This interactive activity, in applet form, guides students through the motion of the sun and how they relate to seasons.

Beginning econometrics students often have an uneven preparation in statistics. The simulation gives students a clearer understanding of the behavior of OLS estimators.

CK-12 Basic Physics - Second Edition updates CK-12 Basic Physics and is intended to be used as one small part of a multifaceted strategy to teach physics conceptually and mathematically.

Students hypothesize whether vinegar and ammonia-based glass cleaner are acids or bases. They create designs on index cards using these substances as invisible inks. After the index cards have dried, they apply red cabbage juice as an indicator to reveal the designs.

This task involves a fairly straightforward decaying exponential. Filling out the table and developing the general formula is complicated only by the need to work with a fraction that requires decisions about rounding and precision.

This is an Excel spreadsheet and graph that illustrates standard "batch" and Rayleigh decarbonation models and how they can be used to detect fluid infiltration during metamorphism of carbonates. It makes a good lecture demonstration, but with a few modifications can be turned into a laboratory exercise. Key variables are "hotlinked" directly into the batch and Rayleigh models so students can adjust them to get a feel for the influence of different model parameters. The included carbon isotope data are from marbles in the Jervois region, central Australia (Cartwright et al., 1997). Oxygen isotope data are also included in the spreadsheet.

This is one component of the Rupturing Continental Lithosphere suite of mini-lessons.
Students investigate the morphology of rifted margins by creating topographic/bathymetric maps and profiles across the Red Sea and the Gulf of California (using GeoMapApp ), and describe north-to-south variations in basin morphology in the Gulf of California (including making graphs using Excel).
This lab exercise will allow students to examine the roles of structural evolution, sedimentation, and physical and chemical evolution of the crust in the rifting process. This lesson can act as an introduction to more detailed examinations of the roles of sedimentation and obliquity in rifted margins.

This task describes two linear functions using two different representations. To draw conclusions about the quantities, students have to find a common way of describing them. We have presented three solutions (1) Finding equations for both functions. (2) Using tables of values. (3) Using graphs.

Students explore the properties of composites using inexpensive materials and processing techniques. They create beams using Laffy Taffy and water, and a choice of various reinforcements (pasta, rice, candies) and fabricating temperatures. Student groups compete for the highest strength beam. They measure flexure strength with three-point bend tests and calculations. Results are compared and discussed to learn how different materials and reinforcement shapes affect material properties and performance.

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful human-made CFCs (chlorofluorocarbons).

This audio excerpt captures the beginning of Bayard Rustin's 1967 "Freedom Budget" speech, describing the social and economic impact of racism over time.

Beginning kindergarteners are introduced to science and engineering concepts through questions such as “What is a Scientist?” and “What is an Engineer?”, and go on to compare and contrast the two. They are introduced to five steps of the engineering design process and explore these steps using the “I do, we do, you do” set of guided instruction. At the end of the project, students produce a set of purple popsicles that they design using various materials and by following a set of criteria.

Participants learn what to do before, during, and after a potentially damaging earthquake. They brainstorm valuable components for an emergency supplies backpack and then present on their ideas. The primary resource is the booklet Are you prepared for the next big EARTHQUAKE in Alaska?

This activity provides students with an in-class practice of landscape interpretation using slides of beaches shown by the instructor. Students view a select number of slides and are asked to classify each beach shown using the Wright and Short Beach Classification: dissipative, reflexive, and intermediate by visually identifying landforms and processes of each beach type. The outcome of this activity is that students have practice identifying landforms and processes and applying their observations and interpretations of geomorphic features and processes for an applied purpose.

In this activity, kids will work on two fundamental early math skills – sorting/classifying, and graphing. There will also be some great fine motor skill practice! Includes place-based discussion questions, activity instructions, extension activities, songs, and student graph worksheets.

NGSS: K-LS1-1, 1-LS1-1, partially meets K-ESS3-1 (book and discussion)

Common Core: MP.4

Time: 45 minutes

Matierals: bag of dried beans ("16 bean soup"), paper bowls, glue, chart paper, the book "One Bean" or similar book about growing food plants, especially beans.

Hunt for prey and discover the meaning of evolutionary “fitness” in this physically active group game. In this simulation game, teams of predators equipped with genetically different “mouths” (utensils) hunt for “prey” (assorted beans). Over several “generations” of play, the fittest among the predators and prey dominate the population, modeling the evolutionary process of natural selection.

Children match pictures of the Moon on cards with matching pictures on a banner that shows the Moon phase cycle.

Accompanying resource to "Bear Shadow Activity." Children learn how the location of a light source changes how shadows appear.

Children find favorite words, phrases, and sentences from familiar stories. Working together, they combine their words and phrases to create a poem. The poem is then shared as performance poetry.

During the course of the day, students examine the high-grade metasupracrustal rocks, related gneisses, and the late Archean granitoids and mafic dikes. We have prepared a number of exercises that might be done with classes at different levels. Depending on the background and preparation of your class you might want to emphasize different learning skills specific to the class level: observation, interpretation, integration (i.e. multiple lines of evidence focused on a given problem), and synthesis (i.e. relationship to the "big picture", drawing from the corpus of geologic knowledge). We have also prepared a compilation of our key scientific results, but these are under seal and we'd like you to do the exercises first as if you were students before taking a look at the supporting evidence.
