Students explore questions which cannot be handled with simple pendulums, and examine both the usefulness and the limitations of approximations in science. A Java applet created from a Stella model is included.

Eighth graders investigate linear equations.  For this Algebra I lesson, 8th graders explore the effects that manipulating a linear equation has on the graph of the function through the use of a java applet.

Students investigate the Sierpinski triangle and calculate the ratio and area of the triangle. In this fractals lesson plan, students calculate parts of a Sierpincki triangle. They use Google Earth to help them construct the different...

Students predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive lesson.

Learners rewrite equations using algebraic symbols. In this algebra lesson, students graph linear equations using the slope and y intercept. They make predictions about their graphs and analyze the results.

Students examine the influence of the end wall. They find a basin size and wind speed such that a given wall height is overtopped. Then, increase the wall elevation until overtopping stops. Students explain the difference in results.
