It's easy to imagine what it's like to be a doctor, lawyer, or teacher. However, the day-to-day life of a shellfish and wetland ecologist can be a little more difficult to understand. Help your students find out what an ecologist does by hearing from Danielle Kreeger. She's the science director for a group that works to protect and improve the Delaware River and Bay. Listen to hear more about her career as an ecologist.
As nations look for clean energy alternatives many are turning to wind and solar, but Indonesia is turning to its volcanoes. Indonesia has 130 active volcanoes. These volcanoes generate geothermal heat that is releases through vents and hot springs throughout the country. Power companies are learning to harness and redirect this heated steam into power plants in order to generate electricity. Indonesia’s geothermal energy potential is huge, but start up costs and oil subsidies might prevent this burgeoning clean energy from taking off.
Tsunamis are created by tectonic plates thrusting against each other and then lifting the sea floor and dropping it down, which creates a giant wave. A 2010 earthquake in Chile was caused by a shift in the seafloor. This same shift set off tsunami detection buoys and left scientists waiting for the tsunami to hit. But it ended up being small. Listen to learn more about this quake and how tsunamis are created.
As plants and animals reproduce over time, they are able to change and adapt to ensure or improve their chances of survival. The evolutionary goal of reproduction is paired with the concept of natural selection and survival of the fittest to determine who will reproduce. From colorful plumage to size, different species use different strategies to ensure reproduction and mate selection. The sand tiger shark has a unique strategy to ensure successful reproduction - and it depends on the timing of mating. Listen to learn more about the ultimate sibling rivalry while in the womb.
In 2014, astronomers discovered a new dwarf planet on the edge of our solar system. This discovery has changed scientists’ understanding of what exists in the solar system beyond the more well known dwarf planet, Pluto. The new planet is a pink ball of ice, and scientists believe there could be an unseen and undiscovered planet larger than Earth in the far reaches of our solar system.
