The slope of the land and the materials under ground must be considered when planning how to build on the land in a community to lessen landslide risk. Changing the slope of the land (or even the amount of vegetation on a slope) can have dangerous consequences. This activity will introduce you into thinking critically about the land in your area!
In 1972, NASA launched a special satellite called Landsat that contained a new camera designed to take pictures of the Earth. Why was this satellite so incredible? Well, it could take a series of pictures of almost the entire Earth over and over again, season after season, month after month, year after year. You will be seeing Landsat images in this activity and learn how to interpret them.
Nitrogen is an element that is found both in living things and the nonliving parts of the Earth system. In this classroom activity, students play the role of nitrogen atoms traveling through the nitrogen cycle to gain understanding of the varied pathways through the cycle and how nitrogen is relevant to living things.
People interact with Earth’s water (hydrosphere) in a variety of ways. We depend upon water for survival, but we also need it to keep clean and help avoid spreading disease. On our ever-changing Earth, the supply of fresh water can be limited for some humans. We need good techniques to make the best use of the fresh water we do have.
For example, when you wash your hands, how do you do it? With soap and water? With water alone? Do you scrub your hands or simply rinse them under the faucet? Does it even matter? Yes, it does!
Landslides not only are dangerous — causing on average more than 25 deaths and over $1 billion in damages a year — but are also widespread, occurring in all 50 states. Compounding the hazards, these natural disasters often occur along with other similar natural phenomena, such as floods or earthquakes.
To minimize risk, the slope of land and materials underground must be considered when planning how to build in a community. Altering the slope of land, or even the amount of vegetation on a slope, can have dangerous consequences.
Each group will design a water filtration system and present to the class, why they picked their design.
Water on earth is used over and over. The water cycle, the continuous movement of water from ocean to air and land then back to the ocean in a cyclic pattern, is a central concept in meteorology.
Water moves from Earth’s surface to the atmosphere and then returns to the surface. This process is nearly always depicted in water cycle diagrams by arrows drawn in a circular direction.
However, the actual path water may take in its cycle is far more complicated. In this activity, you will discover multiple cycles by acting as water molecules and traveling through parts of the overall water cycle. In the end, your water cycle will look nothing like the conceptual model but will represent a more realistic cycle.
Learn to identify fire risk factors for a property located near a wildland area.
Climate scientists around the world study greenhouse gases and the ways they affect global climate. By making your own small greenhouse in this activity, you can recreate the greenhouse effect and measure its effect on temperature.
