To better understand electricity, students investigate the properties of materials based on their ability to dispel static electricity. They complete a lab worksheet, collect experimental data, and draw conclusions based on their observations and understanding of electricity. The activity provides hands-on learning experience to safely explore the concept of static electricity, learning what static electricity is and which materials best hold static charge. Students learn to identify materials that hold static charge as insulators and materials that dispel charge as conductors. The class applies the results from their material tests to real-world engineering by identifying the best of the given materials for moving current in a solar panel.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer. Most common batteries--such as car batteries and the batteries inside a flashlight--work on the same principle that the pickle battery works on: two metals suspended in an ion-rich liquid or paste separate an electric charge, creating an electrical current around a circuit. In this activity, the pickle provides the ion-rich liquid - pickles contain salt water, which is rich in ions.

Students are introduced to the correct technical vocabulary for lighting, which is different than layperson's terms. They learn about lamp (light bulb) technology and how to identify the various types of lighting in their spaces. They are also introduced to lighting controls as a means for saving energy- reducing costs, human energy consumption, and greenhouse gas emissions on the environment. Using an accompanying worksheet, students embark on a guided audit in which they survey the lighting in their classroom and identify the potential savings from using controls.

During a power failure, or when we go outside at night, we grab a flashlight so we can find our way. What happens inside a flashlight that makes the bulb light up? Why do we need a switch to turn on a flashlight? Have you ever noticed that for the flashlight to work you must orient the batteries a certain way as you insert them into the casing? Many people do not know that a flashlight is a simple series circuit. In this hands-on activity, students build this everyday household item and design their own operating series circuit flashlights.

Students are introduced to circuits through a teacher demonstration using a set of Christmas lights. Then students groups build simple circuits using batteries, wires and light bulbs. They examine how electricity is conducted through a light bulb using a battery as a power source. Students also observe the differences between series and parallel circuits by building each type.

Fabrication laboratories (FabLabs) are utilized to materialize concepts. They can improve cognitive and creative abilities when used in a design-learning situation. Numerous studies have attempted to comprehend the relationship between makerspaces and creativity in a variety of disciplines, with the capacity to generate innovative consequences in makerspaces dependent on creativity. However, a comprehensive study that provides a holistic perspective on the contributions of labs as inclusive places that stimulate creativity for people with disabilities is absent. In order to address this study gap, the paper that follows provides an overview of FabLabs, makerspaces, and creativity and introduce the first of its kind MadaFabLab, as the first inclusive fablab in the world designed and tailored for innovators with disabilities “MadaFabLab”. The studies revealed that fablabs contribute to the development of creative person, product, physical, and social surroundings, as well as creative process. In addition, the MadaFabLab, a novel inclusive idea, fosters problem-solving, collaborative, and communication skills, and offers appealing locations and tools for the development of creative solutions to real-world challenges and needs identified by people with disabilities. We identified and analyzed five important themes pertaining to technical skills, technological and environmental factors, STEM learning, and skill development, and focused on their significance for fostering creativity in an inclusive FabLab.

As part of a design challenge, students learn how to use a rotation sensor (located inside the casing of a LEGO® MINDSTORMS ® NXT motor) to measure how far a robot moves with each rotation. Through experimentation and measurement with the sensor, student pairs determine the relationship between the number of rotations of the robot's wheels and the distance traveled by the robot. Then they use this ratio to program LEGO robots to move precise distances in a contest of accuracy. The robot that gets closest to the goal without touching the toy figures at the finish line is the winning programming design. Students learn how rotational sensors measure distance, how mathematics can be used for real-world purposes, and about potential sources of error due to gearing when using rotation sensor readings for distance calculations. They also become familiar with the engineering design process as they engage in its steps, from understanding the problem to multiple test/improve iterations to successful design.

A technician is only as accurate as the measurement equipment they are using. If the equipment is used incorrectly or is faulty, then the measurements will be inaccurate. If the measurements are inaccurate, then the technician will draw the wrong conclusions. To avoid getting inaccurate readings, you need to handle, use, and store meters properly. When you are done using a multimeter, it should always be turned off to extend battery life.

Students' understanding of how robotic touch sensors work is reinforced through a hands-on design challenge involving LEGO MINDSTORMS(TM) NXT intelligent bricks, motors and touch sensors. They learn programming skills and logic design in parallel as they program robot computers to play sounds and rotate a wheel when a touch sensor is pressed, and then produce different responses if a different touch sensor is activated. Students see first-hand how robots can take input from sensors and use it to make decisions to move as programmed, including simultaneously moving a motor and playing music. A PowerPoint® presentation and pre/post quizzes are provided.
