Learn about the wildebeest and locusts on the move in this video segment from Nature.

This animation from KET's distance learning physics course demonstrates the mathematical formula for a scientific law as it applies to light.

Current research on the evolution and development of cognition and affect, including intuitive physics, biology, and psychology, language, emotions, sexuality, and social relations.

How does the temperature of soybean oil affect the viscosity of the oil? In this lesson, students will determine the viscosity of soybean oil (vegetable oil) at different temperatures. They will use thermometers and the viscosity chart. 

For Iowa History- Unit 3 PPT Learn about the First Europeans on Iowa Land-Fur Trade & Tribal Movements 1600-1800• Video narrative written by Sandra Kessle...

The purpose of the resource is to develop hypotheses about which environmental factors are most important to plants.

STUDENT ACTIVITY - 3rd - GA/TXThis is a distance-learning lesson students can complete at home.Students will explore the outdoors for examples of different plant structures and determine how plants use these structures to meet their needs.This activity was created by Out Teach (out-teach.org), a nonprofit providing outdoor experiential learning to transform Science education for students in under-served communities.

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying. When we tried this trick on the Exploratorium's exhibit floor, we gathered a crowd of visitors who wanted to know what we were doing. We explained that we were engaged in serious scientific experimentation related to energy transfer. Some of them may have believed us. If you'd like to go into the physical calculations of this phenomenam, see the related resource "Bouncing Balls" - it's the same activity but with the math explained.

This lesson introduces the concepts of longitudinal and transverse waves. Students see several demonstrations of waves and characterize them by transverse and longitudinal behavior. This lesson also introduces the Sunken Treasure theme of the Sound and Light unit a continuous story line throughout the lessons.

In this activity, students play the game Simon Says to make the amplitudes and wavelengths defined by the teacher. First they play alone, and then they play with a partner using a piece of rope.

Students learn the decibel reading of various noises and why high-level readings damage hearing. Sound types and decibel readings are written on sheets of paper, and students arrange the sounds from the lowest to highest decibel levels. If available, a decibel meter can be used to measure sounds by students.

This introductory lesson presents an overview of the applications associated with the oxy-fuel welding and cutting processes.  Learners will be exposed to the equipment associated with the process as well as the fundamentals and applications necessary to accurately weld and cut using the process. This lesson should only be used if the instructor has previous experience in oxy-fuel welding.  The instructor must add additional safety protocols associated with the manufacturers of the equipment and school guidelines.

STEM in 30 celebrates the 2017 Great American Eclipse live from Liberty, Missouri, in the path of totality, and at the Phoebe Waterman Haas Public Observatory at the Museum in Washington, DC.

This lesson guides a student inquiry into properties of the ocean's carbonate buffer system, and how changes in atmospheric carbon dioxide levels may affect ocean pH and biological organisms that depend on calcification.

SSAC Physical Volcanology module. Students build a spreadsheet and apply the ideal gas law to model the velocity of a bubble rising in a viscous magma.

This activity focuses on getting the students to think about disabilities and how they can make some aspects of life more difficult. The students are asked to pick a disability and design a new kind of sport for it.

Join the Astronomy Education team as they discuss this amazing image, what a black hole is, and how the National Science Foundation and the Event Horizon Telescope accomplished this amazing feat.

A conversation with New Horizons principal investigator Alan Stern and astrobiologist David Grinspoon about their new book, Chasing New Horizons: Inside the Epic First Mission to Pluto.

This online video gallery is from the Museum's Seminars on Science, a series of distance-learning courses designed to help educators meet the new national science standards. What Is Space?, part of the Frontiers in Physical Science seminar, is available in broadband and modem formats and with a printable PDF transcript. The video explains how Einstein's General Theory of Relativity changed the way we look at space.

Students will discover the carbon component in soils, the role carbon plays in soil health, and the role that regenerative agriculture practices play in soil health and climate change.
