Take a trip to Earth’s freezer – the coldest, windiest, driest, place on Earth. How long has Antarctica been like it is today? That’s what polar researchers want to find out. Meet ANDRILL, the Antarctic drilling team in this video.
Paleo Sleuths - What's In the Box?
This is an introductory inquiry activity where students carry out investigations, record data, and ask questions to build relationships between evidence and explanations. This activity can be used to build background knowledge about science and engineering investigative processes.
Water is becoming scarce and the demand of irrigation to increase crop yields in the Midwest is taxing one of the largest sources of ground water, the High Plains Aquifer. States such as Kansas now look to alternative agriculture to help address the dwindling water supply. Nebraska ranks first in the nation for irrigated acres from groundwater. Agriculture accounts for 70% of the ground water consumption. This raises the concern of how long can the ground water supply sustain the demand from agriculture and communities?
What is an Aquifer?
Aquifers are bodies of saturated rock and sediment through which water can move, and they provide 99% of our groundwater. Humans rely on aquifers for most of our drinking water. However, we are not only depleting this supply but are its biggest polluters as well. This infographic provides facts and illustrations to explain the process.
The Cost of Water!
This slideshow visually compares the costs of bottled water to tap water. The up-front bottle costs run high, but the post-costs to the environment are even more expensive.
The Groundwater Term Game
This Groundwater Game tests your knowledge of major terms used to describe parts of the aquifer systems, from groundwater to permeability to saturated zone. Drag and drop the correct term into a sentence to make it accurate and to match the illustration. Can you score 12 out of 12?
Groundwater Beneath the Surface
This lighthearted animation takes us beneath the surface to see groundwater in action. Watch anthropomorphized drops of groundwater travel through this system. A smiling character with a shovel digs us down to the water table, allowing us to flow through the water cycle and thus making the process much easier to understand.
Paleo Sleuths - Creating Fossil Field Jackets
Students, as preparators, will make a fossil field jacket using a seashell fossil. Seashells are used because they are larger to manage for this activity and can be ordered in a larger quantity. Other fossils or rocks can be used depending on the size. Palm size is recommended. They will only cover the topside of the seashell fossil or other fossil in this activity.
