On Triton, Neptune's largest moon, seasons last an average of 40 years, complete with nitrogen snow. Here's how Triton's summer solstice compares to Earth's.
The video describes the life cycle of stars and how they change from one stage to the next.
This Wakelet is a collection of links to free online resources that address all areas of teaching the Next Generation Science Standards (NGSS). The resources are grouped together in smaller, topic-based collections. A range of resources are provided for K-12, and additional links will be continually added to the collection.
Our Patterns Chemistry development team of teacher leaders has been working hard through the spring and summer of 2020 to develop distance learning versions of the Patterns Chemistry units. Between March and May they released the below Distance Learning versions of units 4, 5 and 6, as well as paper packets that can be printed for students who do not have access to technology at home. Below are the distance learning version of units 1 and unit 2. The distance learning units can be used in either a fully online or hybrid school model. A Distance Learning version of Unit 3 will be released by the end of September. For schools reopening fully in person, scroll down to see the original Patterns Chemistry unit plans.
THE PATTERNS APPROACH
The Patterns Approach to science instruction emphasizes the use of mathematical and phenomenological patterns to predict the future and understand the past. Students construct science knowledge by making an initial “wild-guess”, asking questions, planning and conducting experiments, collecting data, finding a mathematical model that fits their data, explaining the phenomenon based on that model, then finally making a data-informed prediction. Harnessing their own experiences, students compare and contrast low-evidence predictions (wild guesses) to their data-informed prediction to live the experience and learn the value of evidence-based reasoning. Additionally, students engage in several engineering projects in each course, where they must use the Patterns they discover in their designs to optimize their solutions. The Patterns Approach utilizes technology, student-constructed knowledge, frequent opportunities for student talk, and language supports to ensure the engagement and success of every student. By emphasizing, rather than removing, the mathematical connections to science, the Patterns Approach supports student conceptual understanding by connecting real-world inquiry experiences, graphical representations, and mathematical representations of science phenomena.
