Students learn about rotary encoders and discover how they operate through hands-on experimentation. Rotary encoders are applied in tools to determine angle measurements and for translations of angular motion. One common rotary encoder application is in a computer's ball-type mouse—the ball itself is a type of rotary encoder. In this activity, students experiment with two rotary encoders, including one from a computer mouse and one created using a LEGO® MINDSTORMS® NXT kit. They collect data to define and graph the relationship between the motion of the rotary encoder and its output.

This online, facilitated course is designed for high-school educators wishing to teach global climate change using an inquiry/problem-based approach. The course focusses on evidence that supports global climate change and how to use NASA data and resources to help high-school students discover mitigations or adaptations to climate change. The course is part of PBS Education's outreach and offerings to educators across the country; it is a 45-hour experience over six weeks and eligible for three graduate credits.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

This kinesthetic activity simulates the process of evolution by natural selection. Students take on the roles of crab-like predators that exhibit one of four variants of feeding appendage: a spoon, fork, knife, and chopsticks. The simulation runs for three trials, as the predators use their appendages to harvest pinto beans, with varying success. Students track the frequency of each appendage type through three generations. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Students use data acquisition equipment to learn about force and displacement in regard to simple and complex machines. In the engineering world, materials and systems are tested by applying forces and measuring the resulting displacements. The relationship between the force applied on a material, and its resulting displacement, is a distinct property of the material, which is measured in order to evaluate the material for correct use in structures and machines.

Students build and use a very basic Coulter electric sensing zone particle counter to count an unknown number of particles in a sample of "paint" to determine if enough particles per ml of "paint" exist to meet a quality standard. In a lab experiment, student teams each build an apparatus and circuit, set up data acquisition equipment, make a salt-soap solution, test liquid flow in the apparatus, take data, and make graphs to count particles.
In a toy model of a cell, protein X is produced according …
In a toy model of a cell, protein X is produced according to a translation rate coefficient and eliminated according to a degradation rate coefficient. The protein copy number at which the rates for these processes balance is called the steady-state level, and the time it takes for a cell initially containing zero copies of protein X to accumulate half the steady-state level is called the _ŃŇrise time._Ń Surprisingly, the "rise time" depends on the degradation rate coefficient only. The classic textbook presentation of this topic is found in Alon, An Introduction to Systems Biology: Design Principles of Biological Circuits, Boca Raton: Chapman & Hall/CRC, 2007 (p. 18-22).

Through this unit, written for an honors anatomy and physiology class, students become familiar with the human skeletal system and answer the Challenge Question: When you get home from school, your mother grabs you, and you race to the hospital. Your grandmother fell and was rushed to the emergency room. The doctor tells your family your grandmother has a fractured hip, and she is referring her to an orthopedic specialist. The orthopedic doctor decides to perform a DEXA scan. The result show her BMD is -3.3. What would be a probable diagnosis to her condition? What are some possible causes of her condition? Should her daughter and granddaughter be worried about this condition, and if so, what are measures they could take to prevent this from happening to them?

Students will learn about bone structure, bone development and growth, and bone functions. Later, students will apply this understanding to answer the Challenge Question presented in the "Fix the Hip" lesson and use the acquired learning to construct an informative brochure about osteoporosis and biomedical engineering contributions to this field.

This collection of activities is based on a weekly series of space science mathematics problems distributed during the 2012-2013 school year. They were intended for students looking for additional challenges in the math and physical science curriculum in grades 5 through 12. The problems were created to be authentic glimpses of modern science and engineering issues, often involving actual research data. The problems were designed to be one-pagers with a Teacher‰Ûªs Guide and Answer Key as a second page.

This lab demonstrates Hooke's Law with the use of springs and masses. Students attempt to determine the proportionality constant, or k-value, for a spring. They do this by calculating the change in length of the spring as different masses are added to it. The concept of a spring's elastic limit is also introduced, and the students test to makes sure the spring's elastic limit has not been reached during their lab tests. After compiling their data, they attempt to find an average value of the spring's k-value by measuring the slopes between each of their data points. Then they apply what they've learned about springs to how engineers might use that knowledge in the design of a toy that enables kids to jump 2-3 feet in the air.
