Java via CheerpJ:
We've partnered with Leaning Technologies to allow our Java sims to run in a browser.
This sim is not compatible with iPads.
Java Version:
Supports offline use and offers improved performance.
Indhold
- Gas
- Opdrift
Beskrivelse
Lav eksperimenter med en heliumballon, en varmluftballon, eller én med atmosfærisk luft - 3 forskellige gasser. Opdag hvad der får nogle balloner til at svæve og andre til at synke.
Læringsmål
- Bestemme hvad der forårsager at varmluftsballonen, atmosfærisk luft- og heliumballonen stiger op eller synker ned i kassen.
- Forudsige hvordan en ændring blandt variablerne P, V, T, og nummer, påvirker bevægelsen af ballonerne.
