Levels of Connectivity

As an introduction to Steiner Trees, class members are challenged to find the shortest paths to connect multiple points. The teacher introduces the problem by showing how to connect three points. Groups then go outside and construct a...

What is the most efficient way to ensure everyone is connected? Individual pupils determine the least expensive route to pave roads in a fictional city. In doing so, they learn to find the minimal spanning tree for the situation. They...

Introduce gas laws using the popular topic of SCUBA diving. This activity makes a connection between the gas laws and the effect of pressure and temperature changes during diving. Young engineers complete introductory experiments to...

Young scholars predict whether road, rail, waterway, air, or telecommunications is best way to connect Canada, and justify their choices taking into consideration environmental and economic concerns. Students then compare mass of...

Help your class make a connection between salt water and nanoscience. In the introductory lesson of a seven-part unit, the class explores why salt water helps a sore throat feel better. Pupils conduct preliminary research about the...

Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear functions with...

The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value of...

Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...

It may look a lot like magic, but it's really just science! Young scientists build a solar-powered motor using household materials. They discover a connection between density and solar power as their motors turn the blades of a pinwheel.
