Energy Storage and Ecosystem Challenges

The video introduces the final unit of seventh-grade science, focusing on matter and energy in ecosystems. It discusses Biosphere 2, an experiment to create a closed system for sustainable living, highlighting the challenges faced and lessons learned. The video then introduces a mission to investigate a biodome where organisms are failing, encouraging students to explore why plants and animals lack energy storage molecules.

What materials are recommended for students to have during the lesson on matter and energy in ecosystems?

• A calculator and a ruler

• A piece of paper and a pencil or pen

• A textbook and a highlighter

• A laptop and headphones

What was the primary goal of Biosphere 2?

• To develop new agricultural techniques

• To test if humans can live in a closed ecological system

• To create a new type of plant species

• To study the effects of pollution on ecosystems

Which of the following was NOT a biome included in Biosphere 2?

• Mangrove marsh

• Tropical rainforest

• Arctic tundra

• Savanna

What was one of the main challenges faced by the crew in Biosphere 2?

• Overpopulation of animals

• Insufficient food production

• Too much rainfall

• Lack of sunlight

What was a significant outcome of the Biosphere 2 experiment?

• It proved that humans can easily replicate Earth's ecosystems

• It highlighted the difficulty of replicating Earth's natural processes

• It led to the discovery of a new plant species

• It resulted in a new method of water purification

What is the main focus of the biodome investigation mission?

• To study the effects of climate change on ecosystems

• To build a new biodome

• To create a new type of energy storage molecule

• To find out why organisms in the biodome are not thriving

What did the Eco nots notice about the organisms in the biodome?

• They were getting sick and failing to reproduce

• They were migrating to other areas

• They were thriving and reproducing rapidly

• They were evolving into new species

What is an energy storage molecule?

• A molecule that stores water

• A molecule that organisms use to release energy

• A molecule that captures sunlight

• A molecule that stores carbon dioxide

Why is it important for organisms to have enough energy storage molecules?

• To survive and be healthy

• To migrate to new areas

• To maintain their body temperature

• To change their color

What is the big question the students are trying to answer in the biodome investigation?

• Why didn't the plants and animals in the biodome have enough energy storage molecules?

• Why is the biodome not producing enough oxygen?

• Why is the temperature in the biodome too high?

• Why are the plants in the biodome growing too fast?
