What the simulations are made for

Making the particle level visible

The particle level cannot be observed in a real experiment. The simulations present it alongside the substance level and thereby make comprehensible why a substance behaves in a particular way.

Adapted for smartphones

On a smartphone too

Almost all simulations are adapted in their presentation to smartphones. Extensive applications such as the molecule builder remain reserved for tablets or larger screens.

Easy sharing

Distributed quickly

Links and QR codes allow direct access without distributing files or installing programs.

All simulations at a glance

Sorted by topic area

Substances and particles

  • States of Matter Grade levels 8 to 10 Heat, cool, and compress water and follow in the phase diagram how the state point moves between solid, liquid, and gaseous.
  • Liquefied Gas: n-Butane Grade levels 9 to 11 Compress n-butane with the syringe plunger, switch between an oil bath and an ice-salt bath, and follow in the phase diagram when the substance becomes liquid.
  • Diffusion All grade levels Pipette dye into a beaker, change the temperature, and observe on both the substance and the particle level how quickly the dye particles spread out.

Intermolecular forces

  • London Dispersion Forces Grade levels 10 and 11 Switch between n-butane and isobutane, change the temperature, and have the formation of temporary dipoles shown step by step.
  • Hydrogen Bonds Grade levels 10 and 11 Choose water, ammonia, or a mixture, change the temperature, and observe how hydrogen bonds form and break again.

Molecules and structure

  • Molecule Builder All grade levels Assemble atoms into molecules, display bond angles and bond lengths, and rotate the molecule freely in space.
  • Molecule Duel Grade levels 8 to 12 Open a room, share the code or QR code, and let the class build organic molecules against one another – with a live ranking and a winners' podium.

Transport of substances

  • Osmosis All grade levels Add salt to one side of the U-tube, follow the change in water levels, and explain on the particle level why only water can pass the membrane.
  • Plasmolysis All grade levels Pipette hypotonic, isotonic, or hypertonic media onto the slide and observe under the microscope how the vacuole and protoplast respond.
