What Is an IR Sensor?

(View Complete Item Description)

Students learn about infrared energy and how it is used to sense the surrounding environment. They review where infrared falls on the electromagnetic spectrum and learn how infrared sensors work, as well as various ways engineers and scientists create and apply infrared technology to study science and collect information for security, communications, medical, research and other purposes. Pre/post-quizzes and a take-home assignment are provided. Learning the concepts prepares students to conduct the associated activity in which they design and program Arduino-controlled robots that use IR sensors to follow a line and make designated stops, much like the automated guided vehicles used in industry and commerce.

What is Wind Chill?

(View Complete Item Description)

This resource introduces the concept of wind chill, the formula used to measure it and relates it to the causes of hypothermia. A simple experiment using a pie pan, sand, fan and a thermometer demonstrates this concept. The 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.

Where is Fibonacci?

(View Complete Item Description)

Students discover the Fibonacci sequence and how it relates to a multitude of things in their world. They will begin to see "non-mathematical" things as mathematical. This is collection of activities that can be easily be used as a unit or as pieces to fit what you already have in place when teaching the Fibonacci sequence. Rubric definitely needs some work :)

Who are the Eastern Shoshone?

(View Complete Item Description)

Learn how and when the Eastern Shoshone came to Wyoming, what are the Shoshone values, and what are the people of the Eastern Shoshone like? In the accompanying lessons plans (found in the Support Materials), students will gain an understanding of the Fort Bridger Treaty of 1868 including its importance to the state of Wyoming and the Eastern Shoshone Tribe in 1868 and today. The American Bison, or Buffalo as preferred by most tribes, has a significant existence among the Native American people. For thousands of years, the great American Buffalo roamed the Great Plains, migrating from north to south, searching for areas on which to thrive. The Shoshone people depended on the buffalo for many things that included food, clothing, and shelter. Every part of the buffalo was used and provided for the people. LEARNING OBJECTIVES: Students will study (Highlight, paraphrase and report) the Treaty of 1868 between the Eastern Shoshone Tribe and the United States Government. Students will learn about the Eastern Shoshone people through the use of research and technology. Students will understand that the history of the Shoshone people in the Wind River Mountains dates back thousands of years. Students will understand that the circle of life continues in a perpetual cycle and is passed on through oral tradition. These stories often taught a lesson to young people. Students will understand the indigenous perspective of interconnectedness. Students will understand how bison populations were devastated by western expansion. Students will learn how to construct, read, compare and analyze different population graphs. Students will understand how the diets of the Shoshone people varied depending on the areas in which they lived. Students will acquire knowledge of the Wind River Reservation communities and be able to identify these locations on a map. Students will be able to further describe how their culture has shaped them. Students will be able to define the concept of culture. Students will be able to explain some of the attributes of culture.

Why do we do proofs?

(View Complete Item Description)

The aim of this session is to motivate students to understand why we might want to do proofs, why proofs are important, and how they can help us. In particular, the student will learn the following: proofs can help you to really see WHY a result is true; problems that are easy to state can be hard to solve (Fermat's Last Theorem); sometimes statements which appear to be intuitively obvious may turn out to be false (the Hospitals paradox); the answer to a question will often depend crucially on the definitions you are working with. Target audience: suitable for anyone with a knowledge of elementary algebra and prime numbers, as may be obtained by studying A level mathematics.

Why is There a Tidal Bulge Opposite the Moon?

(View Complete Item Description)

In this activity, students use mathematics to understand tides and gravitation and how gravity works across astronomical distances, using an apparatus made from a slinky, meter stick, and a hook. A description of the mathematical relationships seen in the demonstration is included. The 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.

circle

(View Complete Item Description)

A circle is a simple closed shape. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constantelements of the circle- raidus, diameter, segment, chord

hx Diagram (Mollier)

(View Complete Item Description)

Interactive hx diagram (Mollier) for displaying the changes in state of humid air at sensible temperature change, wet cooling, mixture air, humidification and custom state points. Automatic calculation of the required heat flow for cooling and heating. Free online tool, no registration required. More detailed information: To analyze changes of state of moist air normally a diagram with the specific enthalpy as the ordinate and the humidity ration as the abscissa is used. This specific type of diagram was proposed in 1923 by the German professor of applied physics and mechanics, Richard Mollier. The Mollier diagram is respectively created for a certain constant pressure, usually the atmospheric pressure (p≈1bar). The thermodynamic properties of moist air are represented in the state diagram as lines of constant state variables - so-called isolines.

pH Scale

(View Complete Item Description)

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
