Es ms. chambers students were in science lab trying to identify standard biomolecules: carbohydrates, fats and proteins. during
the lab experience, assistant principal matthews came in to evaluate their teacher and the learning environment. ms. matthews
reacted positively to the fact that the students were conducting a hands-in investigation, but she reacted negatively to the overall
classroom environment. take a look at one lab group. justify ms. matthews concern. what is something ms. chambers should have
done before the lab began?
ms. chambers should have provided the appropriate lab gear. although the
students have on lab aprons and goggles, they are not wearing gloves.
students have on ta apron
before beginning the lab, ms. chambers should have cleared away all
debris and non-required materials. the best way to prevent accidents is to
eliminate hazards.
ms. chambers should have checked each student group before letting them
begin work. two students in this photo should modify their appearance to
maximize safety
ms. chambers should consider what is appropriate for the students to be
wearing. in stead of lab it would be best if the students wore lab
coats as well as gloves.
