Children design and build a vehicle for exploring another world, using recycled materials.
Students create their own anemometers instruments for measuring wind speed. They see how an anemometer measures wind speed by taking measurements at various school locations. They also learn about different types of anemometers, real-world applications, and how wind speed information helps engineers decide where to place wind turbines.
In association with rock and mineral ID tables, this lab introduces students to basic rocks and minerals via grouping and comparison, rather than as individual samples. I use this lab in my environmental geology course, where we don't have enough lab time to examine each set of rocks and minerals separately, but students need a basic familiarity with these materials and a context in which to place them. I find these groupings teach them how to look at rocks and minerals and give them the cursory experience identifying geologic materials necessary to go on successfully in the course.

The city of Fort Collins, Colorado, found a win-win solution to problems it faced with 100 acres of abandoned property. The city now enjoys new green space, improved floodwater management, and a boosted economy.
Educators with an interest in hands-on science, technology, engineering and mathematics (STEM) disciplines will receive introductory instructions on how to design, engineer and build a fully functional underwater ROV.

Students investigate the weather from a systems approach, learning how individual parts of a system work together to create a final product. Students learn how a barometer works to measure the Earth's air pressure by building a model using simple materials. Students analyze the changes in barometer measurements over time and compare those to actual weather conditions. They learn how to use a barometer to understand air pressure and predict actual weather changes.
Facies models are often abstract and difficult for undergraduate students to fully understand. As a result, they tend to memorize idealized diagrams from text books that can be reproduced for an exam, then forgotten.
The purpose of this exercise is to help students understand a model by "building" it "piece by piece" and relating the various components to concepts they learned earlier in the semester, such as energy relationships, base level, facies, facies associations, and Walther's Law. It is designed to begin as an in-class discussion led by the instructor using a black or white board, followed by group collaboration, out-of-class exercises, and concluding with a formal examination.
The example provided here is for a prograding shoreface system; however, the same approach can be applied to any depositional system.
Students learn about refracting telescopes in this Moveable Museum unit, in which they construct a simple telescope. The three-page PDF guide includes suggested general background readings for educators, activity notes, step-by-step directions, and information about where to obtain supplies.
Students learn about the variations of white light in this Moveable Museum unit, in which they build a pocket-sized spectroscope from readily available materials and examine different light sources in school, at home, and around their town or city. The seven-page PDF guide includes suggested general background readings for educators, activity and safety notes, step-by-step directions, and a spectroscope template.
The purpose of this exercise is to guide students through the process of constructing a stratigraphic sequence based on understanding relationships between the production of space and filling that space with sediment.
Students use their knowledge of tornadoes and damage. The students will work in groups to design a structure that will withstand and protect people from tornadoes. Each group will create a poster with the name of their engineering firm and a picture of their structure. Finally, each group will present their posters to the class.
In this activity, students look at how sediments compact as they are buried in a subduction zone and explore how rapid burial can lead to increased water pressure.

This video segment, from the 'Earth: The Operators' Manual' featuring climate expert Richard Alley, shows how ice cores stored at the National Ice Core Lab provide evidence that ancient ice contains records of Earth's past climate - specifically carbon dioxide and temperature.
There is growing body of evidence to support that students who directly experience authentic scientific research are more likely to continue onto advanced degrees and careers in Science, Technology, Engineering and Mathematics (STEM). In an effort to introduce more students to the benefits of scientific research we have drawn on an ongoing research project aimed at understanding how Corals Respond to the Environment (CRE) to develop an interdisciplinary laboratory course based on Authentic Research Experiences (ARE). A small cohort of undergraduate students enrolled in a semester-long course, entitled CREARE, perform biochemical experiments in the laboratory, analyze environmental data by R statistical software and prepared a report modeled after a research manuscript to present their work. The impact of CREARE on student learning gains and attitudes towards science is being measured, as is the impact of CREARE on participants' career choices and retention in STEM. This multidisciplinary research program addresses the impact of climate change on the health of a critically endangered coral species, ultimately leading to a better stewardship of this invaluable resource. Furthermore, CREARE offers a unique experience for students, one that may serve as a model for the development of more research-based courses, leading to improved retention in our STEM departments.

C-ROADS is a simplified version of a climate simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.
In this lab exercise, students examine one or more metamorphic rocks and use various approaches to estimating and calculating the pressure-temperature conditions at which the rocks equilibrated. The exercise involves hand sample description, petrography, interpretation of phase diagrams, and calculations of a phase diagram or P-T conditions from given equations.
In this lab activity, students learn about the relationships between sea level and glaciers during glacial and interglacial periods. First the students need to calculate the maximum sea level rise assuming all water stored in glaciers and ice caps will melt. Then, they are asked to calculate the ice sheet distribution during the last glacial maxima based on the information that sea level dropped by 125 m.

Students will observe the patterns of apparent motion of the sun using simple tools.
Science students often have difficulty thinking about large spatial scales. The purpose of the exercise is to redo Eratosthenes' calculation of the radius of the Earth using data from to sites in ancient Egypt. The excercise teaches about the methodology of science - how Eratothenes figured it out - rather than worried about what the "right" answer is. It can also be used to discuss the role of models in geological thinking.
