Levels of Connectivity

Collaborative groups connect resistors and solar panels in series and measure electrical resistance, voltage, and current. The objective is to order 16 solar panels from strongest to weakest. They graph current-voltage and power curves...

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...

Here's a lesson that is simply a-MAZE-ing! Introduce science scholars to pipeline systems through a hands-on project. Partnered pupils participate in the design, construct, and test a PVC pipeline maze. Reusable materials and clear...

Looking for an engineering project that will tower above the rest? Try a design experiment that has built-in fun! Groups examine a variety of skyscraper designs, then compete to create their own slender towers. The teacher's guide is...

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...

Consider the relationship between side length and area as an input-output function. Scholars create input-output tables for the area of squares to determine an equation in the first installment of a three-part unit. Ditto for the area of...
