Soil moisture-sensing by hacking a solar light Contributors: Sarah Al-Mutlaq Share Use this URL to share: Share on Twitter Share on Facebook Share on Google+ In this tutorial, we are going to take a simple solar powered pathway light from a department store and rewire it to be a soil moisture sensor. The finished design will turn on an LED when the soil dries up. For this tutorial, I purchased a $2 solar pathway light from McGuckins Hardware, but most any standard solar pathway light should do the trick.

Educational Resources for Studying Graphic Design - Noupe Design Blog Feb 14 2011 One of the greatest things about having access to the Internet, is the educational opportunities that it affords the public. People in all professions have the ability to expand their knowledge base through the wealth of information being shared via the Internet, and the same holds true for those who are studying graphic design. The Internet is positively bursting with tutorials and resources that can help one advance through the various stages of becoming a successful graphic designer. All the way, from a newbie to an experienced pro. Today, that is our purpose here.

It’s Electric Unit Overview: Students will learn about electricity and circuits. Grade Level: Projects: The hidden beauty of pollination: Louie Schwartzberg on TED Live from TED2014 Mysteries of the unseen world: Louie Schwartzberg at TED2014 Louie Schwartzberg is fascinated with exposing the world’s wonders through photography. Three years ago, his talk, “Nature. Beauty. Gratitude,” demonstrated his uncanny ability to capture the captivating beauty of our natural world — the tiniest shake of a flower petal, the stirring complexity of a bee’s wing. Wind Power: Creating a Wind Generator The lesson presented here focuses on the engineering design process and its use in identifying a question (solving a problem), developing a design or change in design, testing that design, observing and collecting data, analyzing the data recorded from the experiment, and forming a conclusion to perform another round of design. In this case, we are attempting to maximize the voltage obtained from a wind-driven turbine through the use of several experimental designs. You may want to review the following multimedia presentations to learn more about STEM and the engineering design process.

Ballistic Flight Equations The study of model rockets, the flight of a baseball, or the "bend" of a soccer kick are excellent ways for students to learn the basics of forces and the response of an object to external forces. A ball in flight has no engine to produce continuous thrust and the resulting flight is similar to the flight of shell from a cannon, or a bullet from a gun. This type of flight is called ballistic flight and on this page we present the equations that describe ballistic flight. Ballistic flight only occurs under the ideal conditions that weight is the only force acting on the object. There is no thrust and no aerodynamic drag acting on an object in ballistic flight. Such flight conditions would occur on the Moon, where there is no atmosphere to produce drag.

The Tinkering Studio Using a concentric design and resistive dough, cool parallel circuits are possible All the ingredients that you need to make your own conductive and resistive Play-Doh Wrap the dough in plastic film and store in ziploc bags to keep it moist longer Soda Bottle Rocket LED Fireworks Originating in China, fireworks have been around since before the 16th Century and have been making people look to the night sky with delight. Firework formulas are closely guarded secrets handed down from generation to generation and the overall concept has not changed much over the centuries. Mix chemicals compounds, place them in a delivery device, light a fuse, and watch the fun.
