Towards finding a solution to the unit's Grand Challenge Question about using nanoparticles to detect, treat and protect against skin cancer, students continue the research phase in order to answer the next research questions: What is the structure and function of skin? How does UV radiation affect the chemical reactions that go on within the skin? After seeing an ultraviolet-sensitive bead change color and learning how they work, students learn about skin anatomy and the effects of ultraviolet radiation on human skin, pollution's damaging effect on the ozone layer that can lead to increases in skin cancer, the UV index, types of skin cancer, ABCDEs of mole and lesion evaluation, and the sun protection factor (SPF) rating system for sunscreens. This prepares students to conduct the associated activity, in which they design quality-control experiments to test SPF substances.

Skyscrapers are one of the most glorified products of Civil Engineering and contain an interesting history of progress and development. In this lesson, the students will learn about the history of the world's tallest free standing structures and the basic design principles behind their success. Students will build their own newspaper skyscrapers with limited materials and time, trying to achieve a maximum height and the ability to withstand a "hurricane wind" force. Discussion will concentrate on materials, forces that a skyscraper needs to withstand, and basic structural design.

The realities of slavery and Reconstruction hit home in poignant oral histories from the Library of Congress. In these activities, students research narratives from the Federal Writers' Project and describe the lives of former African slaves in the U.S. -- both before and after emancipation. From varied stories, students sample the breadth of individual experiences, make generalizations about the effects of slavery and Reconstruction on African Americans, and evaluate primary source documents.

Students explore building a pyramid, learning about the simple machine called an inclined plane. They also learn about another simple machine, the screw, and how it is used as a lifting or fastening device. During a hands-on activity, students see how the angle of inclination and pull force can make it easier (or harder) to pull an object up an inclined plane.

This unit uses the slinky seismometer as a means of studying physics concepts such as waves, sound and the speed of sound vs speed of light, resonance, electricity and magnetism, Lenz Law and magnetic dampening (backwards engineering). Students experiment with the basic parts of the seismometer and either build or connect the seismometer to the internet to take and upload data.

Students learn the basics about soil, including its formation, characteristics and importance. They are also introduced to soil profiles and how engineers conduct site investigations to learn about soil quality for development, contamination transport, and assessing the general environmental health of an area.
Students learn about the daily and annual cycles of solar angles used …
Students learn about the daily and annual cycles of solar angles used in power calculations to maximize photovoltaic power generation. They gain an overview of solar tracking systems that improve PV panel efficiency by following the sun through the sky.
In this project students will research and then build a basic solar …
In this project students will research and then build a basic solar cooker shell made out of cardboard. Then they will run a variety of materials through experiments. Data from the experiments will be used to determine which materials should be added to the solar cooker shell to improve its ability to heat up food.
This project was created as a collaboration between a science and an engineering/woodshop class. The engineering class researched and build the basic solar cooker cardboard shells. The science class tested additional materials to add to the shells to improve the solar cookers. Then the engineering class, following the directions from reports created by the science class, added the materials to the solar cooker shells to create the final products.
Students learn about solar energy and how to calculate the amount of …
Students learn about solar energy and how to calculate the amount of solar energy available at a given location and time of day on Earth. The importance of determining incoming solar energy for solar devices is discussed.

The students will paint and arrange spheres to form a model of the solar system. They will first make models using the plastic spheres of different sizes. Then they will make similar models using clay, cotton, etc., and organize them in the right order from the Sun.
This activity is based on a reduced-scale model of the Solar System …
This activity is based on a reduced-scale model of the Solar System built on a map of a city students are familiar with. This provides them with an understanding of the great distances between the different bodies of the Solar System and their relative size. Students will investigate the characteristics that are required from these bodies to build a scale model using common objects.

This lesson discusses solenoids. Students learn how to calculate the magnetic field along the axis of a solenoid and complete an activity exploring the magnetic field of a metal slinky. Solenoids form the basis for the magnet of an MRI. Exploring the properties of this solenoid helps students understand the MRI machine.

Students are given a variety of materials and asked to identify each material as a solid, liquid or gas. They use their five senses ŰÓ sight, sound, smell, texture and taste ŰÓ to identify the other characteristics of each item.
In this lesson, students explore solid waste and its effects on the …
In this lesson, students explore solid waste and its effects on the environment. They will collect classroom trash for analysis and build model landfills in order to understand the process and impact of solid waste management. Students will understand the role of engineers in solid waste management.

Represent inequalities on a number line. Represent inequalities using interval notation. Use the addition and multiplication properties to solve algebraic inequalities and express their solutions graphically and with interval notation. Solve inequalities that contain absolute values. Combine properties of inequalities to isolate variables, solve algebraic inequalities, and express their solutions graphically. Simplify and solve algebraic inequalities using the distributive property to clear parentheses and fractions.

Sor Juana Inés de la Cruz, la primer gran poeta de América Latina, es considerada una de la figuras literarias más importantes del continente americano y una de las primeras feministas. En el siglo XVII, defendió su derecho a la educación, proponiendo la mayor participación de las mujeres en la cultura y la pedagogía en una sociedad dominada por los hombres.

Sor Juana Ines de la Cruz, the first great Latin American poet, is still considered one of the most important literary figures of the American Hemisphere, and one of the first feminist writers. In the 1600s, she defended her right to be an intellectual, suggesting that women should be educated and educators and accusing men of being the cause of the very ills they blamed on women.

In this project, students will use knowledge of electricity and electromagnetism to collaboratively design and test a model of a magnetic recycling sorter. They will evaluate the performance of their models and propose further modifications based on the output of their magnetic device measured in mT using a Vernier probe. They will also physically test their magnets on a model of a conveyor belt containing recyclable items. Students will track their data from both tests, with the ultimate goal of creating the strongest and most effective magnet with given materials. Finally, students will present their findings and proposed final design to peers and community partners involved in the recycling industry. The entire process takes about 6 weeks. The unit is a great fit for standards within energy and engineering & design.
