This unit on weather, climate, and water cycling is broken into four separate lesson sets. In the first two lesson sets, students explain small-scale storms. In the third and fourth lesson sets, students explain mesoscale weather systems and climate-level patterns of precipitation. Each of these two parts of the unit is grounded in a different anchoring phenomenon.

This task examines the ways in which the plane can be covered by regular polygons in a very strict arrangement called a regular tessellation. These tessellations are studied here using algebra, which enters the picture via the formula for the measure of the interior angles of a regular polygon (which should therefore be introduced or reviewed before beginning the task). The goal of the task is to use algebra in order to understand which tessellations of the plane with regular polygons are possible.

Students create acrostic poems using their names and the names of things that are important to them.

Students are often asked to perform speeches, but rarely do we require students to analyze speeches as carefully as we study works of literature. In this unit, students are required to identify the rhetorical strategies in a famous speech and the specific purpose for each chosen device. They will write an essay about its effectiveness and why it is still famous after all these years.

In this lesson students use the Informational Text Analysis Tool to deconstruct the essential elements of informational text. Informational text is more important to teachers than ever before, especially with the rise of the new Core standards. The Library of Congress is an excellent resource for finding and using texts to build students' reading skills.Through a diverse array of classic and contemporary literature as well as challenging informational and primary source texts, students build knowledge, gain insights, explore possibilities, and broaden their perspective.

With a continued focus on the Sonoran Desert, students are introduced to the concepts of biomes, limiting factors (resources), carrying capacity and growth curves through a PowerPoint® presentation. Abiotic factors (temperature, annual precipitation, seasons, etc.) determine the biome landscape. The vegetative component, as producers, determines the types of consumers that form its various communities. Students learn how the type and quantity of available resources defines how many organisms can be supported within the community, as well as its particular resident species. Students use mathematical models of natural relationships (in this case, sigmoid and exponential growth curves) to analyze population information and build upon it. With this understanding, students are able to explain how carrying capacity is determined by the limiting factors within the community and feeding relationships. By studying these ecological relationships, students see the connection between ecological relationships of organisms and the fundamentals of engineering design, adding to their base of knowledge towards solving the grand challenge posed in this unit.

The unit focuses on the question How can people help end pandemics? It is designed to teach students about the COVID-19 pandemic, transmission of the COVID-19 virus, and the impacts of the pandemic on communities. Over the course of the unit, students will study the COVID-19 pandemic in light of historical pandemics to build an understanding of the following key concepts:

• How the COVID-19 virus spreads from person to person and through communities,
• How strategies to reduce transmission of COVID-19 work,
• How the actions of individuals can help to end pandemics.

The unit also supports the development of two social emotional competencies: self awareness and social awareness.

To kick off the final unit of this course, students will do some research into interesting innovations in computing. This lesson will expose students to wider variety of computing form factors (what a computer looks like) and fields that are impacted by computing. Later in this unit students will look back on the devices they encountered in this lesson as they develop their own physical computing devices.

This series of videos focusing on calculus covers sample questions from the A.P, Calculus AB and AC exams (both multiple choice and free answer).

In this media-rich lesson, students explore careers in science through profiles of Alaska Native scientists. They consider how traditional ways of knowing and Western approaches to science can complement each other and allow students to incorporate their own interests when considering careers in science.

Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle. They view online animations of cell membrane dynamics (links provided). Then they observe three teacher demonstrations that illustrate diffusion and osmosis concepts, as well as the effect of movement through a semi-permeable membrane using Lugol's solution.

This exemplar has been developed to guide high school students and instructors in a close reading of Lincoln's Gettysburg Address. The activities and actions described below follow a carefully developed set of steps that assist students in increasing their familiarity and understanding of Lincoln's speech through a series of text dependent tasks and questions that ultimately develop college and career ready skills identified in the Common Core State Standards. This unit can be broken down into three sections of instruction and reflection on the part of students and their teachers, which is followed by additional activities, some designed for history/social studies and some for ELA classrooms.his close reading exemplar is intended to model how teachers can support their students as they undergo the kind of careful reading the Common Core State Standards require. Teachers are encouraged to take these exemplars and modify them to suit the needs of their students.

Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint") on strips of filter paper and then place one paper strip end in water. As water travels along the paper strips, students observe the pigments that compose the paint decompose into their color components. This is an example of the chromatography concept applied to DNA forensics, with the pigments in the paint that define the color being analogous to DNA fragments of different lengths.

This short video and interactive assessment activity is designed to teach fourth graders about completing the expanded forms of numbers (place values to 1,000).

Students learn about the structure of the earth and how an earthquake happens. In one activity, students make a model of the earth including all of its layers. In a teacher-led demonstration, students learn about continental drift. In another activity, students create models demonstrating the different types of faults.

Students experiment with an online virtual laboratory set at a skate park. They make predictions of graphs before they use the simulation to create graphs of energy vs. time under different conditions. This simulation experimentation strengths their comprehension of conservation of energy solely between gravitational potential energy and kinetic energy
