What a bright idea! Working in groups, scholars design a solar phone charger by applying concepts from the unit. They use solar modules and buck and boost converters in their creations, which must be able to charge a phone after...

Provide the spark to foster a love of science. Instructors perform a demonstration that uses a camping stove to generate electricity to charge a phone. Pupils use data from the experiment to the calculate the efficiency of the stove....

The power to learn about AC and DC power lies within everyone. The fifth of seven installments in the Off the Grid unit continues the investigation of the efficiency of a USB charger. Individuals use an inverter that converts DC power to...

Boost one's knowledge of converters. The fourth of seven installments in the Off the Grid unit looks at buck and boost converters, which lower and raise the input voltage. Scholars apply the converters to adjust the output voltage to...

Be efficient in learning about efficiency. A fun hands-on activity has pupils calculate the efficiency of cell phone chargers by measuring the power in and power out. They also learn how to read and use circuit diagrams.

It's pass or fail, and one must pass to move on to the next lesson—no pressure. The second of seven installments in the Off the Grid unit has pupils demonstrate their knowledge of vocabulary as well as the process of using a multimeter....

It's much more efficient if everyone knows the relevant terms. Pupils research vocabulary terms related to electric currents to start a unit on solar energy. They then use a multimeter to measure the voltage and current for a solar...

String up a message. Pupils string together colored beads to code a word or short phrase. Each color represents one of the four DNA bases. Using a combination of three bases, learners create an amino acid that stand for each letter of...

The term periodic in periodic table has meaning. Young scientists view a video to learn about the periodic table and then use the provided resources to create their own tables. They focus on patterns of the chemical properties of each...

Let cooler heads prevail. Future engineers first learn about heat transfer and insulation. They then design and build a contraption that will prevent an ice cube from melting for as long as possible.

Keep one's dream of becoming an engineer afloat. Learners apply the engineering design process to build a boat out of aluminum foil. They start with a square boat, then consider whether boats of different shapes would be able to hold...

Water, water, everywhere, but pollution is a major problem. Scholars design a filtration device or process that removes dirt and other particles from water. They use various household objects such as marbles, cotton balls, or coffee...

Match my cereal sequence. Pupils view a sequence made by colorful cereal rings and create copies of it. Learners must either remember or write down the sequence to transport the code to another location. Scholars replicate the cereal...

Compare sizes of microscopic items. Given a set of labels of microscopic objects, pupils try to place them in order from smallest to largest. Scholars then compare their lists to the actual comparisons along with the measurements of the...

Soap, suds, and cell membranes. Pupils create a model of a cell membrane by using soap films. They experiment with trying to pass different objects through the film without popping it. Using a tube, they create a passageway through the...
