Interaction Among Organisms

What better way to learn than to recreate the experiments of famous scientists in a virtual laboratory! Perform experiments, make predictions, analyze data, and draw conclusions. With interactive science activities on your device, endless learning opportunties are right at your fingertips.

Head to the outback of Australia to witness its rabbit-proof fence, a structure built in the 1900s to alleviate competition between rabbits and indigenous species. Then perform various experiments with paramecia to learn about interspecific and intraspecific competition.

• Learn why organisms compete.
• Recreate the famous experiments of scientist Georgy Gause.
• Experiment with the growth of a single paramecium species to discover intraspecific competition.
• Explore the growth of two paramecium species in a growth medium with limited resources.
• Discover evidence of resource partitioning.
• Learn about the competitive exclusion principle.

App features:
