An introduction to the Wright brothers, the process of innovation and the concepts of flight.

Explore composites in this fast-paced webcast to learn what they are, how they are made and how they are used in the aerospace industry

Simple machines can be found almost anywhere. Once you know what to look for you will be surprised at how many simple machines you use in your daily life.

Astronomer Carl Sagan discusses the possibility of time travel in this audio-enhanced interview from the NOVAWeb site.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

This animation adapted from NASA shows the orbital paths of spacecraft in NASA's Earth Observing Fleet that are a source of wide-scale, primary research about Earth.

This seminar is intended to help students in the MIT/Woods Hole Oceanographic Institution Joint Program develop a broader perspective on their thesis research by considering some aspects of science in the large. The first part of the course challenges students to develop a thoughtful view towards major questions in science that can be incorporated in their own research process, and that will help them articulate research findings. The second part of the course emphasizes science as a social process and the important roles of written and oral communication.
This course is offered through The MIT/WHOI Joint Program. The MIT/WHOI Joint Program is one of the premier marine science graduate programs in the world. It draws on the complementary strengths and approaches of two great institutions: the Massachusetts Institute of Technology (MIT) and the Woods Hole Oceanographic Institution (WHOI).

Part One of this video lesson will explore the science that explains soap bubbles, as well as the application of this knowledge to other areas, such as architecture and biology. We first introduce the concept of surface tension. In Part Two of this video lesson, students will learn where the colors of soap bubbles come from and also learn what soap bubbles and telescopes have in common. The students will first make a connection between light and waves waves and will then go on to explore various characteristics of waves through a series of classroom activities.

In this activity you'll see how the sun's tilt on its axis changes the length of shadows. For example, why is your shadow longer in winter than in summer? It's easy to see the answer if you have a "sun" and an orbiting "earth" to demonstrate. Like many other ancient people, the ancient Chacoans used the annual changes in shadows to measure the passage of time and the change in seasons. You can too!

This laboratory activity demonstrates how seismic waves are generated and helps students understand how they can reveal the composition of Earth's inner layers. Students will construct models by filling shoe boxes with various materials, drop rocks on them to generate 'seismic waves', record the waves, and make observations about their differences.

Students learn about STEM education through an engineering design challenge that focuses on improving building materials used in shantytowns. First, they consider the factors that lead to shantytown development. After researching the implications of living in shantytowns, students design, build and test cement-based concrete block composites made of discarded and/or recycled materials. The aim is to make a material that is resistant to degradation by chemicals or climate, can withstand natural disasters, and endure through human-made conditions (such as urban overcrowding or pollution). The composites must be made of materials that are inexpensive and readily available so that they are viable alternative in shantytown communities. Students assess the results both chemically and physically and then iterate their designs with the materials that proved to be strongest.

In this decision-making exercise, students investigate what would occur if a dam were built along Nanticoke Creek, a real stream just north of West Corners near the Village of Endicott, New York. They will use topographic maps to determine how much area would be flooded by the new reservoir, to study river drainages, and to consider the impacts of dams on a region. They must also consider rivers in the context of their relation to humankind. The exercise can be extended to other, more local locations having similar topography.

In this adapted ZOOM video segment, cast members calculate how much water they each use during a typical shower. They compare their results to their original predictions.

In this activity, students investigate convection as it applies to Earth processes. They will assemble a model using a bread pan to view convection in two paired cells. They will also investigate the strengths and weaknesses of the model thay have constructed and answer some questions about what they are seeing.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts. Escapements are found in mechanical clocks, such as those driven by a pendulum or a spring. Learners will build the wrapping form of escapement said to be used in a fifteenth-century German clock.

This video segment from IdahoPTV's D4K lists, describes and shows examples of the 6 simple machines and how they make work easier.

Students will prepare the vegetable beds for planting exploring how simple and compound machines work.

In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action. This lesson guide provides one of many ways to build the spinner and links to other methods.
