Herbivory and Plant Interspecific Competition

This model simulates plant interspecific competition and herbivory. Students may investigate two herbivory relationships and an interspecific competition relationship between two plant species.

Grades: 6-8
NGSS Standards: MS-LS2-2

Community interaction-Mutually beneficial

This model simulates the interaction of mutually beneficial between bees and sunflowers.

Grades: 6-8
NGSS Standards: MS-LS2-2

Community Interaction Game

Play this game to identify interaction among six mysterious species.

Grades: 6-8
NGSS Standards: MS-LS2-2

Run the model

Bark Beetle Outbreaks

Explore forest dynamics resulting from the interaction among bark beetle, spruce forest, temperature, drought severity, and tree diversity.

Grades: 6-8
NGSS Standards: MS-LS2-1, MS-LS2-4.

Teacher notes

Run the model

Climate-driven Bark Beetle Outbreaks

This model simulates climate-driven bark beetle outbreaks. Compared to the basic "Bark Beetle Outbreaks" model above, this model separates the effects of rising temperatures on beetle reproduction and survival. This model also allows students to explore the impacts of sanitation cutting and salvage cutting.

Grades: 6-12
NGSS Standards: MS-LS2-1, MS-LS2-4,MS-LS2-5; HS-LS2-1; HS-LS2-2; HS-LS2-7

Carrying Capacity

Explore carrying capacity in a hypothetical elk population. You may explore how carrying capacity is influenced by four types of factors: food, predators, other herbivores, and temperature.

Grades: 6-12;
NGSS Standards: HS-LS2-1

Run the model

Brine Shrimps in Great Salt Lake

A real-world example of carrying capacity. Explore the brine shrimp population dynamics in the south arm of the Great Salt Lake resulting from the lake salinity changes, which are affected by stream inflow, north arm water inflow, and evaporation.

Grades: 6-12;
NGSS Standards: MS-LS2-1, HS-LS2-1
