Art, iPads and the Storm King Center

Widely celebrated as one of the world’s leading sculpture parks, Storm King Art Center has welcomed visitors from across the globe for fifty years. It is located only one hour north of New York City, in the lower Hudson Valley, where its pristine 500-acre landscape of fields, hills, and woodlands provides the setting for a collection of more than 100 carefully sited sculptures created by some of the most acclaimed artists of our time.
In late September, students in Class VIII Art visited the Center, iPads in hand, to sketch some of the installation pieces.

Here are some examples of the student's work.

iPads in AP Physics

Students in AP Physics arrive in class understanding vector algebra.  Three-dimensional vectors are written in unit vector notation.  For example, a position vector may be written as r = 6i + 2j - 3k.  However, students often have difficulty visually three-dimensional vectors.

Using the App "Vect Calc" students were able to enter specific three-dimensional vectors and see a representation of their vector on a 3D axis.  By entering two three-dimensional vectors, students could determine the dot (or scalar ) product and the cross (vector) product.  The resultant cross product vector is represented in space on the 3D axes.

iPads in Advanced Physics

A new school year brings an opportunity to extend and expand one's knowledge of core concepts learned in the past.  In Advanced Physics, students used the App "Graphicus" to learn how slopes of tangent lines vary for a function y(x).  Students then applied this understanding to the concept of the derivative in calculus.

Graphicus App

Students entered a function y(x), analagous to x(t) or v(t), and then the students, by moving the trace function along the curve, could determine how the first and second derivative change as a function of time.  Students then related this analysis to how the velocity and acceleration of an object would change if the inputted function represented x(t).
