I’ve been a middle school science teacher for 26 years and I find LabLearner to be complete enough for the novice teacher and comprehensive enough for the veteran, it is literally everything you need. Students enjoy high interest, inquiry based lab work. Their workbooks narrow the focus, procedures, pre and post questions to the essential information. The CELLS are well-constructed and cohesive units that spiral previously taught information/skills onto the next level. LabLearner provides wonderful support and perspective; questions and emails are answered timely.
