In this lesson, students expand their understanding of solid waste management to include the idea of 3RC (reduce, reuse, recycle and compost). They will look at the effects of packaging decisions (reducing) and learn about engineering advancements in packaging materials and solid waste management. Also, they will observe biodegradation in a model landfill (composting).

How does a one-way mirror work? Though most everyone knows that one-way mirrors exist, having students model how they work turns out to be a very effective way to develop their thinking about how visible light travels and how we see images. Initial student models reveal a wide variety of ideas and explanations that motivate the unit investigations that help students figure out what is going on and lead them to a deeper understanding of the world around them.

As the first unit in the OpenSciEd program, during the course of this unit, students also develop the foundation for classroom norms for collaboration that will be important across the whole program.

The goals of OpenSciEd are to ensure any science teacher, anywhere, can access and download freely available, high quality, locally adaptable full-course materials. REMOTE LEARNING GUIDE FOR THIS UNIT NOW AVAILABLE!

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.

To pique students’ curiosity and anchor the learning for the unit in the visible and concrete, students start with an experience of observing and analyzing a bath bomb as it fizzes and eventually disappears in the water. Their observations and questions about what is going on drive learning that digs into a series of related phenomena as students iterate and improve their models depicting what happens during chemical reactions. By the end of the unit, students have a firm grasp on how to model simple molecules, know what to look for to determine if chemical reactions have occurred, and apply their knowledge to chemical reactions to show how mass is conserved when atoms are rearranged.

This unit on metabolic reactions in the human body starts out with students exploring a real case study of a middle-school girl named M’Kenna, who reported some alarming symptoms to her doctor. Her symptoms included an inability to concentrate, headaches, stomach issues when she eats, and a lack of energy for everyday activities and sports that she used to play regularly. She also reported noticeable weight loss over the past few months, in spite of consuming what appeared to be a healthy diet. Her case sparks questions and ideas for investigations around trying to figure out which pathways and processes in M’Kenna’s body might be functioning differently than a healthy system and why.

Students investigate data specific to M’Kenna’s case in the form of doctor’s notes, endoscopy images and reports, growth charts, and micrographs. They also draw from their results from laboratory experiments on the chemical changes involving the processing of food and from digital interactives to explore how food is transported, transformed, stored, and used across different body systems in all people. Through this work of figuring out what is causing M’Kenna’s symptoms, the class discovers what happens to the food we eat after it enters our bodies and how M’Kenna’s different symptoms are connected.

Students figure out that they can trace all food back to plants, including processed and synthetic food. They obtain and communicate information to explain how matter gets from living things that have died back into the system through processes done by decomposers. Students finally explain that the pieces of their food are constantly recycled between living and nonliving parts of a system.

Students will be reading and writing myths. They will follow the structure of short stories and eventually publish their work.

The 7th grade poetry unit gives an in depth approach to poetry involving the four strands within the core. I've included worksheets, rubrics, and answers keys where applicable. I have also used literature examples from the core.

Oh, no! I’ve dropped my phone! Most of us have experienced the panic of watching our phones slip out of our hands and fall to the floor. We’ve experienced the relief of picking up an undamaged phone and the frustration of the shattered screen. This common experience anchors learning in the Contact Forces unit as students explore a variety of phenomena to figure out, “Why do things sometimes get damaged when they hit each other?”

Student questions about the factors that result in a shattered cell phone screen lead them to investigate what is really happening to any object during a collision. They make their thinking visible with free-body diagrams, mathematical models, and system models to explain the effects of relative forces, mass, speed, and energy in collisions. Students then use what they have learned about collisions to engineer something that will protect a fragile object from damage in a collision. They investigate which materials to use, gather design input from stakeholders to refine the criteria and constraints, develop micro and macro models of how their solution is working, and optimize their solution based on data from investigations. Finally, students apply what they have learned from the investigation and design to a related design problem.

Students will be creating a variety of poetry as well as analyzing poetry. They will work with Language standards and take a performance assessment at the end of the unit.

This lesson explores the challenges the United States faced as a result of the terrorist attacks on September 11, 2001, and examines the governmentâ"s response through the lens of protection and civil liberties. Students will consider the balance between security and liberty in the United States.

This lesson explores the challenges the United States faced as a result of the terrorist attacks on September 11, 2001, and examines the government's response through the lens of protection and civil liberties. Students will consider the long-term effects of the emergency measures, their consequences and constitutionality, and how they might inform the balance between security and liberty today.

The anniversaries of the terrorist attacks on the United States on September 11, 2001, and the signing of the Constitution on September 17, 1787, provide us an opportunity to reflect upon who we are as Americans, examine our most fundamental values and principles and affirm our commitment to them, and evaluate progress toward the realization of American ideals and propose actions that might narrow the gap between these ideals and reality. These lessons are designed to accomplish these goals.

V is for vocabulary. A content area unit provides the theme for a specialized ABC book, as students select, research, define, and illustrate a word for each alphabet letter.

This lesson is designed to help educators find out how familiar their students are with letters and words and also give students an opportunity to develop their fine motor skills.

This lesson introduces children to different ways young people have used the internet to work toward positive social change.

This lesson starts by showing children some of the kinds of advertisements they might run into online and helping them analyze these ads with a critical eye.

Adapting the song "A-Hunting We Will Go," students put a "whale" in a "pail" and even "take a little "bear" and hug it if we "dare"."

Review America’s founding documents from a typical course of study for an AP Government class and understand these essential documents better—including their fundamental ideas and the major principles underlying the U.S. Constitution. Primary sources include the Declaration of Independence, the Articles of the Confederation, the Constitution (including the Bill of Rights), The Federalist Papers (#51, #70, #78), Brutus #1, and Martin Luther King Jr.’s Letter from the Birmingham City Jail.
