The JOIDES Resolution is an amazing ship that contains all the equipment necessary to drill into the ocean floor for samples of rock and sediment: a derrick, drill pipe, drilling tools, and drill bits. Once the cylindrical core sample arrives on the rig floor, the drill crew passes the 10 m core to technicians. They, in turn, carry it to the catwalk, where it is cut into 1.5 m sections and labeled. After the core is brought up on deck, the technicians notify the rest of the crew by yelling: "CORE ON DECK!"
To allow students to produce a "marketable" product made from minerals that are used by most people every day. Both the abrasive and cleansing compounds found in toothpaste, calcium carbonate and sodium bicarbonate, are minerals.
Crushed stone, sand, and gravel are the three kinds of rock fragments that are called aggregates. Consider: At the current rate of usage, every American will need 1.37 million pounds of aggregates in his or her lifetime. Aggregates are mined in every state in the nation. Aggregates are the most commonly used mined rocks in all countries of the world.
In this activity you will use seeds to model mining valuable materials from rocks.
How much precipitation falls in your area? To find out, use the instructions below to create your own rain gauge. Then head outside to measure rainfall in your neighborhood.
Atmospheric scientists study weather processes, the global dynamics of climate, solar radiation and its effects, and the role of atmospheric chemistry in ozone depletion, climate change, and pollution. They observe what's going on in our atmosphere today and compare it to records from years past. To monitor the weather, atmospheric scientists use highly specialized instruments that measure rainfall, wind speed and direction, humidity, and atmospheric pressure. You can measure these at your home or school. Begin creating a weather station by building a psychrometer, also called a hygrometer, to measure the relative humidity.
Students will become familiar with fire terminology, realize how fire can be used as a management tool, and better understand the factors that need to be considered when planning a prescribed burn.
We find carbon everywhere on Earth ─ in trees, rocks, fossil fuels, oceans, and even you! Carbon doesn’t stay in one place, through. Scientists study how carbon moves from one place to another. This is the carbon cycle.
Learn the value and importance of the The Wilderness Act of 1964 with this online activity from the U.S. Fish and Wildlife Service.
Why is CO2 increasing in the atmosphere? Who is doing it? Many people think that CO2 is “pollution,” so that clean burning should be a way to eliminate greenhouse gas emissions. In this demonstration, we review basic chemistry (see illustration) to realize that producing CO2 is an inevitable product of burning any fossil fuel.
