The sun rises in the east and sets in the west. This we know from personal observation. But have you ever thought about where the sun is in the sky at the same time each day?
You might think the sun would appear at the same place at the same time each day. This would be true if Earth had no tilt and its orbit were a perfect circle. But this is not the case.
In this investigation, you'll have the opportunity to learn about the many geological features in our country's national parks. You might not realize this, but a large number of the national parks were created because of their amazing geology. Just think of the geological features of Yellowstone National Park, the Grand Canyon, Hawaii Volcanoes National Park, and many more!
Maps are two-dimensional ways of representing information about the natural and built world from a "top-down" perspective. You are probably familiar with road maps that show where roads go and which roads intersect with others and where. You also may have seen weather maps, which show weather patterns across a specific geographic area, or political maps, which show where borders are for countries and areas within those countries.
A refuge is a place where you can record observations of seasonal changes to plants, trees, and wildlife. You can use GPS (global positioning system) data to mark an observation spot and record your observations. Then, if you can, visit the same national wildlife refuge during other seasons in the year to document changes in the natural world.
This investigation will help you to learn that different geologic materials have different characteristics.
Learn the characteristics of difference kinds of minerals in this hands on investigative activity.
A normal fault occurs when rocks break and move because they are being pulled apart. As the area is stretched, the rocks move along the fault. Each movement causes an earthquake. This model demonstrates how a block of rock is extended by a normal fault.
Groundwater is contained in the zone of saturation below the land surface. The top of this zone is known as the water table. People can tap into this source of water by drilling wells. The depth of the well and level of the water table greatly influences the wells productivity. In this activity you will demonstrate the relationship of groundwater to wells.
An earthquake occurs when massive rock layers slide past each other. This motion makes enormous vibrations, which travel from the site of the earthquake in waves. In this activity, you will model how earthquakes move in three dimensions.
In this activity, students will learn the pattern of major ocean currents and how they are changed by wind, land and water.
