  47. Lab Skills Pre-Assessment: Making Data Tables Overview: • One important skill in designing and conducting lab experiments is to create a data table that serves as an organized way to collect the data from your experiment. Purpose: • To practice making data tables that are both organized and appropriate for a given experiment. • This is important preparation for our McMush lab at the end of this week, and will give your biology teachers valuable feedback about how well you are able to accomplish this task on your own. Instructions: • Read each experiment description, then draw a data table in the space provided.

  50. McPre-Lab • Sit with your lab partner • Individually: • Actively Read the Introduction and Procedure sections of the lab (underline key points, annotate in the margins, etc.) • Note: the Procedure has 3 sections • This should take about 15 min. • With your partner: • Answer the pre-lab questions (20 min) • These can not be answered by pulling direct sentences from the lab… they require some thinking. • Whole class: • Reviewing Part I and Part II (10 min)
