Aspirin Analysis
Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand.

Condensation Polymerization: Preparation of Nylon 6/6
Students participate in a lab activity in which they synthesize nylon 6/6, calculate the percent yield by mass, identify the polymer as thermoplastic or thermoset, and determine the melting point, density and end-product use of the polymer.
