Microchips are a man-made wonder. Investigate the manufacturing wonder with a hands-on inquiry-based instructional activity. Scholars simulate the process of pattern transfer using photoresist. Their conclusion identifies how their...

Here is a different approach to solutions: a instructional activity that has chemistry learners use words to describe them! This is an outstanding exercise that will stretch learners to show what they know. They answer questions...

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

Salts, solvents and hydroxides are listed and pupils will need to add information about a selection of electrolytes.  For a list of compounds, they indicate whether the solute particles will be ions or molecules and then the symbols...

In this conductivity learning exercise, students answer post lab questions about substances that transferred electrons resulting in electricity flowing through the conductivity leads use to test each substance.

Fifth graders construct a voltaic battery. They change chemical energy into electrical energy by inserting copper wire into a lemon. They discover the tingle of the wire on their tongue is due to the movement of electrons.
