Product Details

Oh, my aching head! I need some pain reliever, but which brand of aspirin should I take? Students will:

• Experimentally determine the aspirin content of three brands of over-the-counter pain relievers using acid–base neutralization titration techniques and then compare the amounts to those listed on the bottle.
• Compare the effects of regular, buffered and enteric-coated aspirin on a “simulated stomach.”
• Compare the actual amount of aspirin and cost-effectiveness of each tablet and then make comparisons and draw conclusions about different brands of aspirin.
• Learn the history and chemistry of aspirin as well as about the different types on the market with the extensive background material.

Teacher Notes and reproducible student handouts included. All aspirin samples, chemicals and specialized equipment are provided in the kit. Complete for 30 students working in pairs.

Performance Expectations

HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
HS-PS2-6. Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
