Google Expeditions - Hydrosphere

Publisher

Google Expeditions/Vida Systems

Standard

5-ESS2-1 Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.

Description

The word hydrosphere comes from the Greek words for “water” and “ball.” It is the term used to talk about all of the water on our planet Earth.

Questions

*3 guiding questions for students to explore

Question 1 - Why is it important to be careful with our freshwater resources?

  • Only 0.007% of the Earth’s water is suitable for human use. This tiny amount is shared with people, plants, and animals.

Question 2 - How does rain occur?

  • As water vapor rises, it starts to cool, which makes the water molecules get closer together. As more water vapor arrives via wind and evaporation, a cloud starts to form. Once the cloud is formed and the water vapor continues to condense, water droplets begin to form. Teh water droplets become too heavy to remain in the air and they fall as rain.  

Question 3 - Why are oil spills a problem?

  • Oil floats on top of water forming a barrier which prevents sunlight and oxygen from getting through. Phytoplankton die (the basis for many food chains), animals suffocate, and animals that get coated with oil can no longer regulate their body temperature to keep warm.

Conservation International Film: Valen’s Reef

Publisher

Google Expeditions/Conservation International

Standard

5-ESS 3-1 - Obtain and combine information about ways individual communities use science ideas to protect the Earth’s resources and environment.

Description

Conservation International’s film, “Valen’s Reef,” will take you to The Bird’s Head Seascape in Raja Ampat, in Indonesia’s West Papua province. This region — the epicenter of the world’s marine biodiversity — is a source of immeasurable value for the communities that rely on its ecosystems for food, livelihoods and protection from rising seas and storms. For decades, the abundant natural resources of the Bird’s Head Seascape were a major target for development and exploitation, leading to destructive fishing practices that wiped out fish stocks and degraded the coral reefs.

Questions

*3 guiding questions for students to explore

Question 1 - Why is it important to save the coral reef?

  • Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet. They protect coastlines from the damaging effects of wave action and tropical storms. provide habitats and shelter for many marine organisms.

Question 2 - What are the next steps for Bird’s Head?

  • The local community now needs to take over in the conservation efforts. This project will act as a model of community managed protected marine areas around the world.

Question 3 - What was the human impact on this coral reef?

  • Fishermen used dynamite to kill the fish (blast fishing) which lead to the destruction of the coral reef.

Ecosystems of Borneo

Publisher

Google Expeditions/Alchemy VR

Standard

5-LS2-1 - Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.

Description

Within the tropical region of Borneo, there are various different and distinct ecosystems that are subject to very different ecological and climatic conditions. Each have their own complement of animals and plants that have evolved to be well adapted to these conditions. We start our expedition in Bako national park. Bako contains almost every type of plant life found in Borneo, with over 25 distinct types of vegetation. With an area of just 27 km squared, you would think there to be little space for variation. And yet, within that small space you can find, tropical rainforest, mangrove swamps, dry heathland and many more ecosystems that support vastly different forms of life. We will explore a few of them in Bako, as well as elsewhere in mainland Borneo.

Questions

*3 guiding questions for students to explore

Question 1 - Why are the plants special that grow on the cliffs?

  • They are adapted to grow in a sandy soil and have to withstand high winds and high concentrations of salt.

Question 2 - How does the forest floor contribute to the ecosystem?

  • The forest floor contains leaf litter, which is host to microorganisms like fungi. This fungi not only acts as a decomposer, but also attracts flies, which further contributes to the breakdown of organisms.

Question 3 - Compare and contrast a stream and river ecosystem.

  • (Answers will vary) The stream ecosystem supports moss, which benefits organisms that survive in humid conditions. The tropical climate can contain more than 15,000 species. This river ecosystem has a dry and rainy season. This creates different water levels. The water levels create different nutrient levels in the soil at different times of the year.
