test tube of potassium iodide solution turning brown as bromine water drips in A glass dropper holds orange bromine water and lets a drop fall into a test tube of potassium iodide solution. The solution is turning brown, the colour of the iodine that is displaced, with a little orange at the surface where the bromine goes in.
Bromine displaces iodine

Halogen displacement

Add a halogen to a halide solution and see whether it displaces a less reactive halogen from its halide. Reactivity falls down Group 17.
