This resource from Johns Hopkins University has audio and interactive components. Various forms of the Fourier series description for periodic signals are based on alternate ways of writing a cosine signal. This resource goes over Phasors, Phasor Sums, Harmonic Phasor Sums, Gibbs Effect, Windowing,...

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity to compare the amount of energy given off in combustion reactions. The experiment has two different objectives. The first is the comparison of heat energy given off between different fuel sources and the second is...

This 5-page resource, from the STEM Guitar Project, is an activity on acoustic resonance. "... this activity will explore how the hollow body of a guitar/ukulele works as an acoustic resonator, as well as what these instruments have in common with the Helmholtz resonator. This activity has the...

This 21-page paper, provided by Georgia Tech Research Institute, discusses a new curriculum from Georgia Tech that attempts to bring the maker movement to high school students. "The curriculum is structured around engineering standards and learning goals that reflect design and advanced...

This 2-page case study, provided by the National Institute for Women in Trades, Technology and Science, discusses the program coordinator at Techbridge and her efforts to teach fourteen high school girls engineering and computer science principles. These students studied circuitry, bridge building,...

“Excite Camp” is an annual program designed to build self-efficacy and bolster an interest in STEM in middle school Hawaiian girls. In 2008, 100% of participants surveyed reported that the camp experience increased their confidence/interest in math and science.

The Materials Science and Technology Teacher's Workshop (MAST) provides this lesson plan which will help students understand how temperature affects the conductivity, or resistance, of a variety of electrical materials and devices. The basic scientific principles of heat, metals and semiconductors...

The Materials Science and Technology Teacher's Workshop (MAST) provides this lesson plan for students learning about concrete. The class will "calculate the amount of water that reacts during hydration when cement becomes concrete under differing curing temperatures and observe the pH change that...

The Materials Science and Technology Teacher's Workshop (MAST) provides this lesson plan for students learning about concrete. The purpose of the activity is to "determine the density of a concrete sample and to learn the effect of various types of aggregates on concrete's density." The experiment...

This 1-page document provided by AgrowKnowledge includes a template and instructions for doing a lab write-up. This template explains that "Writing a report clarifies and reinforces the concepts of the lab." The following sections are included: Introduction, Materials and Methods, Results and...
