Understanding Ecosystems and Population Dynamics

Miss Fati introduces a science lesson on populations and resources, focusing on marine ecology and the study of jellies. Dr. Kelly Robinson, a marine ecologist, shares insights into her work with jelly populations and their ecological roles. The lesson emphasizes understanding ecosystems and population dynamics, encouraging students to explore these concepts through a digital model. Students are guided to think critically about the factors affecting jelly populations and are encouraged to collaborate and share ideas.

What materials are recommended for the lesson on populations and resources?

• A calculator and ruler

• A pencil or pen and some paper

• A textbook and highlighter

• A laptop and headphones

What is the primary focus of Dr. Kelly Robinson's research?

• The breeding habits of sea turtles

• The study of jellies

• The migration of whales

• The behavior of dolphins

Why is it important to study changes in jelly populations?

• To create better aquariums

• To develop new medicines

• To understand their role in ecosystems

• To improve fishing techniques

What is an ecosystem?

• A large body of water with marine life

• A collection of different species of plants

• All living and non-living things in an area

• A group of similar organisms living together

What has been observed about the moon jelly populations in the Arctic Ocean?

• They have remained stable

• They are increasing dramatically

• They are decreasing rapidly

• They have migrated to warmer waters

What is the purpose of using a digital model in the study of ecosystems?

• To visualize population interactions

• To track ocean currents

• To simulate weather patterns

• To map the seafloor

What can you do with the digital model's food web overlay feature?

• Identify new species

• Predict future population sizes

• See interactions between organisms

• Measure water temperature

What behavior was observed in the digital model regarding the green leaves?

• They changed color

• They reproduced on their own

• They moved around frequently

• They hunted other organisms

What was a common observation about the organisms in the digital model?

• They all stayed in one place

• They were all predators

• They were constantly being born and dying

• They only interacted with plants

What is the next step in the investigation of moon jelly populations?

• Writing a report on jellyfish behavior

• Developing a new digital model

• Playing a game to understand births and deaths

• Conducting field research in the Arctic
