Students hypothesize whether vinegar and ammonia-based glass cleaner are acids or bases. They create designs on index cards using these substances as invisible inks. After the index cards have dried, they apply red cabbage juice as an indicator to reveal the designs.

Students learn the basics of acid/base chemistry in a fun, interactive way by studying instances of acid/base chemistry found in popular films such as Harry Potter and the Prisoner of Azkaban and National Treasure. Students learn what acids, bases and indicators are and how they can be used, including invisible ink. They also learn how engineers use acids and bases every day to better our quality of life. Students' interest is piqued by the use of popular culture in the classroom.

Understanding the basic needs for survival is a foundational science concept. This interactive lesson introduces the students to the concept of needs through a popular children's book.

"This course covers the following questions. What are the predominant heat producing elements of the Earth? Where and how much are they? Are they present in the core of the Earth? Detection of antineutrinos generated in the Earth provides: 1) information on the sources of the terrestrial heat, 2) direct test of the Bulk Silicate Earth (BSE) model and 3) testing of non-conventional models of Earth's core. Use of antineutrinos to probe the deep interior of our planet is becoming practical due to recent fundamental advances in the antineutrino detectors."

Fluid mechanics deals with the study of all fluids under static and dynamic situations. Fluid mechanics is a branch of continuous mechanics which deals with a relationship between forces, motions, and statical conditions in a continuous material. This study area deals with many and diversified problems such as surface tension, fluid statics, flow in enclose bodies, or flow round bodies (solid or otherwise), flow stability, etc. In fact, almost any action a person is doing involves some kind of a fluid mechanics problem. Furthermore, the boundary between the solid mechanics and fluid mechanics is some kind of gray shed and not a sharp distinction (see Figure 1.1 for the complex relationships between the different branches which only part of it should be drawn in the same time.). For example, glass appears as a solid material, but a closer look reveals that the glass is a liquid with a large viscosity. A proof of the glass ``liquidity'' is the change of the glass thickness in high windows in European Churches after hundred years. The bottom part of the glass is thicker than the top part. Materials like sand (some call it quick sand) and grains should be treated as liquids. It is known that these materials have the ability to drown people. Even material such as aluminum just below the mushy zone also behaves as a liquid similarly to butter. Furthermore, material particles that "behaves'' as solid mixed with liquid creates a mixture After it was established that the boundaries of fluid mechanics aren't sharp, most of the discussion in this book is limited to simple and (mostly) Newtonian (sometimes power fluids) fluids which will be defined later.

This book describes the fundamentals fluid mechanics phenomena for engineers and others. It is designed to replace all introductory textbook(s) or instructor's notes for the fluid mechanics in undergraduate classes for engineering/science students but also for technical peoples. It is hoped that the book could be used as a reference book for people who have at least some basics knowledge of science areas such as calculus, physics, etc.

This is a free textbook offered by Saylor Foundation. The Basics of General, Organic, and Biological Chemistry by David W. Ball, John W. Hill, and Rhonda J. Scott is a new textbook offering for the one-semester GOB Chemistry course. The authors designed this book from the ground up to meet the needs of a one-semester course. It is 20 chapters in length and approximately 350-400 pages; just the right breadth and depth for instructors to teach and students to grasp. In addition, The Basics of General, Organic, and Biological Chemistry is written not by one chemist, but THREE chemistry professors with specific, complimentary research and teaching areas. David W. Ball’s specialty is physical chemistry, John W. Hill’s is organic chemistry, and finally, Rhonda J. Scott’s background is in enzyme and peptide chemistry. These three authors have the expertise to identify and present only the most important material for students to learn in the GOB Chemistry course.

This course introduces impact craters of the Earth. There are now 170 identified impact craters on the Earth, and this number is growing, ever since the well known discovery of Meteor Crater in 1920s. Currently, multi/inter disciplinary research studies of impact structures are getting conducted in fields like mineralogy, petrology, environmental geology and marine biology. This course is offered during the Independent Activities Period (IAP), which is a special 4-week term at MIT that runs from the first week of January until the end of the month.

Estimated Lesson Time: 95 Minutes

This resource is an introduction to polynomial vocabulary and naming of polynomials. It includes an interactive presentation using Pear Deck and a note taking sheet for students.

This resource was developed as a part of the Creating Lessons Using Transformative Technology - Platteville Public Schools OER grant.

This resource includes skill posters to help  students understand, practice, and master a variety of sport skills. For this example, I've chosen basketball. However, examples for volleyball, hockey, and rugby exist.  Each poster includes a QR Code which is broken down by skill level for students to view a demonstration of the skill along with an activity to practice it.

This task involves a fairly straightforward decaying exponential. Filling out the table and developing the general formula is complicated only by the need to work with a fraction that requires decisions about rounding and precision.

Learning Objectives:
Students will be able to:
✔ Describe several views
people hold about bats.
✔ Identify misconceptions
about a threatened species.
✔ Reflect on changes in their
attitudes about wildlife.
✔ Share natural history and
conservation knowledge
about bats.

You may recall the All-American Girls Professional Baseball League (AAGPBL) from the 1992 film, A League of Their Own starring Geena Davis and Tom Hanks. Who will ever forget that “there’s no crying in baseball!” But did you know the AAGPBL has deep roots in the upper Midwest, including Wisconsin? This online exhibit pairs research and primary sources, documenting the AAGPBL in Wisconsin.

This task describes two linear functions using two different representations. To draw conclusions about the quantities, students have to find a common way of describing them. We have presented three solutions (1) Finding equations for both functions. (2) Using tables of values. (3) Using graphs.

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.

Look inside a battery to see how it works. Select the battery voltage and little stick figures move charges from one end of the battery to the other. A voltmeter tells you the resulting battery voltage.

In the decades following the Civil War, the US military clashed with Native Americans in the West.  The Battle of Little Bighorn was one of the Native Americans most famous victories. In this lesson, students explore causes of the battle by comparing two primary documents with a textbook account.

Students explore the properties of composites using inexpensive materials and processing techniques. They create beams using Laffy Taffy and water, and a choice of various reinforcements (pasta, rice, candies) and fabricating temperatures. Student groups compete for the highest strength beam. They measure flexure strength with three-point bend tests and calculations. Results are compared and discussed to learn how different materials and reinforcement shapes affect material properties and performance.
