Students investigate the effect of thin films to surface friction. In this physics lesson, students calculate the coefficient of friction using mathematical formulas. They discuss its importance in their everyday lives.

Young scholars explore friction. In this physics lesson plan, students will cover metal blocks with film to determine the changes caused by static and kinetic friction.

Babies grow at an incredible rate! Demonstrate how to model growth using a linear function. Learners build the function from two data points, and then use the function to make predictions.

Explore different types of functions using an interactive lesson. Learners enter functions and view the accompanying graphs. They can choose to show key features or adjust the scale of the graph.

Students investigate poverty using graphs. In this algebra lesson, students collect data on the effects of poverty and use different rules to analyze the data. They graph and use the trapezoid rule to interpret the data.

Students solve quadratic equations and identify the vertex. In this algebra lesson, students factor quadratic equations and identify the different properties of a parabola. They graph the functions using the vertex and intercepts.
