Scrappy Circuits
The best dollar you can spend on a child’s STEAM education is to take them to the dollar store, buy an electronic item, and then take it apart. Learning how a handheld fan, LED light, remote control, or headphones work will help show how wind turbines, traffic lights, speakers, keyboards, and other modern devices function. The next step is to take apart a dollar store item and make it better — combine two items, replace a switch, create something new and unique. Scrappy Circuits is the perfect way to get started. I first developed Scrappy Circuits with Chris Connors and Eva Luna while working at Xraise, an education outreach program at Cornell University. What began as an exploration of DIY switches ended later as a self-made invention system sourced from a fifty-cent LED tea light. Take Apart a Tea Light Open the battery compartment, remove the 3V coin cell battery, and pry the base/LED holder apart from the outer cylinder body.

Science and Technology of WWII
So What is This About? Teachers, here you will find classroom lesson plans related to the science and technology of WWII. Social studies and history teachers can use these lessons to imbue science and math into their classrooms. Science and math teachers can use these lessons to bring real-world applications to their theories and concepts. Feel free to adapt these lessons to best suit your classroom needs and environment. The D-Day invasion of June 6, 1944, has been called the climatic battle of World War II.

The Electric and Magnetic Personalities of Mr. Maxwell
Summary Students are briefly introduced to Maxwell's equations and their significance to phenomena associated with electricity and magnetism. Basic concepts such as current, electricity and field lines are covered and reinforced. Through multiple topics and activities, students see how electricity and magnetism are interrelated.

Whose Field Line Is It, Anyway?
Summary Students teams each use a bar magnet, sheet of paper and iron shavings to reveal the field lines as they travel around a magnet. They repeat the activity with an electromagnet made by wrapping thin wire around a nail and connecting either wire end to a battery. They see that the current flowing through a wire produces a magnetic field around the wire and that this magnetic field induced by electricity is no different than that produced by a bar magnet. The experience helps to solidify the idea that electricity and magnetism are deeply interrelated.
Static Cling
Summary This hands-on activity explores the concept of static electricity. Students attract an O-shaped piece of cereal to a charged comb and watch the cereal jump away when it touches the comb.
