Helping Children Learn Mathematics
Results from national and international assessments indicate that school children in the United States are not learning mathematics well enough. Many students cannot correctly apply computational algorithms to solve problems. Their understanding and use of decimals and fractions are especially weak. Indeed, helping all children succeed in mathematics is an imperative national goal. However, for our youth to succeed, we need to change how were teaching this discipline. Helping Children Learn Math

Nickel Karate
How can a quarter be removed from the bottom of a stack of quarters without lifting or moving the other coins? This material is part of a series of hands-on science activities designed to arouse student interest. Here students investigate the properties of inertia and Newton's first law of motion. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of applicable K-12 national science education standards. Also provid

Implementing Biomimicry and Sustainable Design with an Emphasis on the Application of Ecological Pri
This unit provides students with an opportunity to study ecological relationships with an emphasis on the Sonoran Desert. Students appreciate the complexity and balance that supports the exchange of energy and matter within food webs. Species adaptations are examined. Students then apply these natural relationships to the study of biomimicry and sustainable design. They study the flight patterns of birds and relate their functional design to aeronautical engineering. They are presented with a Ch

Designing a Medical Device to Extract Foreign Bodies from the Ear
Students learn the engineering design process by actually utilizing the steps, from identification of the problem to designing a device and evaluating its efficacy and areas for improvement. A quick story at the beginning of the activity reveals the problem: a small child put a pebble in his ear and we donâ€™t know how to get it out! As biomedical engineers, the students are asked to design a device to remove it. Each student pair is provided with a model ear canal and a wide variety of classroo

A New Angle on PV Efficiency
Students examine how the orientation of a photovoltaic (PV) panel relative to the sun affects the efficiency of the panel. Using sunshine (or a lamp) and a small PV panel connected to a digital multimeter, students vary the angle of the solar panel, record the resulting current output on a worksheet, and plot their experimental results.

In and Out Reactor
Students learn about material balances, a fundamental concept of chemical engineering. They use stoichiometry to predict the mass of carbon dioxide that escapes after reacting measured quantities of sodium bicarbonate with dilute acetic acid. Students then react the chemicals in a small reactor made from a plastic water bottle and balloon.

Bone Density Challenge Introduction
Students are introduced to the challenge question, which revolves around proving that a cabinet X-ray system can produce bone mineral density images. Students work independently to generate ideas from the questions provided then share with partners and then with the class as part of Multiple Perspectives. As part of the associated Activity 1, students then explore multiple websites to gather information about Bone Mineral Density and answer questions on a worksheet, then later take a quiz on the

The Grand Challenge: Simulating Human Vision
This lesson introduces the Robotics Peripheral Vision Grand Challenge question. Students are asked to write journal responses to the question and brainstorm what information they will need to answer the question. The ideas are shared with the class and recorded. Students then share their ideas with each other and brainstorm any additional ideas. Next students draw a basis for the average peripheral vision of a human being and then compare that range to the range of two different focal lengths in
