Geogebra: Residuals and Linear Regression
If the line fits, use it. Using a Geogebra interactive, pupils plot points and try to find the best fit line. They assess the linear fit by analyzing residuals. A radio button allows participants to show the regression line and the...

Chemical Potential: Staircase Demonstration
It's all uphill from here! Scholars examine the pattern of random particle motion up a staircase. The simulation shows how the linear increase in energy corresponds to an exponential decrease in particle concentration.
Curated OER
Simultaneous Equations for Circuit Analysis
In this worksheet, students use Algebra to plot different solutions to equations and analyze schematics in order to answer a series of 25 open-ended questions about electrical circuits. This worksheet is printable and the answers are...
CK-12 Foundation
Linear Programming: Bakers' Dilemma
Place the pies in a line. Pupils create a graph of a system of linear inequalities to represent the number of pies a bakery can make. Learners analyze the vertices on the graph to determine the number of pies they can bake without...
Curated OER
Mixed Frequency Signals
In this electrical worksheet, students interpret schematics to answer a series of 31 questions about mixed frequency signals. This worksheet is printable and the answers are available on-line.
Concord Consortium
Concord Consortium: Stem Resources: Seeing Motion
With this interactive tool and the use of a motion sensor, students will track their own motion and, as they collect data in several experiments, they will plot it on a distance-time graph. After completing the three experiments, they...
