Students will construct CD hovercraft and apply Newton's laws of motion to make them work. They will also investigate how hovercraft reduce friction; learn how the technology is used in training astronauts for space missions; and design their own hovercraft competitions.
This is an activity about a very important ingredient in most baked goods - gluten! Why is gluten so important? Without it, there would be nothing to hold the gas that makes bread rise. Learners will experiment with different types of flour to get a feel for gluten, and discover why using different flours can lead to such different results in the kitchen.
Logarithms are very handy when dealing with numbers at different scales but they are also useful helping us average measurements of physical phenomena that have nonlinear behavior. In this example, students learn about cloud albedo and calculating cloud optical depth. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Our standard of living depends on the pace of economic growth. That pace can be enhanced through increased productivity brought about by investment in physical and human capital and advances in technology. In this course, students will learn about these tools to increase productivity and advance our standard of living.
Look inside a battery to see how it works. Select the battery voltage and little stick figures move charges from one end of the battery to the other. A voltmeter tells you the resulting battery voltage.
This course provides students with a scientific foundation of anthropogenic climate change and an introduction to climate models. It focuses on fundamental physical processes that shape climate (e.g. solar variability, orbital mechanics, greenhouse gases, atmospheric and oceanic circulation, and volcanic and soil aerosols) and on evidence for past and present climate change. During the course they discuss material consequences of climate change, including sea level change, variations in precipitation, vegetation, storminess, and the incidence of disease. This course also examines the science behind mitigation and adaptation proposals.

In this lesson, students learn about sound. Girls and boys are introduced to the concept of frequency and how it applies to musical sounds.
Introduction to the history of Rapa Nui and Polynesia (~7,300 words) for middle and high school students.
In this unit, students examine the interaction between the hydrologic cycle and rock cycle through exploring the processes of weathering, erosion, transport and deposition of sediments both in real stream systems and in a physical, table-top model of a stream. This activity focuses group thinking on: 1) identification and interpretation of patterns that define physical characteristics associated with three distinct areas of a river system and 2) the type of energy transfers that occur as sediments are eroded, transported and deposited.

This course will begin with brief overview of what important current research topics are in oceanography (physical, geological, and biological) and how acoustics can be used as a tool to address them. Three typical examples are climate, bottom geology, and marine mammal behavior. Will then address the acoustic inverse problem, reviewing inverse methods (linear and nonlinear) and the combination of acoustical methods with other measurements as an integrated system. Last part of course will concentrate on specific case studies, taken from current research journals. This course is taught on campus at MIT and with simultaneous video at Woods Hole Oceanographic Institution.
Readers will learn about the nature of health, health education, health promotion and related concepts. This will help to understand the social, psychological and physical components of health.

In this exercise, sudents write a series of three stories that explain and/or illustrate rock-forming processes. As an alternative, they may write a single story that addresses the rock cycle. Describing these processes at a level appropriate for their target audience (second graders) requires an adequate understanding of the geologic processes involved and can reveal problems or misconceptions in the students' ideas of how rocks are formed. Teacher's notes and rubrics for teacher and peer review are provided.
This OLogy activity uses the traditional Japanese art of paper-folding to help kids understand dimensions. The activity begins with a brief introduction to both dimensions and origami. The kids are then given instructions, included as printable PDFs, for morphing 2D paper into 3D models (a simple box and a water bomb).The activity ends with an illustrated look at dimensions, from the zero dimensions of a point to the fourth dimension of time.
30-page illustrated guide to fundamentals of measurement. This is intended to be a clear, comprehensive overview of effective measurement technique. Intended for advanced high school or introductory college level students. Includes worked examples and problems.
This is a hands-on lab activity about the water cycle, specifically evaporation and condensation. Using materials such as clay, ice and a lamp, learners will observe the relationship between temperature and condensation and temperature and evaporation. They will then draw a diagram or a concept map of the water cycle. Background information, common preconceptions, a glossary and more is included. This activity is part of the Aquarius Hands-on Laboratory Activities.
The Integrated Data Viewer (IDV) is a software framework for analyzing and visualizing geoscience data sets collected by the Unidata Program. The IDV may be used to display and analyze satellite imagery, gridded data, surface observations, balloon soundings, radar data and more. Most of the data are provided in real time or near-real time. The IDV can display data anywhere on the globe with a wide selection of map projections and map backgrounds including a 3D spherical globe. Over 20 kinds of 2D and 3D data displays allow users to create cross-sections, profiles, animations and value read-outs of multi-dimensional data sets. A useful feature of the site is the ability to save displays in "bundle" files for use in classroom and lab exercises. Thorough and easy-to-follow directions for IDV installation and use are provided and annual training workshops are offered by Unidata. The data viewer is available for a free download, and data sets are available to participants who are affiliated with a degree-granting institution or a non-profit institution with an education and/or research mission. This resource is part of the Using Data collection. http://serc.carleton.edu/usingdata/
In this lesson, students learn about some of the early explorations of the Northwest Passage, and how the changing sea ice extent has prompted new explorations of this region to transport goods from one region of the Northern Hemisphere to another.
Students use miniature explosives to analyze actions and reactions. An Alka-seltzer tablet is sealed in a small film canister with water which sets up a pressure explosion pushing the canister one direction and an adjacent film canister in the opposite direction. Students repeat this set up but vary the mass of the second canister by adding sand. The distances that each canister travels is measured, recorded and later analyzed and discussed.
