Apply knowledge of the interactions between charged particles to guide an object through a maze.
Compare the surface charges on various molecules and explore which atom types tend to cause uneven sharing of electrons.
Investigate the difference in attractive force between polar and non-polar molecules by “pulling” apart pairs of molecules. While all molecules are attracted to each other, some attractions are stronger than…
Explore the role of charge in interatomic interactions. The forces attracting neutral atoms are called Van der Waals attractions, which can be weak or strong, depending on the atoms involved….
Explore how different elements come together to form bonds and compare changes in potential energy and forces.
All cells, organs and tissues of a living organism are built of molecules. Some of them are small, made from only a few atoms. There is, however, a special class…
Students explore two new scenarios that involve solving systems of equations. The first situation involves the travel time for a round trip on an airplane, while the second situation involves…
This activity challenges the user to create a circuit that implements the function of a full adder. The circuit takes three bits as inputs and outputs their sum as two…
This activity challenges the user to wire up a circuit consisting of three PIC chips, a keypad, and a seven-segment display, in such a way that clicking on any digit…
