This set of resources is from Tools 4 NC Teachers.

This file contains a set of 6 lessons to be used during the first week(s) of school to develop students' mathematical mindsets. Lessons include:
Lesson 1: What is Math?
Lesson 2: Mathematicians Work Together
Lesson 3: Mathematicians Cooperate
Lesson 4: Mathematicians Ask Questions
Lesson 5: Mathematicians Learn from Mistakes
Lesson 6: Mathematicians Persevere

This lab activity is designed to allow students to experience what an increase in mechanical advantage means. Students determine the mechanical advantage of three pulley set-ups. Students also measure the work input and output, then calculate the efficiency. Finally, students determine the relationship between the mechanical advantage and the efficiency of the pulleys.

In this two-part activity, students design and build Rube Goldberg machines. This open-ended challenge employs the engineering design process and may have a pre-determined purpose, such as rolling a marble into a cup from a distance, or let students decide the purposes.

Demos and activities in this lesson are intended to illustrate the basic concepts of energy science -- work, force, energy, power etc. and the relationships among them. The "lecture" portion of the lesson includes many demonstrations to keep students engaged, yet has high expectations for the students to perform energy related calculations and convert units as required. A homework assignment and quiz are used to reinforce and assess these basic engineering science concepts.

The 11th grade learning experience consists of 7 mostly month-long units aligned to the Common Core State Standards, with available course material for teachers and students easily accessible online. Over the course of the year there is a steady progression in text complexity levels, sophistication of writing tasks, speaking and listening activities, and increased opportunities for independent and collaborative work. Rubrics and student models accompany many writing assignments.Throughout the 11th grade year, in addition to the Common Read texts that the whole class reads together, students each select an Independent Reading book and engage with peers in group Book Talks. Students move from learning the class rituals and routines and genre features of argument writing in Unit 11.1 to learning about narrative and informational genres in Unit 11.2: The American Short Story. Teacher resources provide additional materials to support each unit.

In this unit, students will take a look at the historical vision of the American Dream as put together by our Founding Fathers. They will be asked: How, if at all, has this dream changed? Is this dream your dream? First students will participate in an American Dream Convention, acting as a particular historical figure arguing for his or her vision of the American Dream, and then they will write an argument laying out and defending their personal view of what the American Dream should be.

ACCOMPLISHMENTS

Students read and annotate closely one of the documents that they feel expresses the American Dream.
Students participate in an American Dream Convention, acting as a particular historical figure arguing his or her vision of the American Dream.
Students write a paper, taking into consideration the different points of view in the documents read, answering the question “What is the American Dream now?”
Students write their own argument describing and defending their vision of what the American Dream should be.

GUIDING QUESTIONS

These questions are a guide to stimulate thinking, discussion, and writing on the themes and ideas in the unit. For complete and thoughtful answers and for meaningful discussions, students must use evidence based on careful reading of the texts.

What has been the historical vision of the American Dream?
What should the American Dream be? (What should we as individuals and as a nation aspire to?)
How would women, former slaves, and other disenfranchised groups living during the time these documents were written respond to them?

BENCHMARK ASSESSMENT: Cold Read

During this unit, on a day of your choosing, we recommend you administer a Cold Read to assess students’ reading comprehension. For this assessment, students read a text they have never seen before and then respond to multiple-choice and constructed-response questions. The assessment is not included in this course materials.

In this lesson, students will take their group's feedback into account and revise their final paper.

Simple machines are devices with few or no moving parts that make work easier, and which people have used to provide mechanical advantage for thousands of years. Students learn about the wedge, wheel and axle, lever, inclined plane, screw and pulley in the context of the construction of a pyramid, gaining insights into tools that have been used since ancient times and are still important today. Through numerous hands-on activities, students imagine themselves as ancient engineers building a pyramid. Student teams evaluate and select a construction site, design a pyramid, perform materials calculations, test a variety of cutting wedges on different materials, design a small-scale cart/lever transport system to convey building materials, experiment with the angle of inclination and pull force on an inclined plane, see how a pulley can change the direction of force, and learn the differences between fixed, movable and combined pulleys. While learning the steps of the engineering design process, students practice teamwork, creativity and problem solving.

Students will explore the definition of energy by making careful observations about simple toys that illustrate basic principles of energy.

This is an introductory activity that introduces the concept of work and helps students understand the difference between work and energy in terms of pulling and lifting masses.

This video shows two different student-generated strategies for solving fair share problems leading to a fraction less than 1. This standard relates to Common Core standard 5.NF.3, and North Carolina standard NC.5.NF.3.

The end of this video helps teachers see how standard NF.3 can be introduced prior to NF.1 (addition/subraction of fractions with unlike denominators).

Students discover the scientific basis for the use of inclined planes. Using a spring scale, a bag of rocks and an inclined plane, student groups explore how dragging objects up a slope is easier than lifting them straight up into the air. Also, students are introduced to the scientific method and basic principles of experimentation. To conclude, students imagine and design their own uses for inclined planes.

Students do work by lifting a known mass over a period of time. The mass and measured distance and time is used to calculate force, work, energy and power in metric units. The students' power is then compared to horse power and the power required to light 60-watt light bulbs.

Students are introduced to the concept of simple tools and how they can make difficult or impossible tasks easier. They begin by investigating the properties of inclined planes and how implementing them can reduce the force necessary to lift objects off the ground.

Students continue to explore the story of building a pyramid, learning about the simple machine called a pulley. They learn how a pulley can be used to change the direction of applied forces and move/lift extremely heavy objects, and the powerful mechanical advantages of using a multiple-pulley system. Students perform a simple demonstration to see the mechanical advantage of using a pulley, and they identify modern day engineering applications of pulleys. In a hands-on activity, they see how a pulley can change the direction of a force, the difference between fixed and movable pulleys, and the mechanical advantage gained with multiple / combined pulleys. They also learn the many ways engineers use pulleys for everyday purposes.

In this hands-on activity rolling a ball down an incline and having it collide into a cup the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables, and review the relationships between these concepts.

This article describes Katy Farness' work with the Byrd Polar Research Center at the Ohio State University. Farness used remote sensing images and computer technology to create detailed images of Antarctica and the ice sheets of Greenland.

Students predict where a ball will land when released using knowledge of projectile motion and potential and kinetic energy.

In this lesson students investigate how the distance of stretch in a rubber band at rest relates to the distance the rubber band travels after being released. Students will be pulling rubber bands back to five different stretch lengths. They will then measure how far the rubber bands fly when released from the different stretch lengths and then record the results down in a data table.

Students are challenged to create simple machines out of everyday objects to complete specific tasks.
