Population Dynamics and Stability Concepts

In this lesson, Miss Fati continues the series on populations and resources, focusing on the moon jelly population increase. Students are encouraged to gather materials and play a population game to understand the effects of births and deaths on population size. The lesson includes student ideas on population changes, data analysis, and graphing. A visual analogy of a liquid tank is used to explain stability in systems, illustrating how populations can remain stable even with ongoing births and deaths.

What materials are suggested for the lesson on moon jelly populations?

• A textbook and highlighter

• A calculator and graph paper

• A pencil or pen, paper, and packet pages

• A computer and internet connection

What is one idea students had about the increase in moon jelly populations?

• Moon jellies are evolving to live longer.

• Moon jellies are clustering for defense, reducing deaths.

• Moon jellies are migrating to warmer waters.

• Moon jellies are being fed by humans.

What is needed to play the population game?

• A board game and cards

• Two dice and small tokens

• A computer and software

• A stopwatch and whistle

In the population game, what do odd numbers on the dice represent?

• Migration

• Births

• Stability

• Deaths

What was observed when there were more births than deaths in the game?

• The population decreased

• The population became extinct

• The population remained stable

• The population increased

What does the term 'stability' refer to in population studies?

• A population that is constantly growing

• A population that fluctuates wildly

• A population that remains the same over time

• A population that is decreasing

What analogy is used to explain stable systems?

• Liquid being added and removed from a tank

• A river flowing into the sea

• A bird building a nest

• A tree growing in a forest

What happens to a system when more is added than removed?

• The system becomes chaotic

• The system increases

• The system decreases

• The system remains stable

How can a population remain stable even with births and deaths occurring?

• By having no births or deaths

• By having equal numbers of births and deaths

• By having more births than deaths

• By having more deaths than births

What will be explored in the next lesson regarding moon jelly populations?

• The migration patterns of moon jellies

• The habitat preferences of moon jellies

• The diet of moon jellies

• The birth and death rates of moon jellies
