And Justice for All: the Trail of Tears, Mexican Deportation, and Japanese Internment

(View Complete Item Description)

Many textbooks mention the Trail of Tears, but fail to mention that this early displacement of an ethnic minority is only the one of many legally-sanctioned forced relocations. This lesson will address the displacement of American Indians through the Trail of Tears, the forced deportation of Mexican Americans during the Great Depression, and the internment of Japanese American citizens during WWII.

Digestion Simulation

(View Complete Item Description)

To reinforce students' understanding of the human digestion process, the functions of several stomach and small intestine fluids are analyzed, and the concept of simulation is introduced through a short, introductory demonstration of how these fluids work. Students learn what simulation means and how it relates to the engineering process, particularly in biomedical engineering. The teacher demo requires vinegar, baking soda, water and aspirin.

Developing a Sense of Scale

(View Complete Item Description)

This lesson unit is intended to help you assess whether students recognize relationships of direct proportion and how well they solve problems that involve proportional reasoning. In particular, it is intended to help you identify those students who: use inappropriate additive strategies in scaling problems, which have a multiplicative structure; rely on piecemeal and inefficient strategies such as doubling, halving, and decomposition, and have not developed a single multiplier strategy for solving proportionality problems; and see multiplication as making numbers bigger, and division as making numbers smaller.

Exponents: Take your knowledge to a higher power

(View Complete Item Description)

According to the GED testing service, test takers struggle with “applying rules of exponents in numerical expressions with rational exponents to write equivalent expressions with rational exponents.” (https://www.gedtestingservice.com/uploads/files/09738c12fe4e4accd9a16bab7cb99a3c.pdf ) Students do “fairly well” with simple squares and square roots, but there is a “sharp drop-off” when things get more complicated. These are questions included in the “no calculator” portion of the test. These skills are Mathematics Standards Level D in the College and Career Readiness Standards for Adult Education (https://www.educateiowa.gov/sites/files/ed/documents/CCRStandardsAdultEd.pdf ) under “Expressions and Equations.” This curriculum guide will offer opportunities to build the deeper understanding necessary to understand the rules of exponents such as (xm)n = xmn . Write and evaluate numerical expressions involving whole-number exponents. (6.EE.1) Know and apply the properties of integer exponents to generate equivalent numerical expressions. (8.EE.1)

Laser Types and Uses

(View Complete Item Description)

Through two classroom demos, students are introduced to the basic properties of lasers through various mediums. In the Making an Electric Pickle demonstration, students see how cellular tissue is able to conduct electricity, and how this is related to various soaking solutions. In the Red/Green Lasers through Different Mediums demonstration, students see the properties of lasers, especially diffraction, in various mediums. Follow-up lecture material introduces students to the mechanisms by which lasers function and relates these functions to the properties of light. In the associated activity, student teams research specific laser types and present their findings to the class.

Human Water Cycle

(View Complete Item Description)

Students learn about the human water cycle, or how humans impact the water cycle by settling down in civilizations. Specifically, they learn how people obtain, use and dispose of water. Students also learn about shortages of treated, clean and safe water and learn about ways that engineers address this issue through water conservation and graywater recycling.

Your Sense of Taste

(View Complete Item Description)

Think of some of your favorite tastes: savory Thanksgiving turkey, buttery mashed potatoes, tangy cranberry sauce, and warmly spiced pumpkin pie. We perceive food's complex, layered flavors through the work of five* types of receptors on our tongues—those that detect either sweet, sour, salty, bitter, and umami (savory). These receptors bind to chemicals in our food and transmit the information about the chemicals to our brains, resulting in a healthy appreciation for the nuances of chocolate, coffee, strawberries, and more.
