Coaching • Your suggestions?

Coaching • Assume if there is an experiment, it will be quick and straightforward

Coaching • Assume if there is an experiment, it will be quick and straightforward • Talk to chemistry teachers and look online for examples/ideas of experiments

Coaching • Assume if there is an experiment, it will be quick and straightforward • Talk to chemistry teachers and look online for examples/ideas of experiments • Example – titration to determine concentration; probably eyedroppers or pasteur pipets (not biurets), look for color change, practice!

Coaching • Example – titration to determine concentration; probably eyedroppers or pasteur pipets (not biurets), look for color change, practice! • Practice answering questions on all topics; use chemistry textbooks, practice tests online

Coaching • Practice answering questions on all topics; use chemistry textbooks, practice tests online • Practice analyzing data from a variety of experiments; graph the data presented in a table and make conclusions
