The final activity of this unit, which integrates the Keepers of the Gate unit through the Go Public challenge, involves students taking part in experimental design. They design a lab that answers the challenge question: "You are spending the night with your grandmother when your throat starts to feel sore. Your grandma tells you to gargle with salt water and it will feel much better. Thinking this is an old wive's tale, you scoff, but when you try it later that night it works! Why?" Students must have their plan approved by the instructor before they begin. A formal lab write-up is due as part of the laboratory investigation.

This task presents a real-world problem requiring the students to write linear equations to model different cell phone plans. Looking at the graphs of the lines in the context of the cell phone plans allows the students to connect the meaning of the intersection points of two lines with the simultaneous solution of two linear equations.

This simple task assesses whether students can interpret function notation. The four parts of the task provide a logical progression of exercises for advancing understanding of function notation and how to interpret it in terms of a given context.

In this lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. And, students are introduced to the process of bioremediation and several examples of how bioremediation is used during the cleanup of environmental contaminants.

Two lessons and their associated activities explore cellular respiration and population growth in yeasts. Yeast cells are readily obtained and behave predictably, so they are very appropriate to use in middle school classrooms. In the first lesson, students are introduced to yeast respiration through its role in the production of bread and alcoholic beverages. A discussion of the effects of alcohol on the human body is used both as an attention-getting device, and as a means to convey important information at an impressionable age. In the associated activity, students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Based on questions that arise from this activity, in the second lesson students work in small groups as they design and execute their own experiments to determine how environmental factors affect yeast population growth.

Many historians have posed the question: "Was World War II a watershed event in the African-American Civil Rights Movement?" During the war, the "Double V" campaign of the black press called for victory over fascism abroad and racism at home. In this lesson, students will investigate primary-source materials to develop an understanding of the experience of African Americans in the war overseas and on the home front. In doing so, they will consider whether the contradictory gains made in the areas of civil rights, housing, work, and military service represented a break with the past or a continuation of the status quo.
Students will examine the experience of African Americans during World War II by analyzing primary sources and formulating historical questions.
Students will evaluate if the African American experience during World War II represents continuity or change by writing letters to the editor.

This lesson introduces students to the complexity of history by focusing on the diverse activities of Black women in the nineteenth century. Historians have traditionally ignored free black women during this period, and furthermore oversimplified the lives of slave women. Using a variety of sources and documents, students will learn that many Black women, whether born slaves, free, or freed in later life, resisted the system that oppressed them, earned degrees, and became politically active before, during, and after the Civil War.
Students will learn how to read and interpret various primary and secondary sources and how to use them to draw conclusions about the issues that the authors faced during the nineteenth century.
Students will read historical narratives imaginatively and in their proper context.
Students will view evidence of historical perspectives and draw upon visual and literary sources while studying the lives of nineteenth-century black feminists, the issues they faced, and their methods for solving them.

The purpose of this task is to use geometric and algebraic reasoning to model a real-life scenario. In particular, students are in several places (implicitly or explicitly) to reason as to when making approximations is reasonable and when to round, when to use equalities vs. inequalities, and the choice of units to work with (e.g., mm vs. cm).

This activity is a indoor lab where student gather data about centripital acceleration and write up a lab based on their findings.

This video segment explains centripetal force and illustrates how roller coasters rely on it to give you a thrilling ride.

Student groups compete to design a process that removes the most iron from fortified cereal. Students experiment with different materials using what they know about iron, magnets and forces to design the best process for removing iron from the cereal samples.

This activity engages learners in exploring the impact of climate change on arctic sea ice in the Bering Sea. They graph and analyze sea ice extent data, conduct a lab on thermal expansion of water, and then observe how a scientist collects long-term data on a bird population.

Students become familiar with the engineering design process as they design, build and test chair prototypes. The miniature chairs must be sturdy and functional enough to hold a wooden, hinged artist model or a floppy stuffed animal. They use their prototypes to assess design strengths and weaknesses.

Self Discipline is an important factor for academic achievement as much as it is for athletic achievement. This lesson focuses on developing good habits for academic and athletic achievement.

Students teams use a laparoscopic surgical trainer to perform simple laparoscopic surgery tasks (dissections, sutures) using laparoscopic tools. Just like in the operating room, where the purpose is to perform surgery carefully and quickly to minimize patient trauma, students' surgery time and mistakes are observed and recorded to quantify their performances. They learn about the engineering component of surgery.

At its core, the LEGO MINDSTORMS(TM) NXT product provides a programmable microprocessor. Students use the NXT processor to simulate an experiment involving thousands of uniformly random points placed within a unit square. Using the underlying geometry of the experimental model, as well as the geometric definition of the constant π (pi), students form an empirical ratio of areas to estimate a numerical value of π. Although typically used for numerical integration of irregular shapes, in this activity, students use a Monte Carlo simulation to estimate a common but rather complex analytical form the numerical value of the most famous irrational number, π.

Students run a simplified computer model to explore how climate conditions can affect caribou, the most abundant grazing animal in the Arctic.

This activity is a hands-on activity to help students learn the behavior of gas particles.

This animation illustrates how the hardiness zones for plants have changed between 1990 and 2006 based data from 5,000 National Climatic Data Center cooperative stations across the continental United States.
