This resource consists of a Java applet and expository text. The applet illustrates the Galton board in which a ball falls through a triangular array of pegs. Various combinatorial ideas are illustrated, including combinations, bit strings, and binomial coefficients.

This resource consists of a Java applet and expository text. The applet simulates a random sample from a gamma distribution, and computes standard point estimates of the shape and scale parameters. The bias and mean square error are also computed.

In this activity, students study gas laws at a molecular level. They vary the volume of a container at constant temperature to see how pressure changes (Boyle's Law), change the temperature of a container at constant pressure to see how the volume changes with temperature (Charles’s Law), and experiment with heating a gas in a closed container to discover how pressure changes with temperature (Gay Lussac's Law). They also discover the relationship between the number of gas molecules and gas volume (Avogadro's Law). Finally, students use their knowledge of gas laws to model a heated soda can collapsing as it is plunged into ice water.

This activity allows students to work through a series of games to learn about DNA, protein bases, and how they combine, dominant and recessive genes, Punnett Squares and genotypes, and phenotypes. 

The Geniverse software is being developed as part of a five-year research project funded by the National Science Foundation. Still in its early stages, a Beta version of the software is currently being piloted in six schools throughout New England. We invite you to try the current Beta version, keeping in mind that you may encounter errors or pages that are not fully functional. If you encounter any problem, it may help to refresh or reload the web page.

The German Frame-semantic Online Lexicon (G-FOL) is a prototype of a new kind of pedagogical dictionary. The goal is to help students learn how words are used in modern-day German. This online resource is different from traditional dictionaries and textbooks because it is based on the German FrameNet at the University of Texas at Austin, a digital archive of how German words are used in real life contexts. As such, students can easily access up-to-date information about the syntactic, semantic, and pragmatic contexts in which a German word appears. In addition, each lexical entry provides information about a word’s register, frequency, and related meanings. Thanks to G-FOL’s web-based architecture, the lexicon easily links to other pedagogical resources in digital format and can be updated with new words or new usages of existing words.

Teach and learn practical digital skills needed for the jobs of today and tomorrow with our video lessons that are free of charge.

Students will organize various stem items, make observations regarding those items such as their color, size, etc and then graph their observations.

This is an exploratory activity.  Students should have some prior knowledge of evaluating functions for given domain inputs using function notation.This lesson will walk students through using a table and plotting points.  By the end of the lesson students should walk away understanding that a line is infinitely many points.

The 7 Cups and VBCPS Growth PathsPersonalized Growth Paths contain activities made for those dealing with a certain situation. It helps a person understand what they are dealing with and self-heal with activities that are expertly compiled.There is also a “gamified” element to the Paths. Students complete “Steps” to fill their cups and move ahead on their chosen path.You can find text, slides, and videos  here or the Gratitue Growth Path on 7 Cups as well with a free membership.

Great activity on what makes a swamp a swamp. This activity will also allow students to learn about the swamp that is located in Virginia and North Carolina. This activity is designed to have students use technology, conduct research, and create a Google Slides presentation.

Who were the Ancient Greeks? Explore more about the Ancient Greeks and what they valued as a society in this Interactive Exploration.

This resource consists of two different types of looking, thinking and learning activities. These activities call on students' observation and critical thinking skills as they closely examine selected objects from Ancient Greece. The activities explore the themes of mythology, religion, sport, and trade.

The "Look at This" activities provide close-up views with guiding questions and background information. Students will learn more about what the ancient Greeks valued as a society.

The "Surprise Me" activities offer pop-up hot spots on selected objects to reveal intriguing information about Greek religion, gods, goddesses, trade, sport and mythology. Students will investigate how these objects relate to Greek religion and human need for protection from harm and healing from disease and injury.

This lesson will allow students to add and subtract with decimals, as well as use estimation, using a practical application.

These hands-on, minds-on activities engage students in experiments or simulation activities and incorporate multiple questions designed to foster student understanding of important concepts in the life sciences. Topics covered include biological molecules, diffusion, metabolism, cell division, genetics, molecular biology, evolution, diversity, human physiology and design and interpretation of experiments. These activities were designed for teaching high school or middle school students, but many of these activities can also be used in non-major introductory college biology classes. To accommodate limited budgets, most of these activities can be carried out with minimum equipment and expense for supplies. Additional minds-on activities for teaching biology, including discussion activities, are available at http://serendip.brynmawr.edu/exchange/bioactivities. Most of the activities are described in student handouts and teacher notes; the student handouts are available as Word files for teachers to customize for their students.

Students will explore the "story" that can be interpreted from graphs. Graphical representations can be created by looking at videos of different situations on Desmos. After noticing that all types of linear slopes (zero, positive, and negative) can be included in a given situation, students create a graphical representation to show a change in heart rate overtime.

Students interact with Scratch to review continents and oceans. Students edit a Scratch template to begin to explore code. 

This interactive graphic, produced in partnership with Virtual Virginia, features a photo of a stereotypical teenager’s room, with hover-activated graphics that include text describing common hiding places for vapes and related objects.

This is an instructional strategy that has students work in small groups to construct a "honeycomb" that analyzes a text's structure. Students are given a set of ten honeycomb cards connected to their text and then must work together to assemble the honeycomb by ensuring that all connecting cards can be logically connected through careful analysis of the text. If they cannot successfully argue the connection between literary elements, they must reorganize the honeycomb until all the pieces work together seamlessly. This is a learning strategy that works well during a text unit (as opposed to before or after the unit) and is designed to help students understand the intentionality of a text's structure. It can be paired with any text, but I have provided a sample card set for "Frankenstein" and "The Picture of Dorian Gray" in this resource.
