Measure for Measure

Geoscientists use special boats to conduct research at sea. One of these boats is named the JOIDES Resolution (JR). Unlike most oceangoing vessels, the JR has a flat bottom, a 6.4-meter hole in the middle, 12 laboratories, and a derrick towering 67 meters above the waterline! Why? So scientists can sail nearly anywhere in the world to drill for samples of rocks and sediment from below the seafloor. What for? In hopes of discovering clues about Earth's history and structure, life in the deep biosphere, past climate change, earthquakes and natural resources.

Measuring Glacial Retreat

The USGS has been studying glaciers in Glacier National Park since 1850. It is estimated that there were 150 glaciers in the park back then, and when the national park was established in 1910. Today only 25 glaciers remain.

 Scientists go back every year to repeat photographs, as well as to examine the ice and the ecology of the landscape to see how glacial retreat is affecting plant and animal species that live there.

Mineral Electrical Conductivity

People must mine minerals to provide all kinds of materials that we depend on in our lives. The purpose of this activity is to test the conductivity of various minerals with a simple electrical circuit and draw conclusions about which ones would be used in electronics.

Mineral Identification

Learn the characteristics of difference kinds of minerals in this hands on investigative activity.

Model of a Normal Fault

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.

Modeling an Oil Reserve

Abundant oil and natural gas form only where conditions in the Earth are just right. Doing this investigation will help you understand how geoscientists identify and explore petroleum-rich reserves.

Modeling Earthquake Waves

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.

Modeling Oil and Gas Reservoirs

This activity will help you to understand some of the factors that petroleum geologists need to consider when deciding where to recommend drilling for oil. Since people use petroleum products for energy and as source materials for petrochemicals, it is important as citizen scientists to understand the science and technology behind the search for oil and natural gas.

Monitoring Life in the Rocky Intertidal Ecosystem

The five national marine sanctuaries along the West Coast monitor the health of the rocky intertidal ecosystem. One way of doing this is to collect data on the relative abundance of the organisms living in that ecosystem. Since this is such a big task, the national marine sanctuaries are training students in how to follow standardized protocols to help with the monitoring. The information collected is added to an online database that the sanctuaries use to collect baseline data and track long-term changes in the environment. This activity will allow you to learn the sampling techniques used in the field by these citizen scientists who participate in LiMPETS.
