Amazing Space: Planetary Nebula NGC 2440 Lithograph
No full textThis lithograph contains a Hubble Space Telescope image that shows the colorful Planetary Nebula NGC 2440 with one of the hottest known white dwarfs at its center. The text briefly explains the process of stellar death of sun-like stars and those with a mass greater than eight times the Sun. The accompanying classroom activity is a curriculum support tool designed for use as an introductory inquiry activity. It can be incorporated into a unit that has a scientific inquiry and/or stellar evolution theme. During the classroom activity, In Search of... Stellar Death, students use the lithograph images and text to generate questions about the planetary nebula NGC 2440 and how stars end their lives. Students conduct research to answer their questions then compare the endpoints of different mass stars, providing supporting evidence from their research.

Sampling the Sun: What are We Made Of? The Sun, the Earth, and You
No full textThis hands-on activity aims to help students understand that elements are the basic building blocks of all things found on Earth and in space including water, the human body, and the Earth, the Sun, and the planets. By counting elements extracted from a simulated sample, students will learn how the extraction of atoms from the Genesis samples help scientists have a better understanding of the abundance of elements from the solar wind. The experience helps students to discover that the elemental abundance from the Sun can be used as a baseline to compare with the diverse bodies of our Solar System. Educational levels: Intermediate elementary, Middle school
An Introduction to Ensemble Streamflow Prediction
No full textThis module provides basic information on probabilistic streamflow forecasting. In this webcast, Dr. Richard Koehler, the National Hydrologic Sciences Training Coordinator for NOAA's NWS, presents information about the types of organizations that might use probabilistic streamflow forecasts as well as foundation concepts and background for ESP methods. The module begins with a brief review of hydrologic models including deterministic, stochastic, and scenario-based approaches. It then provides an overview of time-series approaches including a summary of traditional techniques such as flood frequency, flood analysis, statistical analysis, and trend analysis. Finally, the module presents the basics of ESP techniques including an explanation of its strengths, weaknesses, and appropriate application. The module also provides guidance on how to interpret ensemble forecast products. Educational levels: Graduate or professional
