Separating funnel sim
Liquids that do not mix (immiscible) settle into two layers; the denser one forms the lower layer.

What the sim shows
Liquids that do not mix (immiscible) settle into two layers; the denser one forms the lower layer. Let them stand until the boundary is sharp. Take the stopper out first: with it in, no air can get in to replace the liquid leaving, so after a fraction of a cm³ the flow stops. Run the lower layer off through the tap, close the tap the moment the boundary reaches it, then change the beaker for the upper layer: the two layers must go into different containers. Densities (g/cm³): water 1.00, oil 0.92, hexane 0.66, dichloromethane 1.33. 50 cm³ of each.
- Lower layer: the denser liquid
- Right: what is in each beaker

- Bioleaching and phytomining simGrow plants on low-grade ore, burn them and dissolve the ash, or let bacteria leach a column of ore week by week, then get the copper out with scrap iron or electrolysis and weigh it.
- Earth's early atmosphere simDrag a timeline from 4.6 billion years ago to today and watch the oceans, algae, plants, limestone and coal appear; once the oceans form, carbon dioxide falls and oxygen rises; record readings and graph them.
- Methane and chlorine in UV light simShine a UV lamp on methane and chlorine in a graduated tube over water: with no UV nothing happens; with it the chlorine fades, oily drops form, the water rises, and CH₃Cl, then CH₂Cl₂, CHCl₃ and CCl₄ build up.
- Nanoparticles: surface area to volume simDrag a slider to cut a cube into smaller and smaller cubes, record the surface area and volume, and plot SA:V against 1/a to see why nanoparticles behave differently.
- Ozone layer and CFCs simOpen a CFC valve under a model atmosphere, let the years pass, and watch chlorine atoms thin the ozone layer and the UV index at the ground climb; then close the valve and see how slowly it recovers.
- Plastic waste and recycling simDrag six plastics to landfill, the sea, an incinerator, a pellet-making machine or a depolymerising reactor, and see what really happens, with the carbon dioxide and hydrogen chloride from burning worked out from balanced equations.
